Method and device for electro-hydraulic pressure adjustment

摘要

The invention relates to a method and a device for adjusting the system pressure in a hydraulic circuit, the pressure to be controlled being converted into a displacement proportional to this, which is in turn converted into a force proportional to the displacement. This force acts against a magnetic force generated by a proportional magnet, an adjusting element being adjusted on the basis of a force comparison in such a way that the desired change in pressure is brought about.
