Thermostatic valve for cooling circuit of internal combustion engine, has Peltier-element staying in heat conducting connection with wall of operating element and extended over circumference of wall

摘要

The valve (2) has an expansion unit received in an operating element (22), so that change in temperature is converted into a power stroke of valve elements (10, 12). The operating element includes a cylindrical wall (26) that protrudes in a coolant channel, and a Peltier-element (50) is assigned to the operating element. The Peltier-element stays in heat conducting connection with the wall of the operating element, and is extended over circumference of the wall. The Peltier-element is cylindrically formed with outer and inner rings.
