SEALING LIP FOR A LOW FRICTION BONDED PISTON SEAL

An annular seal for a low friction bonded piston seal is provided. The annular seal having a central axis and including an annular seal body symmetrically positioned about the central axis. The annular seal is integrally molded to the body and provides a lower seal lip body, and a top seal lip. The top seal lip including a first radial lip thickness T1 and a second radial lip thickness T2. A ratiobetween second radial lip thickness T2 to first radial lip thickness T1 is less than 1.00. The annular seal includes a radial lip height H, and a radial lip overall pressure received thickness T3. Aratio of radial lip height H to second radial lip thickness T2 is greater than or equal to 0.65. The radial lip overall pressure received thickness T3 is less than or equal to 0.8 mm. The first radiallip thickness T1 is less than or equal to 0.7 mm. 本发明提供了种用于低摩擦结合活塞密封件的环形密封件。该环形密封件具有中心轴线并且包括环形密封件主体，所述环形密封件主体绕着中心轴线对称地定位。环形密封唇与所述主体体成型并设置有下部密封唇主体和顶部密封唇。顶部密封唇包括第径向唇厚度(T1)和第二径向唇厚度(T2)。第二径向唇厚度(T2)与第径向唇厚度(T1)之间的比率小于1.00。环形密封件包括径向唇
