Title
(EN) FLOW PATH SWITCHING VALVE
(FR) SOUPAPE DE COMMUTATION DE TRAJET D'ÉCOULEMENT
(JA) 流路切換弁
Abstract
(EN)
A flow path switching valve is provided which, by decreasing the pressure load and avoiding deformation of a high pressure-side slide-type valve body, can suppress seal surface distortion and prevent valve leakage, and which improves efficiency of a heat pump-type heating and cooling system. In this flow path switching valve (1), a low pressure-side slide valve body (15B) fits slidably on the outside of a cylindrical high pressure-side slide valve body (15A). Between the high pressure-side slide valve body (15A) and the low pressure-side slide valve body (15B), an O ring (18) is provided which is an annular seal member.

L'invention concerne une soupape de commutation de trajet d'écoulement qui, en diminuant la charge de pression et en évitant la déformation d'un corps de soupape de type coulissant côté haute pression, peut supprimer une distorsion de surface d'étanchéité et empêcher une fuite de soupape, et qui améliore l'efficacité d'un système de chauffage et de refroidissement de type pompe à chaleur. Dans cette soupape de commutation de trajet d'écoulement (1), un corps de soupape coulissant côté basse pression (15B) s'ajuste de manière coulissante sur l'extérieur d'un corps de soupape coulissant côté haute pression (15A) cylindrique. Entre le corps de soupape coulissant côté haute pression (15A) et le corps de soupape coulissant côté basse pression (15B), un joint torique (18), qui est un élément d'étanchéité annulaire, est prévu.

圧力荷重を小さくして高圧側スライド式弁体の変形を回避することにより、シール面の歪みを抑えて弁漏れを防ぐことができ、ヒートポンプ式冷暖房システムの効率向上を図った流路切換弁を提供する。 流路切換弁(1)では、筒状の高圧側スライド弁体(15A)の外側に、低圧側スライド弁体(15B)を摺動自在に嵌合する。高圧側スライド弁体(15A)と低圧側スライド弁体(15B)との間に、環状のシール部材であるOリング(18)を設ける。
