FIG. 1 - Air filter assembly of an internal combustion engine, a general view in isometric view;

FIG. 2 - the same adapter in isometry;

FIG. 3 is the same, in section of FIG. 1, a top view in isometric view is rotated.

The air filter assembly of the internal combustion engine contains a housing 1 in which two filter blocks 2 and 3 are placed. The housing 1 is closed by a cover 4, which is removable for installation and removal of the filter blocks 2 and 3 from the housing 1. The housing 1 also includes an inlet pipe 5 for connecting with the elements of the air purification system, two exhaust pipes 6 and 7, which are located on one side of the housing 1 and are connected in the housing 1 with filter units 2 and 3, the presence of which allows to increase the dust absorption of the filter and its re urs. In addition, the exhaust pipe 6 is connected to the pipe 8 through a sleeve crimped by a band clamp, and the exhaust pipe 7 includes a pipe 9, which is combined with the pipe 8 of the exhaust pipe 6 with the formation of the combined pipe 10 leading to the engine. The inlet pipe 5 is located on the upper surface of the housing 1 and is equipped with an adapter 11, designed to separate moisture in front of the air filter from the air flow entering the system. The adapter 11 is made concave and installed at an angle to the inlet pipe 5. This location of the adapter allows you to reduce the resistance in the mode of operation of the filter, and, therefore, increase reliability. The adapter 11 has an outlet pipe 12 and an inlet grate 13, which is made with water-retaining straps 14 and holes 15 for the passage of collected water. The inlet grate 13 is involved in the process of moisture retention from the supplied air to the filter and reduces the load on its filter blocks, thereby increasing reliability. The outlet pipe 12 at the base of the connection with the inlet pipe 5 has slots 16 for crimping and a reliable tight connection using a tape clamp with the inlet pipe 5. On the outlet pipe 12 of the adapter 11 with the aid of clips 17, a spacer 18 with a water collecting pipe 19 is installed, at the end of which there is a nipple valve 20 fixed by a worm clamp 21. On the outer surface of the inlet grate 13, a ledge 22 is made for reliable fixation on the adapter 11 of the connecting element 23 of the air purification system, which allows exclusion be penetration of ambient air to the inlet adapter. Between the spacer 18 and the inlet 8, a sealing ring 24 is located for their tight and reliable connection, which eliminates the possibility of air and water entering the moisture of the lattice.

The air filter device operates as follows.

On an operated car, during operation of the internal combustion engine, when water enters in the form of precipitation with air entering the air purification system, it is sequentially separated first in the air intake part of the system, then when it enters adapter 11 of the inlet grille 13, namely, moisture retaining ones straps 14. Gathering near the holes 15, the water is directed into the cavity formed by the outlet pipe 12 and the spacer 18, after which the water flows through the moisture collection pipe 19 to the nipple valve 20, through which when the engine is stopped or when a certain amount of water is collected, it has the ability to merge into the environment. Further, the air separated from the water enters the air filter, where in its filter blocks the mechanical particles and dust are cleaned. That is, the water that could get into the filter blocks is delayed by the strips 14 of the inlet grate 13 and is discharged into the nipple valve 20, thereby increasing the reliability of the filter blocks 2 and 3. The purified air is sent to the internal combustion engine through a connecting pipe 10.

The claimed technical solution allows to ensure the operational reliability of the design.

The claimed technical solution meets the requirement of industrial applicability and is possible for implementation on standard technological equipment using previously mastered technologies.
