Abstract

A pressure intensifier for a fluid comprises at least three piston assemblies disposed along mutually parallel axes equiangularly disposed with respect to a central axis of the intensifier and radially equidistant therefrom. Each piston assembly comprises at least one low pressure cylinder and a pair of axially aligned and opposed high pressure cylinders, each high pressure piston being connected to the low pres­ sure piston for conjoint axial movement therewith. Fluid is supplied to the low pressure cylinders from a supply means and discharged to a discharge means through a low pressure valve means operatively coupled to the pistons of each assembly so as to be driven thereby. High pressure collector means, usefully in the form of a closed circuit, are provided for receiving high pressure fluid from the high pressure cylin­ ders.
