Embodiment Construction

[0020] figure 1 Shown is a feed unit for feeding fuel from the fuel tank of the motor vehicle to the internal combustion engine of the motor vehicle (not shown). The device has an electrically driven fuel pump 2 and a fine filter 3 arranged in a swirl pot 1 . The fine filter 3 is also arranged in the swirl tank 1 and connected to the fuel pump 2 through the fuel pipe 4 . Furthermore, the fine filter 3 has a connecting pipe connection 5 for a drain line of the internal combustion engine, not shown, which leads to the fuel tank. exist figure 2 The pipe 7 for the suction injection pump 8 shown in is connected to the connection 6 of the fuel pump 2 . The suction jet pump 8 sucks fuel from around the swirl pot 1 and delivers the fuel to the swirl pot 1 . The swirl pot 1 is used to collect fuel and has a bottom plate 9 and a housing 10 sealingly connected to the bottom plate 9 . A suction connection 11 of the fuel pump 2 protrudes through a prefilter 12 into a collecting chamb...

Abstract

A delivery unit for delivering fuel in a fuel tank comprises a prefilter (12) and a swirl pot (1) which are produced as one piece. The prefilter (12) is produced during die-casting of the swirl pot (1). The invention allows the delivery unit to be produced in an especially inexpensive manner.

Description

technical field [0001] The invention relates to a delivery unit for conveying fuel from a fuel tank of a motor vehicle, the unit having a swirl pot for collecting the fuel and a prefilter for filtering the fuel drawn out of the swirl pot. Background technique [0002] Such delivery units are frequently used in today's fuel tanks and are known from practice. The pre-filter is often designed as a separate component and is fitted to the swirl pot or to the fuel pump which draws fuel from the swirl pot. This leads to complicated manufacture and installation of the prefilter. In addition, the prefilter may abut against the fuel pump or swirl pot components thereby limiting the available filter area. And slim filters increase the risk of inhaling air. Contents of the invention [0003] The object of the invention is to develop a delivery unit of the type mentioned at the outset in such a way that it can be produced particularly cheaply. [0004] According to the invention, t...
