ABSTRACT:
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.
