摘要： 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.

摘要： A supply mechanism for gas projectile firing devices includes: a magazine having a storage column for projectiles and a transfer slide for moving projectiles from a column to a position in line with the firing chamber; a mobile element having a transfer bar for moving the transfer slide from the column to its position next to the firing chamber, an insertion piston for moving projectiles from the transfer slide into the firing chamber and a firing pin for opening the valve connecting the compressed gas reservoir to the firing chamber; a trigger which activates the firing and prevents double insertion of a projectile, and a cocking rod which controls the mobile element and the trigger. The mechanism is applicable to training and sports weapons, and to nail and staple guns.
