  • Fail safe mechanism for valve using a cock and lock return spring
    Patent number: 7665714
    Abstract: A fail safe mechanism having a return member, valve stem extension, energy storage member, and locking assembly. The valve stem extension is driven by an electrical actuator and configured to drive the return member in a first direction and to be driven by the return member in a second direction. The energy storage member is configured to store energy when the electrical actuator causes the valve stem extension to drive the return member in the first direction and to release the energy stored therein when a disruption of power causes the return member to drive the valve stem extension in the second direction. The locking assembly is configured to hold the return member in a cocked position such that the valve stem extension rotates with the valve independently of the return member and free of influence from the energy storage member while the power is applied to the electrical actuator.
