Abstract
A flow-diverter assembly includes a housing having a discharge port, a valve piston located in the housing, and a barrel cam coupled to the valve piston. The valve piston includes a valve body in fluid communication with an internal flow passage of the housing, and is movable axially along a longitudinal axis of the housing between an open position, where a vent of the valve body is fluidly coupled to the discharge port, and a closed position, where the vent of the valve body is substantially sealed from the discharge port.
