Title
(EN) CAPACITY CONTROL VALVE
(FR) VANNE DE COMMANDE DE CAPACITÉ
(JA) 容量制御弁
Abstract
(EN) Provided is a capacity control valve capable of enhancing responsiveness. A capacity control valve V comprises: a valve housing 10 in which a suction port 11 through which a suction fluid of suction pressure Ps passes and a control port 12 through which a control fluid of control pressure Pc passes; a valve body 51 driven by a solenoid 80; a spring 85 urging the valve body 51 in a direction opposite to the drive direction by the solenoid 80; and a CS valve 50 that is configured of a CS valve seat 10a and the valve body 51 and opens and closes communication between the control port 12 and the suction port 11 by moving the valve body 51, the capacity control valve V controlling a control pressure Pc by opening and closing the CS valve 50, wherein the control fluid of control pressure Pc can be supplied to the back surface side of the valve body 51, and a flow path control means 40 is provided for reducing the pressure on the back surface side of the valve body 51 by using the fluid pressure generated by opening and closing the CS valve 50 and the pressure on the back surface side of the valve body 51.
(FR) Vanne de commande de capacité apte à améliorer la réactivité. Une vanne de commande de capacité (V) comprend : un boîtier de vanne (10) comprenant un orifice d'aspiration (11) à travers lequel passe un fluide d'aspiration à une pression d'aspiration (Ps) et un orifice de commande (12) à travers lequel passe un fluide de commande à une pression de commande (Pc) ; un corps de vanne (51) entraîné par un solénoïde (80) ; un ressort (85) poussant le corps de vanne (51) dans une direction opposée à la direction d'entraînement par le solénoïde (80) ; et une vanne CS (50) qui est constituée d'un siège de vanne CS (10a) et du corps de vanne (51), et qui ouvre et ferme une communication entre l'orifice de commande (12) et l'orifice d'aspiration (11) par un déplacement du corps de vanne (51), la vanne de commande de capacité (V) commandant une pression de commande (Pc) par une ouverture et une fermeture de la vanne CS (50), le fluide de commande à une pression de commande (Pc) pouvant être délivré au côté surface arrière du corps de vanne (51), et des moyens de commande de trajet d'écoulement (40) étant prévus pour réduire la pression sur le côté surface arrière du corps de vanne (51) à l'aide de la pression de fluide générée par une ouverture et une fermeture de la vanne CS (50) et de la pression sur le côté surface arrière du corps de vanne (51).
(JA) 応答性を高めることができる容量制御弁を提供する。 吸入圧力Psの吸入流体が通過する吸入ポート11および制御圧力Pcの制御流体が通過する制御ポート12が形成されたバルブハウジング10と、ソレノイド80により駆動される弁体51と、弁体51をソレノイド80による駆動方向と反対方向に付勢するスプリング85と、CS弁座10aと弁体51とにより構成され弁体51の移動により制御ポート12と吸入ポート11との連通を開閉するCS弁50と、を備え、CS弁50の開閉により制御圧力Pcの制御を行う容量制御弁Vであって、制御圧力Pcの制御流体を弁体51の背面側に供給可能となっており、CS弁50の開閉によって生じる流体圧と弁体51の背面側の圧力を利用して弁体51の背面側の圧力を低下させる流路制御手段40を備えている。
