Abstract

A solenoid valve for hydraulic brake units with slip control is described which has a magnetic armature (2) surrounded by a valve dome (14), the magnetic armature (2) positioned by energization of a magnet coil (16) , so that a valve needle (1) which is carried by the magnetic armature (2) is moved onto a valve seat (3). A hydraulic actuating force is generated by an arrangement causing the valve needle (1) to open even through the solenoid valve is energized causing the valve to act as a pressure relief or limiter valve.
