Abstract
PURPOSE: To save waste of operation in a fuel pump for a fuel feeding device in which an electrically driven fuel pump is used, by controlling the operation of the fuel pump with a signal from a detector for a flow rate of return fuel.
CONSTITUTION: A fuel pump 2 is driven to feed fuel to an engine 3 from a fuel tank 1 through a fuel feed pipe 5, and a surplus amount of fuel is returned to the fuel tank 1 through a return fuel passage 6. The constitution is such that output of a return fuel flow detector 4 provided in the return fuel passage 6 varies base voltage of a transistor Tr provided in an operating circuit for the fuel pump 2 to decrease a delivery amount of the pump 2 as the return fuel flow increaes. In this way, a simple and accurate control operation of the fuel pump can be performed.
