Oil flow control for IC engine

摘要

The oil flow control for an ic-engine has a housing (10) within the oil duct system. A valve (70) within the housing controls flow between an inlet passage (86) from the pump and passages (94,90) leading to the oil cooler and engine respectively. A movable wall (66) exposed to pressure in the inlet passage (86) controls movement of the valve member. - A thermally responsive actuator (24) is connected to the valve for movement of the latter in accordance with oil temperature. A spring (40) within the housing biases the valve member w.r.t. the seat, and is normally retracted from the seat by a heat fusible plug.
