Abstract

The invention provides a fuel tank system capable of simplifying and minimizing a mounting portion of a fuel pump in a fuel tank, and a fuel tank capacity can be enlarged; the fuel tank system (10) comprises the following structures: the fuel tank (20) arranged below the bottom plate (11); a fuel pump assembly (30) arranged in the fuel tank (20); a vent valve (40) arranged on an upper portion (21) of the fuel tank (20); a storage device (50) arranged on the bottom (22) of the fuel tank (20). The fuel pump assembly (30) comprises the following elements: a pump flange (31) as the mounting portion; a carrier (32) extending from the pump flange to the fuel tank; the fuel pump (33) supported by a front end of the carrier and used for outputting fuel; a filter (34) arranged in the fuel pump (33) and absorbing the fuel stored in the storage device (50); a fuel piping (35) connected with the fuel pump (33).

Description

technical field [0001] The present invention relates to a fuel tank system including a fuel tank storing fuel, and a fuel pump unit inserted into an insertion port provided in the fuel tank to deliver fuel to the outside of the fuel tank. Background technique [0002] In order to supply the fuel stored in the fuel tank to the internal combustion engine, a fuel pump that delivers fuel is used. Patent Document 1 is known as a technique for attaching a fuel pump unit having such a fuel pump to a fuel tank, for example. [0003] In the fuel tank system disclosed in Patent Document 1, an insertion opening is provided on the upper surface of the fuel tank, and a fuel pump assembly including an accumulator storing fuel and a fuel pump is inserted into the fuel tank through the insertion opening. The fuel pump unit is provided with a fuel pump inside the reservoir, and connects a pillar extending upward from the reservoir to the flange. The outer diameter of the flange portion is ...
