Title:
施条シリンダを有する火工アクチュエータ装置
Document Type and Number:
Japanese Patent JP3980555
Kind Code:
B2
Abstract:
A energetic-based piston actuator system imparts a rotational motion in the piston in a manner that increases system efficiency and reliability. A malleable ring mounted about the piston neck obturates upon initiation of the energetic charge, and rifling provided on an interior surface of the actuator barrel causes the ring to rotate, and causes a counter-rotation in the piston. The rotating ring serves as a seal for preventing gas blow-by and the rotating piston is more dynamically stable throughout its travel down the barrel.
