A thermally and electrically conductive housing having a solid tip portion is shown mounting a heating element thermally and electrically coupled to the tip portion which in turn is electrically coupled to a switch mechanism mounted within the housing. The switch mechanism includes a thermostatic snap acting disc adapted to bias a movable electrical contact away from a stationary electrical contact at preselected temperatures. The housing is shown mounted in a carburetor of an automobile to contact energization of a honeycomb heater disposed in the carburetor, however; the device can be used in other locations where it is desired to maintain a body within a selected temperature range.

Heating device

A fuel supply device and heating device or system for an electrically controlled fuel injection engine has an air intake and a fuel injector arranged to direct air and fuel respectively into a cylinder inlet passageway leading to a cylinder inlet valve opening in an engine cylinder and has a heating device located in the passageway having a heating surface arranged to receive fuel from the fuel injector for heating the fuel and deflecting it or directing it into the cylinder through the cylinder inlet valve opening substantially free of condensing contact with walls of the passageway, thereby to assure that the proper ratio of air and fuel as provided by the electronic controls of the engine are properly received in the engine cylinder.

Fuel supply device and heating device

A fuel heating device comprises an electroconductive inner tube which forms a passageway for fuel to be heated. A heater having a positive coefficient of resistance (PTC) is fixed to the side of the outside surface of this electroconductive inner tube, a resilient electrode contacts this heater from the side of its outside surface, and a first electrically and thermally insulating outer tube is provided around the entire periphery of the aforementioned electroconductive inner tube to cover the aforesaid heater completely for holding the electrode compressed to the heater. A second electrically and thermally insulating outer tube is provided around the entire periphery of the first tube, said second tube including means for mounting the device for use.
