Fail-safe oil flow control apparatus.

摘要

Fail-safe oil flow control apparatus includes a thermally responsive actuator (24) operable to displace a tubular valve member (70) so as to control lubricating oil so that it flows either directly to an engine, or to the engine through an oil cooler, in accordance with the oil temperature conditions which exist. The apparatus also includes a spring (40) which controls operation of the valve member (70) in accordance with the oil pressure conditions which exist. The apparatus also includes a fusible body (50) which melts and permits operation of the valve member when excessive temperatures exist in the apparatus.
