摘要： Provided is a variable-capacity compressor control valve that can effectively reduce sliding resistance while preventing Pd-Ps leakage and the inclination of a valve element, thus increasing controllability and operation stability, and can also avoid operation failures or troubles caused by foreign matter. A sliding portion 15e of a main valve element 15 that is slidaly fitted and inserted into a guide hole 19 provided in a valve body 20 includes an upper small-clearance portion 61 and a lower small-clearance portion 62 in the opposite ends in a vertical direction thereof and a large-clearance portion 71 between the upper small-clearance portion 61 and the lower small-clearance portion 62. The upper small-clearance portion 61 and the lower small-clearance portion 62 each has a diameter Dx and a vertical length that is equal to or larger than a predetermined length. The large-clearance portion 71 has a diameter Dy that is smaller than the Dx and a vertical length of 1 mm or larger.

摘要： Provided is a variable-capacity compressor control valve with a simple configuration that can secure the size of a sub valve element portion of a sub valve element, which is adapted to open or close an in-valve release passage, and can improve the actuation property and reduce the size of the control valve. The sub valve element (17) is integrated with the plunger (37) for moving the main valve element (15) in the direction to open or close a valve orifice so that the sub valve element (17) always moves together with the plunger (37). The sub valve element (17) is securely inserted in the plunger (37).

摘要： Provided is a variable-capacity compressor control valve where the size of a plunger can be reduced, the machining and assembly process can be simplified, weight reduction can be achieved, and cost reduction can also be achieved, for example. The plunger has a slit through which a valve element is assembled to the plunger by being inserted from a lateral side. The slit serves as a flow path for releasing the pressure Pc in the crank chamber to the suction chamber of the compressor from the Ps inlet/outlet port when the sub valve element has opened the in-valve release passage.

摘要： Provided is a variable-capacity compressor control valve that can effectively suppress an increase in the sliding resistance and deterioration of the control properties associated therewith while avoiding intrusion of foreign matter into a sliding-surface gap (i.e., clearance) formed between a main valve element and a guide hole. Also provided is a variable-capacity compressor control valve that can have stable sealing properties irrespective of the dimension errors of the parts forming the valve. A plate-like ring member 20E for sealing the gap between the valve chamber 21 and the pressure-sensitive chamber 45 is disposed between the guide hole 19 and the main valve element 10 with the inner end of the plate-like ring member 20E being curved and shaped into a tubular shape and thus forming a tubular portion 20Eb, the tubular portion 20Eb being adapted to be in sliding contact with the outer wall of the main valve element 10.

摘要： Provided is a variable-capacity compressor control valve where a valve body can be easily machined and the machining time and machining cost can be reduced without a decrease in the valve closing property or a decrease in the slidability of the valve element due to shaft misalignment. The valve body includes a support member having formed therein a valve orifice and a guide hole into which the valve element is adapted to be slidably fitted and inserted; and a body member having formed therein a Ps inlet/outlet port, a Pd introduction port, and a Pc inlet/outlet port. The support member is fixedly inserted into a recess hole provided in the body member. In addition, a chip sealing portion (pocket portion) for sealing chips of the body member and/or the support member is provided between the body member and the support member.
