- an insoluble liquid-tight connection between the return check valve and the filter element is formed.
- the filter element has end plates, which are arranged on the end faces of the folded filter medium. These end plates are preferably made of a thermoplastic material, wherein the center tube or support tube for the filter medium is formed directly on the end plate.
- Figure 2 shows a section through the lid of Figure 1
- FIG. 4 shows an alternative embodiment of the replaceable filter in FIG.
- Figure 5 shows the detail view of a lid in a further variant.
- a replaceable filter 10 is a perspective view in partial section
- the replaceable filter 10 has a pot 11, a lid
- the pot 11 is in its upper Randbe ⁇
- the lid 12 has a contour which is formed as a circumferential ring 15.
- the ring 15 is surrounded on its outer circumferential surface 16, its upper end face 17 and its inner annular surface 18 of the upper edge portion 14 of the pot 11.
- a part of the pot 11 bears against a lower end face 19 of the lid 12.
- the lid 12 has a plurality of circumferentially spaced inlet openings 20, which are configured oval.
- the cover 12 has a centrally disposed outlet 21.
- the filter element 13 has a zigzag folded filter medium 22, which is connected at its upper end side with an end plate 23.
- the filter medium 22 has a further end plate 24.
- the lower end plate 24 is formed integrally with a support tube 25.
- the support tube 25 is permeable to the liquid to be cleaned, and it does not generate any appreciable pressure loss.
- a bypass valve 26 is arranged in the lower region of the support tube 25, a bypass valve 26 is arranged.
- the bypass valve 26 is formed by a cylindrical portion 27 in the support tube 25, wherein in the cylindrical portion 27 through openings 28 are provided.
- the passage openings 28 are closed by an elastic piece of tubing 29.
- the lid 12 has a seal holder 34, which is fixed in the spot welding method on the lid 12.
- the seal holder 34 is formed by a thin plate with a mounting surface 35 and a support surface 36. At the attachment surface 35, the spot welds are created.
- the lid 12 is shown in Figure 1 in section. Identical components are provided with the same reference numerals.
- the lid 12 is as formed urgeformtes sheet metal part, wherein the outlet 21 is deep drawn.
- the inlet openings 20 are easy to produce by punching.
- the replaceable filter 10 is shown according to Figure 1 in an alternative embodiment. Identical components are provided with the same reference numerals.
- the lower end plate 24 is performed separately from the support tube 25.
- the bypass valve 26 is formed directly on the lower end plate 24.
- the support tube 25 rests with its ribs 38 on the highest area of the bypass valve 26.
- the ribs 38 are designed analogously to the support tube 25 shown in Figure 1 as crossing ribs 38.
- the upper end plate 23 is designed such that the sealing surface 32 of the return-blocking diaphragm 31 is supported radially circumferentially. Thus, the sealing surface 32 between the outlet 21 and a portion of the upper end plate 23 is sealingly pressed.
- the support tube 25 contacts the underside of the upper end plate 23 and the end face of the lid 12, whereby the axial position is defined in the pot 11.
- FIG. 4 shows a replaceable filter 10 according to FIG. 1 in a further alternative embodiment. Identical components are provided with the same reference numerals.
- the lid 12 is formed such that between the inner annular surface 18 and a bead 39, a seal holder 40 is formed. In this one lumpy formed by geometries of the lid 12 seal receptacle 40, the seal 37 is inserted.
- the bead 39 is formed by a forming process of the lid 12 in the form of a shaft.
- the outlet 21 is formed as an annular collar, which projects into the interior of the pot 11.
- an internal thread 41 for fixing the replaceable filter 10 is provided on a connecting piece inside the annular collar.
- the internal thread 41 can of course also be attached to the cover 12 of the preceding figures.
- the replaceable filter 10 shown in Figure 4 differs from the preceding figures, characterized in that the end plates 23, 24 are annular, wherein in the upper end plate 23, a holder 42 is plugged sealingly for the return flow diaphragm 31.
- the holder 42 has a collar 43, on which the non-return membrane 31 is attached.
- the holder 42 has a Einsteckrand 44, which bears sealingly against the end plate 23.
- supporting elements 45 are provided, which are arranged distributed on the circumference of the holder 42.
- the bypass valve 26 ' has a valve housing 46, which is inserted sealingly into the lower end disk 24 via a plug-in collar 50. Furthermore, the valve housing has a cylinder region 51, Wel- rather protrudes into the interior of the filter element 13.
- a valve seat 52 is formed, which on the one hand forms the correspondence surface to a valve plate 53 and on the other hand, a support surface for a spring 54.
- the valve disk 53 is fixed to the spring 54 with three valve feet 55 (due to the sectional view only one foot is completely visible), so that the valve disk 53 lifts off the valve seat 52 if the pressure on the raw side of the filter element 13 is too great.
- support elements 45 are distributed around the circumference. Furthermore, 13 support feet 56 are provided for the axial positioning of the bypass valve 26 'and the filter element, which are supported on the bottom of the pot.
- Figure 5 shows a perspective view of the lid 12 without further additional components.
- the cover 12 To avoid the spinning of the pot 11, which surrounds the lid with its flange, are arranged on the cover 12 evenly distributed around the circumference retaining lugs 60, 61, 62, 63, 64, 65, 66, 67. These are impressions that lead to the fact that after flaring the pot 11, this is enclosed in the form of a locking fit with the retaining lugs in the region of its collar. This allows a high torque from the pot to be transferred to the lid.
- the lid 12 may also be provided with a knurling in the crimping become. This knurling ensures that after flanging the pot 11, a continuous, reliable fixation of the pot 11 on the lid 12 takes place. The spinning of the pot 11 on the lid 12 is thus avoided.
