  • Patent number: 4557293
    Abstract: An arrangement for controlling an electro-hydraulic valve having an armature of the magnet which performs a greater displacement stroke than the closure body of the valve and, following on the switching movement of the valve, initially tensions a spring buffer arranged between the armature and a push-rod switch. The armature rests directly in contact against a housing of the valve in the switched position, thus generating a remanence force, and, after completion of switching, the voltage applied to the coil of the magnet is reduced by electronic means to an extent such that the closure body of the valve is held in the switched position by the combined magnetic force induced by the reduced residual voltage and the remanence force. The initially-tensioned spring buffer, on switching off the residual voltage, generates an air-gap which eliminates the remanence force between the housing and the armature so that the closure body of the valve is then returned to the starting position by the valve force.
