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 (11), which supports a drivable driver (12) and is rotatably supported in a housing (10), and having a prestressed clamping spring (13), whose spring ends (131, 132), by simultaneously embracing a housing catch (14) and a driver catch (15) on opposing catch surfaces (16, 17), fix a limp-home air position of the throttle valve (30), from which the throttle valve (30) can be moved through rotation of the driver (15), a compensation spring (18), which has a definite initial stress force directed counter to the spring force of the clamping spring (13), is disposed between one spring end (131) of the clamping spring (13) and a catch surface (16) on one of the catches (14) in order to produce a rotary play-free state of the driver (12) in the limp-home air position (FIG. 4).
A device for restoring a throttle valve (26), which is for controlling combustion air of an internal combustion engine, into a definite limp-home air position, having a throttle valve shaft (11) that supports the throttle valve (26) and is rotatably supported in a housing (10), having a drivable driver (12), which is non-rotatably supported on the throttle valve shaft (11), and having a prestressed clamping spring (13), whose spring ends (131, 132), by simultaneously embracing a housing catch (14) affixed to the housing (10) and a driver catch (15) affixed to the driver (12) on opposing catch surfaces (16, 17) of the catches (14, 15), fix the limp-home air position of the throttle valve (26) from which the throttle valve (26) can be moved through rotation of the driver (12), characterized in that a compensation spring (18), which has an initial stress force directed counter to the spring force of the clamping spring (13), is disposed between one spring end (131) of the clamping spring (13) and a catch surface (16) on one of the two catches (14, 15).
