A hydraulic brake system with slip control, including a braking pressure generator hydraulically connected to at least one wheel brake by way of a main pressure line, a return line connected to the wheel brake and to the suction side of an auxiliary-pressure pump, an auxiliary-pressure line hydraulically connected to the braking pressure generator, and inlet and outlet valves inserted into the main pressure line and the return line and either closing or keeping open the pressure fluid passage in the main pressure line and in the return line, wherein a restrictor is controllable in the main pressure line between the inlet valve and the wheel brake permitting an unhindered hydraulic fluid passage in the main pressure line to the wheel brake in a first operating position, while the restrictor limits the pressure fluid flow to the wheel brake in another operating position.

A hydraulic brake control system with slip control, comprising: a 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 the wheel brake and to a pressure-fluid collecting means, an auxiliary-pressure pump having an auxiliary-pressure line and being hydraulically connected to the braking pressure generator, and inlet and outlet valves inserted into the main pressure line and the return line, said inlet valve including a valve closure member and a valve carrier having at least one transverse bore, a controllable restrictor connected to the main pressure line downstream of the inlet valve closure member, said restrictor adopting predetermined operating positions as a function of a defined hydraulic pressure difference between the wheel brake and the braking pressure generator, said restrictor permitting an unhindered hydraulic fluid flow in the main pressure line to the wheel brake in a first operating position, while limiting the pressure fluid flow to the wheel brake in a second operating position, and said restrictor being arranged on a piston in said inlet valve wherein said piston is guided by at least a portion of said valve carrier for selectively restricting flow through said transverse bore.
