Abstract

A thermostatic valve assembly for an engine cooling system has an inlet port 50, an outlet port 52 and at least one moveable sealing element 60, 62 for selectively closing or opening a pathway of coolant circulating in the engine, and is characterized by at least a first and a second thermal expansion element 54, 56, 55, 58. To open the pathway, the first thermal expansion element 54, 56 stretches to an extended configuration in response to the coolant having a first temperature. To close the pathway, the second thermal expansion element 55, 58 stretches to an extended configuration in response to the coolant having a second temperature that is above the first temperature.
