摘要： A method of processing a valve mechanism which includes a valve body having a shut-off surface in the form of a convex spherical surface, a valve hole, a valve seat formed by an opening of the valve hole, and a spring which urges the valve body toward the valve seat, wherein the valve mechanism is so formed that the valve body resists the urging force of the spring in accordance with the pressure increase in the valve hole to be separate from the valve seat, includes the steps of: preparing a processing tool having a processing surface in the form of a convex spherical surface which has the same curvature radius as the shut-off surface of the valve body; positioning the processing tool to the valve seat; and forming the valve seat along the form of the processing surface by pushing the processing surface of the processing tool against the valve seat.

摘要： A controller for a variable displacement compressor that maintains high displacement while preventing excessive increase in discharge pressure. The controller includes a pressure sensing mechanism for detecting pressure of a suction pressure region in the compressor. A suction pressure controlling means controls the displacement of the compressor so that the pressure detected by the pressure sensing mechanism is converged to a predetermined suction pressure setting. A sensor detects pressure of a discharge pressure region in the compressor. A discharge pressure controlling means controls the displacement of the compressor so that the pressure detected by the sensor is converged to a predetermined discharge pressure setting. When the pressure detected by the sensor is greater than a threshold pressure, an ECU switches the control of the compressor from control with the suction pressure controlling means to control with the discharge pressure controlling means.

摘要： A vibration isolator includes a first metallic mounting member; a metallic body member disposed away from the first metallic mounting member in the vibration input direction; an elastic body portion elastically connecting the first metallic mounting member and the metallic body member; and a second metallic mounting member. The metallic body member includes a flange portion protruding radially outward from a part of its end facing the first metallic mounting member and a first protrusion protruding radially outward from the remaining part of the end to a greater extent than does the flange portion. The opposite end of the metallic body member is plugged with a seal member to thereby form a liquid chamber within the metallic body member. The second metallic mounting member is fixedly press-fitted onto the metallic body member and includes a second protrusion. The first and second protrusions are superposed to thereby form a stopper portion. The stopper portion is covered and held by a stopper covering portion.

摘要： A control valve is used for a variable displacement compressor. The compressor has a crank chamber and a bleed passage. The control valve includes a valve housing. A valve chamber is defined in the valve housing. A valve body is accommodated in the valve chamber for adjusting the opening size of the bleed passage. A pressure sensing chamber is defined in the valve housing. A pressure sensing member separates the pressure sensing chamber into a first pressure chamber and a second pressure chamber. The pressure at a first pressure monitoring point is applied to the first pressure chamber. The pressure at a second pressure monitoring point located is applied to the second pressure chamber. The pressure sensing member moves the valve body in accordance with the pressure difference between the first pressure chamber and the second pressure chamber such that the displacement of the compressor is varied to counter changes of the pressure difference. The pressure sensing member is a bellows or a diaphragm.

摘要： A displacement control mechanism used for compressor is installed in a refrigerant circuit. The compressor has a bleed passage and a supply passage. The displacement control mechanism includes a first control valve and a second control valve. The first control valve includes a first valve body and a pressure sensitive member. The first valve body adjusts the opening size of the supply passage. The pressure sensitive member moves in accordance with a pressure in the refrigerant circuit. A pressure detection region is located downstream of the first valve body. The second control valve includes a second valve body. The second valve body adjusts the opening size of the bleed passage. The second valve body moves in accordance with the pressure of the pressure detection region. When the pressure of the pressure detection region increases, the second control valve decreases the opening size of the bleed passage. This permits to start with rapid cooling performance.

摘要： A capacity type refrigerant compressor having a compression chamber in which a refrigerant introduced from a suction system is compressed and discharged as a compressed high pressure refrigerant, and an oil-separating and lubricating system for lubricating an interior of the compressor by an oil separated from the compressed refrigerant, which has an oil-separating unit to separate the oil from the compressed refrigerant, an oil-storing chamber storing the separated oil, an oil-supply passage to supply the oil from the oil-storing chamber to the suction system, a pressure-operated valve arranged in the oil supply passage to regulate an amount of flow of the oil, which includes a valve chamber and a movable valve spool in the valve chamber to control a communication between the upstream and downstream of the oil-supply passage. The valve spool element moves in response to a change in a pressure differential between pressures in the compression chamber and the suction system, and blocks the oil flow in the oil-supply passage when the pressure differential is overcome by a spring force arranged in the valve chamber.

摘要： Disclosed is a compressor designed to facilitate the assembling of the thrust bearing and reduce noise. A swash plate which moves in responsive to the drive shaft is arranged in a crank chamber defined in a pair of cylinder blocks. Ring washers are held between both bosses of the swash plate and seats formed on both cylinder blocks. Wedge-like clearances are formed between the washers and the seats of the cylinder blocks for the effective introduction of the refrigerant gas by the yawing of the swash plate which occurs as the compressor runs. At this time, the washers, together with the lubrication oil mist contained in the refrigerant gas, constitute the dynamic bearing to support the swash plate and permit the relative movement of the swash plate to the cylinder blocks.
