Abstract: A heated fuel injector for supplying fuel to a fuel consuming device includes a fuel inlet for receiving fuel, a fuel outlet for dispensing fuel from the fuel injector, and a fuel injector body extending along an axis and fluidly connecting the fuel inlet to the fuel outlet such that fuel flows within the injector body. A cylindrical heating element radially surrounds the fuel injector body and operates to heat fuel flowing through the fuel injector body. An annular space is defined between the heating element and the fuel injector body sufficiently large to accommodate thermally caused radial differential expansion between the fuel injector body and the heating element. A conductive material fills the annular space and has a melting point sufficiently low to be a liquid as the heating element operates to thereby substantially prevent transfer of mechanical stress to the heating element due to the radial differential expansion.

Abstract: A combined refrigerant heating and cooling system comprises a compressor, an outside heat exchanger, an inside heat exchanger, a refrigerant-to-engine coolant heat exchanger, at least one refrigerant expansion device and at least one redirection device, wherein the arrangement is such that said compressor is switchable between a heat pump loop and a cooling loop by means of said redirection device, said heat pump loop comprising said inside heat exchanger, said refrigerant expansion device and said refrigerant-to-engine coolant heat exchanger, and said cooling loop comprising said outside heat exchanger and said inside heat exchanger. According to the invention, the outside heat exchanger is arranged in such a way that an outlet of said outside heat exchanger is connected to a connection point of said heat pump loop which in heat pump mode lies downstream of said refrigerant expansion device, e.g. between said refrigerant expansion device and said refrigerant-to-engine coolant heat exchanger.
Abstract: A cam follower having a clamp disposed on at least one end thereof. The follower includes two opposing sidewalls interconnected by a lower pallet. A roller is rotatably mounted to and disposed between the sidewalls via needled or journal bearings or other rotatable connection known in the art. A clamp is disposed about an end of the follower to induce compression force in the pallet and possibly act as the valve guide walls. The clamp increases the stiffness of the follower and induces compressive stress in the pallet area thereby increasing fatigue life. The clamp could also increase the length of the valve guide walls for better stability during engine assembly.
