摘要： An inherently fail-safe automatic remote-control and engine protection device of electromechanical/hydraulic assembly is supplied by engine lube oil and controlled by circuitry, acting on an existing non-included throttle or governor, especially in diesel generator standby applications, so as to enhance utility, engine reliability and longevity, all without engine modification. This assembly is a linear actuator, of few parts and no levers, basically comprised of a pull solenoid and a spring-return hydraulic cylinder contained within a guide tube which is held stationary. The solenoid armature is indirectly attached to one end of a cable and the engine governor is linked to the other end. The hydraulic cylinder's rod is rigidly attached to an actuator tube which is a sliding sleeve to the guide tube. The actuator tube itself is coupled to the cable such as to allow independent operation of said cable by solenoid, cylinder, or both.

摘要： An electromechanical/hydraulic assembly controlled by circuit board, acting on an engine throttle so as to allow for remote control and engine fault protection. An idle solenoid pushes and slides a captive throttle rod through a linear translation bracket so as to move engine throttle to idle position for fixed time upon starting. Engine oil pressure flows through a controlled check valve in reduced flow direction into a solenoid valve and then into a hydraulic cylinder to gradually advance indirectly attached throttle to operating position. Hydraulic cylinder, through pivoted lever, actuates a switch at proper engine speed so as to connect generator load. Upon pushing off button, load is disconnected. Solenoid valve de-energizes blocking oil flow into hydraulic cylinder and allows cylinder to retract under spring pressure by exhausting cylinder into engine sump through drain circuit of solenoid valve. Throttle will then return to "idle" or "off" depending on idle solenoid mode as determined by stand-by mode switch position. Oil pressure failure will shut down engine by emptying hydraulic cylinder regardless of sensor circuit failure or other component mode. A sensed failure in properly operating system, turns off solenoid valve and provides sump path from hydraulic cylinder. Controlled check valve will release oil back to engine upon oil pressure failure to engine if solenoid valve, for whatever reason, does not return to "off" position.
