Problems solved by technology

As a result, the height of the filter member is limited, so the filtering area of ​​the filter member has to be reduced
In addition, when the filter area is increased by increasing the size of the filter member, it will inevitably lead to an increase in the size of the fuel supply device.

Abstract

The invention provides a fuel supply device which can expand filtering area of a filter component and realizing miniaturization of device. The fuel supply device comprises an installation plate, which is used for sealing an opening part of a fuel tank; a fuel pump, which is vertically arranged on the installation plate; an absorption filter, which is used as a bag shaped filter component and is arranged and paralleled to the fuel pump for filtering the fuel in the fuel pump; a straight tube shaped horizontal fuel passageway for making the fuel ejected from the jet of the fuel pump flow along the horizontal way. The shape of the filter component of the absorption filter is in flat shape, and in the top view, the filter component is arranged and paralleled to the horizontal fule pasageway.

Description

technical field [0001] The present invention relates to a fuel supply device for supplying fuel in a fuel tank to an internal combustion engine, ie, an engine. Background technique [0002] In a conventional fuel supply device, there is a fuel supply device including: a cover member for closing an opening formed at the bottom of the fuel tank; a fuel pump arranged vertically on the cover member; a suction filter It is arranged side by side with the fuel pump, and has a bag-shaped filter member for filtering the fuel to be sucked into the fuel pump; a straight pipe-shaped horizontal fuel passage, which is used for injection from the injection port of the fuel pump The output fuel flows in the lateral direction; the vertical fuel passage for the fuel in the horizontal fuel passage to flow downward; and the pressure adjustment valve for adjusting the pressure of the fuel in the horizontal fuel passage (for example, refer to Patent Document 1). [0003] Patent Document 1: Japan...
