<p>A rotary pump is provided with a pump housing, a rotor (4) situated in the pump housing and rotatable by means of a drive shaft (5), and also blade elements (7) which are accommodated so that they can slide in grooves on the periphery of the rotor, and which interact in a sealing manner with a fixed cam surface (2). The pump housing is composed of three pump housing parts (1,8,9) tightly connected to each other, the central pump housing part containing the cam surface. In order to simplify the housing, a port plate (16) is provided with supply ports and discharge ports and accommodated in the central pump housing part (1). Preferably, the blade elements rest with one of their sides faces against an end face which is formed by the inward-facing surface of an outer pump housing part (8). <IMAGE></p> |
