Abstract
In an electropneumatic field device for controlling a pneumatic actuator, an energy transducer is provided which converts pneumatic energy into electrical energy. The energy transducer has a working chamber with a pneumatic compressed air inlet via which a compressed air impulse is introduced, a reset chamber, a coil, an armature separating the working chamber and the reset chamber and guided for translational back and forth movement, and a permanent magnet so that electric energy is induced in the coil. The pneumatic compressed air inlet is configured such that the compressed air impulse leaving the compressed air inlet has an inflow direction angle into the working chamber which has an axial angular direction component which is parallel to a translational axial movement direction of the armature.
