    摘要： The disclosed rolling piston type compressor comprises a needle bearing sandwiched between two bearing washers and serving as a thrust bearing for a rotary shaft and a resilient sealing ring of polytetrafluoroethylene press fitted into a space defined by the outer periphery of the needle bearing and the two bearing washers. Alternatively the sealing ring may be formed of cast iron and seal the space with an oil film disposed in a clearance between the ring and one of the bearing washers.

    摘要： A rotary compressor having a piston provided integrally with a blade is contained in a hermetic vessel which is operated at a suction pressure of the rotary compressor and not to discharge pressure. The rotary compressor includes a compression mechanism portion having a cylinder which includes a suction port formed in a cylinder chamber, a piston which eccentrically revolves in the cylinder, a blade which is integrally formed with the piston and partitions the cylinder chamber into a high pressure chamber and a low pressure chamber, and a driving shaft for revolving the piston. The rotary compressor also includes an electric motor portion for rotating the driving shaft, a hermetic vessel which houses the compression mechanism portion and the electric motor portion and is in communication with the suction port thereby to maintain an interior of the hermetic vessel at a suction pressure atmosphere, and a discharge port formed in the cylinder chamber and in direct communication with an exterior of the hermetic vessel, whereby starting is smoothly performed, a motor having a large starting torque is not required, components such check valves can be avoided, and lubricating oils with stable viscosity can be used such that the compressor operates with environmentally-friendly refrigerants.

    摘要： An eccentric part of a crank shaft rotated in a cylinder is made a large diameter and a thin-walled rolling piston is fitted to the outer circumference of the eccentric part so that an injection opening for supplying a refrigerant into the cylinder is covered in a certain section by only a side surface of the eccentric part or both the side surfaces of the rolling piston and the eccentric part.
