Abstract: The present invention relates to an abrasive blasting device characterized in that to the first longitudinal inlet end of the injection abrading diffuser 1 there is associated a socket 2 and to the second longitudinal inlet end of the diffuser there is associated a conduit 3. The free end of the conduit 3 is closed by a cage-like collector 4, the mantle wall thereof diverging in the direction towards the diffuser 1. In the area of connection with said bottom of the collector 4 the conduit 3 is formed with a set of radial recesses 5, the interiors of the socket 2 and the conduit 3 being mutually interconnected by means of a connection-injection pipe 6. The latter projects into the conduit 3 essentially through said bottom of the collector 4. On the outer surface of the wall of the socket 2 and in the area of its free end there is diametrally opposed arranged a pair of ribs 10 bearing a guide wheel unit 10' in each case.
