Description

FIELD OF THE INVENTION The invention relates to engine-making, namely to devices for cleaning air of an internal combustion engine (ICE).

Known air cleaner for internal combustion engines, comprising a housing with inlet and outlet nozzles, a filter element and an elastic sealing gasket placed between the housing and the end of the filter element (auth. No. 868082, class F 02 M 35/02 published in 1981) .

A disadvantage of the known air cleaner is the complexity of the design due to the need to impart a special rigidity to the filter element due to

outer and inner perforated frames, as the mechanical seal of the filter is carried out by axially tightening the housing with a cover. Such an air cleaner design is unreliable in operation, since axial tightening loads deform the filter, deform and age the gaskets when vibrating from the engine running, dust is bursting between the face sealing gaskets.

In the process of working in dusty conditions, the filter is clogged and thrown out along with the metal frames, which leads to irretrievable sweat2

re rolled metal, because the filter is made of special paper and its front parts are filled, for example, with epoxy resins together with metal frames,

An air cleaner for internal combustion engines is also known, comprising a housing with a central outlet branch pipe in a removable bottom, a ring filter element disposed concentrically therein with an end plate overlapped with an end plate, an elastic sealing gasket placed between the removable bottom and the end of the filter element, and a device for connecting the removable bottom to the housing (av.ev, No. 673751, CL F 02 M 35/02 publ. 1979).

The disadvantage of this air cleaner is also the need for an axial tightening in order to be able to make the mechanical seal. Since the forces are sufficiently large, the filter element is installed in metal frames, which are ejected after flanging the filter. This leads to a loss of metal. During the operation of such a filter, the attachment device may loosen: firstly, due to vibration, the thumbscrew is unscrewed, which attracts the filter element to the removable bottom through an elastic gasket, secondly, the elastic gasket loses its properties from prolonged loads and dust passes into the engine intake tract, mine filter element, which creates a generally unreliable in his work.

The aim of the invention is to save metal and improve the reliability of the air cleaner.

For this purpose, in an air cleaner for an internal combustion engine, comprising a housing with a central outlet pipe in a removable lid, an annular filter element with an end plate overlapped with an end plate, an elastic sealing gasket placed between the removable lid and the end of the filter element, and a device for connecting the removable lid with the body, the end plate is made of an elastic material and is made with a filter element, which is made completely with an elastic sealing gasket, and the device for and removable cover is formed with a housing provided on their ends with flange returns concave profiles of the yoke and a V-shaped sectional profile, clamping a peripheral portion of the elastic sealing gasket between the end flange returns.

Such an air cleaner design allows the filter element to be unloaded from power loads, to remove the metal frames and to ensure through this

economic effect. The reliability of such an air cleaner is high, since the filtering element is not affected by the force loads from the backslash and does not destroy it.

FIG. 1 shows the proposed air cleaner, a longitudinal section; in fig.

2- section of the filter element with the peripheral part of the elastic sealing gasket in the section.

The air cleaner comprises a housing 1 with a central outlet pipe 2 in a removable cover 3, a ring filter element 4 concentrically arranged therein with an end plate 6 blocked by an end 6, an elastic sealing gasket 7 placed between the removable cover 3 and the end 8 of the filter element 4, and removable cap connections

3c with the housing 1. The face plate 5 is made of an elastic material and is made integrally with a filter element 4, made integrally with an elastic sealing gasket 7. A device for connecting the removable cover 3 with the body 1 is formed by bidding on them

flanging 9 and 10 with concave profiles and a collar 11 with a V-shaped section section, clamping the peripheral part 12 of the elastic sealing gasket 7 between the end flanging 9 and 10. The input

pipe 13 is located on the side surface of the housing 1.

The air cleaner works as follows

Engine suction air through

the inlet 13 enters the filter element 4, is cleaned and through the outlet central nozzle 2 enters the engine inlet duct.

Since the peripheral part 12 of the gasket 7 is clamped between the flanges 9 and 10 of the removable cover 3 and the housing 1 by the collar 11, the filter element 4 is completely unloaded from

tension loads, which makes it possible to remove reinforcing steel perforated sleeves from the outside and inside of it. The absence of temporary power loads maintains the integrity of the filtering element 4 with the end plate 5 and the elastic sealing gasket 7, which are made of an elastic material and are filled with a joint filtering element. Special paper is used as filter material.
