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： In a discharge pulsation damping apparatus of a compressor according to this invention, an expansion muffler 46 and a resonance muffler 58 each having a predetermined capacity are defined inside cylinder blocks 11 and 12 through partitions 59 and 60 so that the resonance muffler 58 is situated at a position higher than the expansion muffler 46 in a gravitational direction (vertical direction). The expansion muffler 46is connected to discharge chambers 38 and 39 and to an outlet 48, and both mufflers 46 and 58 are communicated by a communication passage 61 formed in the partitions 59and 60. The capacity of the resonance muffler 58, the open sectional area of the communication passage 61 and its passage length are set to values such that a pressure change capable of offsetting specific frequency components of the discharge pulsation inside the expansion muffler 46 can be generated inside the resonance muffler 58. The lubricant condensed inside the resonance muffler 58 is fed back into the expansion muffler 46 through the communication passage 61.

摘要： A refrigeration suction mechanism used in a piston type compressor. The compressor comprises a rotary shaft, a plurality of pistons, a compression chamber and a rotary valve. The pistons are arranged in a circumference of the rotary shaft to reciprocate in conjunction with a rotating motion of the rotary shaft through a cam member. An end surface of one of said pistons reciprocates in the compression chamber. The rotary valve includes an introducing passage which allows refrigerant to flow into the compression mechanism through an end opened on an outer surface of the rotary valve. The refrigeration suction mechanism comprises a suction passage and a reactive force transmitting mechanism. The suction passage communicates with the cylinder bore and intermittently communicates with the end of the introducing passage in conjunction with a rotating motion of the rotary valve. The reactive force transmitting mechanism transmits a reactive force applied on one of the pistons that is in a discharging stroke so as to press the rotary valve against a mouth of the suction passage which communicates with a cylinder bore that contains the piston in the discharging stroke.

摘要： A double-headed piston compressor includes a pair of opposite discharge chambers. Each discharge chamber is defined by a large annular wall and a small annular wall. The annular walls are located about the axis of the drive shaft. A limit wall is formed in each housing and is located in each discharge chamber. Each limit wall extends substantially radially to connect the annular walls near the outlet of the discharge chamber. Therefore, each discharge chamber forms a gas passage, which extends circularly about the axis of the drive shaft from the limit wall to the outlet. Compressed gas discharged from the cylinder bores to each discharge chamber through the discharge ports flows in one direction toward the outlet. As a result, pulsation of compressed gas is attenuated.
