There is provided a thermostatic working element comprising: a housing for receiving an expansion medium; an electric heating element arranged in the housing and provided with connecting lines, wherein a base of a bottom side of the housing comprises an opening for passage therethrough of the connecting lines; and a gasket disposed between the electric heating element and the base of the bottom side of the housing, essentially surrounding the opening, wherein the housing further comprises a recess located in proximity to the electric heating element, configured to press the electric heating element and the gasket against the base of the bottom side of the housing and thereby sealing of the housing is facilitated.

Electrically heated thermostatic working element

An apparatus for controlling a temperature for an engine by controlling a flow of a liquid engine coolant through a coolant conduit, the apparatus including a thermostat having a temperature responsive valve for substantially blocking and substantially unblocking the flow of the liquid coolant to a radiator. The valve opens as the temperature of the liquid coolant rises and a spring urges the valve to a closed position as the temperature of the fluid falls. An electromechanical actuator is provided outside of the conduit and is controlled by an engine control system in response to engine conditions. It is connected to the valve by a connector assembly extending between the electromechanical actuator and the valve through the coolant conduit, the connector assembly being positioned relative to the valve to cause the spring to be compressed as the electromechanical actuator opens the valve so that the valve is opened and closed in response to a coolant temperature by said thermostat and positioned within a range of travel by said electromechanical actuator.

Electromechanical failsafe thermostat

An apparatus for controlling a temperature of an engine by controlling the flow of a liquid engine coolant to a radiator is disclosed. The apparatus includes a thermostat having a thermally responsive valve for substantially blocking or opening the flow of coolant to the radiator to maintain the engine at or about a preferred engine operating temperature. Also included is a thermally activated actuator for opening the valve in response to an engine condition such as load or a need for power. The actuator is activated at a temperature different than the thermostat. A source of electro thermal energy is provided to motivate the actuator so the valve may be opened on demand. In one aspect the invention provides a method of controlling the temperature of the engine by opening the valve in response to engine monitoring.
