Abstract

A bistable solenoid valve for a hydraulic brake system has a guide sleeve in which an upper immovable pole core is fixedly arranged and a closing element is displaceably arranged. The closing element is forced into a valve seat during a closing movement and lifts off from the valve seat during an opening movement, and is fixedly connected to a magnet assembly. An actuation of the movement of the closing element is performed by the magnet assembly via a coil positioned around and substantially surrounding the guide sleeve. A lower immovable pole core is fixedly arranged in the guide sleeve and the magnet assembly is positioned between the lower and the upper pole core.
