Abstract

PURPOSE: To minimize oil pump capacity as well as to facilitate reduction of oil infusing amount into a compressor body by dewinding thrust engendered in the direction of intake side from discharge side.
CONSTITUTION: A rotor 20 in free command of swiveling in a rotor chamber 25 is supported by bearings 21W23, a hydraulic piston 26 is housed in free command of slinding in a cylinder chamber 24 installed adjacent to said rotor chamber 25. And a rotor axle 30 is protruded in the cylinder chamber 24, whose extremity is provided with a thrust bearing 29, the outer ring of the bearing 29 is prevented from swiveling in such a way that said piston 26 is constantly in contact with the extremity side of this bearing 29 by a spring 33. Further, the rotor chamber side and counter-rotor chamber side of the cylinder chamber are constituted to be conducted through bypass passages 37, 38 equipped with a valve 36. Said valve 36 opens when pressure difference grows to be more than a settled value at the both extremities of the piston 26, to prevent counter-thrust force F4 from being excessive.
