摘要： A rotary compressor is provided with a cylinder which defines a cylinder chamber and a piston disposed in the cylinder chamber. The piston includes a roller which performs a revolving motion within the cylinder chamber and a vane which partitions the interior of the cylinder chamber into a suction chamber and a compression chamber. A small space is provided so as to communicate with the compression chamber in only a predetermined section without communicating with the suction chamber so as to suppress noise generated by a pressure fluctuation in the interior of a compression chamber and, at the same time, can prevent the occurrence of a loss induced by re-expansion of a refrigerant remaining in a small space and a loss induced by return of the refrigerant to a suction chamber.

摘要： A closed type motor-driven compressor includes a motor accommodated in a closed container and a compression mechanism connected through a crank shaft to the motor. A shielding member having a cylindrical portion substantially concentric with the axis of the compression mechanism is disposed between the motor and the compression mechanism. This shielding member defines a shielding air space between the motor and the compression mechanism for preventing a permeation of a lubricating oil. An inlet of a discharge pipe of the closed type motor-driven compressor is positioned inwardly of this shielding air space.

摘要： In a compressor, a lubricant groove for a contact area between a self-aligning spherical bearing and a housing therefor opens to a relatively low pressure chamber, but is prevented from opening to a relatively high pressure chamber, the housing has an arrangement for restraining a transmission of deformation and/or heat energy from a welded portion thereon to the contact area, and a main shaft, the housing, a housing lid and a pipe for lubricant circulation are coaxially arranged.
