摘要： The solenoid actuator (26) is designed to be installed within a mounting bore (22) formed in a support housing (24). The solenoid actuator (26) is provided at its top with an end cap (46) made of molded plastics which is configured to be closely fitted in the mounting bore(22) to close the opening of the bore. When the actuator is installed within the mounting bore (22), the end cap (46) protects underlying yoke member (40/64), armature (80) and magnetic pole piece (74) from attack by corrosive substance.

摘要： A control valve used in a variable displacement compressor includes a valve chamber (46), a valve body (43) and a pressure sensing chamber (48). A pressure sensing ball is movably located in the pressure sensing chamber (48) and divides the pressure sensing chamber (48) into a first pressure chamber (55) and a second pressure chamber (56). First and second pressure monitoring points (P1, P2) are located in a refrigerant circuit. The first pressure chamber (55) is exposed to the pressure at the first pressure monitoring point (P1). The second pressure chamber (56) is exposed to the pressure at the second pressure monitoring point (P2). The ball is displaced based on the pressure difference between the first pressure chamber (55) and the second pressure chamber (56). The position of the valve body (43) is determined based on the position of the pressure sensing member (54).

摘要： A control valve (40) is provided to be mainly used in a clutch-less compressor of the type in which displacement of the compressor is varied depending on the inclination of a drive plate (17) which varies depending on the crank pressure. The control valve (40) includes biasing means (47,52) that applies force to a valve body (46), a force transferring member (65) that urges the valve body (46) to forcibly open the valve against the force of the biasing means (47,52) and the pressure difference between a crank chamber (3) and a suction chamber (8) of the compressor, and a solenoid assembly (60) to actuate the force transferring member (65). The valve remains closed when no electric current is supplied to the solenoid assembly (60), regardless of the crank pressure or the suction pressure. This facilitates minimum displacement operation of the compressor for a desired period of time and therefore makes the valve suitable for a clutch-less type compressor that is directly connected to an engine with a belt and/or a pulley.

摘要： A control valve (50) controls the displacement of a variable displacement type compressor. The compressor includes a crank chamber (5), suction chamber (21), a bleed passage (27), and a supply passage (28). The control valve has a supply side valve (V2), a transmission rod (80), and a relief side valve (V1). The transmission rod (80) connects the relief side valve (V1) with the supply side valve (V2). The relief side valve (V1) includes a passage chamber (53) constituting part of the bleed passage (27). The passage chamber (53) is separated into a first area (53a), which is connected to the crank chamber (5), and a lower area (53b), which is connected to the suction chamber (21). A pressure sensing member (60) moves the relief side valve body (61) in accordance with the pressure in the upper area (53a). The effective pressure receiving area (A) of the sensing member (60) is substantially equal to the cross sectional area (B) of the passage chamber (53) that is sealed by Lhe relief side valve body (61).

摘要： A torque limiting mechanism for transmitting power from an external drive source (Eg) to the drive shat (17) of a compressor (C). A pulley (33), which is coupled to the external drive source, has elastic members (44). A hub, which is attached to the drive shaft, has engaging portions (41). A coupler member (59) is located between the pulley (33) and the hub (38). The coupler member is engaged with the elastic members (44) and with the engaging portions (41) such that power is transmitted from the pulley to the hub. The urging members urge the coupler member (59) such that the coupler member is disengaged from the engaging portions (41). When power is transmitted from the pulley to the hub, the elastic members (44) maintain the coupler member (59) engaged with the elastic members (44) and with the engaging portions (41). When load generated due to power transmission exceeds a predetermined level, the elastic members (44) are deformed such that the coupler member (59) is disengaged from the elastic members (44). When disengaged from the elastic members (44), the coupler member is disengaged from the engaging portions (44).

摘要： An automobile moves at a traveling speed in accordance with the position of an acceleration pedal (89). A compressor is driven by the engine (20) of the automobile. The discharge displacement of the compressor is adjusted by an external control procedure. When the position of the acceleration pedal (89) reaches a determining value, or above at which it is determined that engine power is needed for accelerating the vehicle, the compressor is controlled such that the discharge displacement decreases. The determining value is selected by a controller (80) in relation to the traveling speed detected by a speed sensor (87). The determining value increases as the speed increases.

摘要： An improved control apparatus for controlling the displacement of a variable displacement compressor. A control valve 46 includes an operating rod 53, which is urged by a force based on a differential pressure PdH-PdL between two pressure monitoring points P1, P2, which are located in a refrigeration circuit. The control valve causes the compressor to seek a target displacement. A computer limits the target displacement when the demand for cooling is decreasing to improve fuel economy and to extend the life of the compressor.

摘要： A control valve is used for a cooling apparatus having a compressor including a displacement variation mechanism and an external refrigerant circuit connected to the compressor to form a cooling circuit. The discharge displacement of the compressor is regulated by controlling a control pressure, which acts on the displacement control mechanism. The control valve has a housing and an internal passage. The internal passage includes a valve chamber defined in the housing. A valve body is located in the valve chamber and controls the opening degree of the internal passage. A first pressure sensing structure senses the differential pressure between two pressure monitoring points in the cooling circuit, that is, a primary pressure, and transmits a force corresponding to the primary pressure to the valve body. A second pressure sensing structure senses a secondary pressure, which is different from the primary pressure, and applies the secondary pressure to the valve body. The valve body is positioned in the valve chamber by a combination of forces corresponding to the primary pressure and the secondary pressure, and the opening degree of the internal passage is controlled accordingly.
