GAS PRESSURE TYPE ACTUATOR

摘要

An actuator body (26) has a cylinder (21), a piston (22), and a gas generator (25) filled with powder. The gas generator (25) is placed at an end of the cylinder (21). Combustion of the powder causes the gas generator (25) to eject high pressure gas in the cylinder (21) to move the piston (22). A coating (30) externally covers the entire part of the actuator body (26). The coating (30) is a resin coating having electric insulation, waterproof, and dust proof properties.
