Abstract
(EN) Provided is a capacity control valve which is capable of operating efficiently while having a fluid discharge function at startup. A capacity control valve V comprising: a valve housing 10 that has formed therein a discharge port 12, intake ports 13, 15, and a control port 14; and a main valve 50 formed of a main valve body 51 which is driven by a solenoid 80 and a main valve seat 10a which is provided between the discharge port 12 and the control port 14 and with which the main valve body 51 is capable of coming into contact, wherein the capacity control valve is provided with a CS valve 57 which has a CS valve body 56 having a communication hole 56f formed therein and being configured to slidably move on the valve housing 10 in conjunction with the main valve body 51, and in which the communication hole 56f makes it possible for a flow channel between the control port 14 and the intake port 15 to establish connection in accordance with the slide position of the CS valve body 56.
(FR) L'invention concerne une soupape de régulation de capacité qui est apte à fonctionner efficacement tout en présentant une fonction d'évacuation de fluide au démarrage. Une soupape de régulation de capacité (V) comprend : un logement de soupape (10) qui présente, formé en son sein, un orifice d'évacuation (12), des orifices d'admission (13, 15) et un orifice de régulation (14) ; et une soupape principale (50) formée d'un corps de soupape principal (51) qui est entraîné par un solénoïde (80) et d'un siège de soupape principal (10a) qui est disposé entre l'orifice d'évacuation (12) et l'orifice de régulation (14) et avec lequel le corps de soupape principal (51) est apte à venir en contact, la soupape de régulation de capacité étant dotée d'une soupape CS (57) qui présente un corps de soupape CS (56) présentant un trou de communication (56f) formé en son sein et étant configurée pour se déplacer de façon coulissante sur le logement de soupape (10) conjointement avec le corps de soupape principal (51), et le trou de communication (56f) permettant à un canal d'écoulement entre l'orifice de régulation (14) et l'orifice d'admission (15) d'établir un raccordement conformément à la position de coulissement du corps de soupape CS (56).
(JA) 起動時の流体排出機能を有しつつ運転効率が良い容量制御弁を提供する。 吐出ポート12、吸入ポート13,15および制御ポート14が形成されたバルブハウジング10と、ソレノイド80により駆動される主弁体51、および吐出ポート12と制御ポート14との間に設けられ主弁体51が接触可能な主弁座10aにより構成される主弁50と、を備える容量制御弁Vであって、連通孔56fが形成され、主弁体51と連動しバルブハウジング10にスライド摺動するCS弁体56を有し、CS弁体56のスライド位置に応じて連通孔56fが制御ポート14と吸入ポート15間の流路を連通可能とするCS弁57を備えている。
