The invention relates to a control device comprising a mechanical seal (24) that guides the rotation of a control rod (22) relative to a frame (20) about two pivot connections having orthogonal axes. The mechanical seal (24) comprises, for at least one of the pivot connections, return means (54) for returning the movable part (52) to a neutral position relative to the fixed part (50), the return means (54) comprising at least one resilient member (70) comprising two branches (72, 76), the two branches (72, 76) being arranged in the fixed part (50). Each branch extends from a finger (60) integral with one of the movable part (52) and the fixed part (50) in a manner orthogonal to the axis (X) of the pivot connection up to each free end (74, 78). The or each elastic member (70) is capable of preventing the free ends (74, 78) from moving towards each other. The elastic member (70) is inserted between a fixed pin (62, 64) integral with the fixed part (50) and a movable pin (66, 68) integral with the movable part (52) in a transverse direction (T) orthogonal to a bisector (B) of an angle between the branches (72, 76).
本发明涉及一种控制装置,该控制装置包括机械密封件(24),该机械密封件引导控制杆(22)相对于框架(20)围绕具有正交轴线的两个枢转连接件旋转。对于枢转连接件中的至少一个枢转连接件,该机械密封件(24)包括返回装置(54),该返回装置用于使可动部件(52)相对于固定部件(50)返回到中立位置,该返回装置(54)包括至少一个弹性构件(70),至少一个弹性构件包括两个分支(72,76),每个分支从与可动部件(52)和固定部件(50)中的一个成一体的指状件(60)以正交于枢转连接件的轴线(X)的方式延伸直到每个自由端部(74,78)。该弹性构件或每个弹性构件(70)能够防止自由端部(74,78)朝向彼此移动。该弹性构件(70)沿如下的横向方向(T)插入与固定部件(50)成一体的固定销(62,64)和与可动部件(52)成一体的可移动销(66,68)之间,该横向方向与分支(72,76)之间的角度的平分线(B)正交。
