Electrically heatable thermostatic valve for a coolant circulating system of an internal-combustion engine

摘要

An electrically heatable thermostatic valve for a coolant circulating system of an internal-combustion engine in which the housing of a thermostatic working element is arranged in a stationary manner and is provided with feed lines for a heating element. The valve elements of a main valve and of a bypass valve are arranged on the working piston of the working element, the valve element of the main valve being designed such that the housing of the thermostatic working element is situated in the cold coolant flow when the main valve is closed.
