Patent ID: 8640783

Claim:
An interlock coupled to a booster actuator, the actuator configured to operate with a low energy input and a high energy output using mechanically stored energy, the actuator including an actuator piston and a plunge piston coupled to the actuator piston, the interlock comprising: a housing defining a central orifice having a first end and a second end, the housing further defining an orthogonal orifice in communication with the central orifice, with the actuator coupled to the housing and with the actuator piston biased by a detent spring and plunge piston biased by a main spring disposed in and in communication with the first end of the central orifice; a spring guide disposed in the central orifice and coupled to the plunge piston, with the spring guide biased by an actuating spring, with the spring guide defining an interlock notch, wherein the ratio of mechanical stored energy in the detent spring, main spring, and actuating spring is 1:25:5 respectively; and a solenoid including a solenoid pin removably secured to the housing and aligned with the orthogonal orifice, with the solenoid pin engaged with the interlock notch, the solenoid configured to selectively disengage the solenoid pin from the interlock notch when energized to release the mechanically stored energy in the actuating spring to push the spring guide against the plunge piston which compresses the detent spring allowing the main spring energy to be released to push the actuator piston out of the booster actuator.
