    摘要: An active retractable seal assembly for use between rotating and non-rotating turbo machinery components including: a plurality of seal rings mounted to the non-rotating component, the seal rings movable toward and away from the rotating component between respective closed and open positions as a function of pressure drop across the seal rings, wherein the seal rings are normally in the open position; and a fluid bypass circuit for directing fluid around one or more of the plurality of seal rings to reduce the pressure drop across the one or more of the seal rings, thereby causing the one or more seal rings to move towards the open position under the action of spring(s) or actuator(s).

    摘要: A shaft seal reduces leakage between a rotating shaft and a stator. The shaft seal includes a plurality of plate members attached to the stator in facing relation. The plate members define a sealing ring between the stator shell and the rotating shaft. A thickness of the plate members tapers from thick to thin from a stator end to a rotating shaft end. In this manner, with the more tightly packed tips of the plate members, axial leakage is reduced by tapering the plate members so that the plate roots are thicker than the plate tips.

    摘要: Flexure bearing systems and configurations guide translational motion along a single-axis in micro and macro applications such as micro-electro-mechanical system (MEMS) devices including sensors and actuators like electrostatic comb-drive actuators. The flexure bearing systems and configurations described herein provide an improved constraint against movement (i.e., stiffness) of the primary mover in non-motion axes such as a bearing axis.

    摘要: A multiple degrees of freedom motion system comprising an arrangement of rigid stages, flexure constraint modules, actuators, and sensors. These components of the motion system are arranged and connected in a systematic fashion to provide a high degree of decoupling between the motion axes, suitable placement of ground-mounted actuators to actuate each motion axis, and suitable placement of sensors to allow end-point measurement along each motion axis. This arrangement of rigid stages, flexure constraint modules, actuators and sensors enables large motion range and high motion quality in the motion system, while using standard and commonly available components.

    摘要: A shaft seal assembly between a rotating shaft and a static shell is disclosed. The shaft seal assembly includes a seal housing in mechanical contact with the static shell, at least two rigid members of the seal housing, and a plurality of compliant plate members defining a sealing ring between the static shell and the rotating shaft. The plurality of compliant plate members is disposed between the at least two rigid members and retained within the seal housing by a compressive force between the at least two rigid members.
