ける給油装置。 A rotor is rotatably housed in a pump housing, and a plurality of vanes are provided on the circumference of the rotor so as to be slidable in the radial direction, and the vanes form a crescent shape between the pump housing and the rotor. The space is circumferentially divided into a plurality of pump chambers, a vacuum suction port is opened at the starting end of the expansion pump chamber whose volume increases with rotation of the rotor, and a compressor suction port is opened at the terminal end of the expansion pump chamber. In a multi-function pump in which a compressor discharge port is opened at the end of a contraction pump chamber whose volume decreases due to rotation of the rotor, lubricating oil is separated downstream of the compressor discharge port and the separated lubrication is performed. An oil separator is installed to pump oil using the compressor discharge pressure.
An oil supply device for a multi-function pump, characterized in that an oil supply port through which the lubricating oil is introduced opens into the contraction pump chamber.
