Abstract

A hydraulic powering system includes a hydraulic cylinder, an accumulator, and a manifold assembly. The hydraulic cylinder includes: (i) a hydraulic cylinder construction having a hydraulic cylinder wall and first and second hydraulic cylinder end caps forming an internal volume, a piston constructed to slide within the internal volume between the first and second hydraulic cylinder end caps and dividing the internal volume into an extend region and a retract region, and a piston rod extending from the piston and through the retract region and one of the first and second end caps to outside the hydraulic cylinder; (ii) an extend port in fluid connection with the extend region of the hydraulic cylinder; and (iii) a retract port in fluid communication with the retract region of the hydraulic cylinder. The accumulator includes: (i) an accumulator construction having an accumulator wall and first and second accumulator end caps forming an accumulator internal volume, an accumulator piston constructed to slide within the accumulator internal volume between the first and second accumulator end caps and dividing the accumulator internal volume into a hydraulic fluid region and a compressible gas region; and (ii) a hydraulic fluid port in fluid communication with the hydraulic fluid region of the accumulator. The manifold assembly includes a plurality of passageways therethrough providing fluid connection between: (i) a hydraulic fluid extend source and the hydraulic cylinder extend port and the accumulator hydraulic fluid port; and (ii) a hydraulic fluid retract source and the hydraulic cylinder retract port and the accumulator hydraulic fluid port. A method of operating a hydraulic powering system is described.
