Definitions
- the invention relates to a vane cell pump for conveying pressure oil from a container to a consumer.
- a pump package consisting of a rotor, several working slides and a cam ring is used in an interior of a pot-shaped housing cover of the wing cell pump.
- Working chambers are formed between the cam ring and the rotor by the working slides and are delimited in the axial direction by control plates.
- On the one side of the pot-shaped housing cover there is a storage housing that contains suction and pressure channels that connect the working chambers with the suction connection, a flow control valve and a pressure relief valve.
