摘要： A reciprocating compressor includes double headed pistons forming front and rear sets of compression chambers on either side thereof and a pair of tapered rotary valves arranged for introducing a coolant gas into the compression chambers. The valves are urged into contact with valve chambers by springs and a drive shaft is urged in one axial direction by a prestress mechanism. The valve urging force for one rotary valve is different from the valve urging force for the other rotary valve, so that the rotary valves operate at different times and over different distances and the movements of the rotary valves are controlled to move the drive shaft in the same axial direction as the direction of the prestress mechanism.

摘要： A rotary valve is supported on a rotary shaft for an integral rotation. The rotary valve has a suction passage and a discharge passage. The suction passage connects a cylinder bore with a suction chamber according to the rotation of the rotary valve when a piston is in the suction stroke. The discharge passage connects the cylinder bore with a discharge chamber according to the rotation of the rotary valve when the piston is in the discharge stroke. The discharge passage includes a first passage and a second passage. The second passage communicates with the cylinder bore after the first passage has communicated with the cylinder bore after the first passage has communicated with the cylinder bore according to the rotation of the rotary valve. A discharge valve is mounted on the rotary valve. The discharge valve selectively opens and closes the first passage according to the difference between the pressures in the cylinder bore and in 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.
