Abstract

The invention makes it possible to improve the manufacturability of the air cleaner. The integral pallet (P) 5 and installed in the protruding base 7 of its bottom 6 bath 8 are made as a single part. plastic w. The cavities of the cavities 13 forming the guide cone 9 and the radial ribs 12 enter into the interior of the P 5. The ejection section 10 is made in the form of a one-sided spherical layer extending from the base inside the P of the E with uniformly spaced above the base ejection openings 11. Such an embodiment of the air cleaner increases its strength x-ki due to the absence of mechanical power elements, mutually rubbing surfaces and fastening elements, orientation of clamps. Eliminates the need to remove the wash bath. In addition, the stiffness of the carbonate and, at the same time, the flexibility of the ejection stage during oil blows, increases. 3 il. i (L

The invention relates to mechanical engineering, mainly to engine building, in particular to air cleaning devices for internal combustion engines.

The aim of the invention is to improve the manufacturability.

FIG. 1 shows the proposed inertial-.VI and ate YANY and air cleaner, cut; in fig. 2 pallets with oil

bathroom (in isometry, with a hole); in fig. 3 - injection mold for the manufacture of an oil pan with a bath, a slit.

The air cleaner consists of Cornus 1, in which the filtering elements are installed. 2. The KO | iiyce contains the pent) alloWable water, the slab 3 and the side discharge pipe 4. To the lower part of the cornus 1 is attached. base pallet 5, and in the bottom 6 of the top 1, the bottom 7 of the base has a large nanometer 8 with the directional head 9 and b) the same som K) with uniformly): m:) with openings 11. The inner part 1 of the oil bath 8 is equipped with radiator 11 edges 12. The lined oil pan 5 and the oil to the bath 8 are made in one I as a single piece of plastic, with the base 7 of the pallet 5, the guide cone 9 and the radial fins 12 of the bath formed by the depressions 13 that go inward into the pallet by the erection, and the ejection section from 10 in 1.

But the spring-loaded mark 18, with its support 26, acts on the packs 27 of the unclamping segments 21, which rotate on the axles 22 and release the undercut in the oil pan and are removed from the part upon further opening, when the mechanism 31 engages and releases the plate 29 removal, and ti 30, choosing a free wheel, drop the item together with the central pusher 28 from the stop of the automatic thermoplastic acting on the shank 32.

In the case of a closure of the mold, the compressing element 25 returns the pressure segments 21 to the grooves 20 of the sign 18, at which time the latter is pressed into the movable part 17. It affects the new wedges 24, the movable unors 23 are fixed, and the turn supports the expansion segments. The form is ready for pouring.

the air cleaner works as follows. The air node is exposed to the vacuum action created by the engine during the intake stroke and enters the pipe 3 and moves downward along it. At the exit of the pipe 3, the air, which is in contact with the oil in the oil bath 8 and 1 donna 5, and abruptly changes its direction, moves through the filter elements 2, the outlet pipe 4, to the inlet nozzle 4. Hector engine.

ripii operation of the engine together with the truck, acting on the air cleaner to (x: fumes and vibrations from the tractor body and 11 pulsing air flow create bursts of oil in / under the air, which dipamically affects the oil bath and sump, performed as a single Parts made of plastic allow an increase in the air-to-dust performance, 11b, since the structure as a whole has higher strength characteristics. It does not have any mechanical force, which is mutually rubbing on the surface. The load is unloaded and greatly simplified due to the absence of fasteners, clamps, and orientation.

Technological servicing of the unit as a whole is because it is not necessary to remove the bath and remove it after washing, and then install it.

Due to the fact that the base of the noddon, the directions of the cone and the radio, the ribs are formed into the cavity of the cavities of the cavities inside the pallet, the rigidity of the structure increases, and you get an ejection hole in the interior of the base from the base in the middle of the wall) ujapo s, then it provides flexibility during oil blows, which ensures durability and reliability in operation, and prevents crack formation.

The use of an air purifier of this design will reduce laboriousness and simplify the construction.
