ABSTRACT:
A fluid system is disclosed as having a variable displacement fluid pump connected in a closed-loop circuit to a multi-pressure chamber fluid cylinder. The effective pressure responsive areas of two of the pressure chambers are equal such that when fluid at a selected rate of flow and at a predetermined pressure is communicated to one of the chambers, a force of a predetermined magnitude is generated to cause contraction of the fluid cylinder at a predetermined rate. Similarly, when fluid at the same rate and flow is communicated to the other pressure chamber, a force of the same predetermined magnitude is generated to expand the fluid cylinder. A directional control valve is disposed in the closed circuit between the inlet and outlet of the fluid pump so as to selectively direct fluid to either of the pressure chambers to selectively expand or contract the fluid cylinder. The fluid system further comprises an accumulator and a second directional control valve means that is adapted to communicate a third pressure chamber of the fluid cylinder to the accumulator. The accumulator functions to maintain the pressure in the third fluid chamber to exert a force on the fluid cylinder balancing a selected load that the cylinder may be carrying during the expansion and contraction stages of the cylinder.
