Abstract
(EN)
A flow path switching valve is provided which, by increasing the rigidity of a high pressure-side valve body of a slide 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), on the opposite inner peripheral surfaces of a high pressure-side slide valve body (15A), a bridging part (19) is provided which connects the inner peripheral surfaces which face each other in the direction perpendicular to the axial direction of a main valve chamber (12). For that reason, it is possible to increase rigidity of the high pressure-side slide valve body (15A), and seal surface distortion can be suppressed even if a high pressure refrigerant flows and applies a high pressure to the high pressure-side slide valve body (15A). Consequently, it is possible to suppress valve leakage in the flow path switching valve (1), and further, increased efficiency of the heat pump-type heating and cooling system (100) is achieved.

L'invention concerne une soupape de commutation de trajet d'écoulement qui, en augmentant la rigidité d'un corps de soupape côté haute pression d'un corps de soupape coulissant, 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), sur les surfaces périphériques internes opposées d'un corps de soupape coulissant côté haute pression (15A), une partie de pontage (19) est prévue, qui relie les surfaces périphériques internes qui se font face dans la direction perpendiculaire à la direction axiale d'une chambre de soupape principale (12). Pour cette raison, il est possible d'augmenter la rigidité du corps de soupape coulissant côté haute pression (15A), et une distorsion de surface d'étanchéité peut être supprimée même si un fluide frigorigène haute pression s'écoule et applique une pression élevée au corps de soupape coulissant côté haute pression (15A). Par conséquent, il est possible de supprimer une fuite de soupape dans la soupape de commutation de trajet d'écoulement (1) et, en outre, une efficacité accrue du système de chauffage et de refroidissement de type pompe à chaleur (100) est obtenue.

スライド式弁体の高圧側弁体の剛性を高めることにより、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、高圧側スライド弁体(15A)の対向する内周面には、主弁室(12)の軸線方向に直交する方向に向き合う内周面同士を繋ぐかけ渡し部(19)が設けられている。そのため、高圧側スライド弁体(15A)の剛性を高めることができ、高圧の冷媒が流れて高圧側スライド弁体(15A)に高い圧力がかかっても、シール面の歪みを抑えることができる。従って、流路切換弁(1)での弁漏れを抑止することができ、ヒートポンプ式冷暖房システム(100)の更なる効率向上が実現する。
