ABSTRACT:
A liquid propellant gun utilizes a differential piston having a plurality of bores through its head, which head divides the liquid propellant pumping chamber from the combustion chamber, and propellant supply means providing liquid propellant under pressure into said pumping chamber, which propellant under pressure both advances the piston to enlarge the pumping chamber and to decrease the combustion chamber and injects and atomizes a predetermined quantity of propellant through said bores from said pumping chamber into said combustion chamber, and a check valve which precludes flow of liquid propellant under pressure from said piston to said propellant supply means and damps said piston at the end of its combustion stroke by means of a damping cylinder.
