Abstract:
A control valve, comprising;a valve housing including a valve cavity;an inlet means formed in said valve housing for directing fluid into said valve cavity;an outlet means formed in said valve housing for directing fluid out of said valve cavity;a valve element mounted for reciprocal movement in said valve cavity between open and closed positions, said valve element biased toward said closed position by fluid pressure forces;a valve seat associated with said valve element, said valve element engaging said valve seat when in said closed position and permitting flow between said valve seat and said valve element when in said open position; anda flow force inducing means positioned adjacent said valve element for redirecting fluid from said inlet means through a predetermined flow path arranged relative to said valve element to cause fluid flow to impact said valve element and create flow induced forces of sufficient magnitude necessary to advantageously counteract said fluid pressure forces, wherein said valve element includes a recess and said flow force inducing means includes a flow deflecting extension positioned on said valve housing which extends at least partially into said recess.
