Abstract : A liquid propellant gun featuring concentric propellant pump, valve and bolt. Forward movement of the bolt causes forward movement of the propellant pump by interconnection of ball detents. The valve is forced open by differential pressure and closed by abutment of pump surfaces. At this juncture the ball detent connection is relieved and the bolt continues forward to pressurize the propellant charge before firing. (Author)
