摘要： A piston type compressor includes a suction valve mechanism. The suction valve mechanism includes a rotary valve coupled to a rotary shaft. A valve timing adjusting apparatus is capable of changing a relative rotational phase, which is a rotational phase of the rotary valve relative to the rotary shaft. Therefore, the compressor is capable of adjusting the valve timing of the rotary valve and has a reduced size in the axial direction.

摘要： As a swash plate of a variable displacement compressor slides along a drive shaft, while being inclined, the displacement of the compressor is changed. A step is formed on the drive shaft between the swash plate and a cylinder block. The step has a seat surface, which functions as a spring seat. The seat surface faces the swash plate. A return spring is located between the spring seat and the swash plate to urge the swash plate in a direction increasing the inclination angle. The step is directly formed on the drive shaft. Therefore, the number of components and the number of steps required for manufacturing the compressor are reduced.

摘要： The object of the present invention is to provide a control valve for a variable displacement compressor, which is used for controlling differential pressure between discharge pressure and suction pressure such that the differential pressure becomes equal to differential pressure set by duty ratio control, and improved in characteristics thereof when it is in the vicinity of the valve-closing position. A valve section for controlling the flow rate of refrigerant at discharge pressure Pd to thereby supply refrigerant at pressure Pc to a crankcase is implemented by a spool valve structures. A spool valve element and a shaft arranged coaxially with each other are configured such that the spool valve element and the shaft oppositely receive the discharge pressure Pd and the suction pressure Ps, respectively. The differential pressure between, the discharge pressure Pd and suction pressure Ps, which is to be controlled, is set by a pulse current supplied to a solenoid section which is duty ratio controlled. As a result, the spool valve element performing micro vibration due to duty ratio control is prevented from colliding against a valve seat when it is in the vicinity of the: valve-closing position, so that it is possible to enhance the lift characteristics of the valve, and improve durability of component parts of the same.

摘要： A piston type compressor includes a housing forming a cylinder bore. A drive shaft is supported by the housing. A cam plate is coupled to the drive shaft and is rotated by the rotation of the drive shaft. A piston is accommodated in the cylinder bore and is coupled to the cam plate. The rotation of the cam plate is converted into the reciprocating movement of the piston. In accordance with the reciprocating movement of the piston, gas is introduced into the cylinder bore, is compressed and is discharged from the cylinder bore. Compression reactive force is generated in compressing the gas by the piston, is transmitted to the housing through a compression reactive force transmission path and is received by the housing. A vibration damping member is made of a predetermined vibration damping alloy and is placed at least one location along the compression reactive force transmission path.

摘要： In a piston type compressor, a housing includes a cylinder head which defines a discharge chamber and a cooling chamber. The cooling chamber located adjacent to the discharge chamber surrounds the discharge chamber. The housing also defines a suction chamber, a compression chamber, and a crank chamber. The cooling chamber is isolated from the suction chamber. Gas is introduced from outside of the housing into the suction chamber. A rotary shaft is rotatably supported in the housing. The cam is accommodated in the crank chamber. A piston is operatively coupled to the rotary shaft through the cam. Rotation of the rotary shaft is converted to reciprocation of the piston. A seal member shuts communication between the cooling chamber and an atmosphere outside the compressor to seal an inside of the cylinder head. An introducing passage interconnects the cooling chamber and the crank chamber.

摘要： In an air-conditioning compressor with a revolving wobble plate driven by a driving shaft, the variable piston stroke height is regulated by directing pressure medium to flow from the high-pressure outlet compartment to the piston-drive compartment and/or from the piston-drive compartment to the intake suction compartment of the compressor. The driving shaft has a tubular end portion extending into a recess of the cylinder head. The medium flow from the high-pressure area to the piston-drive compartment is routed along the outside of the end portion, while the flow from the piston-drive compartment to the intake area is routed through the hollow channel inside the end portion. A flow-resisting element is arranged between the outside of the end portion and the wall of the recess in the cylinder head, so that the flow resistance towards the cylinder head is significantly greater than in the direction towards the driving compartment.

摘要： A rotary valve is used as a suction valve mechanism of a compressor. The rotary valve rotates integrally with a drive shaft to selectively open or close a suction passage of refrigerant gas from a suction chamber to a compression chamber in accordance with relative positions of the suction communicating passage and the suction guiding groove. An outer surface of the rotary valve directly slides on an inner surface of a valve accommodating chamber formed in a cylinder block, thereby constituting a slide bearing surface. The slide bearing surface rotatably supports the rear end of the drive shaft on housings. Accordingly, a piston type compressor which is comfortably used, inexpensively manufactured, and has high compression efficiency is provided.
