Abstract

A solenoid valve, for controlling a brake pressure of a wheel brake of a slip-regulatable hydraulic brake system for a motor vehicle, includes a valve element, valve insert, valve seat, spring device, electromagnetic actuator, and armature. The valve element is longitudinally movably positioned at least partially in the valve insert, positioned between the armature and the valve seat, and configured to interact with the valve seat. The spring device, in an assembled position, has a force component acting on the valve element in an opening direction with respect to the valve seat. The electromagnetic actuator is configured to act on the valve element in a closing direction with respect to the valve seat. The valve element has a contact surface operatively connecting the valve element and armature, and configured such that a central axis of the valve element and the contact surface form a non-rectangular intersection angle.
