摘要： A swash plate type variable displacement compressor has a housing, a drive shaft, a swash plate and a piston. The housing includes a cylinder block, a front housing, and a rear housing. The drive shaft is rotatably supported by the housing. The swash plate is connected to the drive shaft, and is integrally rotatable with the drive shaft and tiltable relative to the drive shaft. The piston engages with the swash plate through a pair of shoes. Rotation of the drive shaft is converted to reciprocation of the piston through the swash plate and the shoes, and the displacement of the compressor is adjusted by varying the inclination angle of the swash plate with respect to the axis of the drive shaft. The swash plate includes a base member made of copper series and a sliding layer coating a sliding surface of the base member with respect to the shoes.

摘要： A highly accurate and relatively inexpensive control valve for a compressor. The control valve includes a pressure sensitive portion that has a metal diaphragm, which is machined with a relatively low cost. The diaphragm is held between flanges. The pressure sensitive portion is attached to a control valve portion after being subjected to a pressure leak test. The control valve portion has an engaging piece and a positioning surface. The flange contacts the positioning surface and is fixed by the engaging piece. The positioning surface is formed such that the interval between the diaphragm and the top of the valve chamber becomes a predetermined value.

摘要： A control valve is located in a variable displacement compressor, which is used in a refrigerant circuit. The control valve includes a pressure-sensing member. The pressure sensing member moves a valve body in accordance with the pressure difference between a first pressure monitoring point and a second pressure monitoring point, which are located in the refrigerant circuit. A first spring and a second spring urge the pressure-sensing member in one direction. The spring constant of the first spring is smaller than that of the second spring. A solenoid urges the pressure-sensing member by a force, the magnitude of which corresponds to an external command. The solenoid urges the pressure-sensing member in a direction opposite to the direction in which the springs urge the pressure-sensing member. The control valve quickly and accurately controls the displacement of the compressor.

摘要： A compressor has a housing, which supports a rotary shaft, and a crank chamber. A swash plate is accommodated in the crank chamber. The compressor has an oil chamber located in the housing near a front end portion of the rotary shaft. The oil chamber has an inlet and an outlet. The outlet connects to the suction pressure zone. Either lubricant oil that is separated from refrigerant gas or refrigerant gas in the suction pressure zone flows into the oil chamber from the inlet and flows out from the outlet to the suction pressure zone. A seal mechanism seals the oil chamber. A seal seals between the oil chamber and the crank chamber. This permits an inclination angle of the swash plate to control accurately and smoothly while lubricating the seal mechanism optimally.

摘要： A suction port of a piston type compressor is formed in the shape similar to a portion of a sector with an apex portion of the sector removed. A distal end portion of a suction valve which can open and close the suction port has a contour line including a distal end forming line extending generally parallel to a distal end line of the suction port, and side lines. A gap between the distal end line of the suction port and the distal end forming line of the suction valve is substantially constant, and a gap between the distal end forming line and the circle of the cylinder bore is substantially constant. The ease of the inflow of a gas when the gas is sucked from the suction port to the cylinder bore is improved.

摘要： In a single-ended swash plate compressor, unbalanced thrust loads in either axial direction are reduced so that thrust loads acting on pistons in the direction of the front end are practically balanced by those in the direction of the rear end, for example, by connecting an intake chamber to a swash plate chamber by means of an adjustment valve to adjust the pressure in the swash plate chamber acting on the front end surfaces of the pistons to a suitable intermediate pressure by the action of the adjustment valve. In a single-ended swash plate compressor with pistons housed in both ends of a cylinder assembly comprising one set of pistons for guidance and another set for compression, discharge pressure is introduced into some of the cylinder bores housing guide pistons and intake pressure is introduced into the cylinder bores housing guide pistons into which discharge pressure is not introduced.

摘要： A swashplate type variable-displacement compressor includes a compressor housing defining therein a crank chamber, a refrigerant suction chamber, a refrigerant discharge chamber, and a low-pressure refrigerant passage connected to an evaporator outlet, and a pressure regulator. The pressure regulator controls the amount of low-pressure refrigerant gas flowing into the refrigerant suction chamber by regulating a differential pressure between the pressure in the refrigerant suction chamber and the pressure in the crank chamber. The pressure regulator is comprised of a flow control valve including a first spring-loaded, normally-closed spool valve and a pressure chamber accumulating the working pressure used to force the spool valve toward its fully-opened position, and a flow control valve actuating mechanism including a communication passage through which the refrigerant discharge chamber is communicated with the pressure chamber, a second spring-loaded, normally-closed pilot valve provided in the communication passage, and an electromagnetic solenoid controlling the opening of the pilot valve so that the opening increases with an increase in exciting current supplied to the solenoid. The pilot valve serves to introduce high-pressure refrigerant gas in the refrigerant discharge chamber into the pressure chamber as the working pressure with the opening controlled by the solenoid.
