Title (EN) LOW-COST ONE-WAY VALVE DEVICE
(FR) DISPOSITIF SOUPAPE ANTIRETOUR À FAIBLE COÛT
(KO) 저가형 일방향 밸브 장치
Abstract:
(EN) The present invention relates to a low-cost one-way valve device which transports a refrigerant in one direction such as the direction of a condenser and enables preventing the backflow of the refrigerant. The low-cost one-way valve device may comprise: a valve case which has a cylindrical form having an opened lower part, has at least one fluid outlet formed along the outer circumferential surface thereof, and has a fluid inlet, through which fluid enters, formed on the lower part; a valve core for selectively opening/closing the fluid inlet and the fluid outlet; an elastic member for applying elastic restoring force to the valve core in the direction in which the fluid inlet is closed; and an elastic stopping part which is protrudingly formed in the inner direction of the valve case.
(FR) L'invention concerne un dispositif soupape antiretour à faible coût, qui transporte un réfrigérant dans une direction telle que la direction d'un condenseur, et empêche le reflux du réfrigérant. Le dispositif soupape antiretour à faible coût peut comprendre: un boîtier de soupape de forme cylindrique présentant une partie inférieure ouverte, et comportant au moins une sortie de fluide formée le long de sa surface circonférentielle externe, et une entrée de fluide formée sur la partie inférieure et par laquelle pénètre un fluide; un obus de soupape pour ouvrir/fermer sélectivement l'entrée de fluide et la sortie de fluide; un élément élastique pour appliquer une force de rappel élastique au noyau de soupape dans la direction dans laquelle l'entrée de fluide est fermée; et une pièce d'arrêt élastique formée en saillie dans la direction interne du boîtier de soupape.
(KO) 본 발명은 냉매를 응축기 방향 등 일방향으로 이송하고, 냉매의 역류를 방지할 수 있게 하는 저가형 일방향 밸브 장치에 관한 것으로서, 하부가 개방된 원통형상으로 형성되어 외주면을 따라 적어도 한개 이상의 유체 배출구가 형성되고, 상기 하부에 유체가 유입되는 유체 유입구가 형성되는 밸브 케이스와, 상기 유체 유입구 및 상기 유체 배출구를 선택적으로 개폐시키는 밸브 코어와, 상기 유체 유입구를 폐쇄하는 방향으로 상기 밸브 코어에 탄성 복원력을 인가하는 탄성 부재 및 상기 밸브 케이스의 내측방향으로 돌출되게 형성되는 탄성 걸림부를 포함할 수 있다.
