摘要

The oscillating pump (1) has a housing (2) and disc (4) therein with a ring chamber (6) formed radially between same to contain a dividing element (7) which forms circumferential chambers (8). The housing or disc can be set secured against rotation about its own axis into oscillating movement through an eccentric drive so that the volume of the chambers can be varied which are dedicated to the suction side or pressure side of the pump. The pressure side of the pump has several pressure branches. The same or different delivery amounts can be supplied to the pressure branches.
