Abstract

For a thermostatic valve in the coolant circulation system of an internal-combustion engine having an expansion material element penetrating the main valve for the cold-side stationary support and the hot-side driving connection with the valve disk of the main valve, it is provided for increasing the response characteristic of the thermostatic valve to act upon the expansion material element in the cold-side end section in addition by a hot coolant and/or to provide a metal film resistor as an electric heating device placed in the expansion material.
