Abstract: A gasket is provided between a cylinder block and a valve plate. By providing a through hole at a position near the center of the gasket, bending moment acting on the cylinder block is reduced, and hence deformation of the cylinder block is restrained. As a result, reciprocating motion of a piston and rotational motion of a rotary valve are performed smoothly.

Abstract: A swash plate type compressor used for the air conditioner of an automobile is presented. The compressor has a structure where pulsation pressure caused when refrigerants are compressed and discharged is reduced, thereby permitting noise at the time of driving to be substantially reduced. The compressor can embody the structure by distributing and discharging refrigerant that has been compressed by a plurality of pistons and discharged from a plurality of bores into at least two discharge holes, wherein a frequency of the pulsation pressure is increased in proportion to the number of the discharge holes, but the strength of the pulsation pressure is decreased in inverse proportion to the number of discharge holes. Therefore, the driving noise of the compressor that is formed in proportion to the strength of the pulsation pressure is considerably decreased.

Abstract: A shaft sealing assembly is located in a suction chamber of a swash plate type compressor to seal the space between a drive shaft and a housing. A first end portion of the drive shaft is supported by a first radial bearing. A second end portion of the drive shaft is supported by a second radial bearing. The suction chamber is closer to the first end portion of the drive shaft than the first radial bearing is. An axial passage is formed in the drive shaft to connect the suction chamber to the crank chamber. An inlet of the axial passage is closer to the second end portion than the second radial bearing is. An outlet of the axial passage is closer to the second end portion than the first radial bearing is.

Abstract: An external control variable displacement compressor varies its displacement based on the pressure in a control chamber. The compressor has a valve chamber defined in a housing. The valve chamber has an opening to accommodate an electrically operative control valve. The control valve controls pressure in the control chamber due to an external electrical signal. An electrical power supply line is connected to the control valve, the power supply line being in contact with an opening of the valve chamber. The valve chamber opening is surrounded by a circumferential wall. An agonic surface formed on the circumferential wall is constituted of a rounded surface formed by rounding a corner of the opening and/or a chamfered surface formed by chamfering a top of the opening, and is formed on a part of or the entire circumferential wall. The power supply line is to be in contact with the agonic surface.

Abstract: A power transmission mechanism transmits power of an external drive source to a rotary shaft. The transmission mechanism has a first rotor rotated by the external power source. A second rotor is connected to the rotary shaft. The second rotor is coaxial with the first rotor and coupled to the first rotor transmit power to the first rotor. A disconnecting body disconnects power transmission from the first rotor to the second rotor when an excessive transmission torque is generated between the rotors. A dynamic damper is provided in at least one of the rotors. The dynamic damper has a weight that swings like a pendulum. The axis of the pendulum motion of the weight is separated by a predetermined distance from and is substantially parallel to the rotation axis of the corresponding rotor.
