    • A radial shaft seal is provided for sealing between high and low pressure sides in an annular space between a shaft and a static structural receiving part, wherein the shaft seal is rotationally symmetric and arranged coaxially to the shaft. A first sealing ring has an inner periphery bulging toward the low pressure side and forms a first sealing lip abutting the shaft. A spacer ring has first and second faces directed towards the high and low pressure sides, respectively. An elastic shaped part has an outer periphery abutting the second face of the spacer ring and an inner periphery bulging toward the high pressure side and abutting the first sealing lip. At least the spacer ring and elastic shaped part define a cavity subjected to the high pressure side or a control pressure which presses the first sealing lip against the shaft via the elastic shaped part.
    • 提供径向轴密封件,用于在轴和静态结构接收部分之间的环形空间中的高压侧和低压侧之间进行密封,其中所述轴密封件是旋转对称的并且与所述轴同轴布置。 第一密封环具有朝向低压侧凸出的内周边并且形成邻接轴的第一密封唇。 间隔环分别具有朝向高压侧和低压侧的第一和第二面。 弹性成型部具有与隔离环的第二面邻接的外周和向高压侧突出的内周,并抵靠第一密封唇。 至少隔离环和弹性形状部分限定经受高压侧的空腔或通过弹性成形部将第一密封唇压靠在轴上的控制压力。
