    摘要: A discharge valve mechanism in a compressor for compressing refrigerant gas includes a valve plate and a discharge valve plate. The valve plate forms a discharge port into which the compressed refrigerant gas is discharged. The discharge valve plate is located between the valve plate and a rear housing and includes a support portion, a connecting portion and a discharge valve. The support portion is sandwiched between the valve plate and the end surface of the rear housing. The connecting portion is bendably cantilevered from the support portion. The connecting portion extends to an opposite side of the discharge port so as to bypass the discharge port from the support portion. The connecting portion has a free end portion. The discharge valve extends from the free end portion to the discharge port toward the support portion for opening and closing the discharge port.

    摘要: A swash plate type variable displacement compressor includes a cylinder block defining a cylinder bore. A housing is fixed to the cylinder block and defines a crank chamber. A drive shaft is rotatably supported by the housing and the cylinder block. A swash plate is supported by the drive shaft in the crank chamber and is inclinable with respect to the axis of the drive shaft. A piston is accommodated in the cylinder bore so as to define a compression chamber in the cylinder bore and is coupled to the swash plate. A control mechanism includes a bleed passage for controlling the pressure in the crank chamber. The compressor is formed such that lubricating oil in the crank chamber is discharged into at least one of the suction chamber, the discharge chamber and the compression chamber while the inclination angle of the swash plate is substantially a maximum inclination angle.

    摘要: A compressor includes a compression chamber, a discharge chamber, a discharge port forming member and a discharge valve The compression chamber is formed in a cylinder block and in the compression chamber a refrigerant is compressed. The discharge chamber is formed in a cylinder housing which is fixed to the cylinder block. The refrigerant in the compression chamber is flowed into the discharge chamber. The discharge port interconnects the compression chamber and the discharge chamber. The discharge valve opens and closes the discharge port, and has a valve member and an arm member. The valve member faces to the discharge port for opening and closing the discharge port. The arm member urges the valve member toward the discharge port. The arm member and the valve member are integrally joined with each other.
