Abstract
The disclosure illustrates an electronically controlled fuel pump in which the microprocessor is cooled by the fuel extending to the inlet of a positive displacement pump. The cooling passage has a labyrinth flow path and the heat sinks of the microprocessor transfer heat to the passage through conduction. An auxiliary pump causes fuel to flow through the heat exchange passage during certain conditions, such as shutdown, to maintain the temperature of the microprocessor below a predetermined maximum. Transducers and other control elements associated with the microprocessor are maintained in a cavity in the fuel pump to protect them from the environment and a pivotal connection with appropriate placement of the leads is provided in the housing for ready access to these transducers and control elements.
