Embodiment Construction

[0039] Figure 1a A cross-sectional view of a filter device according to the invention is shown for accommodating a filter element missing in the present case.

[0040] Figure 1b further shown in Figure 1a A detailed view of the filter arrangement according to the invention described in .

[0041] According to the exemplary embodiment, the filter device is designed as an oil filter for an internal combustion engine of an agricultural motor vehicle, not shown, but the filter device can also be used to filter every other drive fluid of the motor vehicle, for example for a drive fluid provided to drive an internal combustion engine. Fuel or hydraulic fluid used to operate auxiliary vehicle assemblies in motor vehicles. Alternatively, an application as an air filter or the like is also conceivable.

[0042] Agricultural vehicles are, for example, tractors, harvesters, lawn mowers or the like.

[0043] The filter device is preferably located in the engine compartment of the mo...

Abstract

The present invention relates to a filter arrangement for filtering a liquid or gaseous medium, having a filter housing (10) for accommodating an exchangeable filter insert (44), wherein the filter housing (10) has a housing head (12) and a housing cover (16) that can be removably connected to the housing head (12) by means of a connecting element (14). According to the invention the connecting element (14) interacts with a locking element (26) associated with the housing head (12) such that for the purpose of assembly the housing cover (16) can be connected to the housing head (12) only if a filter insert (44) is located in the filter housing (10).

Description

technical field [0001] The invention relates to a filter device for filtering liquid or gaseous media, which has a filter housing for accommodating a replaceable filter element, wherein the filter housing has a housing top and is connected to the housing by means of connecting elements A releasably attachable housing cover on top of the body. The invention further relates to a filter element for use in a filter device of the aforementioned type, a method for releasing a connecting element of a filter device of this type, and its use in motor vehicles, in particular agricultural vehicles. Background technique [0002] Filters for purifying liquid or gaseous media in motor vehicles are used in various embodiments, for example as oil filters for driving internal combustion engines. In order to ensure constant lubrication of the internal combustion engine, burnt parts of the oil, metal grinding and other contamination are filtered out by means of suitable oil filters. The oil ...
