Title (EN) PILOT SOLENOID VALVE
(FR) ÉLECTROVANNE PILOTE
(JA) パイロット式電磁弁
Abstract:
(EN) Provided is a pilot solenoid valve capable of bringing the strokes of a plunger to a necessary minimum and capable of achieving solenoid valve miniaturization and power saving. A pilot solenoid valve (1) is provided with a diaphragm section, a primary side section, a secondary side section, a main valve (60), a back pressure chamber (31), a primary side auxiliary flow path, a secondary side auxiliary flow path, an auxiliary valve (45), and an auxiliary valve drive unit, wherein the secondary side auxiliary flow path (113) is not formed in the main valve (60) but rather is formed in the area around the main valve (60) so as to bypass the main valve (60).
(FR) L'invention concerne une électrovanne pilote permettant de raccourcir les courses d'un plongeur à un minimum nécessaire et permettant d'obtenir une miniaturisation de l'électrovanne et une économie d'énergie. L'électrovanne pilote (1) comprend une section de diaphragme, une section latérale primaire, une section latérale secondaire, une soupape principale (60), une chambre de contre-pression (31), un circuit d'écoulement auxiliaire latéral primaire, un circuit d'écoulement auxiliaire latéral secondaire, une soupape auxiliaire (45) et une unité d'entraînement de soupape auxiliaire. Le circuit d'écoulement auxiliaire latéral secondaire (113) n'est pas formé dans la soupape principale (60) mais plutôt dans la zone située autour de la soupape principale (60) de façon à contourner la soupape principale (60).
(JA) プランジャーのストロークを必要最小限とすることが可能であり、電磁弁の小型化や省電力化を図ることが可能なパイロット式電磁弁を提供する。ダイアフラム部と、一次側部と、二次側部と、主弁(60)と、背圧室(31)と、一次側副流路と、二次側副流路と、副弁(45)と、副弁駆動部と、を備え、二次側副流路(113)は、主弁(60)に形成されておらず、主弁(60)の周囲に主弁(60)を迂回するように形成されているパイロット式電磁弁(1)である。
