Description

This invention relates to a compressor industry, in particular to a centrifugal supercharger. A centrifugal supercharger is known, comprising a housing, an impeller mounted therein, a separation chamber communicated at the periphery with the internal cavity of the housing and a bypass pipe through a pump with a sleeve cavity, the impeller and the pump being connected to their actuators 1. However, this centrifugal supercharger does not provides high reliability of its work due to the installation of drives on the shafts of the impeller and the pump. Closest to the proposed technical essence and the achieved effect of a centrifugal supercharger, comprising a housing, an impeller mounted therein, made in the form of a hollow bushing with radial nozzles interconnected along the periphery by means of a separation chamber placed in an annular channel communicated with a bypass connection using a sleeve, a combustion chamber in communication with the separation chamber through air intake and hydraulic pipelines, and perforated tubes located in the radial s nozzles communicated with the atmosphere and 2. However, such an embodiment of a centrifugal supercharger does not ensure high reliability of its operation due to the insufficiently effective design of the separation chamber. The purpose of the invention is to increase the reliability of the centrifugal supercharger. This goal is achieved by the fact that in a centrifugal supercharger comprising a housing, an impeller mounted therein, made in the form of a hollow bushing with radial nozzles interconnected along the periphery by means of a separation chamber placed in an annular channel communicated by a bushing with a bushing cavity, the combustion chamber communicated with the separation chamber by means of air intake and hydraulic pipelines, and perforated tubes located in the radial nozzles and communicated with the atmosphere, The radial duct is made in the housing, the radial nozzles through one are plugged on the side of the sleeve, and the air intake ducts are placed in the filled nozzles, the perforated tubes are unglued, and the outer surface of each radial nozzle has a pterygoid profile. FIG. 1 shows a centrifugal supercharger on the suction side; in fig. 2 is a section A-A in FIG. one; in fig. 3 shows the node j in FIG. 1. The proposed centrifugal supercharger includes a housing 1, an impeller mounted therein, made in the form of a hollow sleeve 2 with radial nozzles 3 and 4 interconnected along the periphery by means of a separation chamber 5 placed in an annular channel 6 communicated by a bypass nozzle 7 s the cavity 8 of the sleeve 2, the combustion chamber 9 communicated with the separation chamber 5 by means of intake pipes 10 and hydraulic pipelines 11, and perforated tubes 12 located in the radial nozzles 3 and communicated with the ATM area. Annular Channel & made in the housing 1. The radial nozzles 4 through one are filled from the side of the sleeve 2. The air intake pipes 10 are placed in the filled nozzles 4, and the perforated tubes 12 are located in the unplugged nozzles 3. The outer surface 13 of each radial nozzle 3 and 4 has a pterygoid profile. In the annular channel 6, on the suction side of the air, there is an annular ridge 14, and on the discharge side, a ridge 14. On the discharge side, a partition 15 is formed to form a cavity 16 communicated with the annular channel 6 through the opening 17 and the atmosphere through the opening 18. In the fairing 19 A feed tube 20 with a socket 21 is connected, connected to a high pressure line (not shown) and is axially displaceable. Sleeve 2 comprises a fuel line 22 in communication with a combustion chamber 9. The supercharger also contains an inlet guide vane 23 installed in front of the radial nozzles 3, and a spraying apparatus 24 mounted behind the radial nozzles 3, the radial nozzles 3 and 4 being rotatable. The combustion chamber 9 contains an exhaust nozzle 25 installed in the displacement channel 26 in communication with the pipeline 11 and the separation chamber 5. An ignition plug 27 is installed in the combustion chamber 9. The centrifugal supercharger is working barely blowing. When the supercharger is started up, the feed tube 20 is moved to the right until the overflow pipe 7 is closed by the socket 21. Compressed air is fed into the cavity 8 through the feed tube 20, and the fuel line 9 into the combustion chamber 9 generates a pulse to rotate the impeller. When the engine speed is reached, the feed tube 20 is returned to its original position, the fluid enters the cavity 8 of the sleeve 7 and, under the action of centrifugal forces, connects the separation chamber 5 through the nozzles 3, drawing air from the atmosphere through the perforated tubes 12 into radial nozzles 3. In the separation chamber 5 under the action of centrifugal forces, the liquid separates from the air, while air enters through the radial nozzles 4 and the pipelines 10 into the combustion chamber 9, and the liquid the cut hydraulic pipe 11 enters the mixing channel 26, mixes with the jet stream of the combustion products of the combustion chamber 9 and enters the annular channel 6, from where the liquid flows through the overflow channels 7 into the cavity 8, and the gaseous combustion products through the cavity 16 and the holes 17 and 18 out into the atmosphere.

Due to the pterygoid shape of the radial nozzles 3 and 4, due to their rotation, a directed movement of air flow in the axial direction of the blower is created.

This embodiment of the centrifugal supercharger provides increased reliability due to the use of a combustion chamber installed on the impeller as the engine, in combination with centrifugal hydrocompression of the air entering the combustion chamber and recovery of the spent fluid.
