SELF-CENTERING DUAL SHUTTLE AIR GUN

摘要

An air gun (10) for releasing compressed air into the environment. Two opposing shuttle valves (14, 16) selectively open ports (20) to release compressed air more quickly from the air gun. A centering mechanism returns the first (14) and second (16) shuttle valves to the initial position. The centering mechanism can comprise a pressure compensation system or mechanical stop for positioning the first and second shuttles at the selected position.
