Abstract

PURPOSE:To prevent a seisure by providing oil feed grooves on a rear side plate at a position corresponding to the vicinity of a high pressure region of a compression chamber and on a front side plate at a position corresponding to the vicinity of a low pressure region of the compression chamber and by introducing the oil in an oil reservoir so as to properly feed it to the rotor terminal face. CONSTITUTION:While a compressor is in operation, gaps between a rotor 14 terminal face and both front and rear side plates 2, 3 are made smaller at the front side and larger at the rear side, but on the other hand, the chamber pressure of a compression chamber 17 near oil feed grooves 29, 30 serving for lubrication to the rotor 14 terminal face is a suction pressure at the front side and an discharge pressure at the rear side, therefore, the oil leakage from both oil feed grooves 29, 30 at the front side and at the rear side to the compression chamber 17 is restricted due to such a relation between gaps and pressures. Eventually, the quantity of oil feed to the rotor 14 terminal face from the oil feed grooves 29, 30 can be properly controlled resulting in satisfactory lubrication neither too much nor too less, a seizure can be prevented, and the volume efficiency can be also improved.
