[ I claim:] [1.] Hydraulic brake system with slip control, of the type includinga braking pressure generator which is hydraulically connected to at least one wheel brake by way of a main pressure line,a return line connected to said at least one wheel brake and to a pressure fluid collecting means,an auxiliary pressure pump having an auxiliary pressure line hydraulically connected to the braking pressure generator,inlet valves and outlet valves inserted in the main pressure line and the return line,a controllable restrictor inserted in the main pressure line between the inlet valve and the wheel brake which establishes an unimpeded hydraulic fluid passage in the main pressure line to said at least one wheel brake in a first switched position and limits the pressure fluid passage to the wheel brake in another switched position, comprising:a valve accommodating member;a valve carrier being received in said valve accommodating member and having an annular chamber therein;an annular piston being received in said annular chamber of said valve carrier and being axially movable relative to said chamber, wherein said annular piston accommodates said controllable restrictor; anda closure member for said inlet valve also being received within said valve carrier.
