- the housing consists of a housing pot and
- the housing cover is designed such that several ver ⁇
- the housing pot is made by forming operations from a sheet metal
- the object of the invention is ready alternately configured replaceable filter
- the inventive replaceable filter is for cleaning liquids
- the replaceable filter has a housing with one or more Ein ⁇
- the Housing is formed by a pot and a lid, wherein the pot is sealingly connected to the lid.
- the pot and the lid each consist of a metal sheet, which is mechanically deformable.
- the pot has a pot bottom and, adjoining the bottom of the pot, preferably cylindrical trained pot wall. In the pot bottom openings are arranged, which are formed as inlets and outlets. The inlets and outlets are punched out of the bottom of the pot after the forming process of the pot or worked out by a span-lifting operation out.
- the lid is designed as a liquid-tight sheet metal part without openings.
- a prefabricated lid can be produced from a sheet-metal disk, which lid can be sealingly connected to the pot.
- the lid may preferably be sealingly crimped with the pot.
- the bottom of the pot has stiffening beads, which are provided for mechanical stiffening of the housing.
- the stiffening beads are preferably arranged between openings which form the inlet for the liquid to be cleaned.
- the stiffening beads are formed as bulges with a substantially same wall thickness as the rest of the pot bottom. The bulges may have convex outward or alternatively concave projecting into the interior of the housing.
- the number, length and position of the stiffening beads depends on the achievable necessary stiffening. The arrangement of the stiffening beads, a mechanical deformation of the pot bottom can be prevented, which can lead to leaks in the assembled state.
- the stiffening are arranged in a star shape star shaped on the bottom of the pot, wherein the stiffening beads extend only over a portion of the center of the pot bottom to the outer periphery.
- the pot bottom in these areas, which are prone to undesirable mechanical deformations, an additional stabilization.
- an inlet opening for the liquid to be cleaned can be arranged between two adjacent stiffening beads.
- the pot bottom is optimally supported in the region of the largest material weakening.
- the pot bottom has a sealing bead, in which a seal can be inserted.
- the sealing bead surrounds all the inlet openings of the pot bottom.
- the sealing bead is disposed near the outer periphery.
- the seal is vulcanized to the pot bottom.
- the Seal be introduced both in a sealing bead, as well as applied to a suitably designed edge.
- the housing is designed in the form of a pressure vessel.
- the pot has a cylindrical peripheral surface and an outwardly curved pot bottom.
- the cover is also arched outward in the mounted state.
- a threaded insert is inserted into the bottom of the pot, in particular pressed, so that the replaceable filter can be easily mounted on a mating thread.
- the lid is formed as a collection area for separated from the liquid to be cleaned other liquids.
- the lid, which closes the pot down, may have a special shape in which the liquid collects and is discharged from there.
- the filter element has a bypass valve which opens in the operating conditions in which too little liquid flows through the filter medium.
- operating states are z. B. in a dirty filter medium or at

- Figure 1 shows a replaceable filter in perspective view in partial section
- Figure 2 shows an alternative sealing ring in a perspective view.
- a replaceable filter 10 is a perspective view in partial section
- the replaceable filter 10 has a pot 11 and a De ⁇
- the pot 11 together with the lid 12 a housing, which essentially represents the outer geometry of the replaceable filter 10.
- the pot 11 is connected via a liquid-tight flange 13 with the lid 12.
- the pot 11 has in this case with its open end down, where the lid 12 closes the pot 11.
- the pot 11 has a closed cylindrical peripheral region 14, which merges into a top bottom 15 in the upper region of the pot 11.
- a sealing bead 16 is arranged, on which a seal 17 is plugged or vulcanized.
- an outer ring 18 is provided, which prevents the seal 17 escapes radially outward in the assembled state and thus causes leaks.
- the outer ring 18 may be welded or glued to the pot 11, whereby it is permanently connected to the pot 11.
- a plurality of distributed inlet openings 19 are provided, through which the liquid to be purified can flow into the replaceable filter 10.
- stiffening beads 20 arranged in a star shape are arranged on the bottom of the pot, which bulge concavely into the interior of the replaceable filter 10.
- the bottom of the pot 15 has a centrally arranged outlet opening 21 for the cleaned liquid.
- the outlet opening 21 is formed by a pressed-threaded insert 22, with which the replaceable filter 10 to a suitably designed Flange (not shown) can be screwed.
- the outlet opening 21 may be formed by a deep-drawn and threaded pot bottom area.
- a return-blocking membrane 24 is arranged, which seals the filter element 23 relative to the threaded insert 22.
- the filter element 23 has a filter medium 25, two end plates 26 and a support body 27.
- the support body 27 has ü- an upper stop 28, which supports the filter element 23 in the axial direction of the threaded insert 22.
- the support body 27 has a valve region 29, which projects into the interior of the annular closed filter medium 25.
- the valve region 29 has a cylindrical region with passage windows 30, which are closed by a hose valve 31.
- the hose valve 31 is lifted off the windows 30, so that the liquid can flow untreated from the raw side onto the clean side arranged inside the filter element 23.
- the lower end plate 26 of the filter element 23 sealingly connects to the support body 27, whereby leakage in this area can be prevented.
- a sealing ring 32 is shown, as it can be used as an alternative to the seal 17 of Figure 1.
- the sealing ring 32 adds over a frame 33, which on the one hand the outer geometry for the sealing material 34 and on the other hand stiffening structures 35 bi.
- the stiffening structures 35 are formed analogously to the stiffening beads 20 according to FIG. 1, the stiffening structures 35 being applied convexly to the pot base 15.
- the stiffening structures 35 can be welded to the bottom 15 of the pot.
- plan connection areas 36 are provided on the bottom 15 of the pot.
