Abstract:
Device for the abrasive blasting of workpieces, having a chamber (2) with at least one closable opening (3), an extraction device connected to the chamber (2) in order to extract air therefrom, a container (8) for holding blasting agent, and having a blasting pipe unit (5), which can be introduced into the chamber (2) via said closable opening (3) and which has an inlet (12) for the blasting agent, which inlet is connected to a feed line (7), an inlet (13) for ambient air and an outlet opening (14) for the blasting agent, whereby whence blasting pipe unit (5) is introduced into the chamber (2) through the opening (3) in the chamber (2), the blasting agent is transferred from the blasting agent container (8) via the feed line (7), together with the ambient air which is sucked in via the air inlet (13), into the chamber (2), owing to the subatmospheric pressure generated in the chamber (2) when the air is extracted therefrom.
