DIFFUSER AND FLOW CONTROL SYSTEM WITH DIFFUSER

摘要

A flow control system including a mandrel having one or more ports; one or more seals in sealing contact with the mandrel; a housing positioned about the mandrel and one or more seals and in sealing contact with the one or more seals. One or more diffusers placed in a fluid pathway of the flow control system. The one or more diffusers including an inner race having a bearing surface; an outer race having a bearing surface; an axially oriented wedge in contact with both the inner race and the outer race and configured to increase distance between the inner race bearing surface. The outer race bearing surface with wedge movement in one direction while permitting distance between the inner race bearing surface and the outer race bearing surface to decrease with wedge movement in an opposite direction. A second axially oriented wedge in contact with both the inner race and the outer race and configured to increase distance between the inner race bearing surface and the outer race bearing surface with wedge movement in one direction while permitting distance between the inner race bearing surface and the outer race bearing surface to decrease with wedge movement in an opposite direction.
