Embodiment Construction

[0013] The filter device shown in FIG. 1 has a housing generally indicated at 10 . The housing 10 consists of at least two housing parts 12, 14 which are detachably connected to each other, wherein the first housing part 12 is designed according to a filter tank, while the second housing part 14 forms A kind of cover. Viewed from the viewing direction of FIG. 1 , the housing part 12 is surrounded at its upper end by an annular plug-in flange 16 which is closed at its upper end for insertion into a fluid tank not shown in the drawing. There is an annular support washer 18 . As other housing parts of the housing 10, viewed from the viewing direction of FIG. 1, an inflow connection 20 is connected to the left and a closable connection point 22 is connected to the right, for example for connecting a not shown in detail in the figure. The dirt indicator, which works, for example, on the basis of a differential pressure. The housing 10 communicates at its bottom with an outflow c...

Abstract

The invention relates to a filter device with a housing (10) composed of at least two housing parts (12, 14) which are to be connected detachably to one another, said housing holding a filter element (26) which comprises a support tube (28) and a filter material (32) surrounding the support tube (28), wherein the ends (34, 36; 38, 40) of the support tube (28) and filter material (32) run into at least one holding part (42, 46; 44, 48). Since, according to the characterizing part of claim 1, the filter material (32) can be withdrawn in a direction (50) to separate it from the support tube (28) and since, in this direction (50) of withdrawal, the support tube (28) and the filter material (32) alike are provided with a predeterminable taper, it is possible for the contaminated filter material (32) to be readily withdrawn from the support tube (28) such that the support tube (28), together with its holding parts, can be reused in conjunction with a newly inserted filter material (32).

Description

technical field [0001] The invention relates to a filter device having a housing consisting of at least two housing parts detachably connected to one another, the housing housing a filter element having a support tube and a filter material surrounding the support tube , wherein the ends of the support tube and the filter material pass into at least one receiving portion. Background technique [0002] Relevant filtering devices of various structural forms can be bought freely on the market. The construction of filter elements consisting of filter material and support tubes varies from manufacturer to manufacturer. In the case of a single paper element, the filter material is produced without a supporting wire mesh, so that under higher differential pressure conditions compression of the filter material wrinkles occurs on the filter element. This reduces the drainage capacity on such corrugated filter materials, so that many of the corrugated areas cannot be used for filtrat...
