Abstract
In a paintball gun mechanism compressed air is admitted through passages (16) to the interior of the barrel (10) where it will move forward a hollow bolt (11) until it can escape through the bolt (11) to fire a paintball. The bolt (11) is then moved backward by compressed air in a chamber (15) until a central formation (12) of the bolt (11) enters a guide (13) to close a firing chamber (14) behind the bolt (11). The invention provides a valve member (17) independent of the bolt (11) which is biased by a spring (18) to close off the firing chamber (14) from the passages (16) except when displaced by the formation (12) of the bolt (11) during a final part of the rearward movement of the bolt (11).
