能ポンプ。 A rotor is rotatably housed in a pump housing consisting of a center housing with a hollow hole and a pair of side housings placed on both sides of the center housing, and multiple vanes are slid radially around the circumference of the rotor. an expansion pump chamber which is movably provided and whose vane divides a crescent-shaped space formed between the pump housing and the rotor into a plurality of pump chambers on the circumference, the volume of which increases as the rotor rotates; A vacuum suction port is opened at the starting end of the expansion pump chamber, a compressor suction port is opened at the terminal end of the expansion pump chamber, and a compressor discharge port is opened at the terminal end of the contraction pump chamber whose volume decreases due to rotation of the rotor. In the functional pump, a side plate is held by the side housing, is in contact with an end surface of the center housing by an elastic member, and is movable in the axial direction in response to pressure on a side surface of the rotor due to thermal expansion in the axial direction of the rotor. A multi-functional pump characterized by:
