Münster / Westf. Filters for liquid or gaseous media Utility model

In recent times it has become more and more common in the circles of motor vehicle owners to use it in the fuel supply line fuel filters inserted or screwed in or otherwise fastened directly to the engine block, as soon as they no longer work satisfactorily after a certain period of use, simply throw them away · Into the Relevant circles are therefore known for the abbreviation "disposable filter" »This is the reason why these disposable filters are used more and more introduced because it was possible, with the appropriate development of technology, to manufacture the filters cheaply, i.e. so too design so that the repair of unusable filters usually requires the same cost expenditure as a new acquisition »

In such a state of affairs it exists in order to come about in this way coming risk of inappropriate price increases if possible To compensate, of course, the disadvantage that there can be constructions in one sense or the other, duroh which the Usability of such filters from a technical point of view is more or less disadvantaged. Solohe disadvantages make sioh in the Usually noticeable in a shorter service life of such filters.

In order to keep the technical effect within the usual limits, the aim is with the present utility model then, as an alternative to achieve a cheap price structure, the spatial design of the filter unit, among other things. in particular the barely shaping of the actual filter insert

surrounding housing, but also the filter insert so too design that with very small, but advantageous technical means, as necessary for the assembly of such a filter are, a very advantageous mass production is guaranteed.

For this purpose, the housing that encloses the actual filter insert and is expediently chosen to be cylindrical is made of two with their edges abutting and interconnected cup-shaped container halves with attached to the front nozzle-shaped approaches, which the respective application accordingly either with a screw thread or for the purpose of slipping over a flexible hose have a bulge. These two container halves are made of any kind of plastic, advantageously even made of a transparent plastic.

With such a design of the housing which has to accommodate the filter element, the filter element itself consists of one perforated tube with attached closed bottom, with star-shaped filter surfaces glued to this bottom or cemented or fastened in any other way. Depending on the nature of the filter material but also the possibility of pouring the upper or lower edge of the filter surface either into the upper half of the pot or to bring it into firm connection with the filter edge in some other way.

In the drawing is in

Fig. 1 in partial longitudinal section such a filter body

shown,
Figure 2 shows a floor plan

As can be seen from Figure 1, the housing consists of the two pot-shaped parts 1 and 2, which with their edges 1 · and 2 'collide and are advantageously welded at this point

or otherwise firmly connected. Both with the cup-shaped Part 1 as well as the pot forming part 2 are nozzle-shaped lugs 3 and 4 provided} the one shown in Example Western margins 3 »or 4 * own to there a flexible To be able to push on the hose. For special purposes, however, the nozzles 3> 4 or one of the nozzles can be provided with a screw thread and in the latter case are suitable for to be screwed into the engine block.

In the interior of the pot halves 1, 2, the tube 5, which extends in the longitudinal direction of the housing and is provided with a corresponding perforation 6, is provided. The lower end of this tube sits on the disc surface 7 which is completely closed per se and which advantageously has a hand θ standing upwards. Upright in the present case designed star-shaped filter surfaces are $ placed for any filter material and can be useful but connected to the top surface of the upper pot 1 or even with the disc 7 by cementing, gluing, pouring or the like.

After the parts have been assembled in this way, the medium entering, for example, at the nozzle 4 occurs, regardless of whether it is is a liquid or gaseous medium and then takes the path indicated by the arrows the filter material 9 on · At the perforations 6 of the pipe, the medium then exits again in a purified form and arrives in the depicted Fall through the nozzle 3 to the outlet.
