A gas valve comprising a valve body which is capable of butting against a valve seat so as to close the gas valve. The valve body comprises a membrane which is fixed in the valve housing at its outside edge, in such a manner that a control chamber is formed at the side remote from the valve seat, which control chamber is connected to the gas inlet via a throttle channel. At least part of the other side of the membrane is in communication with the gas inlet, and means are provided for allowing gas to escape from the control chamber so as to open the gas valve, in that the gas pressure from the gas inlet on said other side causes the valve body to move away from the valve seat. The valve body comprises a valve member which is centrally attached to the membrane and which is substantially positioned on said other side of the membrane, which valve member sealingly mates with the valve seat.
Soupape de gaz comportant un corps de soupape apte à venir buter contre un siège de soupape afin de fermer la soupape de gaz. Le corps de soupape comporte une membrane fixée par son bord externe à l'intérieur du corps de soupape, de telle sorte qu'une chambre de commande soit formée du côté éloigné du siège de soupape, cette chambre de commande étant reliée à l'arrivée de gaz par l'intermédiaire d'un conduit à étranglement. Au moins une partie de l'autre côté de la membrane est mise en communication avec l'arrivée de gaz, et on a prévu des moyens pour permettre au gaz de s'échapper de la chambre de commande de manière à ouvrir la soupape de gaz, étant donné que la pression du gaz provenant de l'arrivée de gaz dudit autre côté oblige le corps de soupape de s'écarter du siège de soupape. Le corps de soupape comporte un élément de soupape fixé au centre de la membrane et sensiblement situé dudit autre côté de la membrane, ledit élément de soupape venant se placer en contact étanche avec le siège de soupape.
