Electromagnetic valve in seat valve design for slip-controlled hydraulic motor vehicle-brake systems, has valve closing body, which is arranged in valve housing, and magnet armature, whose front surface is provided with though-hole

摘要

The electromagnetic valve has a valve closing body (7,8), which is arranged in a valve housing (1), and a magnet armature (15), whose front surface (10) is provided with a though-hole (11). A cavity (20) reducing the contact surface of the magnet armature at the valve closing body is provided between the annular surface (4) of the magnet armature and the front surface of the valve closing body on abutment of the magnet armature at the valve closing body. The adhesion of the front surface on the annular surface is prevented.
