摘要： An improved displacement control valve incorporated in a variable displacement compressor. The control valve is installed in an accommodating hole formed in a rear housing of the compressor. A cap is attached to a housing body of the control valve. A pressure sensing chamber is defined between the cap and the housing body. A pressure sensing member, or bellows, is located in the pressure sensing chamber. The bellows moves a valve body in accordance with pressure introduced into the pressure sensing chamber. A tubular protector, which is made of an elastic material, is attached to the cap. The control valve is installed in the rear housing by inserting the valve, cap first, into the accommodating hole. During this installation, the protector prevents the cap from directly contacting the housing or inner wall of the accommodating hole. The cap is therefore not deformed. The performance of the control valve is therefore improved.

摘要： A compressor has a cam plate located in a crank chamber and mounted on a drive shaft and a piston coupled to the cam plate and located in a cylinder bore. The piston compresses gas supplied to the cylinder bore from a separate external circuit by way of a suction chamber and discharges the compressed gas to the external circuit by way of a discharge chamber. The cam plate is tiltable between a maximum inclined angle position and a minimum inclined angle position with respect to a plane perpendicular to an axis of the drive shaft according to a difference between the pressure in the crank chamber and the pressure in the cylinder bore. The piston moves by the stroke based on an inclination of the cam plate to control the displacement of the compressor. A valve is placed between the discharge chamber and the external circuit. The valve selectively connects and disconnects the discharge chamber with the external circuit based on a difference between the pressure acting on the upstream side of the valve and the pressure acting on the downstream side of the valve.

摘要： A compressor housing and method of manufacture and assembly are disclosed. The compressor housing includes a cylinder block and a front housing. An annular projection is formed on the front end of the cylinder block. An annular groove is formed on the rear end of the front housing. The cylinder block and the front housing are secured to each other to prevent the front housing from being displaced in relation to the cylinder block by engaging the annular projection with the annular groove. A gasket is located between the front end of the cylinder block and the rear end of the front housing secured to each other to seal between the cylinder block and the front housing. This compressor and its method of manufacture reduce the amount of misalignment between a shaft bore in the cylinder block and a shaft bore in the front housing, which improves the performance of the compressor.

摘要： A variable displacement compressor includes a crank chamber for housing a cam plate, a suction chamber, and a discharge chamber. The apparatus includes a first passage connecting the crank chamber with the discharge chamber to discharge the pressure in the crank chamber to the suction chamber to change the suction pressure. A second passage connects the discharge chamber with the crank chamber to supply the pressure from the discharge chamber to the crank chamber increase the pressure in the crank chamber. A valve is disposed in the second passage to open or close the second passage. When the cam plate speed exceeds a certain predetermined amount, a solenoid is actuated to increase the size of the valve opening. As such, the load on the compressor during high speed rotation of the compressor drive shaft is reduced and the durability of the compressor is increased.

摘要： A compressor has a control valve that adjusts the pressure difference between a crank chamber and a cylinder bore for controlling the inclination of a drive plate. The control valve protrudes outward from the compressor housing. The compressor also has a support protruding outward from the front housing and a leg protruding outward from the cylinder block. The outer ends of the support and the leg extend further from the compressor than the furthest extremity the control valve. Therefore, when the compressor is placed on a flat surface, the support and the leg prevent the control valve from contacting the surface. This protects the control valve from damage during transport and handling.

摘要： A cam plate is mounted on a drive shaft in a crank chamber. A plurality of pistons are operably coupled to the cam plate. The rotation of the drive shaft is converted to a linear reciprocal movement to compress and discharge refrigerant gas containing oil mist. An extracting passage extracts the refrigerant gas from the crank chamber to remove an excessive pressure in the crank chamber. The extracting passage is open to an accommodating chamber which receives the refrigerant gas from the passage. A bearing is disposed in the accommodating chamber and receives an axial load acting on the drive shaft. A bolt absorbs an assembly tolerance of the bearing. A first protuberance is provided on the bearing protruding in a radial direction with respect to the drive shaft so as to become aligned with the passage. The first protuberance engages an inner surface of the accommodating chamber to prevent rotation of the bearing.

摘要： A variable displacement compressor includes a hinge mechanism having a pair of support arms integrally formed with and protruding from the drive plate, and guide pins which connect the swash plate with the support arms. Each support arm is formed having a unshaped cutaway portion defining a channel for supporting ball portion of the hinge mechanism. The ball portion pivotably secured in the channel portion of the support arm, is attached to guide pin which in turn connects to a bracket protruding from the swash plate. The ball portion transmits pressure & rotational forces generated by the pistons and rotational force of the drive plate respectively. The forces cause the ball portion of the hinge mechanism to impinge upon pre selected surface area of the u-shaped support arm. By impinging on these preselected surface areas of the u-shaped support arm, the ball portion will not disengage from the channel portion of the support arm. Moreover the shape of the support arm increases the motility of the ball portion and associate guide pin secured within the support arm. The guide pin is slidably inserted into either the support arm or the swash plate, and is rotatably supported by means of the support arm.

摘要： A refrigerant circuit includes a compressor and an expansion valve. The expansion valve is connected to a discharge muffler of the compressor by a high pressure conduit. The expansion valve is also connected to a suction passage of the compressor by a low pressure conduit. The high pressure conduit includes a condenser and the low pressure conduit includes an evaporator. A check valve is located between the discharge muffler and the high pressure conduit to selectively connect and disconnect the high pressure conduit with the discharge muffler. A relief valve is attached to the discharge muffler upstream of the check valve. If the pressure in the compressor is abnormally high when the check valve closes, the relief valve releases the abnormally high pressure from the discharge muffler. Therefore, if the check valve fails to function, the relief valve prevents the pressure in the compressor from being abnormally high.
