ABSTRACT:
In a cartridge casing there is provided a telescopic valve stem having at its forward end a main outlet valve and at its rearward end a servo- or pressure relief valve, a piston-like collar on the forward part of the valve stem divides the interior of the casing into a forward main chamber and a rearward auxiliary chamber; the chambers are connected by a bleeding passage and have an outlet opening at the forward end and the rearward end of the casing respectively, which openings are normally closed by the respective valves. A chamber of variable volume within the telescopic valve stem is in communication with the atmosphere, due to which the rearward or servo-valve may be opened by a slight fire pin blow to initiate the discharge of pressurized gas filling from the main chamber.
