摘要： A swash-plate type compressor comprising a cylinder block, front and rear valve plates, and front and rear housings attached to either end of the cylinder block over the valve plates. A swash-plate is accommodated in the cylinder block to reciprocally move a plurality of double headed pistons which form compression chambers on either side thereof. A drive shaft carries the swash-plate and is supported by a pair of tapered roller bearings. Each of the tapered roller bearings is secured in the central hole of each valve plate. Also, each valve plate is coupled to the cylinder block in a locating projection-locating hole fitting relationship to effect centering the drive shaft relative to the cylinder block. In addition, a suction passage is arranged to introduce the refrigerating gas from the swash-plate chamber to each of the compression chambers in such a manner as to reduce the radius of the cylinder block.

摘要： A compressor has a plurality of cylinder bores defined around a rotary shaft in a cylinder block and a plurality of double-headed pistons accommodated in the respective cylinder bores. The pistons compress refrigerant gas in a plurality of front and rear compression chambers defined in the bores in the front and rear of the respective pistons according to the rotation of a cam plate mounted on the rotary shaft. The compressor has bearing that receive thrust loads applied to the rotary shaft during operation of the compressor. The pistons create a net thrust load determined by the difference between the maximum of the sum of loads applied to the front sides of the pistons by the refrigerant gas in the front compression chambers and the maximum of the sum of loads applied to the rear sides of the pistons by the refrigerant gas in the rear compression chambers. The pistons transfer the net thrust load to the rotary shaft in a predetermined direction.

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 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.
