Claims

[Scope of utility model registration request]

A pressure-responsive member is provided in a chamber formed by a housing and a cover that is open at one end, and an airtight pressure chamber in which pressure is controlled is formed on one side of the pressure-responsive member, and the pressure resists the biasing force of the return spring. In the actuator which obtains an action output by a first electromagnetic opening/closing means consisting of a valve body that opens and closes alternately, and first and second excitation coils that open and close the valve body; a valve body that opens and closes the second atmospheric port; and a valve body that opens and closes the valve body; and a second electromagnetic switching means consisting of an excitation coil, the first electromagnetic switching means
When both of the second excitation coils are energized, the pressure port is opened and the first atmospheric port is closed, and the first excitation coil of the first electromagnetic switching means is energized and controlled based on a control signal, An actuator characterized in that the second excitation coil of the first electromagnetic switching means and the excitation coil of the second electromagnetic switching means are wired and both are controlled to be energized based on a lease signal.
