    摘要: An improvement of a piston type compressor is disclosed. The compressor has a cylinder block that includes a plurality of cylinder bores and a plurality of suction passages. Each of the suction passages extends through the cylinder block to connect a crank chamber with a suction chamber. The suction chamber is connected with the cylinder bores via a plurality of suction ports located in association with the cylinder bores. Each cylinder bore accommodating a piston that moves therein to circulate gas between the compressor and an external gas circuit. The gas introduced into the crank chamber from the external gas circuit is supplied to the suction chamber through each suction passage and is supplied from the suction chamber to each cylinder bore through an associated suction port. The suction passages are smaller in number than the cylinder bores. The suction ports are disposed in the vicinity of an opening of the suction passages.

    摘要: A compressor includes a housing body and a drive shaft rotatably supported in the housing body. A drive plate is mounted on the drive shaft. Cylinder bores are defined in the housing body. Pistons are operably coupled to the drive plate and are disposed in the cylinder bores. The drive plate converts rotation of the drive shaft to reciprocating movement of the pistons in the cylinder bores. Each piston compresses gas supplied from a suction chamber to the associated cylinder bore and discharges the compressed gas to a discharge chamber. Force to minimize displacement of the drive shaft in the axial direction thereof adjusts in accordance with at least one of pressure in the discharge chamber and a rotation speed of the drive shaft.

    摘要: A reciprocating piston type compressor for compressing refrigerant gas is provided with a main housing which includes a plurality of parallel cylinder bores arranged around the longitudinal axis of the cylinder block. The main housing has first and second cylinder blocks connected to each other by a plurality of bolts, the cylinder blocks including inner clamping faces and abutting faces. A plurality of pistons are slidably provided within the cylinder bores. An axially extending drive shaft is supported by the main housing for rotation through a pair of bearings. A swash plate is mounted on the drive shaft for rotation with the drive shaft. A pair of thrust bearings are provided between the swash plate and the inner clamping faces of the cylinder blocks to clamp and hold the swash plate therebetween. The clamping force on the thrust bearings from the inner clamping faces is controlled so that the clamping force does not exceed a predetermined allowable upper limit when the compressor is assembled.

    摘要: A reciprocating piston type compressor having a cylinder block, a plurality of cylinder bores, and at least a housing closing an end of the cylinder block. The housing contains a suction chamber for a refrigerant gas to be compressed and a discharge chamber for the compressed refrigerant gas discharged from the cylinder bores in response to reciprocation of a plurality of pistons. The compressed gas is discharged through discharge ports closed by a discharge valve element having a plurality of integral discharge reed-valves movable between a closed positions and a predetermined open positions. The open position is defined by a stop unit integrally formed in an inner wall of the housing. The stop unit has a plurality of flat stop faces formed on the inner wall to permit free ends of the discharge reed-valves to come into contact engagement therewith, when the discharge reed-valves are moved from the closed positions to the open positions.

    摘要: A swash plate type compressor incorporating therein a swash plate having an annular rail raised from each flat face thereof for providing a sliding-contact surface being in contact with sliding-contact surface portions of respective shoes which constitute a rotation-to-reciprocation conversion unit arranged between the swash plate and double-headed pistons reciprocating axial cylinder bores of the compressor. The sliding-contact surfaces of respective shoes bulge outward and have a radius of curvature "R" in the range of 800 through 1600 millimeters which is smaller than that of the conventional shoes of a swash plate type compressor, so that relatively large wedge shaped gaps are formed between the respective shoes and the swash plate to thereby stably and constantly hold lubricating oil.
