Description

Die Erfindung betrifft einen Kältemittelkompressor, umfassend eine Motoreinheit, welche einen Motor und einen von einem äußeren Kühlkanalanschluß ausgehenden Kühlkanal für den Motor aufweist, sowie eine Verdichtereinheit, welche eine Verdichterstufe mit einem Verdichterstufeneinlaß und einen Verdichterstufenauslaß und einen von einem äußeren Ansauganschluß ausgehenden Ansaugkanal aufweist, welcher wie der Kühlkanal zu dem Verdichterstufeneinlaß geführt ist.The invention relates to a refrigerant compressor, comprising a motor unit, which is a motor and one by one outer cooling duct connection outgoing cooling duct for the engine has, and a compressor unit, which has a compressor stage with a compressor stage inlet and a compressor stage outlet and one from an external suction port outgoing intake duct, which like the Cooling channel is led to the compressor stage inlet.

Derartige Kältemittelkompressoren sind aus dem Stand der Technik bekannt, siehe z.B. das Dokument US-A-5 007 809. Bei diesen ist das Rohrleitungssystem für das Sauggas entweder zum Kühlkanalanschluß oder zum Ansauganschluß zu führen, je nach dem, welche Art der Kühlung bei der Motoreinheit realisiert werden soll.Such refrigerant compressors are from the prior art Technique known, see e.g. document US-A-5 007 809. In these the piping system is for the suction gas either to the cooling duct connection or to the suction connection to perform, depending on what type of cooling the motor unit is to be realized.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Kältemittelkompressor der gattungsgemäßen Art derart zu verbessern, daß die Kühlung variabel mit möglichst geringen baulichen Änderungen realisierbar ist.The invention is therefore based on the object of a refrigerant compressor to improve the generic type in such a way that the cooling is variable with as little as possible structural changes can be realized.

Diese Aufgabe wird bei einem Kältemittelkompressor der gattungsgemäßen Art erfindungsgemäß dadurch gelöst, daß eine äußere Anschlußeinheit vorgesehen ist, an welcher der Kühlkanalanschluß und der Ansauganschluß angeordnet sind, daß die Anschlußeinheit eine Aufnahme und ein Einstellteil aufweist, welches in mindestens zwei unterschiedlichen Stellungen in die Aufnahme einsetzbar ist und daß durch die verschiedenen Stellungen des Einstellteils die dem Kühlkanalanschluß und dem Ansauganschluß zugeführten Anteile von der Gesamtmenge des über einem äußeren Sauggasanschluß zugeführten Sauggases unterschiedlich einstellbar sind.This is the task of a refrigerant compressor Generic type according to the invention solved in that a External connection unit is provided, on which the cooling duct connection and the suction port are arranged that the Connection unit has a receptacle and an adjustment part, which in at least two different positions the recording can be used and that through the different Positions of the adjustment part of the cooling duct connection and parts of the total quantity supplied to the suction connection of the suction gas supplied via an external suction gas connection can be set differently.

Der Vorteil der erfindungsgemäßen Lösung ist somit darin zu sehen, daß bei dem Kältemittelkompressor ein einziger Sauggasanschluß vorgesehen ist, zu dem die Rohrleitung für das Sauggas zu führen ist und daß je nach Einsatzbereich eine unterschiedliche Art der Kühlung, nämlich unterschiedlich starke Sauggaskühlung der Motoreinheit bis hin zur ausschließlichen Luftkühlung der Motoreinheit, in einfacher Weise lediglich durch geänderten Einbau des Einstellteils erfolgen kann. Das heißt, daß durch Variation des Anteils des Sauggases, welches in den Kühlkanalanschluß einströmt, und des Anteils des Sauggases, welches in den Ansauganschluß einströmt, die Kühlung der Motoreinheit durch das Sauggas in Anpassung an den jeweiligen Einsatzfall einstellbar ist.The advantage of the solution according to the invention is thus too see that in the refrigerant compressor, a single suction gas connection is provided to which the pipeline for Suction gas is to be carried and that depending on the area of application different kind of cooling, namely different strong suction gas cooling of the motor unit up to exclusive Air cooling of the motor unit, in simple Only by changing the installation of the adjustment part can be done. This means that by varying the proportion of the Suction gases, which flows into the cooling duct connection, and the proportion of the suction gas that flows into the intake connection, the cooling of the motor unit by the suction gas in Adaptation to the respective application is adjustable.

Damit läßt sich unabhängig davon, welche Art der Kühlung der Motoreinheit realisiert werden soll, ein Einbau des Kältemittelkompressors standardisiert vorbereiten.It can be used regardless of the type of cooling Motor unit to be realized, an installation of the refrigerant compressor prepare standardized.

Eine besonders günstige Lösung sieht vor, daß in einer der Stellungen mit dem Einstellteil eine Verbindung zwischen einem äußeren Sauggasanschluß und dem Kühlkanalanschluß und in einer anderen der Stellungen mit dem Einstellteil eine Verbindung zwischen dem Sauggasanschluß und dem Ansauganschluß herstellbar sind.A particularly favorable solution provides that in one of the Positions with the adjustment part a connection between an outer suction gas connection and the cooling duct connection and in another of the positions with the adjustment part one Connection between the suction gas connection and the suction connection are producible.

Damit ist die Möglichkeit einer Einstellung einer im wesentlichen ausschließlichen Sauggaskühlung und einer im wesentlichen ausschließlichen Luftkühlung der Motoreinheit gegeben. So the possibility of hiring one is essentially exclusive suction gas cooling and one essentially exclusive air cooling of the motor unit.

Die Art der Stellungen, in welchen das Einstellteil in die Aufnahme einsetzbar sein soll, ist im Zusammenhang mit der bislang beschriebenen erfindungsgemäßen Lösung nicht näher spezifiziert. Beispielsweise ist es denkbar, das Einstellteil in zwei durch eine Translationsbewegung sich unterscheidende Stellungen einzubauen. Dies hat jedoch den Nachteil, daß die zwei Stellungen des Sauggasanschlusses sich ebenfalls durch ihre räumliche Anordnung unterscheiden.The type of positions in which the setting part in the Recording should be used is in connection with the No solution according to the invention described so far specified. For example, it is conceivable for the adjustment part in two differing by a translational movement To install positions. However, this has the disadvantage that the two positions of the suction gas connection also through distinguish their spatial arrangement.

Aus diesem Grund sieht eine besonders vorteilhafte Lösung vor, daß das Einstellteil in um eine Symmetrieachse des Sauggasanschlusses gedrehten Stellungen in die Aufnahme einsetzbar ist. Diese Lösung hat den Vorteil, daß durch die Drehung um eine Symmetrieachse des Sauggasanschlusses die Symmetrieachse des Sauggasanschlusses selbst lokal unverändert stehen bleibt und somit die zum Sauggasanschluß führenden Rohrleitungen ebenfalls unabhängig von der Art der Kühlung der Motoreinheit zum selben Ort zu führen sind.For this reason sees a particularly advantageous solution before that the adjusting part in about an axis of symmetry of the suction gas connection rotated positions can be used in the holder is. This solution has the advantage that the rotation the axis of symmetry about an axis of symmetry of the suction gas connection of the suction gas connection itself remain unchanged locally remains and thus the pipes leading to the suction gas connection also regardless of the type of cooling of the Motor unit must be brought to the same place.

Diese Lösung ist insbesondere dann günstig, wenn der Sauggasanschluß rotationssymmetrisch ausgebildet ist, so daß die Möglichkeit besteht, die beiden Stellungen des Einstellteils durch zwei relativ zueinander grundsätzlich beliebig verdrehte Stellungen zu realisieren.This solution is particularly favorable when the suction gas connection is rotationally symmetrical, so that the Possibility, the two positions of the setting part by two basically twisted relative to each other Realize positions.

Hinsichtlich der Art des Einbaus des Einstellteils wurden bislang ebenfalls keine näheren Angaben gemacht. So wäre es beispielsweise denkbar, die Anschlußeinheit so auszubilden, daß nach Öffnen des Kompressorgehäuses das Einstellteil in der entsprechenden Stellung montierbar ist. Um dieses umständliche Öffnen des Kompressorgehäuses jedoch zu vermeiden, ist vorzugsweise vorgesehen, daß das Einstellteil über eine äußere Öffnung der Anschlußeinheit in die Aufnahme einsetzbar ist.Regarding the type of installation of the adjustment part so far no further details have been given either. So it would be for example conceivable to design the connection unit in such a way that after opening the compressor housing in the adjustment part the corresponding position can be mounted. About this cumbersome However, to avoid opening the compressor housing it is preferably provided that the adjusting part has a outer opening of the connection unit can be inserted into the receptacle is.

Damit läßt sich einerseits das Einstellteil leicht austauschen und andererseits in einfacher Weise in die beiden Stellungen bringen, ohne daß Manipulationen an dem Kältemittelkompressor selbst erforderlich sind.On the one hand, this makes it easy to replace the setting part and on the other hand in a simple way in the two Bring positions without tampering with the refrigerant compressor themselves are required.

Bislang wurde nicht im einzelnen spezifiziert, wie die Anschlußeinheit selbst ausgebildet sein soll. Beispielsweise wäre es denkbar, die Anschlußeinheit so auszubilden, daß das Einstellteil mit einem außerhalb der Aufnahme liegenden Element die Verbindung zwischen dem Sauggasanschluß und dem Ansauganschluß oder dem Kühlkanalanschluß herstellt. Eine besonders günstige Lösung sieht vor, daß die Aufnahme einen Innenraum aufweist, in welchem der Kühlkanalanschluß und der Ansauganschluß münden und daß in jeder der Stellungen des Einstellteils entweder der Kühlkanalanschluß oder der Ansauganschluß abdeckbar sind. Diese Lösung hat somit den Vorteil, daß sie sehr kompakt baut, da das Verschließen des Kühlkanalanschlusses oder des Ansauganschlusses durch einen in den Innenraum eingreifenden Bereich des Einstellteils erfolgt.So far it has not been specified in detail how the Connection unit itself should be designed. For example it would be conceivable to design the connection unit so that the Adjustment part with an outside of the recording Element the connection between the suction gas connection and the Intake connection or the cooling duct connection. A particularly favorable solution provides that the recording one Has interior, in which the cooling duct connection and Intake connection open and that in each of the positions of the Adjustment part either the cooling duct connection or the intake connection can be covered. This solution therefore has the advantage that it is very compact because the cooling duct connection is closed or the suction port through a in the Interior engaging area of the adjusting part takes place.

Eine besonders günstige Lösung sieht vor, daß der Innenraum der Aufnahme eine ungefähr zylindrische Form aufweist, da sich in diesem Fall das hierzu entsprechende Einstellteil einfach herstellen läßt.A particularly favorable solution provides that the interior the receptacle has an approximately cylindrical shape because in this case the corresponding setting part easy to manufacture.

Eine besonders vorteilhafte Lösung sieht dabei vor, daß der Innenraum der Aufnahme sich als Ausnehmung in eine Trennwand hineinerstreckt, welche den Kühlkanal und den Ansaugkanal voneinander trennt, da sich in diesem Fall der Kühlkanalanschluß und der Ansauganschluß besonders günstig so anordnen lassen, daß sie in den Innenraum münden.A particularly advantageous solution provides that the Interior of the recording itself as a recess in a partition which extends the cooling duct and the intake duct separates from each other, because in this case the cooling duct connection and arrange the suction port so cheap let them flow into the interior.

Eine hinsichtlich der kompakten Bauweise besonders zweckmäßige Lösung sieht vor, daß das Einstellteil in den Innenraum einsetzbar ist und somit raumsparend in den erfindungsgemäßen Kältemittelkompressor integriert ist.A particularly useful in terms of compact design Solution provides that the adjustment part in the interior can be used and thus saves space in the inventive Refrigerant compressor is integrated.

Um ferner noch gleichzeitig eine Filterung des Sauggases zu erreichen, ist vorzugsweise vorgesehen, daß das Einstellteil ein Sauggasfilter aufnimmt.To further filter the suction gas at the same time achieve, it is preferably provided that the adjusting part absorbs a suction gas filter.

Das Einstellteil läßt sich beliebig einfach dann realisieren, wenn dieses einen Abdeckkörper aufweist, mit welchem entweder der Kühlkanalanschluß oder der Ansauganschluß verschließbar ist, so daß das über den Sauggasanschluß zugeführte Sauggas in den jeweils nicht verschlossenen Anschluß eintritt.The setting part can be implemented as simply as desired, if this has a cover body with which either the cooling duct connection or the suction connection can be closed is, so that the suction gas supplied via the suction gas connection enters the connection that is not closed.

Der Abdeckkörper könnte beliebig komplex ausgebildet sein. Eine besonders vorteilhafte Lösung sieht vor, daß der Abdeckkörper eine ungefähr halbzylindrische Form aufweist, so daß sich mit diesem in einfacher Weise der Kühlkanalanschluß oder der Ansauganschluß abdecken läßt, wenn diese in eine zylindrische Wand des Innenraums münden.The cover body could be of any complexity. A particularly advantageous solution provides that the cover body has an approximately semi-cylindrical shape, so that yourself with this in a simple manner the cooling duct connection or the suction port can be covered if this in a cylindrical wall of the interior open.

Um das Einstellteil in der jeweiligen Stellung an der Anschlußeinheit fixieren zu können, ist vorzugsweise vorgesehen, daß an dem Einstellteil eine Flanschplatte angeordnet ist, welche auf einen Anschlußflansch der Anschlußeinheit auflegbar ist, so daß mit dieser Platte einerseits eine Fixierung des Einstellteils erfolgt und andererseits dann an der Flanschplatte selbst die für die Zufuhr des Sauggases erforderlichen Elemente angeschlossen werden könnten.To the adjustment part in the respective position on the To be able to fix the connection unit is preferably provided that a flange plate is arranged on the adjusting part which is on a connection flange of the connection unit can be placed so that on the one hand with this plate Fixing of the setting part is done and then on the flange plate itself for the supply of the suction gas necessary elements could be connected.

Besonders vorteilhaft ist es in diesem Fall, wenn auf der Flanschplatte des Einstellteils das Sauggasabsperrventil montierbar ist.In this case, it is particularly advantageous if on the Flange plate of the setting part the suction gas shut-off valve is mountable.

Um gleichzeitig an der Flanschplatte erkennen zu können, in welcher Stellung das Einstellteil steht, ist vorzugsweise vorgesehen, daß die Flanschplatte auf einer Seite des Einstellteils eine andere Form aufweist, als auf einer gegenüberliegenden Seite. Damit ist bereits an der sich unterscheidenden Form der jeweils einander gegenüberliegenden Seiten in einfacher Weise die Stellung der Flanschplatte und somit die Stellung des Einstellteils erkennbar.In order to be able to recognize at the same time on the flange plate, in the position of the adjustment part is preferred provided that the flange plate on one side of the adjustment part has a different shape than on an opposite one Page. This is already the most different Shape of the opposite one another Pages in a simple manner the position of the flange plate and thus the position of the adjustment part is recognizable.

Besonders günstig ist eine Lösung, bei welcher die Flanschplatte und das fest an dieser angeordnete Einstellteil in zwei jeweils um 180° gegeneinander gedrehten Stellungen an der Aufnahme montierbar sind. Mit dieser Lösung lassen sich mit Standardflanschbefestigungen, welche eine zweizählige Symmetrie aufweisen, in einfacher Weise die beiden Stellungen des Einstellteils realisieren, ohne daß weitere besondere Befestigungsmaßnahmen erforderlich sind.A solution in which the Flange plate and the adjustment part firmly attached to it in two positions each rotated by 180 ° the mount can be mounted. With this solution you can with standard flange mountings, which are two-fold Have symmetry, the two positions in a simple manner of the setting part, without further special Fastening measures are required.

Die Zufuhr von Kältemittel erfolgt über ein Sauggasrohr 28, welches zu einem Sauggasabsperrventil 30 geführt ist. Das Sauggasabsperrventil 30 ist an einer als Ganzes mit 32 bezeichneten Anschlußeinheit montiert, welche über einen Kühlkanalanschluß 34 mit einem Kühlkanal 36 in Verbindung steht, der im Abschnitt 18 des Kompressorgehäuses 16 vorgesehen ist und dazu dient, angesaugtes Kältemittel durch einen den Motor 20 aufnehmenden Motorraum 38 und somit auch durch den Motor 20 hindurchzuführen, wobei der Kühlkanal 36 das angesaugte Kältemittel nach Durchströmen des Motors 20 zu einem Kühlkanalauslaß 40 führt.The refrigerant is supplied via a suction gas pipe 28, which is led to a suction gas shut-off valve 30. The Suction gas shut-off valve 30 is at 32 as a whole designated connector mounted, which over a Cooling channel connection 34 with a cooling channel 36 in connection is provided in section 18 of the compressor housing 16 is and serves to draw in refrigerant through a the engine compartment 38 accommodating the engine 20 and thus also through to pass the engine 20, the cooling channel 36 the drawn in refrigerant after flowing through the engine 20 a cooling channel outlet 40 leads.

Wie in Fig. 2 und 3 vergrößert dargestellt, sind der Kühlkanal 36 und der Ansaugkanal 46 durch eine im Kompressorgehäuse 16 vorgesehene Wand 60 getrennt und im Anschluß an die Wand 60 durch eine äußere Gehäusewand 62 und eine im Abstand von dieser verlaufenden innere Gehäusewand 64 begrenzt. Die Wand 60 verläuft dabei bis zu der Anschlußeinheit 32 und ist zur Bildung einer Aufnahme 66 mit einer Aussparung versehen, so daß die Aufnahme 66 einen Innenraum 68 bilden kann, welcher sich zwischen der äußeren Gehausewand 62 und der inneren Gehäusewand 64 erstreckt und in welchen der Kühlkanalanschluß 34 und der Ansauganschluß 44 einmünden.As shown in Fig. 2 and 3 enlarged, are the cooling channel 36 and the intake duct 46 through one in the compressor housing 16 provided wall 60 separately and following the wall 60 through an outer housing wall 62 and an in Distance from this inner housing wall 64 limited. The wall 60 extends up to the connection unit 32 and is to form a receptacle 66 with a Provide recess so that the receptacle 66 an interior 68 can form, which is between the outer housing wall 62 and the inner housing wall 64 extends and in which the cooling duct connection 34 and the suction connection 44 open.

In den Innenraum 68 der Aufnahme 66 ist ein als Ganzes mit 70 bezeichnetes Einstellteil über eine äußere Öffnung 71 einsetzbar, welches, wie in Fig. 4 und 5 dargestellt, einen mit seiner äußeren Mantelfläche zu einer Zylinderachse 72 ungefähr halbzylindrisch ausgebildeten Abdeckkörper 74 aufweist, welcher seinerseits fest mit einer Flanschplatte 76 verbunden ist.In the interior 68 of the receptacle 66 there is a whole with 70 designated adjustment part can be used via an outer opening 71, which, as shown in Fig. 4 and 5, one with its outer surface to a cylinder axis 72 approximately has semi-cylindrical cover body 74, which in turn is firmly connected to a flange plate 76 is.

Der ungefähr halbzylindrisch zur Achse 72 ausgebildete Abdeckkörper 74 ist dabei so in die Aufnahme 66 einsetzbar, daß sich die Zylinderachse 72 quer, vorzugsweise senkrecht zur äußeren Gehäusewand 62 und inneren Gehäusewand 64 erstreckt, wobei der Abdeckkörper 74 in Richtung der Zylinderachse 72 eine Länge aufweist, so daß er mit seiner der Flanschplatte 76 abgewandten Unterseite 78 im in die Aufnahme 66 eingesetzten Zustand bis zur inneren Gehäusewand 64 reicht, und vorzugsweise mit dieser abschließt.The approximately semi-cylindrical to the axis 72 Cover body 74 can be inserted into receptacle 66 that the cylinder axis 72 is transverse, preferably vertical to the outer housing wall 62 and inner housing wall 64 extends, with the cover body 74 in the direction of Cylinder axis 72 has a length so that it with his the bottom plate 78 facing away from the flange plate 76 in the Recording 66 inserted condition up to the inner housing wall 64 is sufficient, and preferably ends with this.

Der Abdeckkörper 74 umschließt in Form eines Zylindermantels einen Einströmraum 82 und weist ferner aufgrund seiner nur ungefähr halbzylindrischen Form noch eine Öffnung 80 auf, über welche Sauggas aus dem vom Abdeckkörper 74 umschlossenen Einströmraum 82 austreten kann. The cover body 74 encloses in the form of a cylinder jacket an inflow space 82 and further points because of it only approximately semi-cylindrical shape still has an opening 80, via which suction gas from that enclosed by the cover body 74 Inflow space 82 can emerge.

Die Flanschplatte 76 weist ferner eine Einströmöffnung 84 auf, welche einen Sauggasanschluß darstellt, über welchen vom Sauggasabsperrventil 30 in Richtung der Zylinderachse 72 Sauggas in den Einströmraum 82 einströmen kann.The flange plate 76 also has an inflow opening 84 on, which represents a suction gas connection, via which the Suction gas shut-off valve 30 in the direction of the cylinder axis 72 Suction gas can flow into the inflow space 82.

Vorzugsweise ist in den vom Abdeckkörper 74 umschlossenen Einströmraum 82 ein Sauggasfilter 86 einsetzbar, und zwar so, daß das von dem Sauggasabsperrventil 30 über die Einströmöffnung 84 zuströmende Sauggas zunächst das Sauggasfilter 86 durchsetzt und dann in den Einströmraum 82 eintritt.Preferably, the one enclosed by the cover body 74 Inflow space 82 a suction gas filter 86 can be used, specifically in such a way that of the Sauggasabsperrventil 30 via the inflow opening 84 incoming suction gas first the suction gas filter 86 penetrates and then enters the inflow space 82.

Der Abdeckkörper 74 mit der Flanschplatte 76 ist, wie in Fig. 2 und 3 dargestellt, entweder so in die Aufnahme einsetzbar, daß der Abdeckkörper 74 den Kühlkanalanschluß 34 im wesentlichen abdeckt und somit verhindert, daß das Sauggas von dem Einströmraum 82 in den Kühlkanal 36 eintritt, jedoch die Öffnung 80 dem Ansauganschluß 44 zugewandt ist, so daß das Sauggas von dem Einströmraum 82 über den Ansauganschluß 44 in den Ansaugkanal 46 eintreten kann, wie dies in Fig. 2 dargestellt ist.The cover body 74 with the flange plate 76 is, as in FIG. 2 and 3 shown, can either be inserted into the receptacle, that the cover body 74, the cooling duct connection 34 essentially covers and thus prevents the suction gas from the Inflow space 82 enters the cooling channel 36, but the Opening 80 faces the suction port 44, so that the Suction gas from the inflow space 82 via the intake port 44 in the intake duct 46 can enter, as shown in FIG. 2 is.

Es ist aber auch möglich, den Abdeckkörper 74 mit der Flanschplatte 76 um die die Zylinderachse 72 des Abdeckkörpers um 180° gedreht in die Aufnahme 66 einzusetzen, so daß der Abdeckkörper 74 den Ansauganschluß 44 abdeckt und verhindert, das Sauggas von dem Einströmraum 82 in den Ansaugkanal 46 eintreten kann. Das Sauggas strömt dann über die dem Kühlkanalanschluß 34 zugewandte Öffnung 80 über den Kühlkanalanschluß 34 in den Kühlkanal 36 ein, durchströmt, wie in Fig. 1 dargestellt, den Motorraum 38 und tritt über den Kühlkanalauslaß 40 in den Ansaugkanal 46 ein. But it is also possible to cover 74 with the Flange plate 76 around the cylinder axis 72 of the cover body to be rotated by 180 ° into the holder 66, see above that the cover body 74 covers the suction port 44 and prevents the suction gas from the inflow space 82 in the Intake channel 46 can occur. The suction gas then overflows the opening 80 facing the cooling duct connection 34 via the A cooling duct connection 34 flows into the cooling duct 36, As shown in Fig. 1, the engine compartment 38 and passes over the cooling duct outlet 40 into the intake duct 46.

Es ist aber auch möglich, den Abdeckkörper 74 so auszubilden, daß dieser den Kühlkanalanschluß 34 oder den Ansauganschluß 44 nur teilweise abdeckt, so daß stets ein gewisser Anteil des Sauggases in diesen eintritt, jedoch der größere Anteil des Sauggases in den Ansauganschluß 44 bzw. den Kühlkanalanschluß 34 eintritt. Ferner ist es noch möglich, Zwischenstellungen des Abdeckkörpers 74 vorzusehen, in welchen dieser teilweise den Ansauganschluß 44 und den Kühlkanalanschluß 34 abdeckt, so daß auch noch die in den Ansauganschluß 44 und den Kühlkanalanschluß 34 eintretenden Anteile des Sauggases in Zwischenstufen einstellbar sind.However, it is also possible to design the cover body 74 in such a way that that this the cooling duct connection 34 or the suction connection 44 only partially covers, so that always a certain proportion of the suction gas enters it, but the larger proportion of the suction gas into the intake port 44 or the cooling channel port 34 occurs. It is also possible to have intermediate positions to provide the cover body 74, in which this partially the intake port 44 and the cooling channel port 34 covers, so that also in the intake port 44 and portions of the suction gas entering the cooling duct connection 34 are adjustable in intermediate stages.

Zur Fixierung des Abdeckkörpers 74 mit der Flanschplatte 76 ist die Flanschplatte 76 mit zwei Schraubenlöchern 88, 90 versehen, die bezüglich der Zylinderachse 72 gegenüberliegend angeordnet sind, so daß die Flanschplatte 76 in zwei um 180° um die Zylinderachse 72 gedrehten Stellungen mit der äußeren Gehäusewand 62 verbindbar ist.For fixing the cover body 74 with the flange plate 76 is the flange plate 76 with two screw holes 88, 90 provided with respect to the cylinder axis 72 opposite are arranged so that the flange plate 76 in two by 180 ° positions rotated about the cylinder axis 72 with the outer Housing wall 62 is connectable.

Die Flanschplatte 76 stellt gleichzeitig auch einen Anschlußflansch für das Sauggasabsperrventil 30 dar, welches mit seinem Anschlußflansch auf die Flanschplatte 76 auflegbar ist und mit diesem gemeinsam mit einem Anschlußflansch 92 der Anschlußeinheit 52 mittels Schrauben verbindbar ist.The flange plate 76 also provides a connecting flange for the suction gas shut-off valve 30, which with its connecting flange can be placed on the flange plate 76 and with this together with a connecting flange 92 Connection unit 52 can be connected by means of screws.

Die Flanschplatte 76 ist bezüglich der Zylinderachse 72 asymmetrisch ausgebildet und weist beispielsweise auf seiten der Öffnung 80 zusätzliche Nasen 94 auf, die auf der gegenüberliegenden Seite, das heißt auf der geschlossenen Seite des Abdeckkörpers 74 nicht vorhanden sind, so daß an diesen Nasen 94 erkennbar ist, in welcher der beiden um 180° gegeneinander um 180° um die Zylinderachse 72 gedrehten Stellungen der Abdeckkörper 74 mit der Flanschplatte 76 eingesetzt ist.The flange plate 76 is with respect to the cylinder axis 72 designed asymmetrically and points to sides, for example opening 80 additional lugs 94 on the opposite Side, that is, on the closed side of the cover body 74 are not present, so that this Lugs 94 can be seen in which of the two by 180 ° against each other positions rotated by 180 ° around the cylinder axis 72 the cover body 74 is inserted with the flange plate 76.
