Definitions
- the resetting device also includes a clamp spring 18, which is designed here as a helical torsion spring with spring legs 181, 182 bent at the spring ends.
- the clamp spring 18 is arranged coaxially with the driver 12, with its spring legs 181, 182 extending transversely to the axis 17 of the driver 12 or the throttle valve shaft 11.
- the clamp spring 18 clasps with its spring legs 181, 182 the fixed cam 13 and the driver cam 14 with pretension and fixes the basic position of the reset device, from which the throttle valve shaft 11 with throttle valve 10 can be rotated by tightening the clamp spring 18 by rotating the driver 12 in one or the other direction of rotation.
- each spring leg 181 or 182 overlaps a stop surface 131 or 132 on the fixed cam 13 and a stop surface 141 or 142 on the driver cam 14.
- the stop 12 becomes Spring legs 181 or 182 are carried along by the stop surface 141 or 142 of the driving cam 14, while the other spring leg 182 or 181 is supported on the stop surface 132 or 131 of the fixed cam 13.
- the elastic spring element is formed by a spring tongue 19 bent in one piece at the leg end of the spring leg 181.
- the spring tongue 19 is formed by the free stirrup leg of a U-shaped spring clip 20 bent at the end of the leg and oriented in the direction of rotation of the driving cam 14, the other stirrup leg 21 of which is integral with the spring leg 181 on that of the stop surface 141 opposite side of the spring tongue 19 extends over the axial height of the helical torsion spring.
- the driver cam 14 is preferably carried out with a width seen in the direction of rotation of the driver cam 14, which is smaller than the width of the taking into account maximum allowable manufacturing tolerances
- both spring legs 181 and 182 always rest on all four stop surfaces 131, 132, 141, 142, the spring leg 181 being in contact with the stop surface 141 of the driving cam 14 by the spring tongue 19.
- the spring leg 182 can of course also be provided with the spring tongue 19 described, which then presses against the stop surface 142 of the driving cam 14.
- a further exemplary embodiment of the resetting device is outlined, only the clamp spring 18, again designed as a helical torsion spring, as well as fixed cams 13 and driver cams 14 being shown.
- the clamp spring 18 again designed as a helical torsion spring, as well as fixed cams 13 and driver cams 14 being shown.
- an elastic spring element is present, which is supported with a spring force that is less than the biasing force of the clamp spring 18 in the basic position of the rotary member, on the stop surface assigned to the leg portion.
- This resilient effect of the two spring legs 181, 182 can be achieved not only by reducing the cross section, but also by designing the length of the spring legs 181, 182 accordingly.
- the bearing surface 131, 132 and 141, 142 of the cams 13, 14 are radially so far apart from one another that the spring legs 181, 182 can spring at this distance. If a large rotational play between the cams 13, 14 has to be compensated, it is advantageous to design the spring legs 181, 182 both relatively long and with a reduced spring wire cross section.
- the spring legs 181, 182 are as in the exemplary embodiment of the resetting device according to FIG. 4 and 5, that is to say relatively long and with a wire cross section that is reduced compared to the cross section of the spring wire 18.
- the spring leg 181 is elastic at its end of the leg
- Spring element in the form of a spring tongue 19 ′ bent in one piece from the spring leg 181, which rests under prestress on the stop surface 141 of the driving cam 14.
- This spring tongue 19 ' is formed in the same way as described in the embodiment of FIGS. 1-3 by the free arm leg of a spring arm 20' bent at the leg end.
