Into each of said bores, dowels (39, 39') are inserted with press fit. A central offset can be positively compensated by selecting the diameter of one of the dowels to be correspondingly larger than that of the associated dowel bore.

Rotary sliding-vane compressor

A vane-type compressor especially adapted for compressing refrigerant in air-conditioning systems has a vane carrying rotor mounted on fixed center bearings and surrounded by an eccentrically positioned cylinder guiding the vane motion and confining and controlling the compression process which is free to swing toward the rotor and maintain a line of tangency contact therewith providing a direct barrier between the discharge and suction sides of the compression chamber. A spring loaded end plate pressed against one end of the cylinder serves as a relief valve to purge liquid such as lubricant which might collect in the compression cavities during a shut-down period and which could otherwise create a lock-up condition. A fixed front bearing plate or end head has a cup-shaped housing piloted thereon surrounding the cylinder and providing a rear bearing mounting for the rotor. The front plate has an inlet port supplying the compression cavities between the rotor and cylinder. The cylinder has an outlet adjacent the tangency seal line of contact between the rotor and cylinder which discharges to a chamber between the housing and cylinder that is surrounded by porous fibrous strips effective to separate lubricant entrained in the compressed refrigerant. The refrigerant is discharged to an outlet port in the front bearing plate and the separated lubricant collects in the bottom of the housing and is circulated back to the bearings and vane slots of the rotor.

Hermetic compressor

본 발명은 토크 변동에 의한 회전방향 진동을 저감하는 밀폐형 압축기를 제공하는 것이다. 그 밀폐형 압축기는 외곽에 설치된 추를 구비한다. 추의 관성 모멘트를 증가함으로써, 전체 운전 주파수에 대해서 압축기의 회전방향 진동을 저감한다. The present invention is to provide a hermetic compressor which reduces the rotational vibration caused by the torque fluctuation. The hermetic compressor has a weight installed on the outside thereof. By increasing the moment of inertia of the weight, vibration in the rotational direction of the compressor is reduced over the entire operating frequency.
