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.

Diffuser and flow control system with diffuser

A system and method allows the operation of a remotely located tool in an application where there is a telescoping space out joint in such a manner that the hanger need not be released. A hydraulic piston is surface actuated to move gripping teeth against the pipe and then take the pipe with the gripping teeth so that a tool that is engaged by the string can be remotely operated while safety features for the well can remain operative. The shifted position is held with maintained control line pressure. Some release of the control line pressure will not allow the operating piston to return. Rather, a check valve holds the shifted piston position until a differential pressure on the check valve drops to a predetermined value so that the check valve acts as a dump valve. The system operates off annulus pressure if the control line is damaged.
