Abstract
(EN)
Provided is a pilot valve that is for reliably moving a switching valve of a gas operation valve. This pilot valve 80 is provided with: a valve main body 84 that is a bottomed-cylinder that has an opening 81d at one end; spools 85, 87 that are slidably housed inside the valve main body 84; and flexible bodies 86, 88 that are arranged on an other-end side of the spools 85, 87, which is the side opposite an opening 81d side, and that urge the spools 85, 87 toward the opening 81d side. The valve main body 84 has at least three through hole parts 81a that are provided at approximately uniform intervals in the length direction. The spools 85, 87 allow at least two adjacent through hole parts 81a of the valve main body 84 to communicate. The elastic bodies 86, 88 and a pressing means cooperate to press the spools 85, 87 toward the opening 81d side, and, as a result, the spools 85, 87 go from being positioned on the side opposite the opening 81d side to being positioned on the opening 81d side.

L'invention concerne une vanne pilote qui permet de déplacer de manière fiable une vanne de commutation d'une vanne d'activités gazières. Cette vanne pilote (80) comporte : un corps principal de vanne (84) qui est un cylindre avec fond qui possède une ouverture (81d) à une extrémité ; des bobines (85, 87) qui sont logées de manière coulissante à l’intérieur du corps principal de vanne (84) ; et des corps flexibles (86, 88) qui sont disposés sur un côté d'autre extrémité des bobines (85, 87), qui est le côté opposé au côté de l'ouverture (81d), et qui sollicitent les bobines (85, 87) en direction du côté de l'ouverture (81d). Le corps principal de vanne (84) possède au moins trois parties de trou traversant (81a) qui sont prévues à des intervalles approximativement réguliers dans le sens de la longueur. Les bobines (85, 87) permettent à au moins deux parties de trou traversant adjacentes (81a) du corps principal de vanne (84) de communiquer. Les corps élastiques (86, 88) et un moyen de pression coopèrent pour presser les bobines (85, 87) en direction du côté de l'ouverture (81d) et, par conséquent, les bobines (85, 87) passent d'un positionnement sur le côté opposé au côté de l'ouverture (81d) à un positionnement sur le côté de l'ouverture (81d).
