摘要： A piston type compressor is disclosed, which includes pistons disposed in bores of a cylinder block, to be reciprocated by a piston driving mechanism in cooperation with a drive shaft. A valve receiving chamber is formed around the drive shaft in the cylinder block, for receiving a rotary valve to rotate together with the drive shaft. The rotary valve has a suction passage formed therein for providing gases from a gas suction chamber to a compression chamber defined in each bore. A plurality of communication passages are formed in the cylinder block in association with the compression chambers, to provide gas communication between the compression chambers and the valve's suction passage. A bypass passage is formed on the rotary valve, and permits one communication passage, associated with one of the compression chambers which is at a final stage of a compression stroke, to communicate with another communication passage, associated with another compression chamber which is at a start stage of the compression stroke. The compressor further includes a device, provided on an outer surface of each piston, for catching gas axially leaking along the outer surface of the piston. The gas catching device guides gas, caught by the gas catching device at the final stage of the compression stroke, to the communication passage corresponding to its associated compression chamber.

摘要： A piston type compressor has a plurality of cylinder bores in which a plurality of pistons reciprocate to effect suction, compression and discharge of refrigerant gas in response to rotation of a drive shaft. The compressor has a gas receiving chamber for receiving the refrigerant gas before compression, a discharge chamber for receiving the compressed gas, and at least one rotary valve mounted on the drive shaft to be rotatable with the drive shaft. The rotary valve has a suction passageway for providing fluid communication between the gas receiving chamber and each of the compression chambers formed in the cylinder bores. A groove is provided on the outer circumferential wall of the rotary valve. The groove is connected with the outlet of the suction passageway and extends to a vicinity of the opposing end portions along the outer circumferential wall. The groove supplies the lubricant oil within the refrigerant gas in the suction passageway to and between the outer circumferential wall of the rotary valve and the inner wall of the recessed chamber during the rotation of the rotary valve.

A valve receiving chamber is formed around the drive shaft in the cylinder block, for accommodating a rotary valve which rotates in synchronism with rotation of the drive shaft. The rotary valve has a suction passage formed therein for providing gases from the gas suction chamber to a compression chamber during the chamber's gas suction stroke. A plurality of gas communication passages are formed in the cylinder block in association with the compression chambers, each having a first port open to the associated cylinder bore and a second port open to the valve receiving chamber. The first port is located at a position (P2) apart by a predetermined distance (L) from a top dead center position (P1) of the associated piston. The rotary valve has a bypass passage formed therein, for permitting one communication passage, isolated from both the compression chambers and the gas suction chamber, to communicate with another communication passage corresponding to a compression chamber in a compression stroke.

摘要： A refrigerant gas suction valve mechanism for a reciprocating piston type compressor is disclosed. The mechanism has a drive shaft rotatably disposed in a gas receiving chamber where uncompressed gas is introduced, Double- headed pistons provided in cylinder bores compress the gas when the pistons move from the bottom dead center to the top dead center. A suction port selectively permits and blocks communication between the suction passage and the compression chambers. A resilient member holds a rotary valve in contact with an inner wall of a recessed chamber with predetermined force. The suction port is maintained at a predetermined distance from a point where the pistons reach the top dead center so that the suction port is closed by the pistons before the pistons reach the top dead center.

摘要： A compressor comprises a cylinder block having cylinder bores formed radially spaced from and circumferentially distributed equidistantly about the cylinder longitudinal axis. Pistons are slidably received in the respective bores for reciprocation therein executing alternately suction and discharge strokes. The compressor also has a discharge valve assembly for controlling discharge of a compressed fluid from each of the bores into a discharge chamber, which assembly is axially movable between a first position in which the assembly is abutted against an end wall of the block and a second position in which the assembly is spaced from the end wall of the block to define a narrow space therebetween to interconnect the bores with each other. When the assembly is pushed toward the second position by the pressure of the compressed fluid during initial running of the compressor, bypass channels interconnect the cylinder with the discharge chamber.

摘要： A swash plate type compressor includes a cylinder blocks having a crank case which communicates with a suction port and a plurality of bores formed therein. The ends of each bore are covered with a pair of housings. The bores communicate with discharge chambers. A drive shaft is rotatably placed within the cylinder blocks. A swash plate is rotatable in the crank case, and is mounted on the drive shaft. A plurality of pistons are drivably coupled to the swash plate, and are reciprocotable in their respective bores. As the pistons reciprocate, a refrigerant in the crank case is sucked into each bore and is compressed therein. The compressed refrigerant is discharged into the discharge chambers from the bores. A passage for transporting the refrigerant between the discharge chambers is formed along the axis of the drive shaft. Seals are provided between the cylinder blocks and the drive shaft for sealing the gap between the discharge chambers and the crank case.
