    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 compressor includes first and second cylinder blocks having cylinder bores and surrounding a drive shaft, and the bores of the first block are aligned and registered with the bores of the second block, respectively, the blocks being arranged to define a suction chamber therebetween. First and second housings are associated with the first and second blocks to define first and second discharge chambers therebetween, which are in communication with each other through a central passage of the drive shaft. Double-headed pistons are slidably received in the pairs of aligned bores, respectively, and a conversion mechanism is disposed within the suction chamber for converting a rotation of the shaft into a reciprocation of each piston in the corresponding aligned cylinder bores such that suction and compression strokes are alternately executed. A rotary valve introduces fluid into the bores just after the suction stroke is initiated, and the introduction of fluid is continued until the suction stroke is finished.

    摘要: A swash plate type compressor comprises a cylinder block cooperating to form therein a compartment accommodating therein a swash plate and also serving as a suction chamber of the compressor, and a drive shaft rotatably supported in the cylinder block and having formed therein an axial discharge passage connecting front and rear discharge chambers. The compressor further includes a pair of front and rear rotary type suction valves mounted on the drive shaft for rotation therewith and fitted in bores formed centrally in the cylinder block such that one axial end thereof is exposed to suction pressure and the other end to discharge pressure of the refrigerant gas. Each suction valve has formed therein a passage which is in constant communication with the swash plate compartment and is operable to bring its passage in communication successively with fluid working chambers in synchronism with the rotation of the drive shaft. The drive shaft is formed with a lubricating oil hole extending radially from its central discharge passage to its outer periphery and directed to feed lubricating oil toward the sliding contact surfaces between the suction valve and its accommodation bore.

    摘要: A swash plate type compressor comprising a swash plate accommodated in a swash plate chamber. Front and rear housings are attached to the cylinder block to form suction chambers and discharge chambers, respectively. A refrigerating medium is introduced from a suction inlet to the suction chambers via the swash plate chamber and discharged from the discharge chambers. A drive shaft is fixed to the swash plate for reciprocally moving pistons. The drive shaft has a discharge passage in the form of an axial bore formed in the drive shaft for connecting the front discharge chamber to the rear discharge chamber. The discharge passage is thus isolated from the suction system.

    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.

    摘要: The durability of a coating layer formed on the sliding surface between two members of a compressor, and the sliding contact between the two members, is kept excellent over a long period of time. In a peripheral portion 10d of a swash plate 10, a pair of shoes 20 are connected to the swash plate 10 while intervening between the swash plate 10 and a piston 8. Both the swash plate 10 and the shoes 20 are formed from an iron series material. A film 23 is formed on both surfaces 22 of the peripheral portion 10d of the swash plate 10, and the shoes 20 slide on the film 23 on the swash plate 10. The film 23 is a coating layer formed from a resin containing metallic particles. The particle size of the metallic particles is larger than the thickness of the film 23 (e.g., from 10 to 100 &mgr;m), and the surface of the film 23 is made smooth by polishing. The resin functioning as a binder of the metallic particles is formed from, for example, a polyimide resin.
