Fuel supply flow regulating device for vehicles thermal engine, has control unit controlling electric motor according to maximum rotation speed during starting phase and minimum rotation speed when starting phase is terminated

摘要

The device has a fuel tank (1) with a storage tank (4), and a fuel pump (8) driven by a DC electric motor (9). A pipe (13) returns the excess fuel pumped by the fuel pump towards the tank. A control unit (14) controls the motor according to a maximum rotation speed during a starting phase of a thermal engine and according to a minimum rotation speed when the starting phase of the engine is terminated. An independent claim is also included for a method of regulating a fuel supply flow of a thermal engine of a motor vehicle.
