摘要

The apparatus, in particular workshop - and / or hobby system, for the discontinuous process, in particular a vacuum suction beams, on surfaces, with a vacuum source (1), a container (2) for the accommodation of blasting material, a jet lance (4) arranged coaxially with respect to the acceleration tube with an injector (5), which consists of a nozzle body having a cross-sectional constriction (6) and coaxially to the hose line (10) for supplying the sand from the container to the site of treatment is formed, the hose line with a the blasting material feed tube (12) for sucking in of blasting material into the hose is provided, and a suction hose (22) for the removal of the blasting material from the jet lance to the vacuum source, characterized in that the nozzle body (6) a mixing tube (7) is arranged downstream of a somewhat in relation to the diameter d₃ the feed hose (10) of larger diameter d₂ having.
