Abstract
An inlet baffle chamber () is provided in the port cover () of a piston pump. The inlet baffle chamber () fluidly connects a compressed piston chamber to an adjacent lower pressure piston chamber while the lower pressure piston chamber is in the suction cycle and separately receiving fluid from an inlet manifold () of the port cover (). Instead of de-compressing high pressure fluid directly to pump's inlet () as in prior art pumps, the inlet baffle chamber () directs fluid to the next piston that is already in the suction cycle.
