Description
The present invention relates to the compressor of a kind of exhaust turbine supercharger of preamble according to claim 1.
In this genus class compressor that is equipped with a hypervelocity air re-circulation valve, this compressor housing has an inflow catheter, and this inflow catheter extends to the suction port of compressor from compressor outlet.Described inflow catheter is controlled by this hypervelocity air re-circulation valve, so that the operation period at exhaust turbine supercharger prevents pumping effect, pumping effect for example may occur in because this throttling flap of braking process of motor vehicle is closed when this exhaust turbine supercharger is still with high rotating speed operation.In this case, in order to prevent described effect, this hypervelocity air re-circulation valve is opened, and air on the pressure side is directed to the suction port of compressor from this compressor outlet or this, does not have significant pressure to gather in order to guarantee to pass the Continuous Flow of this compressor impeller.
In known design, this inflow catheter radially extends in this suction port of compressor, this means that this inflow is drawn towards the center of the axle of this exhaust turbine supercharger.
The test of carrying out about the known turbochargers of described design in the context of the present invention shows, this inflow catheter that causes owing to the inflow direction to this compressor impeller is with respect to the described opening radially of this axle, produced hydrodynamic noise, this hydrodynamic noise can cause undesirable noise interference the in service of vehicle of the exhaust turbine supercharger that is equipped with described type.
By contrast, an object of the present invention is to provide a kind of in the preamble of claim 1 compressor of specified type, this compressor makes it might avoid or reduce considerably the hydrodynamic noise of explanation, and suppresses the resonance of any generation.
Described purpose is that these features by claim 1 realize.
According to described claim, this inflow catheter is arranged at its mode in this compressor housing for leading to this suction port of compressor at the circumferencial direction with respect to the tubulose inner diameter of this tubular compression machine entrance at least.Described opening also can be called a substantial at least tangential opening, this tangential opening causes from the pressure side being recycled a tangential inflow or a tangential inflow of pointing to circumferencial direction of the air that becomes air amount, this inflow does not have substantially destructive influences to this compressor impeller at least, and the hydrodynamic noise that therefore illustrates to major general's preamble reduces to a kind of like this degree so that these noises in fact no longer are realizable.
Flow into loss in order to reduce, the inflow of basically pointing to circumferencial direction also may have an axial component on this flow direction.
For this purpose, this suction port of compressor can be equipped with a cylindrical or Frusto-conical inflow section, and this inflow catheter is opened by above illustrated mode in this inflow section.
These dependent claims relate to a plurality of favourable improvement of the present invention.
In an especially preferred embodiment, this inflow catheter lead in this suction port of compressor mode so that the inflow of recirculated air guide in the sense of rotation of this compressor impeller.Yet with the inflow of the direction of rotation of this compressor impeller also be possible in principle.
From the explanation of following a plurality of exemplary based on accompanying drawing, will show further details of the present invention, advantage and feature, in the accompanying drawings:
Fig. 1 shows the perspective view that can be equipped with according to the Partial Resection of a kind of exhaust turbine supercharger of compressor of the present invention;
Fig. 2 and Fig. 3 show the first embodiment according to a kind of compressor of the present invention; And
Fig. 4 shows the second embodiment according to a kind of compressor of the present invention.
Fig. 1 has showed that this turbosupercharger has a turbine cylinder 2 according to a kind of exhaust turbine supercharger 1 of the present invention, and this turbine cylinder comprises an exhaust entrance opening 3 and an exhaust outlet opening 4.
In addition, a turbine wheel 5 is arranged in this turbine cylinder 2, and this turbine wheel is secured on the axle 6.
A plurality of blades (only showing blade 7 wherein) are arranged in turbine cylinder 2 between this exhaust entrance opening 3 and this turbine wheel 5.
In addition, this exhaust turbine supercharger 1 has a compressor 8, and the compressor housing 10 of this compressor is connected on this turbine cylinder 2 via a bearing housing 9 in common mode.In compressor housing 10, a compressor impeller 11 is fastened on the second end of this axle 6.Details according to compressor 8 of the present invention will describe based on Fig. 2 to Fig. 4 hereinafter, and these details have been showed two embodiments according to compressor 8 of the present invention, and these two schemes can be used in the exhaust turbine supercharger 1 that Fig. 1 shows.
Embodiment according to Fig. 2 and Fig. 3 clearly show that this compressor impeller in Fig. 2, together with label " sense of rotation VR ", this label uses the sense of rotation related with it to represent this compressor impeller 11 by three drafting arrow VR.Compressor impeller 11 is shown in Figure 3 and be arranged on this axle 6.
In Fig. 2, the inflow catheter of this hypervelocity air re-circulation valve (invisible in these figure) is with reference number 14 indications, and wherein said inflow catheter 14 roughly (is seen Fig. 4, D in a circumferential direction or with respect to this inner diameter along these two dotted lines
I) tangentially open.Here, Fig. 3 clearly show that an inflow catheter opening 16, and this inflow catheter opening leads to the mode in the funnel entrance 12 of a tubulose or funnel-like or frusto-conical so that allow from the tangential inflow of the air of these compressor outlet 13 recirculation.As what be clearly shown that among Fig. 2 and Fig. 3, the inflow is here carried out with the direction opposite with sense of rotation VR.
Illustrate in addition in Fig. 2 and parallel dot and dash line that represented by reference symbol ZK only is used for being clearly shown that the arrangement according to the inflow catheter of prior art.Described illustrated dotted line ZK clearly show that with respect to axle 6 inflow catheter arrangement radially, and this is relevant with the problem that illustrates in the preamble.Here again mention, the described extra drawing of known inflow catheter ZK among Fig. 2 only is used for being clearly shown that the difference between prior art and the present invention, such inflow catheter ZK be not provided at according in the embodiment of Fig. 2 and Fig. 3 or in according to the embodiment of Fig. 4 according in the compressor of the present invention.
