Device for abrasive liquid suspension blasting

摘要

The jet-forming device has a high pressure pump feeding a main line (2) and a parallel secondary line (4) closable by a check valve (12) through a pressure reservoir (6) for the suspension leading back to the main line ending in a nozzle. The secondary line contains a valve (8) controlling the feed to the main line, which is also fed through the valve so that the valve body (2) is flushed out by the main-line liquid.
