Patent

CA 2161253

A bolt (141) having an opening formed therethrough is slidably located in the bore (52) of the gun. The bolt is held in a rear position by a sear (339) with the bolt opening closed by a valve (121) which extends into the bolt opening and engages a rear facing bolt seat (231). A passageway (125, 127) extends into the bolt opening by way of a valve for allowing pressurized gas to flow into the bolt opening. A trigger mechanism (309) releases the bolt for allowing the bolt to be moved forward for allowing the valve and seat to separate for allowing the gas to flow through the bolt opening for forcing a ball (59) from the rear end of the barrel out of the gun. A cock valve (421) located in a cock valve chamber (381) releases gas to force the bolt back to the rearward position.

Culasse (141) munie d'un trou traversant et reçue à coulissement dans l'âme (52) du pistolet. La culasse est maintenue en une position en retrait par une gâchette (339), le trou de la culasse étant obturé par une soupape (121) engagée dans ce trou et venant au contact d'un siège de culasse (231) tourné vers l'arrière. Un passage (125, 127) s'étend jusque dans le trou de la culasse par l'intermédiaire d'une soupape d'admission de gaz sous pression dans celui-ci. Un mécanisme à détente (309) libère la culasse afin de lui permettre d'avancer et de permettre ainsi à la soupape et au siège de s'écarter, ce qui permet au gaz de s'écouler par le trou de la culasse et d'expulser du pistolet un projectile provenant de l'extrémité arrière du canon. Une soupape de chien (421) située dans un chambre correspondante (381) libère le gaz pour ramener la culasse à la position en retrait.
