Title (EN) PILOT CHECK VALVE
(FR) SOUPAPE PILOTE DE NON-RETOUR
(JA) パイロットチェック弁
Abstract:
(EN) A pilot check valve (10) according to the present invention comprises: a fluid channel body (16); a moveable body (85) that moves in an axial direction under the effects of pilot pressure; a packing (20) comprising a lip portion (62) that is displaceable, integrally with the moveable body (85), between a valve close position and a valve open position; and a detector (25) for detecting the position of the moveable body (85). The packing (20), in the valve close position, allows the flow of an operating liquid from a first port (12) side of the fluid channel body (16) to a second port (14) side and prevents the flow of the operating liquid from the second port (14) side to the first port (12) side, andin the valve open position, connects the first port (12) and the second port (14).
(FR) La soupape pilote de non-retour (10) de l'invention est équipée : d'un corps de trajet d'écoulement (16) ; d'un organe mobile (85) qui fonctionne dans la direction axiale sous l'action d'une pression pilote ; d'une garniture (20) qui possède une partie lèvre (62) capable de se déplacer entre une position ouverture de soupape et une position fermeture de soupape d'un seul tenant avec l'organe mobile (85) ; et d'un détecteur (25) détectant la position de l'organe mobile (85). La garniture (20) autorise l'écoulement d'un fluide de travail depuis le côté d'un premier orifice (12) du corps de trajet d'écoulement (16) vers le côté du second orifice (14), en position fermeture de soupape, et simultanément interdit l'écoulement du fluide de travail du côté du second orifice (14) vers le côté du premier orifice (12), et met le premier orifice (12) et le second orifice (14) en communication en position ouverture de soupape.
(JA)  パイロットチェック弁(10)は、流路ボディ(16)と、パイロット圧の作用下に軸方向に動作する可動体(85)と、可動体(85)と一体的に弁閉位置と弁開位置との間を変位可能なリップ部(62)を有するパッキン(20)と、可動体(85)の位置を検出する検出器(25)とを備える。パッキン(20)は、弁閉位置において、流路ボディ(16)の第1ポート(12)側から第2ポート(14)側への作動流体の流れを許容するとともに、第2ポート(14)側から第1ポート(12)側への作動流体の流れを阻止し、弁開位置において、第1ポート(12)と第2ポート(14)とを連通させる。
