Embodiment Construction

[0040] Attached figure 1 In longitudinal section, a liquid filter 1 , in particular an oil or fuel filter of an internal combustion engine, is shown in its fully assembled state. The liquid filter 1 is designed as an upright filter with a cup-shaped filter housing 10 and an upper screw cap 11 . A filter insert 3 is arranged on the standpipe 2 in the interior of the filter housing 10 . The standpipe 2 is inserted with its lower end 51 sealingly into the socket 17 which is part of the filter housing 10 .

[0041] The filter housing 10 has a raw liquid inlet 13 which here is embodied in the form of a pipe connection and which opens into the filter housing 10 radially from the outside here. Parallel to the raw liquid inlet 13 , offset downwards relative thereto, runs the cleaned liquid outlet 14 , which is likewise designed as a pipe connection and leads radially away from the filter housing 10 . exist figure 1 At the bottom of the filter housing 10 there is arranged a liquid ...

Abstract

A liquid filter with a replaceable filter insert and a housing having a raw liquid inlet, a central clean liquid outlet, and an eccentric liquid discharge channel. A standpipe extends above the liquid outlet and receives the insert. The insert has an eccentric closing pin. A first positioning arrangement is arranged on the clean liquid outlet and a lower end region of the standpipe so that, when the standpipe is plugged into the clean liquid outlet, the standpipe is guided into a particular position relative to the filter housing. A second positioning arrangement is arranged on the standpipe and the insert so that, when the insert is plugged onto the standpipe, it is guided into a particular position relative to the standpipe. The positioning arrangements are matched to one another so that the closing pin on the insert enters into engagement with the discharge channel in the filter housing.

Description

technical field [0001] The invention relates to a liquid filter, in particular an oil or fuel filter for an internal combustion engine, with a filter housing and a filter insert arranged exchangeably therein, wherein the filter housing has a raw liquid inlet ( Rohfluessigkeitszulauf), central cleansing liquid outlet (Reinfluessigkeitsablauf) and eccentric liquid discharge channel, wherein a central standpipe (Standrohr) is arranged above the cleansing liquid outlet, wherein the filter element is slipped onto the standpipe, wherein the filter element rests on it has an eccentric closing pin on the side facing the liquid outlet channel, and wherein positioning means are provided which guide the closing pin into engagement with the eccentric liquid outlet channel when the filter element is slipped onto the standpipe. Background technique [0002] A liquid filter of the aforementioned type is known from DE 10 2009 049 868 A1. In this liquid filter, the standpipe is designed as ...
