Abstract: A vacuum pump comprises two stator components and a seal located between the components to provide a fluid-tight seal between the components. The seal comprises an annular plastics tube housing an annular reinforcing member, the tube being at least partially surrounded by a sleeve formed from one of FKM elastomer and FFKM elastomer.
Abstract translation: 真空泵包括两个定子部件和位于部件之间的密封件，以在部件之间提供流体密封的密封。 密封件包括容纳环形加强构件的环形塑料管，该管至少部分地被由FKM弹性体和FFKM弹性体之一形成的套筒包围。
