Abstract
Flow enhancing restrictors are located within a fluid conduit to provide pressure reduction and flow enhancement. The restrictors may be used in combination with a conventional choke valve or as a stand-alone pressure reduction means. Alternative exemplary embodiments for flow enhancers are described. Each of the flow enhancers has a generally cylindrical base with at least one fluid passage disposed therethrough. Each of the flow enhancers also provides a dome that projects upwardly from the center of the base to assist in directing fluid flow and receiving the abrasive forces associated with the fluid.
