ABSTRACT:
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.
