Problems solved by technology

[0004] A disadvantage here is, inter alia, that the handling of the ring filter element into and out of the filter housing is difficult
Furthermore, a corresponding application of force to the filter device (in particular to the ring filter element) can lead to damage to the guide contour and / or guide element, sometimes resulting in a relative movement of the ring filter element with respect to the filter housing, thus affecting the filter Failure-free mode of device operation

Embodiment Construction

[0035] figure 1 A longitudinal section of a filter device 1 is shown, which can be configured, for example, as an oil filter 1'. The filter device 1 has a filter housing 2 and a ring filter element 3, which can be installed in the filter housing 2, wherein in figure 1 The state in which the ring filter element 3 is installed in the filter housing 2 is illustrated in . Furthermore, the filter housing 2 has a housing cover (not shown here), which is figure 1 The filter housing 2 is closed at the top in the view of , and can be detached from the remaining filter housing 2, for example by means of a corresponding thread, to be able to install the ring filter element 3 into the filter housing 2 and from the filter Shell 2 is disassembled. On its side facing away from the housing cover, the ring filter element 3 has a lower end disk 4 on which a pin 5 is arranged, arranged eccentrically to the lower end disk 4 and protruding axially from the lower end disk 4 . In the assembled s...

Abstract

The present invention relates to a filter appliance (1) having a filter housing (2) and a ring filter element (3) that is mountable into the filter housing (2), wherein the ring filter element (3) has, on a lower end disc (4) an axially protruding pin (5) which in the assembled state engages into a channel (6) of the filter housing (2). It is essential to the invention in this case that for mounting the ring filter element (3) into the filter housing (2), a guide contour (15) and two guide elements (17, 18) are provided, wherein the guide contour has at least two axial grooves (19, 20). In this case the respective guide element (17, 18) is constructed so as to be complementary to such an associated axial groove (19, 20), in such a manner, that the guide contour (15) interacts with the axial grooves (19, 20) and the guide elements (17, 18) according to the lock and key principle.

Description

technical field [0001] The invention relates to a filter device having a filter housing according to the preamble of claim 1 and a ring filter element which can be mounted in the filter housing. Background technique [0002] The filter device serves to clean or filter fluids, such as eg air or oil. For this purpose, the filter device usually has a filter element, which can be designed in particular as a ring filter element and can be installed in an associated filter housing. The loop filter element can thus be replaced if desired. Such a ring filter element has an axially protruding pin at the lower end plate which engages into an associated channel of the filter housing when the ring filter element is assembled in the filter housing. The channel can be configured, for example, as a drain channel, so that when the ring filter element is removed from the filter housing, fluid (ie in particular oil) located in the filter housing can flow out of the channel. Such filter dev...
