Abstract
(EN) Provided is a valve that can be closed with a small amount of driving force. This valve V1 comprises: a valve housing 10 in which a primary pressure port 41a and a secondary pressure port 11 are formed; a valve body 51 driven by a solenoid 80; a valve seat on which the valve body 51 is seated; and a spring 85 that urges the valve body in a valve opening direction, wherein the valve seat includes a first valve seat 10a and a second valve seat 40a which is disposed on an inner diameter side of the first valve seat 10a and moves in a direction in which the second valve seat approaches the valve body 51 due to a differential pressure between a primary pressure and a secondary pressure.
(FR) L'invention concerne une soupape qui peut être fermée à l'aide d'une petite quantité de force d'entraînement. Cette soupape (V1) comprend : un boîtier de soupape (10) dans lequel sont ménagés un orifice de pression primaire (41a) et un orifice de pression secondaire (11) ; un corps de soupape (51) qui est entraîné par un solénoïde (80) ; un siège de soupape sur lequel le corps de soupape (51) vient en appui ; et un ressort (85) qui pousse le corps de soupape dans une direction d'ouverture de soupape, le siège de soupape comprenant un premier siège de soupape (10a) et un second siège de soupape (40a) qui est disposé sur un côté diamètre interne du premier siège de soupape (10a) et se déplace dans une direction dans laquelle le second siège de soupape s'approche du corps de soupape (51) en raison d'une pression différentielle entre une pression primaire et une pression secondaire.
(JA) 小さい駆動力で閉弁することができる弁を提供する。 1次圧ポート41aおよび2次圧ポート11が形成されたバルブハウジング10と、ソレノイド80により駆動される弁体51と、弁体51が着座する弁座と、弁体51を開弁方向に付勢するスプリング85と、を備える弁V1であって、弁座は、第1弁座10aと、第1弁座10aの内径側に配置され1次圧と2次圧の差圧によって弁体51に近接する方向に移動する第2弁座40aとを備えている。
