liquid filter

Abstract

The invention relates to a liquid filter (100), in particular a fuel filter, comprising a filter housing (200) with a cover (210), wherein the cover (210) has at least one cover opening (220); And the liquid filter also includes a filter element (300) arranged in the filter housing (200) and provided with an end cover (310), wherein the end cover (310) has a pipe joint configured as a tube pieces (320). In order to be able to replace the filter element ( 300 ) in the liquid filter as easily as possible and without confusion, it is provided here that the nipple ( 320 ) fits through the lid opening ( 220 ) and has a connection end A portion (326) protrudes from the filter housing (200). Furthermore, the invention relates to the use of a liquid filter (100) in a fuel supply system of a motor vehicle, the fuel supply system further comprising a fuel reservoir arranged upstream of the liquid filter (100) and a Injection device for fuel downstream of the liquid filter (100). Furthermore, the invention also relates to a filter element (300) used in a liquid filter (100).

Description

technical field [0001] The invention relates to a liquid filter, in particular a fuel filter, and to the use of a liquid filter in a fuel supply system of a motor vehicle and to a filter insert for a liquid filter, having the features of the independent device claim. Background technique [0002] Liquid filters are used in many industrial products. They are preferably used in line systems for separating particles or undesired liquid fractions which would also form an emulsion with the liquid to be filtered from the liquid to be filtered. A "liquid fraction" in the sense of the present application means an individual liquid in a liquid mixture, for example water in a fuel-water mixture. The filtering is often necessary to prevent components or devices of the piping system downstream of the liquid filter from being affected by particulates and / or undesired liquid fractions because these components or devices Otherwise it may be damaged or its function may be adversely affect...

AI Technical Summary

Problems solved by technology

[0005] However, with the liquid filter and the filter element for the liquid filter provided in the prior art, it cannot be easily found whether the filter element has been installed in the liquid filter during maintenance.

It can thus occur that the liquid to be filtered flows through the liquid filter unfiltered and particles present in the liquid damage components or devices of the piping system downstream of the liquid filter or adversely affect its function
