    The invention relates to turbocompressor engineering.
    A device for cleaning a gas turbine of a turbocharger of an internal combustion engine
    A disadvantage of the known device is the contamination of nozzles in the periods between turbine cleanings.
    The purpose of the invention is the prevention of nozzle contamination.
    This goal is achieved by the fact that a compressed gas source is connected to the reservoir with a supply line, on which a two-way valve is installed, which has two inlet and two outlet pipes respectively connected with them, one of which is connected to the reservoir and the other to the pipeline.
    The device can be equipped with a programming unit for automatic control connected to the rear. '. h 5 In the supply line in front of the inlet pipe in communication with the outlet pipe connected to the pipeline, a throttle washer with a calibrated hole is installed.
    10 A non-return valve is installed on the pipeline between the tank and the connection point to the outlet pipe.
    The inlet pipes can be connected by means of a locking element to the intake manifold of the engine.
    The drawing schematically shows the proposed device.
    The device comprises a washing liquid reservoir 1 connected by a pipe 2 to nozzles 3 installed in front of the gas turbine of the engine compressor 4
    953992 4 of internal combustion with an intake manifold 5. A source 6 of compressed air is connected to the reservoir 1 with a supply line 7, on which a two-way valve 8 with a shut-off 5 element 9 ”is installed, having a supply pipe 10 in communication with a discharge pipe 11 connected via a 12 s line the space of the tank 1 above the washing liquid, ί0 and the inlet pipe 13, in communication with the outlet pipe 14, connected via line 15 to the pipe. wire 2. The device is equipped with a programming unit 16 of automatic * 5 control, for example, an hour meter connected to a gate valve 8. A throttle washer 17 with a calibrated hole is installed in the supply line in front of the inlet pipe 13. 20 Between reservoir 1 and location. g (for connecting to the pipeline 2 of the line 12, a check valve 18 is installed.
    The inlet pipes 10 and 13 can be connected to the intake manifold 5 of the internal combustion engine by means of a locking member 19 '.
    The device operates as follows.
    During the washing periods, the programming unit 16 supplies a signal to the gate valve 8, under the action of which the lock, the element 9 rises to the position shown in the drawing by the dash-dot line. In this case, compressed air from the source 6 through the supply line 7 through { nozzle 13, valve 8, nozzle 14 through line 15 enters the reservoir 1 and the flushing fluid through the check valve 18 enters the nozzles and carries out the turbine washing 4Q . In the periods between flushing, the locking element 9 is lowered, it covers the nozzles 13 and 14 and the air through the throttle washer 17, the nozzle 10, the valve 8, 4J, the nozzle 11 through line 12 enters the nozzles 3, ensuring their purging and thereby preventing pollution. In this case, the non-return valve 18 closes with air pressure, and the calibrated hole of the washer 17 obese · 50 prevents the supply of the minimum amount of compressed air necessary for blowing the nozzles. Air for boosting the reservoir 1 or for purging the nozzles 3 can be supplied from the intake manifold in which overpressure is created due to boosting.
