Abstract : The present invention relates to a square wave fluid pressure generator which includes a rotor plate and a back plate which are mounted on a support element in a face-to-face relationship with respect to one another. The back plate has a central aperture which is aligned with the axis of rotation of the rotor plate and has additional apertures which are radially disposed from such axis of rotation. The rotor plate has a depression which extends from the central aperture to the radially disposed apertures in the back plate so that upon rotation of the rotor plate the depression communicates the central aperture alternately with the radially disposed apertures. When differential fluid pressures such as liquid pressures are applied between the radial apertures in the back plate the central aperture thereof provides a sqaure wave pressure output. (Author)
