Abstract

The pump has a rotor arranged in a pump chamber, and a venting area (7) upstream to the pump chamber. The venting area is connected with the pump chamber via a suction hole (6). A separating wall (14) separates a flow channel (13) from the venting area, and the flow channel arcuately surrounds the suction hole at a distance, where fluid delivers gas bubbles i.e. air bubbles, in the venting area and the flow channel. The flow channel has a concave region (14a) defined at an inlet opening (12) of an intake port (11) and comprising cross-section larger than that in an adjacent channel region.
