turned off, an isolated spring inside the valve forces it open. The magnetic force of the solenoid coil must overcome the force of the spring to close the valve. Unless acted upon, the spring force keeps the valve open. In the event of a power failure, the valve will automatically open....
A valve actuator has an electric motor 50 driving a nut 20 on valve stem 18, via gear train 58-66 and a combined centrifugal clutch and torque-limiting device 56, to move the valve and compress spring 28. When a disc 36 on valve stem 18 abuts stationary shims 42, the torque limiting...
A fail-safe thermostat valve for controlling the flow of coolant to an engine has, in addition to a thermostat element that expands and contracts to open and close the valve, a fusible element that supports an elevated plate that holds two springs. One spring holds the valve plate in its ...
