    • A corrugation (130) has a radially inner wall (146) circumferentially surrounding an axis (113). The inner wall (146) defines an inner cavity (150) configured to conduct a liquid axially through the inner cavity (150). A radially outer wall (156) of the corrugation (130) overlies the inner wall (146). The outer wall (156) adjoins the inner wall (146) so as to form a closed outer cavity (160) bounded by the inner and outer walls (146,156) and separated from the inner cavity (150) by the inner wall (146). The inner wall (146) has at least one opening (162) providing fluid communication between the inner and outer cavities (150,160) for the corrugation (180) to serve as a reservoir for the liquid.
    • 波纹(130)具有沿周向围绕轴线(113)的径向内壁(146)。 内壁(146)限定内腔(150),该内腔构造成轴向地引导液体通过内腔(150)。 波纹(130)的径向外壁(156)覆盖内壁(146)。 外壁(156)邻接内壁(146)以形成由内壁(146,156)和由内壁(146)与内腔(150)隔开的封闭外腔(160) 。 内壁(146)具有至少一个开口(162),该开口提供用于波纹(180)的内腔和外腔(150,160)之间的流体连通以用作液体的储存器。

    • 波纹(130)具有周向围绕轴线(113)的径向内壁(146)。 内壁(146)限定了内腔(150),所述内腔(150)被构造成使液体轴向地穿过内腔(150)。 波纹(130)的径向外壁(156)覆盖在内壁(146)上。 外壁(156)邻接内壁(146),以形成由内外壁(146,156)限定并由内壁(146)与内腔(150)隔开的封闭外腔(160) 。 内壁(146)具有至少一个开口(162),其提供用于波纹(180)的内腔和外腔(150,160)之间的流体连通,以用作液体的储存器。
