Abstract
An apparatus that includes a housing with an input port and a first output port. A piston is disposed within a bore of the housing and includes a bypass via disposed transversely within the bore and a bypass tube disposed longitudinally within the bore. The bypass tube is configured to provide a flow path from the bypass via to a second output port on the bypass tube. The piston includes a sleeve disposed concentrically around the bypass tube. An interior chamber is defined by an exterior surface of the sleeve and an interior surface of the bore of the housing. The piston is configurable between a first configuration that provides a first flow path between the input port and the first output port via the interior chamber and a second configuration that provides a second flow path between the input port and the second output port via the bypass tube.
