Claim 10:
11. A method of operating a hydraulic powering system, the method comprising:
(a) feeding hydraulic fluid from an accumulator to a hydraulic cylinder side during a stroke of the hydraulic cylinder, wherein hydraulic powering system comprises:
(i) the hydraulic cylinder comprising:
(A) a hydraulic cylinder construction having a hydraulic cylinder wall and first and second hydraulic cylinder end caps forming an internal volume, a hydraulic cylinder piston constructed to slide within the internal volume between the first and second hydraulic cylinder end caps and dividing the internal volume into a first region and a second region, and a piston rod extending from the hydraulic cylinder piston and through one of the first and second end caps to outside the hydraulic cylinder;
(B) a first region port in fluid connection with the first region of the hydraulic cylinder; and
(C) a second region port in fluid communication with the second region of the hydraulic cylinder;

(ii) the accumulator comprising:
(A) 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;
(B) a hydraulic fluid port in fluid communication with the hydraulic fluid region of the accumulator; and

(iii) a manifold assembly comprising:
(A) a plurality of passageways therethrough providing fluid connection between the hydraulic cylinder second region port and the accumulator hydraulic fluid port; and

(B) a valve arrangement configured to direct flow of the hydraulic fluid through the manifold assembly, wherein the valve arrangement is configured to direct the hydraulic fluid in the hydraulic fluid region of the accumulator toward the second region of the hydraulic cylinder to accelerate movement of the hydraulic cylinder piston at a beginning of a stroke of the hydraulic cylinder.
