As a result, the valve portion 521 comes into contact with the valve seat 513 and the passageway 150 is closed. This inhibits the flow of refrigerant from the passage outlet opening 182 to the passage inlet opening 181 in the passage passage 150 .

Abstract

Le problème décrit par la présente invention consiste à fournir un dispositif de soupape et un dispositif de climatisation avec lesquels une fuite d'un réfrigérant peut être supprimée et le nombre de composants peut être réduit. La solution selon l'invention porte sur un dispositif de soupape (10) qui présente un corps de soupape (100) présentant une pluralité de passages de réfrigérant et une pluralité d'unités de soupape montées sur le corps de soupape (100). La pluralité de passages de réfrigérant inclut un passage d'entrée (110) relié à une ouverture d'entrée (171) dans une surface avant (101) du corps de soupape (100), un passage de sortie (120) relié à une ouverture de sortie (172) dans une surface arrière (102) du corps de soupape (100), un passage d'expansion de réfrigérant (130) reliant le passage d'entrée (110) et le passage de sortie (120) et un passage de dérivation (140) reliant le passage d'entrée (110) et le passage de sortie (120). La pluralité d'unités de soupape inclut une unité de soupape d'expansion (200) apte à modifier la zone de passage du passage d'expansion de réfrigérant (130), une première unité de soupape d'ouverture/de fermeture (300) apte à ouvrir et à fermer le passage d'expansion de réfrigérant et une seconde unité de soupape d'ouverture/de fermeture (400) apte à ouvrir et à fermer le passage de dérivation (140).
