    • A lip seal having an annular body, a contiguous annular shoulder extending axially therefrom, and a contiguous annular seal lip extending coaxially from the body and flaring away from the shoulder. Strengthening ribs extend axially along the shoulder, the shoulder is undercut to provide space into which areas of the annular seal lip can escape, with each such feature thereby promoting nonuniform deformation of the annular seal lip, ensuring a path for fluid to flow, and thereby minimizing the possibility of a seal lock-up condition occurring when pressure is applied to the back of the lip seal during brake release. Flow ribs axially coextensive with the strengthening ribs also extend along the body to create fluid flow paths therebetween. The radial dimensions of the lip seal are also reduced to allow a valve cartridge of given diameter to function in a smaller housing bore than that required when a conventional lip seal is used, thus facilitating the downsizing of a control valve module in which the valve cartridge is to be used.
    • 唇形密封件具有环形体,从其延伸的邻接的环形肩部,以及从身体同轴延伸并从肩部向外延伸的邻接的环形密封唇。 加强肋沿着肩部轴向延伸,肩部被底切以提供空间,环形密封唇缘的哪个区域可以逃离,其中每个这样的特征从而促进环形密封唇的不均匀变形,确保流体流动的路径 最小化在制动器释放期间当唇部密封件的背面施加压力时发生密封锁定状态的可能性。 与加强肋轴向共同延伸的流肋也沿着主体延伸以在它们之间产生流体流动路径。 唇形密封件的径向尺寸也减小,以允许具有给定直径的阀芯在比使用常规唇形密封件时所需的更小的壳体孔中起作用,因此有助于减小控制阀模块的尺寸,其中阀芯 将被使用。
