Abstract

A reciprocating fluid pump may include a pump body, one or more subject fluid chambers within the pump body, one or more drive fluid chambers within the pump body, and a shuttle valve for shifting flow of pressurized drive fluid between two or more conduits. The shuttle valve includes a valve body and a spool disposed within the valve body and configured to move between a first position and a second position within the valve body. The shuttle valve also includes one or more magnets carried by the spool. The magnets are located and configured to impart a force on the spool responsive to a magnetic field such that the spool is magnetically biased away from an intermediate position between the first position and the second position.
