    An improved filter element assembly for use in an air cleaner on an internal combustion engine comprises a perforated liner. A replaceable filter element comprising a pleated filter medium is releasably coupled to the liner. A safety sleeve assembly is interposed between the filter medium and the liner. An outer liner surrounds the filter medium and exerts a radially inward force thereon to bias the pleats into engagement with the liner. The filter element assembly can be reconditioned when the filter medium becomes used with a replacement kit which includes a new filter element, safety sleeve assembly, and outer liner. The used filter element assembly is disassembled and the worn components thereof replaced with the new components of the kit. The filter medium is expandable from a collapsed cylindrical form in which the filter element is shipped to an expanded conical form for use during filtering operations.

In addition, the filtering element is provided with a protective taper sleeve with a ring gasket on a larger base placed in the liner and slanted from a porous elastic material, the filter is made of paper, the casing is made with an opening for accessing the filter element and provided with a lid. Figure 1 shows the air cleaner. Fig. 2 is a view along arrow A in Fig. 1; in Fig. 3, the outer shell; 4 shows a filter curtain; figure 5 - internal perforated liner; 6 is a safety sleeve; 7 - section B-B in Fig. 6; - in Fig. 8 - an overlap outer shell connection assembly / in Fig. 9 - a end-to-end shell connection node; figure 10 - node 1 in figure 1; Fig. 11 is a container with spare parts for the filter element. The air cleaner has a metal body 1, which is cylindrical and includes an internal filter chamber 2, a suction pipe 3 and an exhaust pipe 4. The body 1 is detachably or fixedly connected to the body of the truck. The air intake duct 3 is in communication with the flowing medium with ambient air, and the air exhaust duct 4 1 is attached in an appropriate manner to the air inlets of all cylinders in the internal combustion engine (not shown). One end of the housing 1 has a protruding outward or annular mounting flange or retaining ring 5, koTopoe passes around the entire periphery of the housing 1. This end of the housing is open, but adapted to be closed with a removable bolt or lid 6. The lid b has an annular shoulder or protrusion 7, which is located opposite the retaining ring 5. The ring seal 8 is installed between the protrusion 7 and the ring 5. The Row of bolts is loosely tensioned. through the nuts, connects the ring 5 and the protrusion 7 detachable connection. When the cover 6 is open, the filter element 9 can be removed from the housing 1, therefore it is necessary. Install the air cleaner in such a way that the cover 6 is easily accessible to replace the filter element 9 without detaching the body 1 from the vehicle body (not shown. The filter element 9 includes an internal conical perforated liner 10. The internal liner 10 is made with a V-shaped casing or cup 11 The cup 11 contains a chamber 12. The other end of the inner liner 10 has, on a smaller base, an outer annular locking shoulder 13. The inner liner 10 is made of metal, high plastic (or other material). This can be used again. The filtering 3J eMeHT 9 includes a safety sleeve 14 placed on a liner 10, which is made of a porous fabric, preferably of a wool type fabric made of viscose and polystyrene, and has an annular gasket 15 on a larger base. sleeve 14 is fixedly attached to the annular gasket 15, made of expanded urethane, which includes a radially protruding flange 1b and axially protruding flange 17. The flange 17 has a groove in which m boltsshy digidetr adhesive attached safety sleeve 14.
    The filter curtain 18 is made occate and can take a conical or cylindrical folded shape, identical to the shape of the inner liner 10. The filter curtain 18 has an end cap 19 made of molded polyurethane and attached to a smaller diameter curtain. The end cap 19 has an axial groove 20 that repeats the shape of the liner 10. In the groove 20, an annular locking groove 21 is provided in which the locking collar 13 located on the liner 10 is placed.
    The filter curtain 18 can be made of paper and similar materials that can be chemically treated to acquire filtering properties.
    The filter element 9 includes a conical outer shell 22. The smaller and larger base of the safety insert 10 are respectively smaller and larger bases of the filter curtain 18. The outer shell 22 is made of foamed urethane, has open pores and has elasticity. The formation of the outer shell 22 is carried out by rolling the sheet into a conical shape and joining the edge along butt-forming or overlapping. When joining, overlapping edges are made thinner, the joint is made by welding, but any other properties of the joint can be used.
    The assembly of the filter element 9 is realized as follows.
    The safety sleeve is worn on the inner liner 10f while it covers the inner liner 10 and May have a free end 23, made in a closed or open form. In any case, the end 23 is inserted inside the inner liner 10. After placing the safety sleeve 14 on the inner liner 10, put the outer shell 22 around the filter curtain 18 when the curtain is in the folded state, after which an internal liner 10 is inserted inside the filter curtain 18 a protective sleeve 14 spaced on it. Thanks to the conical shape of the inner liner 10, as it is moved, the folds of the filter curtain 18 are straightened to those; until the filter curtain has a conical shape corresponding to the shape of the inner liner 10. The inner liner 10 moves
    along the filter curtain 18 until the locking flange 13, engages with the inner surface of the annular locking groove 21 on the end cover 19, exactly matching it. The upper end of the filter curtain 18 is fully expanded and placed inside the chamber 12 of the end cup 11, usually adjacent to. a radially protruding flange 16 of the annular gasket 15. The radially protruding flange 16 of the gasket 15 seals the upper end of the filter curtain 18 and is breathable relative to the end CIR 11.
    The outer shell 22 is arranged with a voltage that causes a radially inward force on each of the folds. This force leads to engagement of the warehouse. The inner dock 10, in this case, it tends to ensure that all the folds are evenly spaced around the entire periphery of the filter by the curtain 18, and also serves to dampen any movement of the folds that may occur from vibration or air pressure fluctuations on the folds.
    The assembled filtering element is installed in the housing 1, the hatch 6 is removed at the same time, the filtering element is inserted with a larger diameter cone and closed with an end cap. When the nuts on the end cap are tightened, the end cap 6 is engaged with the end cap 19. The outer surface of the cup 11 on the inner liner 10 has an o-ring 24, which engages the end steak of the housing 1 when the cap 6 is set to form airtight seal The filter elements are packaged for transport to container 25.
    The operation of the air purifier is carried out as follows.
    Air cleaner body 1 enters the air through the suction pipe 3, the outer shell 22, the filter curtain 18, the safety sleeve 14, the inner plug 10 and then finally out through the exhaust pipe 4. The exhaust pipe 4 is installed along the same axis as the filter element 9 ..
    When the vehicle is moving, the air cleaner, fil1 / rubbing element 9 is installed on the filter, filters the combustion air entering the internal combustion engine of the truck. As the filter element 9 is dirty, the latter is to be replaced by removing the cover and uncoupling the 10, 14, 18 and 22.
    When replacing the filter element 9, all parts are replaced with the exception of the inner liner 10, which can be reused. Replaceable parts 14, 18, and 22 are included in the replacement kit, which are shipped in shipping container 25. The reassembly method is similar to the assembly procedure described by BfcBue.
    The filter element 9 has advantages over the known ones, since the filter curtain can take on a cylindrical shape for transportation, while the size of the shipping containers 25 for the replacement kit can be greatly reduced. The weight of the kits is reduced by the absence of an inner liner 10.
    Great savings in shipping and storage costs for replacement kits are achieved.
    The advantage of this air cleaner is that the outer shell 22 acts as a pre-filter, increasing the service life of the filter curtains 18.
