Blasting pipe for a high-pressure cleaning device

摘要

In order to achieve a simplified construction in a blasting pipe for a high-pressure cleaning device having two pieces of pipe arranged concentrically relative to one another and leading in each case to their own outlet opening, and having a switch-over device which connects a feedline for liquid cleaning medium selectively only to the inner piece of pipe or to both pieces of pipe, it is proposed that the switch-over device displaces the blasting pipe and the feedline in an axial direction relative to one another between two positions, the feedline adjoining the inner piece of the blasting pipe in a sealing manner in the nearer position whereas, in the pulled-apart position between itself and the inner blasting pipe, it exposes an opening leading into the outer piece of the blasting pipe.
