GAS PRESSURE TYPE ACTUATOR

摘要

Disclosed is a gas pressure actuator whose actuator body (26) has a cylinder (21), a piston (22) and a gas generator (25) in which a powder is loaded, and the gas generator (25) is positioned at an end portion of the cylinder (21). The gas generator (25) injects a high pressure gas into the cylinder (21) by the combustion of the powder, thereby moving the piston (22). The actuator body (26) is provided with a coating (30) which covers the entire actuator body (26) from outside. The coating (30) is a resin coating having electrically insulating, waterproof, and dustproof characteristics.
