Fuel supply module

Abstract

A fuel supply module (M) where a coupler (48) for holding an outer terminal (49) is integrally projected from the upper surface of an installation base member (2) and where an inner terminal (52) and an electricity supply terminal (47) are electrically connected via a lead wire (50). The inner terminal (52) continues to the outer terminal (49) and projects from the lower surface of the installation base member (2). The electricity supply terminal (47) projects from the upper surface (18a) of an electric pump (Ep). A connection tube (29) is integrally formed with the installation base member (2), and a fuel discharge tube (30) of the electric pump (Ep) is fitted from below into the connection tube (29) so as to communicate with a fuel take-out tube (12). The inner terminal (52) is placed radially outside of the electric pump (Ep). A regulator valve (R) is attached to the installation base member (2), between the inner terminal (52) and the connection tube (29). The construction above enables the installation base member and the electric pump to be arranged close to each other, making the fuel supply module compact.

Description

technical field [0001] The present invention mainly relates to a fuel supply module for supplying fuel to a fuel injection valve of an engine, and particularly relates to an improvement of a fuel supply module as described below, the fuel supply module having: a mounting base member for mounting The fuel output pipe is protruded from the top wall of the fuel tank and the upper surface; the electric pump is supported on the installation base part and is accommodated in the fuel tank, and pumps the fuel in the fuel tank and delivers it to the fuel tank. an output pipe; and a pressure regulating valve, which returns a part of the fuel discharged from the electric pump to the fuel tank to adjust the discharge pressure of the electric pump; The connector of the outer terminal is connected to the outer terminal and the inner terminal protruding from the lower surface of the installation base member is connected to the power supply terminal protruding from the upper surface of the el...

AI Technical Summary

Problems solved by technology

[0004] In the conventional fuel supply module of this type, the inner terminal protruding from the lower surface of the mounting base member is arranged approximately directly above the power supply terminal protruding from the upper surface of the electric pump, so there needs to be an upper and lower connection between these two terminals. There is a working space for connecting wires in the direction, and since the pressure regulating valve extends below the installation base part and is arranged on one side of the longitudinal fuel passage connected with the fuel injection pipe of the electric pump, in order to carry out this setting , it is necessary to form a long vertical fuel passage, which hinders the close arrangement of the mounting base member and the electric pump, which becomes an obstacle to the miniaturization of the fuel supply module
