Embodiment Construction

[0016] The device 1 according to the invention comprises a controller housing 2 in which a carrier 3 with control electronics 4 for controlling a fuel delivery pump 5 is arranged and which comprises a pressure Sensor 6 for measuring the pressure outside the controller housing 2 . The carrier 3 of the control electronics 4 can be, for example, a circuit board on which the electronic components 7 and the conductor tracks 8 of the control electronics 4 are arranged.

[0017] It is provided according to the invention that the pressure sensor 6 is arranged in the controller housing 2 and is electrically connected to the control electronics 4 and is provided with a pressure connection opening 12 leading into the controller housing 2 for measuring pressure in the controller housing 2. external pressure. In this way, the pressure sensor 6 is electrically attached to the control electronics 4 in a simple manner, in particular without complicated wiring to the outside of the controller...

Abstract

Devices for a fuel delivery module, comprising a control housing, in which a carrier having control electronics for controlling a fuel delivery pump is arranged, and comprising a pressure sensor for measuring a pressure in the fuel tank, i.e. outside of the control housing, are already known. The problem is the fact that the pressure sensor requires separate cabling, which, for example, comprisesa voltage supply for the pressure sensor and a signal line and must be laid during production in a relatively elaborate manner. This problem is solved by the device according to the invention in thatthe separate cabling for the pressure sensor is omitted or at least shortened such that the production costs can be reduced. According to the invention, the pressure sensor (6) is arranged in the control housing (2) and is electrically connected to the control electronics (4).

Description

technical field [0001] The invention proceeds from an arrangement for a fuel delivery module of the type according to the independent claim. Background technique [0002] A device for a fuel delivery module is known from EP 1 031 725 A2, which has a controller housing in which a carrier with control electronics for controlling a fuel delivery pump is arranged, and which The device has a pressure sensor for measuring the pressure in the fuel tank, ie the pressure sensor is outside the controller housing. A disadvantage is that the pressure sensor requires a separate wiring, which includes, for example, the voltage supply and the signal lines for the pressure sensor and which is relatively complex to arrange during production. Contents of the invention [0003] In contrast, the device according to the invention having the features of the characterizing part of the independent claim has the advantage that separate wiring for the pressure sensor is eliminated or at least shor...
