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 at least one axially aligned and opposed high pressure cylinder. each high pressure piston being connected to the aligned low pressure 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 cylinders. |
