摘要： A compressor includes front and rear cylinder blocks, a drive shaft rotatably supported by the cylinder blocks, a swash plate mounted on the drive shaft, a plurality of cylinder bores defined in the cylinder blocks and located around the drive shaft, and a plurality of pistons respectively disposed in the cylinder bores. The pistons reciprocate by converting rotation of the drive shaft with the swash plate. A plurality of compression chambers are defined in the cylinder bores for compressing the gas supplied to the cylinder bores in accordance with the reciprocating movement of the pistons. Each compression chamber has dead volume defined by a space having a predetermined volume when the associated piston is at top dead center in each cylinder bore. A reference capacity is defined by the capacity when the piston is at a bottom dead center of the cylinder bore that has the smallest dead volume. The largest dead volume is greater than the minimum dead volume by approximately four percent of the reference capacity.

摘要： A compressor has a swash plate supported on a drive shaft for an integral rotation. The swash plate is coupled to a plurality of pistons reciprocally moveable in a cylinder block to compress gas therein. Reaction force of the compressed gas applied to the piston and causing axial load acting on the swash plate and the drive shaft is buffered by buffer structure. The buffer structure comprises a first bearing interposed between a first surface of the swash plate and the cylinder block. The buffer structure has a second bearing interposed between a second surface of the swash plate and the cylinder block. One of the bearings is arranged to be flexibly deformable to absorb the axial load while the other bearing is arranged to be rigid to receive the axial load and transmit the axial load to the cylinder block.

摘要： A compressor has an odd number of aligned pairs of cylinder bores. A double-headed piston is accommodated in each aligned pair of bores. The time at which gas is discharged from each cylinder bore is different from that of all of the other cylinder bores. The compressor has a pair of reducing devices, one reducing the pulsation amplitude of the gas discharged from the front cylinder bores and the other reducing the pulsation amplitude of the gas discharged from the rear cylinder bores. The reducing devices reduce the gas pulsation amplitudes of the front and rear cylinder bores at a substantially equal rate. Each reducing device includes a discharge chamber for receiving the gas discharged from the associated cylinder bores and a discharge passage connected to the discharge chamber. The discharge chambers of the reducing devices have equal volumes, and the discharge passages of the reducing devices have equal lengths and equal cross-sectional areas. This structure improves the vibration characteristics of the compressor and thus reduces noise.

摘要： A multi-piston swash plate type compressor for an air-conditioning system used in a vehicle such as an automobile, including a cylinder block body having a swash plate chamber formed therein for receiving a swash plate and cylinder bores formed therein for receiving pistons which are reciprocated by rotation of the swash plate. The compressor has a suction chamber which is fed with a refrigerant including lubricating oil from an evaporator of the air-conditioning system and a discharge chamber which feeds the compressed refrigerant to a condenser of the air-conditioning system. When the compressed refrigerant is discharged from the cylinder bore into the discharge chamber through a discharge reed valve, all of the discharged refrigerant is impinged on the peripheral and inner wall so as to separate the lubricating oil from the refrigerant, whereby an effective damping and sealing oil layer is formed between the discharge reed valve and the valve seat thereof.
