Abstract
A flow control including an annular flexible member and an internal post disposed downstream of the flexible member is described. The annular flexible member has a deflectable inner edge that defines a passage channel and the annular flexible member and internal post define a control gap therebetween wherein the deflectable inner edge of the annular flexible member deflects axially under increasing fluid pressure to reduce the control gap and consequently control fluid flow.
