Abstract
A choke-type thermostat is provided with a bypass valve. The inventive thermostat has a pliable valve member which prevents flow to an engine coolant bypass when the thermostat is in the completely open position in regards to an engine radiator outlet. Valving of the engine coolant bypass provides maximum flow to the radiator outlet when the thermostat is in the open position. Since the engine bypass is valved off by the thermostat when the thermostat is in the open position the diameter of the engine coolant bypass may be increased therefore allowing increased flow therethrough when the thermostat is in a closed position.
