Fast-acting valve for working as a hydraulic valve has a valve slide in a valve sleeve with an electromagnet and a readjusting spring both capable of driving the valve slide in an opposite direction

摘要

A valve slide (4) can move into two different closing positions. A readjusting spring (11) has a second parallel less rigid spring (13) and can be pressed together only over partial areas of the path of the valve slide. An electromagnet (2) can be excited in two stages via a control device. For each stage the electromagnet has different windings to be excited by separate currents.
