"POMPA OLIO A PALETTE A PORTATA VARIABILE" "VARIABLE FLOW VANEL OIL PUMP"

La presente innovazione è relativa ad una pompa olio a palette a portata variabile. The present innovation relates to a variable displacement vane oil pump.

In particolare, la presente innovazione è relativa ad una pompa olio a palette a portata variabile del tipo comprendente un rotore, il quale è montato per ruotare attorno ad un proprio asse longitudinale determinato, e presenta una pluralità di scanalature aperte radialmente verso l'esterno; uno statore, che si estende attorno al rotore, ed è montato eccentrico rispetto al rotore stesso; una pluralità di palette, ciascuna delle quali è montata scorrevole all'interno di una relativa scanalatura, e presenta un bordo esterno disposto sostanzialmente a contatto dello statore; e mezzi di regolazione per controllare selettivamente l'eccentricità tra il rotore e lo statore e, quindi, la portata della pompa. In particular, the present innovation relates to a variable displacement vane oil pump of the type comprising a rotor, which is mounted to rotate around its own determined longitudinal axis, and has a plurality of grooves open radially outwards; a stator, which extends around the rotor, and is mounted eccentric with respect to the rotor itself; a plurality of vanes, each of which is mounted slidably inside a relative groove, and has an outer edge arranged substantially in contact with the stator; and adjustment means for selectively controlling the eccentricity between the rotor and the stator and, therefore, the flow rate of the pump.

Le pompe olio a palette a portata variabile note del tipo sopra descritto presentano alcuni inconvenienti principalmente discendenti dal fatto di presentare un attrito di strisciamento relativamente elevato tra le palette e lo statore. Known variable displacement vane oil pumps of the type described above have some drawbacks mainly deriving from the fact that they have a relatively high sliding friction between the vanes and the stator.

Scopo della presente innovazione è di realizzare una pompa olio a palette a portata variabile che sia esente dagli inconvenienti sopra esposti. The object of the present invention is to provide a variable displacement vane oil pump which is free from the drawbacks described above.

Secondo la presente innovazione viene realizzata una pompa olio a palette a portata variabile secondo quanto rivendicato nelle rivendicazioni allegate. According to the present invention, a variable displacement vane oil pump is provided according to what is claimed in the attached claims.

La presente innovazione verrà ora descritta con riferimento ai disegni annessi, che ne illustrano un esempio di attuazione non limitativo, in cui: The present invention will now be described with reference to the attached drawings, which illustrate a non-limiting example of embodiment, in which:

la figura 1 è una sezione longitudinale schematica di una preferita forma di attuazione della pompa a palette della presente innovazione; Figure 1 is a schematic longitudinal section of a preferred embodiment of the vane pump of the present invention;

la figura 2 è una sezione secondo la linea II-II della figura 1; e Figure 2 is a section along the line II-II of Figure 1; And

la figura 3 è una sezione secondo la linea III-III della figura 1. Figure 3 is a section along the line III-III of Figure 1.

Con riferimento alle figure da 1 a 3, con 1 è indicata, nel suo complesso, una pompa a palette a portata variabile per l'alimentazione di olio ad un circuito di lubrificazione (non illustrato) di un motore a combustione interna (non illustrato) di un veicolo (non illustrato). With reference to Figures 1 to 3, 1 indicates, as a whole, a variable displacement vane pump for supplying oil to a lubrication circuit (not shown) of an internal combustion engine (not shown) of a vehicle (not shown).

La pompa 1 comprende una carcassa 2 di supporto, la quale ha una forma sostanzialmente parallelepipeda a sezione sostanzialmente rettangolare, e comprende, a sua volta, una prima piastra 3 limitata lateralmente da una superficie 4 sostanzialmente piana. La piastra 3 è provvista di una cavità 5, la quale presenta un asse 6 longitudinale ortogonale alla superficie 4, si apre verso l'esterno in corrispondenza della superficie 4, ed è chiusa assialmente da una seconda piastra 7 disposta a contatto della superficie 4 stessa. The pump 1 comprises a support casing 2, which has a substantially parallelepiped shape with a substantially rectangular section, and in turn comprises a first plate 3 laterally limited by a substantially flat surface 4. The plate 3 is provided with a cavity 5, which has a longitudinal axis 6 orthogonal to the surface 4, opens outwards at the surface 4, and is closed axially by a second plate 7 arranged in contact with the surface 4 itself. .

La pompa 1 comprende, inoltre, un albero 8 motorizzato, il quale è montato attraverso le piastre 3 e 7 per ruotare attorno all'asse 6, e porta calettato un rotore 9 cilindrico, che è alloggiato all'interno della cavità 5, e presenta una larghezza, misurata parallelamente all'asse 6, sostanzialmente pari alla larghezza della cavità 5 anch'essa misurata parallelamente all'asse 6. The pump 1 also comprises a motorized shaft 8, which is mounted through the plates 3 and 7 to rotate around the axis 6, and has a keyed cylindrical rotor 9, which is housed inside the cavity 5, and has a width, measured parallel to the axis 6, substantially equal to the width of the cavity 5 also measured parallel to the axis 6.

La cavità 5 alloggia, inoltre, al proprio interno uno statore 10, il quale si estende attorno al rotore 9, presenta una larghezza, misurata parallelamente all'asse 6, sostanzialmente pari alla larghezza della cavità 5 anch'essa misurata parallelamente all'asse 6, ed è limitato internamente da una superficie 11 sostanzialmente cilindrica disposta in posizione eccentrica rispetto al rotore 9. The cavity 5 also houses inside a stator 10, which extends around the rotor 9, has a width, measured parallel to the axis 6, substantially equal to the width of the cavity 5 also measured parallel to the axis 6 , and is internally limited by a substantially cylindrical surface 11 arranged in an eccentric position with respect to the rotor 9.

Lo statore 10 è incernierato alla piastra 3 per oscillare, rispetto alla piastra 3 stessa e sotto il controllo di un dispositivo 12 di regolazione di tipo noto, attorno ad un asse 13 di fulcro parallelo all'asse 6 e consentire, quindi, di controllare selettivamente l'eccentricità tra il rotore 9 e la superficie 11. The stator 10 is hinged to the plate 3 to oscillate, with respect to the plate 3 itself and under the control of an adjustment device 12 of a known type, around a fulcrum axis 13 parallel to the axis 6 and therefore allow to selectively control the eccentricity between the rotor 9 and the surface 11.

Il rotore 9 presenta due cavità 14 cilindriche fra loro opposte, le quali sono ricavate coassialmente all'asse 6, e sono affacciate una alla piastra 3 e l'altra alla piastra 7, ed è provvisto di una pluralità di scanalature 15 radiali (nella fattispecie sei scanalature 15), che sono ricavate attraverso il rotore 9 parallelamente all'asse 6, sono uniformemente distribuite attorno all'asse 6, si aprono radialmente verso l'esterno in corrispondenza di una superficie 16 esterna del rotore 9 coassiale all'asse 6, e si aprono, inoltre, assialmente verso l'esterno in corrispondenza delle cavità 14. The rotor 9 has two cylindrical cavities 14 opposite each other, which are formed coaxially to the axis 6, and face one to the plate 3 and the other to the plate 7, and is provided with a plurality of radial grooves 15 (in this case six grooves 15), which are obtained through the rotor 9 parallel to the axis 6, are uniformly distributed around the axis 6, open radially outwards at an external surface 16 of the rotor 9 coaxial to the axis 6, and also open axially outwards in correspondence with the cavities 14.

Ciascuna scanalatura 15 è impegnata in maniera scorrevole da una paletta 17 presentante un bordo 18 esterno, il quale si estende parallelamente all'asse 6, ed è disposto sostanzialmente a contatto della superficie 11 dello statore 10 tramite l'interposizione di un pattino 19 anulare. Each groove 15 is slidably engaged by a blade 17 having an outer edge 18, which extends parallel to the axis 6, and is arranged substantially in contact with the surface 11 of the stator 10 through the interposition of an annular shoe 19.

Il pattino 19 presenta una larghezza, misurata parallelamente all'asse 6, sostanzialmente pari alla larghezza di una paletta 17 anch'essa misurata parallelamente all'asse 6, ed è accoppiato in maniera circonferenzialmente scorrevole sia allo statore 10, sia alle palette 17. The shoe 19 has a width, measured parallel to the axis 6, substantially equal to the width of a blade 17 also measured parallel to the axis 6, and is coupled in a circumferentially sliding manner both to the stator 10 and to the blades 17.

Ciascuna paletta 17 sporge assialmente dalla relativa scanalatura 15 all'interno delle cavità 14, e presenta un bordo 20 interno, il quale si estende parallelamente all'asse 6, ed è disposto sostanzialmente a contatto di due elementi 21 anulari, ciascuno dei quali è alloggiato all'interno di una delle cavità 14, si estende attorno all'albero 8, e presenta un diametro maggiore del diametro dell'albero 8 e minore del diametro della relativa cavità 14 in modo da flottare all'interno della relativa cavità 14 stessa. Each blade 17 protrudes axially from the relative groove 15 inside the cavities 14, and has an internal edge 20, which extends parallel to the axis 6, and is arranged substantially in contact with two annular elements 21, each of which is housed inside one of the cavities 14, it extends around the shaft 8, and has a diameter greater than the diameter of the shaft 8 and smaller than the diameter of the relative cavity 14 so as to float inside the relative cavity 14 itself.

Ciascuna coppia di palette 17 fra loro adiacenti delimita circonferenzialmente una relativa camera 22 di pompaggio, la quale è limitata, inoltre, radialmente dal rotore 9 e dal pattino 19 ed assialmente dalle piastre 3 e 7, viene spostata dal rotore 9 attorno all'asse 6 ed attraverso un ingresso 23 di aspirazione ed una uscita 24 di mandata dell'olio, e presenta, a seguito della rotazione del rotore 9 attorno all'asse 6 e dell'eccentricità tra il rotore 9 e la superficie 11 dello statore 10, un volume variabile. Each pair of blades 17 adjacent to each other circumferentially delimits a relative pumping chamber 22, which is also limited radially by the rotor 9 and the shoe 19 and axially by the plates 3 and 7, is displaced by the rotor 9 around the axis 6 and through a suction inlet 23 and an oil delivery outlet 24, and has, following the rotation of the rotor 9 around the axis 6 and the eccentricity between the rotor 9 and the surface 11 of the stator 10, a volume variable.

A questo proposito è opportuno precisare, inoltre, che il volume di ciascuna camera 22 in corrispondenza dell'ingresso 23 e dell'uscita 24 e, quindi, la portata della pompa 1 vengono controllati selettivamente spostando lo statore 10 attorno all'asse 13 e modificando, quindi, l'eccentricità tra il rotore 9 e la superficie 11 dello statore 10 stesso. In this regard, it should also be noted that the volume of each chamber 22 at the inlet 23 and the outlet 24 and, therefore, the flow rate of the pump 1 are selectively controlled by moving the stator 10 around the axis 13 and modifying hence, the eccentricity between the rotor 9 and the surface 11 of the stator 10 itself.

Secondo quanto illustrato nella figura 2, ciascuna paletta 17 comprende una pluralità di lamine 25 (nella fattispecie quattro lamine 25), le quali sono sovrapposte fra loro, e sono accoppiate in maniera radialmente scorrevole l'una all'altra per garantire un accoppiamento a tenuta di fluido relativamente efficiente tra la paletta 17 ed il pattino 19. As shown in Figure 2, each blade 17 comprises a plurality of foils 25 (in this case four foils 25), which are superimposed on each other, and are coupled in a radially sliding manner to each other to ensure a tight fit. of relatively efficient fluid between the vane 17 and the shoe 19.

Secondo una variante non illustrata, il pattino 19 è alloggiato all'interno di una cavità anulare, la quale è ricavata nello statore 10, e si apre verso l'esterno in corrispondenza della superficie 11, e sporge all'esterno dalla cavità stessa per disporsi a contatto delle palette 17. According to a variant not illustrated, the shoe 19 is housed inside an annular cavity, which is formed in the stator 10, and opens outwards at the surface 11, and protrudes outwards from the cavity itself to arrange itself in contact with the vanes 17.

Il funzionamento della pompa 1 è facilmente desumibile da quanto sopra esposto e non necessita di ulteriori spiegazioni. The operation of the pump 1 can be easily deduced from the foregoing and does not require further explanations.
