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 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： 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 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 variable displacement type compressor having a piston accommodated in a cylinder bore, a swash plate accommodated in a crank chamber for reciprocating the piston and a drive shaft for tiltably and rotatably supporting the swash plate. The swash plate includes projections that extend toward a thrust bearing and have outer surfaces that contact the thrust bearing. A shaft hole within which the drive shaft is located between the projections. The shaft hole has an opening that opens adjacent to the projections. A recess is formed at the end of the shaft hole adjacent to the projections. A hardening method is performed on the wall of the through hole and on the outer surfaces of the projections to improve wear resistance. The hardening method prevents overheating of localized areas of the swash plate.

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.

摘要： A compressor having a cam plate disposed in a crank chamber and mounted on a drive shaft. 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 differential pressure in the crank chamber and in a cylinder bore. The cam plate varies the stroke of a piston based on an inclination thereof to control the displacement of the compressor. A supply passage connects a discharge chamber with the crank chamber to deliver the gas from the discharge chamber to the crank chamber. The supply passage has an inlet that is open in the discharge chamber. A control valve is disposed midway on the supply passage. The control valve adjusts the amount of the gas introduced into the crank chamber from the discharge chamber through the supply passage to control the pressure in the crank chamber. A filter is disposed at the inlet of the supply passage to filter the oil. The filter captures foreign matter mixed with the oil when the gas containing the oil is introduced into the supply passage from the discharge chamber.

摘要： 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.
