A thermostatic valve for a cooling circuit of a motor vehicle may include a thermostat housing part, a connector, a connector sleeve and an expansion element including a hearing resistor. The connector and the expansion element may each be insertable into the connector sleeve via a sealed and mechanically plugged-in connection. The connector and the expansion element together with the connector sleeve may define an assembly. The assembly may be insertable into the thermostat housing part via another sealed and mechanically plugged-in connection. The connector and the heating resistor may define an electrically conductive connection when the connector and the expansion element are inserted into the connector sleeve.

A thermostat for an engine cooling system is arranged between an engine and a radiator. The thermostat may include: a housing having a coolant inlet through which inflow coolant flows in from the engine and a radiator side outlet; a main valve provided in the housing and coupled to one side of a wax to open and close the radiator side outlet by a change in volume of the wax; and a heating unit coupled to the other side of the wax to supply heat to the wax.

A vehicle fan shroud de-icing assembly includes a vehicle radiator, a fan shroud installed to the radiator, a fan and a heat providing member. The fan is installed to the fan shroud adjacent to the radiator and is configured to selectively move air between heat transferring fins of the radiator. The heat providing member is attached to one of the radiator and the fan shroud. The heat providing member is positioned and configured to provide heat to the fan shroud and/or radiator in order to melt ice, show and shush retained within the fan shroud or on surfaces of the radiator.

An electronic thermostat, into which cooling water is flowed from a cylinder head of an engine through a first inlet, controls the flow rate of the received cooling water supplied to outside ambient air exposure. The electronic thermostat includes a first valve for controlling the flow rate of the cooling water supplied to a first passage for connecting a first outlet of the electronic thermostat and a water pump and includes a second valve for controlling the flow rate of the cooling water flowing through a second passage for connecting the outlet of a radiator and a cylinder block of the engine.

An electronically controlled thermostat device simplifies an insulating structure and external portions of the lead wires of a heater incorporated for temperature control of a thermo-element, reduces the number of different parts, and facilitates assembly. A pair of insulating rod pieces clamps the heater at the front and clamps a pair of lead wires from the heater while maintaining an insulated state, and a connector member attached to a side of the insulating rod pieces opposite the portion that holds the heater is mounted on the outside of a device housing. The connector member at an inner end has connector terminals provided with a pair of lead end connecting pieces to which the lead wires are connected, and has an engaging concave portion that engages an engaging convex portion for preventing twisting provided on a side of the insulating rod pieces opposite the portion that holds the heater.

An air flow controller for an air cleaner and an air cleaner are provided. The air flow controller may include a fan, and a housing, the fan being provided in the housing and the housing being movable from an initial horizontal position in which the air flow controller directs air flow in a vertical direction to an inclined position in which the air flow controller directs air flow in a diagonal direction.

A method, controller, and internal combustion engine including the controller and operable in accordance with the method by: determining a temperature of a working liquid in an engine block circuit (31, 35) of the internal combustion engine (10), the working liquid comprising a cooling liquid or a lubrication liquid; operating the internal combustion engine (10); engaging a thermal load responsive to the temperature of the liquid being below a first temperature threshold, wherein engaging the thermal load comprises at least one of increasing a pumping load of the internal combustion engine (10), or changing an air/fuel ratio, thereby adding heat to the engine block circuit (31, 35); controlling the thermal load as a function of the temperature of the liquid; and disengaging at least a portion of the thermal load responsive to the temperature of the liquid being above the low temperature limit.

A heating cartridge with a thermally conductive tube which can be immersed in a thermodilatable material of a thermostatic member. Having a cylindrical body extending axially via a flare; internal electric heating; a base of a plastic material, secured to the tube by overmolding the flare, supporting an electrical connection between the heater and an external current source, and is suitable to be received in a casing of the valve housing. A seal is attached to the base and has a first portion pressed radially against the housing in the casing so as to seal the interior of the casing. In order to improve the sealing of said cartridge, the seal also includes a second portion, which is separate from the first portion and which is pressed radially against the cylindrical body of the tube to seal the overmolding interface between the flare of the tube and the base.
