Fail-safe oil flow control apparatus

摘要

Fail-safe oil flow control apparatus of this invention includes a thermally responsive actuator for operation of a valve member to control oil flow through a heat exchanger in accordance with the oil temperature conditions which exist. The apparatus also includes resilient members which operate to control operation of the valve member in accordance with the oil pressure conditions which exist. The apparatus also includes a fusible body which melts and permits operation of the valve member when excessive temperatures exist in the apparatus.
