Abstract
An engine cooling system has a primary cooling circuit with a pump to circulate liquid coolant through an engine, the coolant being returned to the pump via a radiator and a bypass arranged in parallel. A temperature-responsive control valve controls flow as between said radiator and the bypass. The valve housing defines: a hot inlet connected to the bypass, a cold inlet connected to the radiator, and a valve chamber. The valve further includes a first valve member in the valve chamber movable between two limits to control the flow of coolant from the hot inlet to the outlet, a second valve member in the valve chamber movable between two limits to control coolant flow from the cold inlet to the outlet; and a temperature-responsive actuator to move the first and second valve members.
