Abstract
A pump includes a pump casing defining a first chamber and a second chamber, and fluid moves from the first chamber to the second chamber during a stroke. The pump also includes a needle that is movably disposed in the first chamber and a valve carriage that is movably disposed in the second chamber. The valve carriage includes an internal stop, and the valve carriage also includes a cavity therein that is partially defined by the internal stop. The pump further includes a valve that is movably disposed within the cavity of the valve carriage, and the valve is operable to be impacted by the needle during the stroke. Also, the needle is operable to impact the valve carriage during the stroke. Moreover, the valve is operable to impact the internal stop during the stroke at a time different from the needle impacting the valve carriage.
