常に正確に行うことができる。Means for Solving the Problems According to the present invention, the above-mentioned problems are solved by the configuration shown in the characteristic part of claim 1. It is advantageous to connect a switch and a limiting resistor connected in parallel with a diode to the electromagnetic coil of the regulating element, and to connect a storage capacitor to these resistors and the diode. This storage capacitor receives the current flowing through the coil after the switch is opened and is charged with this current. The size of this capacitor is advantageously chosen such that the voltage present across it is not higher than the voltage value of the operating DC power supply of the device, since otherwise the load, i.e. the electromagnetic This is because reverse currents may occur through the coil.The use of computers allows for a simple and inexpensive construction of the output stage provided for the regulating element and makes the regulating operation very precise. It can be carried out.
