Abstract

A system for protecting an internal combustion engine from damage in the event of a malfunction in the engine cooling system includes a coolant flow pressure controlled valve interposed in the oil line leading from an oil pressure actuated fuel control device back to the engine sump. When the engine is operating, the valve is normally maintained closed by the flow pressure in the cooling system. However, when the coolant flow pressure drops below a predetermined value due to a malfunction such as a break in a radiator hose, a leak in some other element of the cooling system, a faulty water pump or a slipping or broken fan belt, the valve is automatically opened by spring pressure to release the oil pressure at the valve and permit the oil to flow into the dump line to the sump. The resulting drop in oil pressure at the fuel control device enables the device to shut off the supply of fuel to the engine. The coolant flow pressure controlled valve is connected into the oil line in parallel with another normally closed temperature responsive valve which is opened when the temperature of the coolant rises above aa predetermined value.
