SELF-LOADING GRENADE LAUNCHER

摘要

The invention relates to a self-loading grenade launcher with a cartridge belt feed device which conveys a cartridge by means of pawls engaging in the cartridge belt preferably horizontally to the front of a cartridge chamber, in which the pawls are borne by two counteracting slides movable transversely to the direction of fire and arranged in a hinged cover and project downwards. An inertia bolt runs forward along a path from a release position against the cartridge chamber under the force of one or preferably two return springs and is fitted so as to slide the cartridge conveyed from the cartridge belt by the pawls into the cartridge chamber during this forward movement and, owing to the recoil force due to the firing of the cartridge, to run back along the path and thereby retensioning the return spring(s). A control system coupled to the inertiabolt and the slides converts the forward and recoil movement of the bolt into the transverse alternating movement of the slides. A firing device comprises a firing pin which is tensioned by a percussion spring and held by a detent in the tensioned state, whereby the detent is released and the cartridge fired before the inertia bolt has completed its forward travel but only after the cartridge has penetrated far enough into the cartridge chamber to hold the gas pressure resulting from firing. A housing secured to the cartridge chamber extends along the bolt path and partially surrounds it, the longitudinal axis of which continues the central axis of the cartridge chamber.
