Abstract
An improved oil cooling system for internal combustion engines includes a pressure relief block which replaces the standard oil cooler of the engine, and a finned radiator depending from the engine sump plate in the passing air stream. The oil is pumped through the engine to the pressure relief block, where it passes a high pressure relief valve and is diverted through the hoses to the finned radiator. The cooled oil leaves the radiator, passes through a low pressure relief valve, and returns to the sump. The entire system may be bolted onto an existing engine with no modification to the engine required, to provide greatly increased oil cooling capacity. Further, the entire or substantially the entire oil flow must pass through the cooling system prior to passage through any pressure relief valves or the like.
Claims8
An improved lubricating cooling system for an engine including a source of pressurized oil and a sump, wherein the improvement comprises:
- a heat exchanger disposed externally to the engine and provided with an input side connected to the source of pressurized oil and an output side, first pressure relief valve means connected between said input side and said output side of the heat exchanger for bypassing said heat exchanger only at oil pressures above a first fixed value, a supply line connecting said output side of said heat exchanger and the downstream side of said valve means to the lubricating points of the engine, and second pressure relief valve means connected between and heat exchanger output side and the oil sump for bypassing the lubricating points of the engine only at pressures above a second fixed value.
