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.

摘要翻译： 一种流量控制系统，包括具有一个或多个端口的心轴; 与心轴密封接触的一个或多个密封件; 围绕心轴定位的壳体和一个或多个密封件并与一个或多个密封件密封接触。 一个或多个扩散器放置在流量控制系统的流体通路中。 一个或多个扩散器包括具有支承表面的内圈; 具有支承面的外圈; 与内座圈和外座圈接触的轴向取向楔块，并且构造成增加内座圈承载面之间的距离。 具有楔形件的外滚道轴承表面在一个方向上移动，同时允许内滚道轴承表面和外座圈支承表面之间的距离随楔形件沿相反方向移动而减小。 与内座圈和外座圈接触的第二轴向取向楔块，其构造成在一个方向上楔形运动时增加内座圈承载面与外座圈承载面之间的距离，同时允许内座圈承载面和 外圈轴承表面随着相反方向的楔块运动而减小。
