ABSTRACT:
A structurally simplified 2/2-way shutoff valve having a parallel-connected pressure limiting valve. The shutoff valve has a first closing body that cooperates with a first valve seat. The first valve seat is embodied on a second closing body pierced by a conduit, which second closing body, under the influence of a spring, engages a second valve seat attached firmly to a wall which is secured to the housing. The biasing force of this spring is greater than a closing force exerted by an armature upon the first closing body and oriented in the opposite direction from the biasing force. The second closing body and the second valve seat form a pressure limiting valve, which is disposed in the housing of the shutoff valve. The invention is applicable to hydraulic motor vehicle brake systems having an anti-skid and traction control apparatus.
