Description

The utility model relates to the field of transport engineering, namely, to movable flexible pipes designed to connect a pipeline when transporting a fluid.

Known angular reinforced sleeve-compensator for transporting fluid through pipes, containing a sealing rubber layer, a power rubber-cord frame, a cover layer and clamping mechanisms. On the wall of the expansion sleeve in the area of the outer bending radius, in the sector from 60 to 120 ° in cross section, additional dome-shaped recesses are made (see patent No. 2519535, IPC F16L 43/00, F16L 51/04, publ. 10.06.2014).

The closest to the claimed technical solution in terms of the set of essential features and the achieved technical result is the angular pipe of the air filter, consisting of two parts, connected by welding, while at its ends there are annular protrusions, and at the junction of the two parts, protrusions are made, which, when the parts are mated together they form a protective pocket (see patent No. 189405, IPC F16L 13/02, publ. 05/21/2019).

The known solutions in most cases have insufficient operational reliability associated with gas turbulence and the resulting resistance in the system, and the impossibility of compensating for the geometric movements of the operating system.

The task to be solved by the proposed technical solution is to increase the operational reliability.

To solve this problem, in the corner pipe of the air filter containing an arcuate section, connecting ends, pockets, the arcuate section is made smoothly tapering, while the ends have holes of different diameters, the pockets are made on the inner sides of the ends, in addition, the arcuate section contains a grid of triangular cross-section ribs ... In a particular case, retaining collars, restraints for the installation of fastening clamps and lead-in chamfers are made at both ends.

The set of distinctive features, consisting in the fact that the arcuate section is made smoothly tapering, while the ends have holes of different diameters, the pockets are made on the inner sides of the ends, in addition, the arcuate section contains a grid of triangular ribs, allows to reduce the air discharge in the air intake system and eliminate additional resistance to the movement of gases up to the critical clogged state of the air filter, thereby increasing operational reliability.

The claimed technical solution is illustrated by drawings:

in fig. 1 shows a corner pipe of the air filter, side view;

in fig. 2 - the same, top view;

in fig. 3 - the same, left side view;

in fig. 4 - section a-a in Fig. 2.

The corner pipe of the air filter contains an arcuate section 1, made smoothly tapering, connecting ends 2, 3 located in different directions at an angle from each other, and having holes of different diameters. At both ends 2, 3 there are retaining flanges 4, stops 5 for installing fastening clamps and lead-in chamfers 6 to facilitate the installation of the corner pipe, reliability of connections with the pipelines of the system. Also on the inner sides of the ends 2, 3 there are pockets 7, which, when connected to the pipeline elements, form a monolithic structure. The arcuate section 1 contains a grid of ribs 8 of triangular cross-section, which increases the rigidity of the pipe and allows you to maintain its shape when a vacuum occurs during operation.

The corner pipe of the air filter is technologically advanced by design and can be made of rubber material by injection molding. Execution of the branch pipe made of rubber-technical material makes it possible to compensate for vibration effects and geometric displacements of the system. Also, the branch pipe can be made from modern materials using additive technologies.

The air filter elbow is installed in the vehicle's air filtration system. With ends 2 and 3, the branch pipe is connected using clamping clamps, respectively, with the air line branch pipes of the air filter and the inlet branch pipe of the compressor stage of the turbocharger.

When the vehicle air filtration system is operating, the air from the air filter through the end 2 and the arcuate section 1 is directed to the end 3 to be supplied through the pipeline to the inlet to the turbocharger of the internal combustion engine.

The claimed technical solution improves operational reliability.

The claimed technical solution is possible for implementation on standard technological equipment.
