摘要： An engine protection valve to cut off flow of fuel to the engine when oil pressure drops below a predetermined level, comprising a piston 5 slidable in a bore 4 of a housing 2, the piston having a series of seals thereon which divide the bore into three chambers 20, 22, and 24. The chamber 20 has a fuel inlet 6 and a fuel outlet 7, and a valve seat 8 located between the fuel inlet and outlet. A restricted orifice 36 allows a restricted amount of fuel to pass from the chamber 20 to the chamber 22 thereby lubricating the bore 9 of chamber 22 and allowing the seal 16 to slide smoothly on the bore 9. The chamber 22 is kept at atmospheric pressure to enable the valve to operate and fuel to drain from the chamber 22 to the fuel tank through the conduit 40. An alternative arrangement is to lubricate the chamber 9 and seal 16 with engine oil from the chamber 24. The engine oil may be conveyed to the chamber 22 through a passage extending down the stem of the piston where after the oil drains from chamber 22 to a sump.

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.

摘要： An engine protective device that is reponsive to low oil pressure to cut off or limit fuel flow to avoid or minimize the chance of engine damage. A spring-biased elongate main valve member includes an axial bore and an override spring-biased ball valve to selectively allow fuel flow through said axial bore. A remote override function is realized by use of a bypass valve controlled by a pneumatic or electrical switch. An override lock prevents a mechanical, local (i.e., not remote) override from being changed from an override position back to a normal or off position in the event of insufficient oil pressure.

摘要： A control for preventing damage to an internal-combustion engine due to extended operation at excessive temperatures where the engine speed varies according to flow of fuel thereto. The control includes a fuel-limiting solenoid valve which controls the flow of fluid to the engine and which has a plunger movable from a first position permitting unobstructed fuel flow to a second position causing fuel flow reduction to a preset reduced amount causing engine speed reduction sufficient to reduce the operating temperature thereof, the valve having a winding which, when deenergized, permits movement of the plunger from the first position to the second position. Switch means is connected in a circuit with the winding for controlling the energization thereof and is responsive to the operating temperature of the engine. This switch means operates to cause deenergization of the winding when the engine operating temperature exceeds a preset level, thereby protectively reducing the engine speed to reduce its operating temperature.
