Abstract: The invention is directed to a valve actuating device comprising a body with a bore and a bottom, an actuating element sealingly housed in the bore of the body and forming a first chamber with the body, a piston sealingly extending through a bore in the actuating element, the piston and bore delimiting a second actuating chamber, a passage for an auxiliary fluid between the first and second chambers so that a movement of the piston in the bore of the actuating member can increase the pressure in the first chamber and move the actuating element. The fluid passage comprises a restriction and a check-valve, both arranged in parallel, so as to limit the flow of the auxiliary fluid from the second chamber to the first chamber.

Abstract: The invention is directed to a valve for a compressed gas cylinder, comprising: a valve body with an inlet, an outlet and a passage connecting the inlet with the outlet; a shut-off device of the passage with an actuating pin extending in the passage; a check-valve between the shut-off device and the inlet, the check valve comprising a seat and a movable closing member initially held at a position distant from the seat by contact with a guiding surface and movable past the position by the pin so as to cooperate with the seat and prevent a refilling flow of gas from the outlet to the inlet. The guiding surface is on a tubular portion fixed to the valve body and comprising at least one radial aperture so as to allow the refilling flow of gas to by-pass the closing member when in the distant position.

Abstract translation: 本发明涉及一种用于压缩气瓶的阀，包括：阀体，其具有入口，出口和连接入口与出口的通道; 所述通道的切断装置具有在所述通道中延伸的致动销; 截止装置和入口之间的止回阀，止回阀包括座和可移动的关闭构件，其最初通过与引导表面接触而保持在远离座位的位置，并可通过销移动通过该位置，以便 与座合作并防止气体从出口向入口再填充。 引导表面在固定到阀体上的管状部分上，并且包括至少一个径向孔，以便当处于远离位置时允许气体的再填充流动绕过封闭构件。
