Abstract
The invention concerns a device for determining the position of a linearly displaceable element (2) for controlling construction components, particularly for determining the position of a valve piston (1) of a bypass valve of an exhaust gas-recirculation system (also called EGR) where the linearly displaceable element (2) can be displaced in both directions of motion with the help of a device, preferably an electric motor with interconnection of a drive and an oscillating crank (3), or a pneumatic, hydraulic or electromagnetic actuator, whereby in accordance with the invention for the determination of the position of the linearly displaceable element (2), a magnet and a Hall sensor (5) or a rotation-sensitive magnetic sensor element are used.
