Abstract
An adjuster for an adjusting device which pivots about a pivot shaft, particularly for a throttle valve of an internal combustion engine. The adjuster has an electric control motor for pivoting the adjusting device and a safety restoring unit for moving the adjusting device to a defined basic position upon an interruption to the supply of power to the control motor. To produce the power consumed by the control motor and associated with this to reduce its structural size and weight, the restoring unit is embodied such that its restoring force acting upon the adjusting device is effective solely upon an interruption to the supply of power to the control motor.
