SHUTTER FOR VALVE OF HIGH PRESSURE BOMBE

摘要

PURPOSE: A valve shutter of a high pressure gas tank is provided for the user to confirm the lock state with naked eyes by showing the lock state through a display device. CONSTITUTION: A valve shutter of a high pressure gas tank comprises a limited plate(80), a locking stopper(81), an opening stopper, and a proximity sensor(83). The limited plate is associated with the rotation of an output shaft of a first gear train. The locking stopper restricts the rotation of the limited plate to the locked state. The opening stopper restricts the rotation of the limited plate to the open state. The proximity sensor senses the locked state of the limited plate.
