Abstract: A swash plate type variable displacement compressor includes a collection and supply mechanism. The collection and supply mechanism has collection passages, supply passages, an annular space, an inlet port, and an outlet port. The inlet port is communicable with a working collection passage of the collection passages. The outlet port is communicable with a working supply passage of the supply passages. When the inclination angle of the swash plate is maximum, residual refrigerant gas in a compression chamber of collection phase is collected through the working collection passage and the collected refrigerant gas is supplied to a compression chamber of supply phase. On the other hand, when the inclination angle is less than the maximum, residual refrigerant gas is supplied no more into the supply-phase compression chamber.

Abstract: A compressor includes a valve base plate, which is arranged between a suction chamber and a compression chamber and has a suction port. The valve base plate includes a sealing surface, a recessed groove, a receiving surface, and a support surface. The sealing surface is flush with a fixing surface and contacts the valve portion in an annular manner. The recessed groove is located at an outer side of the sealing surface and recessed with respect to the fixing surface. The recessed groove includes a bottom portion and separates an edge portion of the valve portion from the bottom portion. The receiving surface is flush with the fixing surface and capable of contacting a distal zone of the valve portion. The support surface is flush with the fixing surface and capable of contacting a middle zone located at an inner side of the sealing surface of the valve portion.

Abstract: A variable displacement type swash plate compressor includes a housing having therein a suction chamber, a discharge chamber, a control pressure chamber, a shaft hole, and cylinder bores. The compressor further has a drive shaft, a swash plate, an inclination angle changing mechanism, pistons, introduction passages, and a valve mechanism. The valve mechanism includes a valve element is disposed in a passage connecting the control pressure chamber and the suction chamber. The valve element is integrally rotatable with the drive shaft and axially movable by a pressure difference across the valve element. An opening of the residual gas bypass passage is changed by the axial movement of the valve element. The valve element selectively connects and disconnects the introduction passages with the residual gas bypass passage.

Abstract: The present invention provides a variable displacement swash plate type compressor that reduces wear of cylinder bores and the amount of blow-by gas. Each piston of the compressor has a piston main body, which has a distal portion located at an end corresponding to the compression chamber. A tapering portion and an arcuate portion are formed in the distal portion. The arcuate portion is continuous with an end of the tapering portion that is closer to the compression chamber. The tapering portion and the arcuate portion each have a diameter that increases toward the skirt. The tapering portion has a tapering angle that is in a range from 0.45 degrees to 1.5 degrees. The distance between the distal end of the piston main body and a starting point of the tapering portion on an end closer to the skirt is set in a range from 1.5 mm to 5.0 mm.

Abstract: A piston-type compressor includes a housing, a drive shaft supported on the housing, a communication hole formed inside the drive shaft, a valve mechanism, and a cylindrical body. The cylindrical body is inserted in the communication hole to disconnect a residual gas bypass passage and the communication hole from each other and to open the interior space of the cylindrical body to the communication hole. The valve mechanism includes an annular space defined outside the cylindrical body in the communication hole and multiple connection holes providing communication between the annular space and communication passages. The residual gas bypass passage is formed of the annular space and the multiple connection holes.
