The present invention relates to an automotive vehicle brake system with wheel slip control which is provided with a so-called filling valve, i.e., a non-return valve, between a secondary and a primary circuit. Initially, both circuits are evacuated for filling the brake system with pressure fluid, and evacuation of the secondary circuit is effected by way of the non-return valve that opens. The present invention suggests providing this valve with a blocking device which becomes effective when the brake is actuated for the first time, thereby causing pressure build-up in the primary circuit. The blocking device retains the valve closure member on the valve seat member, with the result that the non-return valve remains closed in the normal operation of the brake system. It is prevented by this provision that vacuum develops in the secondary circuit during a braking operation.

[ What is claimed is:] [1.]1. Non-return valve for use in a slip-controlled hydraulic brake system, comprising:a valve seat member,an elastically yielding valve closure member,a blocking device which cannot be released, during use of the brake system, and which, in the blocking condition, is appropriate to keep the valve closure member in a closed position on the valve seat member, in which the elastically yielding valve closure member is almost completely compressed in abutment on the valve seat member, wherein the blocking device cooperates with the valve seat member in frictional or form-locking engagement therewith.
