1. A hydraulic unit for a hydraulic brake system, the hydraulic unit comprising:
a hydraulic block; and
at least one valve apparatus including;
a hydraulic cartridge with a valve seat and a displaceable closing body configured to block and unblock the valve seat;
a magnet assembly with a magnet coil configured to generate a magnetic force that displaces the closing body, the magnet assembly being integrated into the hydraulic block;
a movable magnetic armature carrying the closing body and configured to move in response to the magnetic force;
a spring arranged to exert a pressure force on the movable magnetic armature toward the valve seat; and
a permanent magnet configured to assist the displacement of the closing body via the magnetic force, said permanent magnet defining a perforation in which the spring is disposed, and said permanent magnet disposed within a magnet receiver defined in said movable magnetic armature.
