Abstract

A sliding-vane pump, which may be a vacuum pump, has a rotor (5) provided with a vane(s) (9) and rotates about an axis (16) in a housing bore. The or each vane has an extension (15) located on the other side of the axis (16). When the required positive or negative delivery pressure has been attained the vane(s) (9) is withdrawn from the bore wall (6) by a surface (28) of an element (27) movable transversely of the axis (16) by e.g. a rod (19) connected to a delivery- pressure controlled actuating unit, Fig. 1 (not shown). The pump is thereby rendered inoperative. The centre of gravity of each vane is situated such that it moves to the other side of the axis (16) when the vane is withdrawn from the bore wall. <IMAGE>
