Title (EN) A VALVE FOR PROVIDING A GAS PULSE
(FR) SOUPAPE CREANT DES IMPULSIONS DE GAZ
Abstract: front page image
(EN)A valve for a gas, comprising a housing (1,2) provided with an inlet opening (3) and an outlet opening (4) and a movable valve member (5) which can bear against a valve seat (6) for the purpose of closing the valve, with a control chamber (25) being formed on the side of the movable valve member remote from the valve seat, which control chamber comprises the stroke volume of the valve and which is connected, via a throttle channel (10) , to the inlet opening, a vent passage (26) between the control chamber and the outlet opening, a control valve (28) that is capable of closing and opening the vent passage in a controlled manner so as to allow gas to escape from the control chamber to the outlet opening, such that the pressure on the part of the other side of the movable valve member, which is in open communication with the inlet opening, moves the movable valve member away from the valve seat and opens the valve, wherein the vent passage extends beyond the valve seat in the outlet opening in the open position of the valve member, with a non- return valve being provided in or near vent passage, which non-return valve is capable of closing the vent passage so as to prevent gas flowing from the outlet opening to the control chamber in said open position of the valve member.
(FR)L'invention porte sur une soupape à gaz comportant: un corps muni d'un orifice d'entrée et d'un orifice de sortie; un élément mobile placé dans le corps, pouvant porter sur le siège de la soupape pour la fermer, et comprenant une chambre de commande latérale distante du siège de soupape, du volume de la course de la soupape, et reliée via un étranglement à l'orifice d'entrée; un évent reliant la chambre de commande à l'orifice de sortie; une soupape de commande ouvrant ou fermant l'évent pour permettre ou interdire au gaz de la chambre de commande de sortir par l'évent. La pression s'exercent sur la partie de l'autre côté de l'élément mobile de la soupape communiquant avec l'orifice d'entrée écarte l'élément mobile du siège de la soupape et ouvre la soupape. L'évent s'étend alors au delà du siège de la soupape dans l'orifice de sortie et un clapet prévu dans ou à proximité de l'évent peut le fermer, ce qui empêche le gaz de s'écouler par l'orifice de sortie vers la chambre de commande alors que la soupape est ouverte.
