In Figure 12 and Figure 18, executive component 5 is in the first bit-type, wherein, also can be clear that in the view of Figure 12, and executive component 5 is for Weight-optimised former thereby have a recess 27.

In the first bit-type, the executive component 5 of Figure 21 and Figure 22 is arranged among the directed executive component guider 8d, so that upside 29 is towards spring element 6 like this.Contact section 13 on the upside 29 and spring element 6 in other words pressure area section surface 21 contact in the first contact position 26, wherein, in other words its free end 12 of spring element 6 have been shown in primary importance 19 in Figure 12.

Correspondingly, measure abreast moderate distance between the first contact position 26a and the anchor portion 25 with respect to longitudinal direction 14.Described distance is corresponding to lever arm, and based on the length of described lever arm, free end 12 experiences a medium stroke between primary importance 19 and the second place 20.Correspondingly also be by lever arm and the formed medium sized torque of power of transmitting by executive component 5.Otherwise, the medium minimum force that is produced by springing dish 2 in principle be enough to make spring element 6 in other words its free end 12 be transitioned into relatively Figure 18 of second place 20(from primary importance 19).According to the medium stroke of free end 12, longitudinal direction 14 and thickness direction 16 rotate between primary importance 19 and the second place 20.

In the first bit-type of executive component 5, downside 30 is towards springing dish 2.Contact section 13 on the downside 30 is observed spaced apart with respect to the contact section 13 on the upside 29 at longitudinal direction 14.Observe at longitudinal direction 14, the contact section 13 on the downside 30 is arranged on contacting after the section 13 on the upside 29 in the first bit-type of Figure 12 and Figure 18.In other words, the distance of measuring at longitudinal direction 14 between the contact section 13 on the upside 29 and the anchor portion 25 is less than the distance in longitudinal direction 14 measurements between section 13 and the anchor portion 25 of contacting on the downside 30.

In Figure 13 and Figure 19, executive component 5 is in the second bit-type.With respect to the first bit-type of Figure 12 and Figure 18, executive component 5 is around rotating 180 ° with the axis of longitudinal axis 18 quadratures in other words with guidance axis 3d quadrature.Correspondingly, now, upside 29 towards springing dish 2 and downside 30 towards spring element 6.Consequently, now, the contact section 13 on the downside 30 and spring element 6 in other words pressure area section surface 21 contact in the second contact position 26b, wherein, in other words its free end 12 of spring element 6 have been shown in primary importance 19 in Figure 13.At this, the distance of measuring abreast with respect to longitudinal direction 14 between the second contact position 26b and the anchor portion 25 is greater than the situation shown in Figure 12.Therefore, corresponding lever arm is larger.Therefore, free end 12 is the less stroke of experience between the primary importance 19 of spring element 6 and the second place 20, relatively Figure 19.In the situation that the power that passes to movable section 11 by executive component 5 is applied in the same manner, synthetic torque is correspondingly greater than the situation shown in Figure 12.Otherwise, in the identical situation of the spring constant of spring element 6, treat in principle by the less minimum force that springing dish 2 applies be enough to make spring element 6 in other words its free end 12 be transitioned into relatively Figure 19 of second place 20(from primary importance 19).According to the less stroke of free end 12, longitudinal direction 14 and thickness direction 16 rotate between primary importance 19 and the second place 20.

In Figure 14 and Figure 20, executive component 5 is in the 3rd bit-type.With respect to the second bit-type of Figure 13 and Figure 19, executive component 5 rotates 180 ° around its longitudinal axis 18 in other words around guidance axis 3d.In other words, downside 30 is again towards spring element 6, and spring element 6 in other words pressure area section surface 21 is contacted in the 3rd contact position 26c by the contact section 13 on the downside 30, wherein, in other words its free end 12 of spring element 6 has been shown in primary importance 19 in Figure 14.But the change of distance in longitudinal direction 14 measurements between the contact section 13 that now contacts with spring element 6 and the anchor portion 25 of spring element 6.Described distance is shorter than the distance in longitudinal direction 14 measurements between the first bit-type and short-and-medium in other words the 3rd contact position 26c of the second bit-type and the anchor portion 25.Therefore, corresponding lever arm is less.Therefore, free end 12 is the larger stroke of experience between the primary importance 19 of spring element 6 and the second place 20, relatively Figure 20.In the situation that the power that passes to movable section 11 by executive component 5 is applied in the same manner, synthetic torque is correspondingly less than the situation shown in Figure 12.Otherwise, in the identical situation of the spring constant of spring element 6, need in principle to treat by the larger minimum force that springing dish 2 applies make spring element 6 in other words its free end 12 be transitioned into relatively Figure 20 of second place 20(from primary importance 19).According to the larger stroke of free end 12, longitudinal direction 14 and thickness direction 16 rotate between primary importance 19 and the second place 20.

It should be noted that at last self-evidently, also can consider to have guidance system that the executive component guider 8d by a plurality of orientations forms and the embodiment of corresponding executive component 5, in order to can cover especially subtly especially on a large scale torque.
