| 摘要 |
The present invention is a micro-abrasive blasting device (55) with superior perturbation control via a plurality of delivery conduits (25) of various lengths and apertures. The user is able to individually open and close bypass conduit pinch valve (99) external to micro-abrasive blasting device (55) to affect the perturbation intensity internal to the mixing chamber (23). By selectively opening and closing flow through delivery conduits (25) it is possible to provide a more consistent perturbation rate and select the perturbation intensity internal to mixing chamber (23).
