    A supercharger set for internal combustion engines comprising two turboblowers the two axes of which being mutually perpendicular. The high-pressure turbine is mechanically coupled to the high-pressure compressor, whereas the low-pressure turbine is mechanically coupled to the low-pressure compressor. A single casing is used for the egress of the gases from the high-pressure turbine and their ingress into the low-pressure turbine.

    DEVICE FOR SUPPORTING INTERNAL COMBUSTION ENGINE
     The invention relates to mechanical engineering, namely engine building. in particular, to a turbo-compressor group for pressurizing the engine .5
    A device for supercharging an internal combustion engine is known, comprising first and second stage turbo compressors, in which the turbines of a first stage turbocompressor are connected by an inlet to the exhaust manifold of the engine and a kinematically associated compressor connected to the outlet; 15 engine intake manifold, and y - the second stage turbocharger. The turbine is connected by an inlet through a common intermediate casing to the exhaust port of a turbine of a turbo-20 first-stage compressor and a kinemati- cally connected compressor. connected by its outlet to the inlet of the compressor
    turbocharger first stage through the connecting pipe 11.
    However, in the known devices, the axes of the turbo-compressors are parallel or lie on the same line and therefore, the dimensions of these devices are quite large.
    The purpose of the invention is to increase the compactness.
    To achieve this goal, the turbochargers are located with their axes intersecting at right angles.
    Air coolers can be installed in the intake manifold of the engine and in the connecting pipe of the compressors.
    FIG. 1 shows a diesel-type internal combustion engine with the proposed pressurization device, a general view of FIG. 2 is a section through turbo-compressors.

    Claims (2)
    [1]
    The proposed device 1 is installed on the engine 2 and consists of two stages, formed by turbo-compressors 3 and 4, working on diesel exhaust gases and installed in series. Turbine 5. .tour booster compressor first stage; It is connected with its inlet to the exhaust manifold 6 of the engine. The compressor 7 is kinematically connected with it by means of a common shaft 8. The impeller 9 of the turbine and the working rim 10 of the compressor, together with the shaft 8, form the rotor of the turbo-compressor 4 The turbine 11 of the second-stage turbo-compressor is connected by its inlet to the outlet of the turbine 5 and is kinematically connected with a low-pressure compressor 12, the outlet of which is connected to the inlet of the compressor 7 through the connecting joint of BRK 13-Shaft 14 and the impeller 15 of the turbine 11 mounted on it, and the compressor working rim 16 of the bottom Whose pressure 12-form the rotor of the turbo-compressor spring 3- The outlet of the turbine 11 and the inlet of the compressor 12 are in communication with the atmosphere, and the outlet of the high-pressure compressor 7 is connected to the inlet manifold 17 of the engine 2, the axes of the turbo-compressors are perpendicular, i.e. The turbo-compressors are located with their axes intersecting at the right angle. For connecting the inlet of the low-pressure turbine 11 to the outlet of the high-pressure turbine 5, an intermediate case 18 common to the turbo-compressors is provided. In the connecting pipe 13 an air cooler 19 is installed for intermediate cooling of the air between the compression stages and An air cooler 20 is installed in the intake manifold 17 to cool the compressed air before it enters the engine. Shown in FIG. 1 turbo weed group located on one. of the ends of the engine and only one of the air coolers, designed for the final cooling of the air cooler 20, is mounted on the opposite end. During engine operation, exhaust gases are driven into rotation by an impeller 9 of a high-pressure turbine 5. Through the shaft 8, the turbine drives the working rim 10 of the high-pressure compressor 7 to rotate. The gases exhausted in this turbine enter the turbine 11 and the impeller 15 is set in rotation, which through the shaft 14. drives the working rim 16 of the low-pressure compressor 12 into rotation. From the turbine 11, exhaust gases enter the atmosphere through the pipe 21. At the same time, air is drawn from the atmosphere through the pipe 22 into the working rim 1b of the low-pressure compressor 12. The air compressed in it through the connecting pipe 1 3 enters the high-pressure compressor 7 and, after compression, enters the engine inlet manifold 17 and then into the engine cylinders either directly or through the air cooler 20. The location of the pipe compressors with the axes intersecting at a right angle allows to provide a two-stage engine boost according to the proposed scheme with the maximum compactness of the pressurization device. Claims T. An apparatus for pressurizing an internal combustion engine, comprising first and second stage turbo compressors, in which a turbine of a first stage turbocompressor is connected by an intake port to the engine exhaust manifold and a kinematically associated compressor connected to the engine inlet manifold, and the second compressor kinematically connected to it. stage turbine is connected to the inlet through a common intermediate case to the outlet of the turbine of the turbocompressor of the first | cally an associated compressor is connected to its outlet to the inlet of the first stage turbocharger compressor through a connecting pipe, otlichayusche.es in that, in order to increase compactness, turbochargers are arranged with their axes crossing at right angles.
