The invention relates to a sealing member (1), in particular for sealing a piston (20). The sealing member (1) comprises a partial annular body (2) comprising a slit portion (3) and a body portion (4), where the partial annular body (2) extends annularly about a central axis (z) and a radial axis (r) is defined perpendicular to the central axis (z). Further, the body portion (4) includes a topmost surface (5) and a bottommost surface (6) as end faces with respect to the central axis (z). A thickness (7) between the topmost surface (5) and the bottommost surface (6) in an axial direction parallel to the central axis (z) of the body portion (4) varies along a circumferential direction (8) of the body portion (4). The invention also relates to a door actuator (100) comprising the sealing member (1).
本发明涉及一种特别地用于密封活塞(20)的密封构件(1)。密封构件(1)包括部分环形本体(2)，该部分环形本体(2)包括狭缝部分(3)和主体部分(4)，其中，部分环形本体(2)绕中心轴线(z)环形地延伸，并且径向轴线(r)定义成与中心轴线(z)垂直。此外，主体部分(4)包括作为相对于中心轴线(z)的端面的最顶部表面(5)和最底部表面(6)。在最顶部表面(5)与最底部表面(6)之间的沿与主体部分(4)的中心轴线(z)平行的轴向方向的厚度(7)沿着主体部分(4)的周向方向(8)变化。本发明还涉及一种包括密封构件(1)的门致动器(100)。
