<p>For a shell thrower the grenade is inserted in a barrel and a booster charge under the grenade will fire and generate a gas pressure which forces the grenade out of the barrel. In order to improve the driving charge acting on the grenade it is hereby proposed that a pressure plate (1) is detachably fixed under the grenade (2), and that the booster charge (3) is located on the underneath side of the pressure plate (1). An ignition mechanism for the booster charge (3) is arranged on the underneath side of the pressure plate, which ignition mechanism (4) is initiated by the impact of the pressure plate (1) against the bottom or a shoulder of the barrel. A releasable engagement (5) is arranged between the upper side of the pressure plate and the bottom of the grenade, which engagement includes a locking means, which is released from its locking position by means of a part of the driving pressure of the booster charge.</p> |
