Abstract
A fluid activated valving apparatus for controlling a very high pressure liquid being adapted for serving as a focused jet liquid stream for use in cutting materials comprising an axially-aligned spindle located sealingly in a liquid delivery conduit adapted to introduce the high pressure liquid into a chamber. One or more bearings are disposed slidably about the free end of a spindle enclosed within the valve body, adapted for sealing engagement, and also to permit unstressed rotation of the spindle through a 360.degree. arc about the spindle longitudinal axis in response to torsional stresses being intermittently exerted on the exposed free end of the spindle.
