Adjustable vacuum pump i.e. vane type pump, for gasoline engine of e.g. passenger car, has rotatably mounted rotor with blade that is movably supported in rotor, and adjusting device adjusting stator relative to rotor

摘要

The pump has a rotatably mounted rotor (1) with a blade (2) that is movably supported in the rotor. A stator (4) surrounds the rotor and sealingly contacts with end of the blade at an active surface (4a) that faces the rotor. An adjusting device adjusts the stator relative to the rotor, and a pump housing (6) has a housing body (6a) and a cover (6b), which surrounds the rotor, stator and the adjusting device. The blade has a sliding block or a sealing element at an end, and the stator (4) and a front face are formed in one piece.
