Definitions
- the invention relates to a pump for conveying a fluid, in particular a vane pump, with a housed in a housing conveyor, a formed in the housing supply channel for the fluid, which is in the intake the conveyor extends and upstream in one of the conveyor Blasting chamber opens, and with an injector, which is used to convey the fluid serves, radiates with a jet nozzle in the blasting chamber while under high Pressurized, fluid in the emerging from the feed channel in the blasting chamber Injecting fluid and thereby entrained or accelerated, wherein the blasting chamber via a suction channel with at least two suction kidneys of the conveyor fluidly connected.
- Pumps of the generic type are used for example in power steering systems and promote a special oil to support the steering wheel of a To cause motor vehicle applied steering force.
- these are vane pumps, which are provided from outside the pump Reservoir, for example, from an external tank, suck in oil.
- Such Pumps are usually equipped with a flow control valve, over the oil off the high pressure area - pressure side - in the intake - suction side - the Pump can be routed. From a certain pump speed and at a fixed flow rate, the flow control valve opens a discharge hole, can escape through the high pressure oil. The oil gets into the Intake area of the conveyor.
- valve piston under possibly high pressure on Valve piston at high speed in the jet nozzle flowing valve jet basically runs obliquely and therefore unsuitable symmetrically formed channels are.
- the present invention is therefore based on the object, a pump of the generic type Design and develop such a way that cavitations and thus occurring in the pump noise largely by simple design means are avoided.

Also in this respect could already previously referred to as the impact area Einström Anlagen or the ski-like guide first a for bundling the flow serving cross-sectional taper of the flow path be downstream, with the flow cross-section to the first Saugniere out steadily, swinging or even reducing in stages. The bundling of the flow leads to an acceleration of the fluid up to the first Saugniere.
- the flow cross-section between the first suction kidney and the second suction kidney at least equal to the flow area in front of the first suckling kidney. It should be ensured that the flow rates in the two Suck suckers into it at least largely evenly, so that a uniform loading of the suction kidneys takes place. Behind the second suction kidney could be formed a deflection causing baffle, so that thereby a deflection and thus a repeated BdinLINung the volume flow takes place into the second suction kidney.
- the suction channel could be immediate behind the second Saugnjere end with the deflection wall provided there.
- the suction channel in the area between the two suckers or after the rearmost in the flow direction suction kidney the blasting chamber or with the region of the suction channel in front of the first suction kidney be fluidly connected directly or via a bypass.
- Flow connection can be the pressure conditions and thus the flow rates affect before the respective suckling, so that in so far a Adjustment can take place with respect to the volume flows.
- the flow of the fluid in particular in the suction kidneys directed volumetric flow, through more far-reaching measures, namely by a modification of the inner wall of the blasting chamber and / or of the suction channel or the suction channels.
- the surfaces could affect the flow Have structures and / or coatings.
- the Inner walls - depending on requirements - be surface treated, with a roughening the surface to an increase of the flow resistance and a smoothing or smooth coating of the surface to a reduction of the flow resistance and thus leads to an acceleration of the flow.
