ABSTRACT:
A valve in the fuel line of an internal combustion engine of the type which is normally biased to its closed position, causing engine shut-down, but prevented by an opposing oil pressure from doing so; the valve, in effect, therefore being one which promotes engine shut-down in the event of failure in the engine oil pressure. As an improvement to this class of valves, of which the within valve is a significant contribution, the valve has an engine shut-down function related not merely to the required oil pressure at engine start-up, but also to required oil pressures at full power speed as well as intermediate power speeds throughout its contemplated range of operation.
