Abstract
A heater for a fuel supply system including a carburetor and a manifold for an internal combustion engine, the heater including an electrically inert core and at least one PTC disposed within a cavity in the core, the PTC heater being disposed upon an electrically conductive stratum such as copper sheet and a graphite stratum disposed next adjacent the conductive stratum, the graphite stratum acting as a compressible heat transmitting gasket between the fuel heater and the carburetor whereby to heat the fuel and prevent icing.
Claims16
A heater for fuel supply systems, said heater comprising:
- an electrically inert core having an aperture therein for the passage of a fuel-air mixture therethrough;
- and
- at least one PTC heater disposed within a cavity in said core, said PTC heater being disposed upon an electrically conductive heat transmitting metal stratum, whereby to conduct current from one side of a power supply to one side of said PTC heater;
- and
- means connecting the other side of said PTC heater to the source of the electricity and means electrically insulating said connecting means from the other elements of said heater;
- and
- a graphite stratum disposed against said electrically conductive heat transmitting metal stratum whereby to act as a heat transmitting gasket for attachment of the heater to a carburetor.
In combination with a manifold and a carburetor of an internal combustion engine, a heater for heating fuel supply systems disposed between said manifold and said carburetor, said heater comprising:
- an electrically inert core having an aperture therein for the passage of a fuel-air mixture therethrough;
- and
- at least one PTC heater disposed within a cavity in said core, said PTC heater being disposed upon an electrically conductive heating transmittal metal stratum whereby to conduct electricity to one side of a power supply to one side of said PTC heater;
- and
- means connecting the other side of said PTC heater to the source of electricity and means electrically insulating said connecting means from other elements of said heater, said manifold, and said carburetor;
- and
- a graphite gasket stratum disposed between said carburetor and said conductive heating transmittal metal stratum, whereby heat from said PTC heater is carried to said carburetor from said PTC heater.
