Summary:A linearly actuated hydraulic piston pump is provided. The pump includes a piston disposed between a first section and a second section of a piston chamber. The pump also includes a control valve having a valve body defining a valve chamber therein. The control valve also includes an inlet port, a first port, a regeneration port, a second port, and a spool. The spool in a first spool position fluidly couples a pressurized fluid source to the first section via the inlet port and the first port, and fluidly couples an accumulator to the second section via the regeneration port and the second port. The spool in the second spool position fluidly couples the first section to a drain via the first port and a drain port, and fluidly couples the second section to the pressurized fluid source via the inlet port and the second port.
