Abstract

The invention relates to a device for feeding with compressed gas a weapon of the type including a gas reserve, a valve that can move inside a valve housing and a valve seat located in this housing, holding and guiding a valve rod. This device includes an expansion unit interposed between the gas reserve and the valve, consisting of a first expansion chamber communicating with the gas reserve and a second chamber, the chambers being separated by a calibrated orifice. The volume of the second chamber is smaller than that of the first chamber. Both chambers are delimited by hollow cylindrical elements, the cylinder which constitutes the second chamber projecting into the valve housing, its end constituting the valve stop so that the distance between the stop of the seat and the valve stop determines the valve stroke. The motive power that closes the valve consists of the reaction force generated by the impact of the valve against the stop, on the one hand, and of the compressed gas pressure, on the other hand.
