ABSTRACT:
Hydraulic apparatus including hydraulic supply means and an accumulator with an accumulator piston and a means for sensing the accumulator piston position to indicate a load requirement to a control means to selectively actuate the hydraulic supply means to satisfy the hydraulic load requirement and to provide a relatively pressure pulse-free operation by actuating the hydraulic supply means in response to the position and motion of the accumulator piston.
