Abstract

A method of controlling a piston pump is disclosed. The method includes actuating a plurality of pistons housed within a cylinder barrel to cause each of the plurality of pistons to engage in reciprocating motion. Fluid supplied to each of the pistons may be regulated by changing a clock position of an intake cam ring to cause a plurality of intake valves to open and close relative to the clock position of the intake cam ring. Fluid discharged by each of the pistons may be regulated by changing a clock position of an exhaust cam ring to cause a plurality of exhaust valves to open and close relative the clock position of the exhaust cam ring.
