Description

This utility model relates to the design of a device for a fuel supply system of an internal combustion engine (ICE) having a gasoline pump installed in a vehicle’s fuel tank, a lid covering an opening in a fuel tank through which a pipe connecting an electric gasoline pump to an internal combustion engine power line, and also a pipe pressure relief from the internal combustion engine supply line to the fuel tank when the fuel pressure in it exceeds a permissible value.

DE application No. 19615081 describes a device comprising a container mounted in a fuel tank of a vehicle, which is connected through an elastic element made in the form of a bellows to a casing of a gasoline pump, which in turn is connected to a cylindrical tide of a lid covering the opening in the fuel tank. The device contains two nozzles passing through the cover. A pipeline from an electric gas pump is connected to the inner end of one pipe, the other end of this pipe is designed to connect to the ICE supply line. The second pipe is designed to connect to the fuel drain line from the supply line if it is exceeded

pressure is higher than permissible. The tank contains openings connecting it to the tank of the fuel tank and ensuring the flow of fuel into the tank. The device contains a plug mounted on the lid, and wires connecting it to the terminals of the gasoline pump.

The disadvantages of this module include the significant complexity of manufacturing its constituent elements, as well as the high metal consumption and, as a consequence, the high cost of the module.

Also known is the "Electric Gas Pump Module" according to the utility model of the Russian Federation No. 25789. The module includes an electric motor, fuel pipes, a metal cover, an electrical connector and electrical wires connecting the motor power terminals to the contacts of the electrical connector, the electrical wires in the area between the electric motor and the metal cover are enclosed in a metal braid. The end of the metal braid located near the cover is electrically connected to the cover and to the fuel-conducting metal tube. The end of the metal braid, located near the electric motor, is electrically connected to the metal tube, and the electrical connection of the ends of the braid is carried out through plates welded to the fuel pipes. In the middle part of the fuel pipes, a plate is welded on which a fuel level sensor is fixed.

This module also has a rather complicated design. The use of fuel pipes of stainless steel of a sufficiently large length leads to an increase in the cost of the device design.

The basis of this utility model was the task to develop a device for the internal combustion engine power supply system, which would have a simple design and would have an inexpensive price.

This goal is achieved by the fact that the inventive device contains a bracket rigidly connected to the cover, on which are mounted an electric gas pump, a fuel level sensor, electric wires and fuel pipes, and the fuel pipes are made of plastic, for example, polyamide.

A distinctive feature of the claimed module is the presence of a bracket made in the form of an elongated, curved plate, one edge of which is bent along the length, longitudinal grooves are extruded along the plane, and in the middle part there are holes for fixing the fuel level sensor. One end of the bracket is rigidly connected to the cover, the gasoline pump is fixed at the other end, and the fuel level sensor is fixed in the middle, electrical wires and pipelines are fixed to the bracket, and the bracket is made of metal.

Another distinctive feature of the proposed module is that it contains two insignificant lengths of the pipe passing

through a cover rigidly and hermetically connected to it. These pipes are intermediate in the creation of the internal combustion engine power supply circuit and the fuel drain circuit from it. The cover and the nozzles passing through it are made of metal.

Another distinctive feature of the module is that the cap, the nozzles passing through it and the bracket can be made as a whole and made of plastic.

The inventive module of the gasoline pump includes an electric gasoline pump, outlet and inlet pipelines, a lid covering the hole in the fuel tank, on which are fixed an electrical connector and two nozzles passing through the lid, a pipe is connected to the inner end of one nozzle from the electric gasoline pump, the other end is for connecting with a supply line, a fuel drain pipe is connected to the inner end of the other pipe, and the other end is connected to a drain pipe, fuel level sensor, and electric wires connecting the power terminals of the gas pump electric motor to the contacts of the electric connector, a bracket, one end of which is rigidly connected to the cover, an electric gas pump is fixed at the other end, and a fuel level sensor is fixed in the middle part, and electric wires and pipelines are fixed to the bracket.

In more detail, the claimed device is discussed in the drawings. Figure 1 shows the design of the inventive module. Figure 2 presents the design of the cover. Figure 3 presents the appearance of the bracket in plan. Figure 4 shows a side view of the bracket.

In the drawing of FIG. 1, it is indicated: 1 — a bracket, 2 — a cover covering the hole in the fuel tank (not shown in the drawing), 3 — an electric gas pump, 4 — a coarse filter, 5 — a plug connector, 6 — a fuel supply pipe, 7 — fuel drain pipe, 8-electric wires, 9 - fuel supply pipe, 10 - fuel drain pipe, 11 - fuel level sensor, 12 - cable tie securing electric wires and fuel supply and drain pipes.

In the inventive device, the main connecting link of all the elements is the bracket 1. One end of the bracket is rigidly connected to the cover 2, the gasoline pump 3 with the coarse filter is fixed at its other end 4. The plug 5 is fixed to the outside of the cover 2. The cover is also fixed rigidly and the fuel supply pipe 9 and the fuel drain are hermetically sealed 10. The pipe 6 is connected to the inner end of the fuel supply pipe 9 by one end 6, its second end is connected to the electric gas pump 3. To the internal

the end of the pipe 10 is connected to the fuel drain 7, the second end of the pipeline is fixed to the body of the gasoline pump near the coarse filter. When fuel is drained from the injection line of the fuel supply to the internal combustion engine, which occurs when the pressure relief regulator (not shown in the drawings) is triggered, the jet of already cleaned fuel flows around the coarse filter and practically does not need to be cleaned. The fuel level sensor 11 is fixed in the middle part of the bracket 1. The electric wires 8 and the fuel supply pipes 6 and the fuel drain 7 are fixed to the bracket 1 with ties 12.

The supply pipes 9 and the fuel drain 10 pass through the cover 2 and are rigidly and hermetically connected to it, for example, by welding. At the ends of the nozzles 9 and 10 that extend into the inside of the cap, fittings 13 are fixed for connecting the supply pipelines 6 and draining the fuel 7.

Figures 3 and 4 show the design of the module bracket. The bracket is made in the form of an elongated, curved plate containing four rectilinear sections 14, 15, 16, 17, each of which is located at an angle to the adjacent section, forming a sickle-shaped figure. The end of section 14 contains a sample 18, reducing the width of the plate, and the hole 19, designed to secure the gasoline pump 3. On section 15 of the bracket holes are made 20, 21, 22, designed to fix the fuel level sensor 11. The end of section 17 is bent into

technological purposes to ensure optimal connection of the bracket 1 and cover 2 during welding. In section 16, the bracket is bent so that section 17 lies in a plane parallel to the plane of sections 14 and 15. In sections 14, 15 and 17, longitudinal grooves 23 are extruded in the direction of the plate axis. On the outer edge in sections 14, 16, 17 and partially in section 15, a bend is made 24. The extruded longitudinal grooves 23 and the bend 24 of the edge of the plate are designed to increase its rigidity.

The described form of the bracket cannot cover the possibility of manufacturing a bracket of another shape, without going beyond the scope of this utility model. For example, the bracket can be made in the form of an elongated plate, where sections 14, 15, 16 are combined into one arc-shaped section. The bracket can be made not only of metal, but also of plastic. Moreover, the bracket 1, the cover 2 and the fuel supply pipes 9 and the fuel drain 10 passing through it can also be made as a whole and made of plastic.
