    摘要： A control valve used in a variable displacement compressor. The valve includes a valve chamber having a valve hole. A valve body is accommodated in the valve chamber for selectively closing and opening the valve hole. An opening spring urges the valve body in a direction opening the valve hole. An actuator generates force in a direction closing the valve hole. A solenoid rod transmits the force of the actuator to the valve body. A pressure sensing chamber is defined independently from the valve chamber to receive refrigerant from a suction passage. A pressure sensing member is located in the sensing chamber for sensing the pressure in the sensing chamber. A pressure sensing rod transmits the pressure sensed by the sensing member to the valve body. A compression spring, a cap and stoppers maintain proper alignment of the pressure sensing member. The valve body is moved based on the refrigerant pressure sensed by the sensing member, the force of the spring and on the force of the actuator.

    摘要： A control valve in a compressor that adjusts the discharge displacement based on controlling of an inclination of a cam plate. The compressor includes a supply passage for connecting a discharge chamber with a crank chamber. The control valve is placed midway on the supply passage for adjusting the amount of the gas introduced into the crank chamber from the discharge chamber. The control valve has a valve hole and a valve chamber respectively disposed midway on the supply passage. A valve body is located in the valve chamber to adjust the opening size of the valve hole. A reacting member reacts to the pressure in the first area. The reacting member moves the valve body via a first rod in accordance with the pressure in the first area. A solenoid is opposed to the reacting member with respect to the valve body. The solenoid has a fixed core, a plunger and a plunger chamber. Electric current sent to the solenoid produces a magnetic attractive force between the core and the plunger in accordance with a magnitude of the current. A second rod is placed between the plunger and the valve body to urge the valve body by the magnetic attractive force. The discharge chamber is connected with the valve chamber. The crank chamber is connected with the valve hole and the plunger chamber.

    摘要： A control valve 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 which varies depending on the crank pressure. The control valve includes biasing means that applies force to a valve body, a force transferring member that urges the valve body to forcibly open the valve, and a solenoid assembly to actuate the force transferring member. The valve remains closed when no electric current is supplied to the solenoid assembly, 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 controls the displacement of a variable displacement type compressor. The compressor includes a crank chamber, suction chamber, a bleed passage, and a supply passage. The control valve has a supply side valve, a transmission rod, and a relief side valve. The transmission rod connects the relief side valve with the supply side valve. The relief side valve includes a passage chamber constituting part of the bleed passage. The passage chamber is separated into a first area, which is connected to the crank chamber, and a lower area, which is connected to the suction chamber. A pressure sensing member moves the relief side valve body in accordance with the pressure in the upper area. The effective pressure receiving area of the sensing member is substantially equal to the cross sectional area of the passage chamber that is sealed by the relief side valve body.

    摘要： A control valve controls the displacement of a variable displacement type compressor. The compressor has a crank chamber, a bleed passage, and a supply passage. An outlet valve portion located on the bleed passage to control the opening of the bleed passage. An inlet valve portion is located on the supply passage to control the opening of the supply passage. A transmission rod extends between the outlet valve portion and the inlet valve portion to connect the outlet valve portion to the inlet valve portion. The transmission rod moves axially. A through hole is located in the inlet valve portion to receive a part of the transmission rod. The through hole constitutes a part of the supply passage. A clearance is formed between the transmission rod and the through hole to constantly connect the discharge pressure zone to the crank chamber.

    摘要： A displacement control valve included in a variable displacement compressor. The compressor includes a fluid passage for connecting a crank chamber to a discharge chamber. The control valve includes a valve chamber connected to the crank chamber through the fluid passage, a valve hole connected to the discharge chamber through the fluid passage, and a valve body located in the valve chamber. A bellows influences the valve body through a pressure sensitive rod in accordance with suction pressure. A solenoid includes a fixed iron core and a plunger arranged in a plunger chamber. The plunger urges the valve body through a solenoid rod by a force determined by the level of electric current supplied to the solenoid. The fixed iron core, which is located between the valve chamber and the plunger chamber, includes a guide hole for receiving the solenoid rod. An annular passage for connecting the valve chamber to the plunger chamber is formed between the guide hole and the solenoid rod. Accordingly, the pressure of the crank chamber is applied to the plunger chamber through the valve chamber and the annular passage. In this control valve, the valve body has desirable operating characteristics without relying on parts having precise dimensions.
