Abstract

A solenoid valve for controlling the braking pressure of a wheel brake of a slip-controllable hydraulic brake system of a motor vehicle includes an armature, a valve insert, a valve seat, a valve element, and a spring device. The valve element is arranged in the valve insert in a longitudinally displaceable manner and acts together with the valve seat. The spring applies a force acting in the direction of opening with respect to the valve seat to the valve element in the installed position. The valve element can be actuated by an electromagnetic actuator in the closing direction with respect to the valve seat. The valve element is arranged between an anchor and the valve seat and is operatively connected to the anchor. A front face of the valve element facing the anchor has at least one projection and the projection defines a point of contact with the anchor.
