ABSTRACT:
A control apparatus for a sand blasting nozzle is shown having means to induce a suction in the sand delivery conduit associated with the nozzle. A sliding valve structure for controlling the induced vacuum in the sand delivery conduit is provided along with a valve for controlling flow of the fluid medium for impelling the sand. The system makes use of high velocity air or steam or high pressure water or similar fluid for inducing the required suction in the sand delivery line and for driving the sand against the object to be blasted. Handle means form part of the apparatus to control the direction of the stream of abrasive and carrier fluid blasted from the nozzle portion of the assembly.
