PETROLEUM HYDRAULIC FLUIDS

Abstract

HYDRAULIC ACTUATION of machinery has been performed for many years in a relatively modest way, but the increasing complexity of modern machinery has, of recent years, generated a greater appreciation of the virtues of this method of operation and control. The mechanical transmission of power by levers, cams and gears, might be regarded as the traditional method, but as greater demands were made for automatic operation and control, design complications became increasingly complex, and the principles of hydraulics, which had hitherto been employed only on simple presses, assumed much greater importance.
