Abstract: An accumulator piston for an automatic transmission. The piston comprises two components, the first and second being cup elements welded together with their closed ends in abutting relation. The lower cup includes a curled back portion with a radial flange having an axially extending bi-directional oil seal thereon, and spaced apart recesses in the curled back portion to permit oil to flow therein. The upper cup includes a radial flange of reduced diameter compared to the lower cup flange. The flange also has a lip seal thereon. The piston is spring-loaded and moves up and down in a bore and counterbore in response to fluid flow on either side of the piston to absorb shifting shocks.
Abstract translation: 用于自动变速箱的蓄能器活塞。 活塞包括两个部件，第一和第二杯杯元件以其邻接关系的封闭端焊接在一起。 下杯包括卷曲后部，其具有径向凸缘，其上具有轴向延伸的双向油封，并且在卷曲的后部中具有间隔开的凹部，以允许油在其中流动。 上杯与下杯法兰相比，包括径向法兰缩径。 凸缘也在其上具有唇形密封。 活塞是弹簧加载的，响应于活塞两侧的流体流动而在孔和沉孔中上下移动以吸收移动冲击。

Abstract: A tone ring assembly for use on a rotatable machine part. The tone ring is able to generate a varying voltage output when rotated at varying speeds. A fixed position magnetic sensor detects this voltage. The tone ring comprises an axially extending main body portion having a plurality of areas able to generate a voltage upon rotation. A retainer having at least one radial flange prevents axial movement of the tone ring and the tone ring includes ribs and spaces on its inside diameter to permit oil to pass therethrough.

Abstract: An oil seal having the usual lips for retaining oil and a guide member made of a variety of relatively stiff or rigid materials. The guide member is made slightly larger than the smallest diameter of the seal member when the seal rests on the shaft. The seal member can have the guide member on either the air side or the oil side of the seal. The disclosure also relates to a shipping plug, which is inserted into the seal and retains the oil in place during shipping when the seal is installed but a shaft is not installed.
Abstract translation: 具有用于保持油的通常唇缘的油封和由各种相对刚性或刚性材料制成的引导构件。 当密封件位于轴上时，引导构件略大于密封构件的最小直径。 密封构件可以在密封件的空气侧或油面上具有引导构件。 本公开还涉及一种运输塞子，其在密封件安装但没有安装轴时，在运输期间插入密封件中并将油保持在适当位置。

Abstract: A controllable magnetorheological fluid valve for controlling magnetorheological fluid. The controllable fluid valve includes a magnetorheological fluid conduit with a magnetorheological fluid path. The controllable fluid valve includes a north magnetic pole and a south magnetic pole, with the south magnetic pole proximate the north magnetic pole with a magnetic discontinuity spacer between the south magnetic pole and the north magnetic pole wherein the spacer forces nontraversing magnetic flux lines from said north pole out into the magnetorheological fluid path and then back into the south pole.
Abstract translation: 一种用于控制磁流变流体的可控磁流变流体阀。 可控流体阀包括具有磁流变流体路径的磁流变流体导管。 可控流体阀包括北磁极和南磁极，南磁极靠近北磁极，在南磁极和北磁极之间具有磁性不连续的间隔物，其中间隔件迫使来自所述的磁极的非磁性磁通线 北极进入磁流变路径，然后回到南极。
