    • The inventive operating lever (10) is provided with a screw/nut assembly (12) which comprises a fixed element (14) interacting with a movable element (16) by screwing. Said mobile element (16) is provided with a seating element (18) interacting with a diaphragm (20) and consists of two parts in the form of assisting (22) and supporting (24) parts, respectively which are movable with respect to each other. In addition, said operating lever (10) comprises assisting means (26) for displacing the seating element (18) which are used for cinematically connecting the assisting part (22) of the movable element (16) to a drive element which is rotationally connected to the diaphragm (20) or formed thereby. In the preferred embodiment, the seating element (18) comprises a bearing (28) which is provided with two rings, i.e. a rotatable ring (28b) interacting with the diaphragm (20) and a rotationally fixed ring (28a) carried by the part of the support (24) of the movable element (16). The assisting part (22) of the movable element (16) interacts with the rotatable ring (28b) by means of complementary friction (30).
    • 本发明的操作杆(10)设置有螺钉/螺母组件(12),其包括通过旋拧与可移动元件(16)相互作用的固定元件(14)。 所述移动元件(16)设置有与隔膜(20)相互作用的座位元件(18),并且分别由辅助(22)和支撑(24)形式的两个部件组成,所述两个部件可相对于每个部件移动 其他。 另外,所述操作杆(10)包括辅助装置(26),用于移动所述座椅元件(18),所述座椅元件用于将可移动元件(16)的辅助部件(22)电动连接到驱动元件,所述驱动元件被旋转地连接 (20)或由此形成。 在优选实施例中,座位元件(18)包括一个轴承(28),该轴承设置有两个环,即与隔膜(20)相互作用的可旋转环(28b)和由该部分承载的旋转固定环(28a) 的可移动元件(16)的支撑件(24)。 可移动元件(16)的辅助部件(22)通过互补摩擦(30)与可旋转环(28b)相互作用。
