摘要:
In a device for restoring a throttle valve, which is for controlling combustion air of an internal combustion engine, into a definite limp-home air position, having a throttle valve shaft, which supports a drivable driver and is rotatably supported in a housing, and having a prestressed clamping spring, whose spring ends, by simultaneously embracing a housing catch and a driver catch on opposing catch surfaces, fix a limp-home air position of the throttle valve, from which the throttle valve can be moved through rotation of the driver , a compensation spring, which has a definite initial stress force directed counter to the spring force of the clamping spring, is disposed between one spring end of the clamping spring and a catch surface on one of the catches in order to produce a rotary play-free state of the driver in the limp-home air position.
