Abstract

A bistable solenoid valve for a hydraulic brake system, includes a guide sleeve, in which an upper and a lower non-moving pole core are arranged fixedly and a closing element is arranged movably, wherein the closing element penetrates into a valve seat during a closing movement and lifts up from the valve seat during an opening movement. The closing element is connected fixedly to a permanent magnet, wherein the permanent magnet is positioned between the lower and the upper pole core. A coil group is positioned around the guide sleeve and substantially encloses the guide sleeve. The coil group includes at least two coils, wherein the coil group is configured in such a way that an actuation of a movement of the closing element takes place by means of an activation of the at least two coils.
