A GUN

摘要

A gun (10) having a body (11) with a barrel (14) extending through it is disclosed. A nozzle (50) is coupled to one end of the barrel (14) and to which a hose may be connected. A valve (52) is connected to an opposite end of the barrel (14) and a sleeve (18) with circumferentially space substantially longitudinally extending passages (21) is present within the barrel (14) and compressed air may be introduced into the barrel (14) and caused to flow through the spaced passages (21) such that when the valve (52) is open the flow of compressed air causes fluid to flow through the barrel (14).
