The invention relates to a solenoid valve, particularly for controlling the brake pressure of a wheel brake of a slip-controllable hydraulic brake system of a motor vehicle. In known solenoid valves, there is a first hydraulically effective connection of an armature chamber of the solenoid valve to an outlet through the guide of a tappet in a valve insert. The first hydraulically effective connection ends in the form of a blind hole and thus does not permit flushing out gas bubbles which possibly have accumulated in the armature chamber. In order to solve this problem, the invention proposes a second hydraulically effective connection which is arranged away from the guide of the tappet, uncoupled from the first hydraulically effective connection. Thus, a closed pressure medium path is effected within a valve cartridge of the solenoid valve, the closed pressure medium path making possible an effective flushing of the armature chamber and thus a flushing out of gas bubbles.
