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.

The invention relates to a valve cartridge for a solenoid valve, having a capsule, a valve insert that is inserted by a first end into the capsule and on its other end receives a valve body with a main valve seat. A lower valve part is axially braced on the valve insert, and a flat filter for filtering out dirt particles is connected via a retaining element to the lower valve part. According to the invention, the retaining element includes at least one component on the flat filter side and at least one corresponding component on the lower valve part side, which makes at least one partial clamping connection between the flat filter and the lower valve part. The invention further relates to a solenoid valve having such a valve cartridge.

The present invention relates to a two-stage valve for controlling fluids, in particular a hydraulic fluid. The valve includes an actuating element, a pilot stage having a first valve seat and a first closing body, which is connected to the actuating element, and a main stage having a second valve seat and a second closing body. The second closing body is provided with a fastening region and a main region having a passage opening. The first valve seat is arranged at the passage opening. The second closing body is connected to the actuating element via the fastening region. The fastening region is designed elastically in such a way as to open the pilot stage by elastically deforming during actuation of the actuating element.
