Abstract (en)
1. Pressure chamber abrasive blasting device, comprising a blasting medium container (1) provided with a blasting medium filler aperture (3) which is sealable by means of sealing cone (2), and comprising a blasting nozzle connected to the blasting medium container (1) by means of blasting hose (4), wherein the blasting medium container (1) and the blasting hose (4) are connected to a source of compressed air through the intermediary of a pressure medium control valve (5), and the sealing cone (2) extends into the pressure medium supply line (6), which extends into the container (1), in such a manner that said cone is actuated into its sealing direction by the inflowing pressure medium, characterised in that a two-/three-way valve is provided as the pressure medium control valve (5) and is pneumatically actuable by an additional two-/three way valve serving as sensor (7), and the pressure medium control valve (5) controls a pressure medium line which forms branches to the blasting medium container (1) and to the blasting hose (4), wherein a water separator (9) is disposed between the pressure medium control valve (5) and the container (1) upstream of the branching junction (10), and a non-return valve (12) is disposed in the branch (8) extending to the blasting hose (4).
