Abstract
A mechanism for the treatment of materials by pressurized water jets includes a body ( ) for supplying water under pressure which includes a feeding chamber ( ) extending over the whole length of the body, and wherein water under pressure is fed to the feeding chamber through a filter ( ). The body also includes a distributing zone for distributing water under pressure over a whole treatment length against a plate ( ) provided with micro-perforations which define water needles ( ) directed against the surface (S) of the material to be treated. The material is supported by a carriage element subjected to a suction source eliminating the treatment water. Further, water transfer from the intake chamber ( ) to the perforated plate ( ), is done through a channel ( ) with a rectangular cross-section extending over the whole length of the injector, from the periphery of the feeding chamber ( ) up to the surface or the perforated plate ( ), wherein the spacing between the side walls ( ) of the channel and the height thereof produces a unidirectional and stable stream of water without turbulence.
