APARATO DE BOMBEO DE COMBUSTIBLE PARA SUMINISTRAR COMBUSTIBLE A UN MOTOR DE COMBUSTION INTERNA

摘要

A fuel pumping apparatus for supplying fuel to an internal combustion engine includes a pump having a body and a solenoid operated fuel control device. The current flow to the solenoid is controlled by a control circuit mounted on circuit boards located within an inner casing secured to the body. An outer casing surrounds the inner casing and defines a space which is connected with a fuel inlet, the space communicating with a fuel inlet of the pump. The flow of fuel through the space assists the cooling of the components of the control circuit.
