Abstract (en)
[origin: EP0332226A2] The gun structure comprises a breech casing (21) defining a breech bore, a fixed member (5) in the breech bore, a differential area piston (6) dividing the breech bore between a combustion chamber (55) and a propellant reservoir (35), said piston having an enlarged portion and a cut out portion, said cut out portion overrunning the fixed member as piston moves from a gun charged position to a gun discharged position, and said cut out portion and said enlarged portion being so sized and shaped to cooperate as said piston moves with respect to said fixed member to define a variable area injection orifice for the flow of propellant from said reservoir to said combustion chamber.
