Abstract
A piston pump includes a main body having an inlet, an outlet, and a chamber fluidly connected to form at least a portion of a first fluid flow path for receiving a flow of fluid therein. The pump also includes a second fluid flow path to provide fluid communication between the chamber and a point upstream of the inlet of the main body. A piston is disposed in the chamber of the main body and reciprocatingly moves therein to cause the flow of the fluid through at least one of the first fluid flow path and the second fluid flow path. An adjustment element is disposed in the main body and configured to adjust an effective flow of the fluid through the first fluid flow path.
