Abstract
A fluid pressure amplifier is provided, which includes a pipe for flowing fluid and having an array of holes formed therein through which fluid can flow from within the pipe in use, and resiliently-movable obturator means adjacent the pipe and operatively responsive to fluid inlet pressure in the pipe, in which fluid inlet pressure causes the obturator means to oscillate between conditions which alternately permit and prevent fluid from passing through the holes, whereby the fluid leaving the pipe has a pulsed increased pressure. The amplifier is intended for use especially to increase the pressure of water flowing through a pipe submerged in a river, to provide a pumping action to a higher level.
Claims4
A fluid pressure amplifier comprising a pipe for flowing fluid, a chamber formed around the pipe and having an annular fluid outlet surrounding the pipe, the pipe having an array of holes formed therein through which fluid can flow from within the pipe into the chamber in use, and an obturator ring surrounding the pipe which is resiliently movable in the chamber and operatively responsive to fluid inlet pressure in the pipe such that fluid inlet pressure causes the obturator ring to oscillate between conditions which alternately permit and prevent fluid from passing through the fluid outlet thereby causing a pulsed pressure increase in fluid flowing through the pipe.
