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 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 torque limiting mechanism for transmitting power from an external drive source to the drive shat of a compressor. A pulley, which is coupled to the external drive source, has elastic members. A hub, which is attached to the drive shaft, has engaging portions. A coupler member is located between the pulley and the hub. The coupler member is engaged with the elastic members and with the engaging portions such that power is transmitted from the pulley to the hub. The urging members urge the coupler member such that the coupler member is disengaged from the engaging portions. When power is transmitted from the pulley to the hub, the elastic members maintain the coupler engaged with the elastic members and the engaging portions. When load generated due to power transmission exceeds a predetermined level, the elastic members are deformed such that the coupler member is disengaged from the elastic members. When disengaged from the elastic members, the coupler member is disengaged from the engaging portions.

摘要： A control valve includes an accommodation cylinder, a coil, a stator, a plunger, and a valve body. Electromagnetic force is generated between the stator and the plunger and the plunger moves relative to the stator. The valve body adjusts the opening degree of a valve hole. A flat surface and a peripheral wall are formed in an end of the stator. The peripheral wall has a tapered cross-section with an inclined inner surface. The inclined inner surface and the flat surface define a recess. The plunger has a frustum portion. The frustum portion includes a flat distal surface and an annular inclined surface. The taper angle of the peripheral wall is equal to or less than twenty degrees. The diameter of the flat distal surface of the frustum portion is equal to or greater than eighty percent of the largest diameter of the annular inclined surface.

摘要： A control valve is used for a variable displacement compressor installed in a refrigerant circuit of an air conditioner. The compressor has a control chamber and a control passage, which connects the control chamber to a pressure zone in which the pressure is different from the pressure of the control chamber. The control valve has a valve body, which is accommodated in the valve chamber for adjusting the opening size of the control passage. A pressure sensing member moves in accordance with the pressure difference between two pressure monitoring points located in the refrigerant circuit. The pressure sensing member moves the valve body such that the displacement of the compressor is varied to counter changes of the pressure difference. The force applied by an actuator corresponds to a target value of the pressure difference. The pressure sensing member moves the valve body such that the pressure difference seeks the target value. An urging member is accommodated in the valve chamber. The urging member urges the valve body in a direction to open the control passage.

摘要： A variable displacement compressor has a housing, a drive shaft, a rotor, a swash plate, a piston and a decelerating mechanism. The housing includes a cylinder bore and supports the drive shaft. The rotor is secured to the drive shaft. The swash plate is operatively connected to the rotor and the drive shaft so as to rotate therewith and varies its inclination angle relative to the drive shaft. The piston is connected to the swash plate so as to reciprocate in the cylinder bore with rotation of the swash plate. A stroke of the piston varies in accordance with the inclination angle of the swash plate. The deceleration mechanism between the rotor and the swash plate decelerates the inclination speed of the swash plate in a range from a near maximum inclination angle to the maximum inclination angle when the swash plate inclines to increase the stroke of the piston.
