Embodiment Construction

[0015] figure 1 A delivery unit 1 for use in a fuel tank 2 of a motor vehicle is shown. The delivery unit 1 consists of a flange 3 and a swirl pot 4 . Flange 3 is designed such that it closes opening 5 of fuel tank 2 through which delivery unit 1 is inserted into fuel tank 2 . A fuel pump (not shown) is located in the swirl pot 4 , which feeds fuel from the swirl pot 4 via the flange 3 to a not shown internal combustion engine of the motor vehicle. Guides 13 are provided on the circumference of the swirl pot 4 , in which guides a respective support element 6 engages. Each support element 6 is surrounded by a helical spring 7 . The helical spring 7 is supported on the flange 3 and on the guide 5 and in this way pretensions the swirl pot 4 against the bottom 8 of the fuel tank 2 .

[0016] figure 2 and 3 A flange 3 with a support element 6 is shown. In order to fix the bearing element 6 , the flange has a sleeve 9 into which the bearing element 6 is pressed. In the uppe...

Abstract

The invention relates to a delivery unit for delivering fuel from a fuel reservoir to an internal combustion engine of a motor vehicle. Said delivery unit comprises a fuel pump which is arranged in a swirl pot, and a flange which closes an opening of the fuel reservoir, the swirl pot being connected to the flange via at least two supporting elements. The supporting elements consist of a fuel-resistant plastic material.

Description

technical field [0001] The subject of the invention is a delivery unit for delivering fuel from a fuel tank to an internal combustion engine of a motor vehicle, which has a fuel pump arranged in a swirl pot and a flange which closes the opening of the fuel tank, Wherein the anti-swirl tank is connected to the flange through at least two supporting elements. Background technique [0002] Delivery units of this type have been known for a long time and are therefore prior art. It is also known to design the support element as a metal tube. The support element is pressed into a receiving sleeve in the flange by means of a press fit. On its circumference, the swirl pot has corresponding guides, in which the support elements are longitudinally displaceably guided. The helical springs surrounding the support elements are supported with one end on the respective support element or on the flange and with the other end on the swirl pot and have the effect of pretensioning the swirl...
