<p>For controlling pressure at the outlet of a pump and for positioning the pedal during brake slip regulation, an auxiliary aggregate containing a transmission piston (5) and a shut-off valve (30) is added to the master cylinder. The pressure in the brake line (18') is applied to the closure element of the shut-off valve through a valve piston (28) against the pressure at the outlet of the pump. The pressure on the valve closure element is therefore equalized, and hence no forces are transmitted to the tappet (37). Consequently, the ramp (40) at the transmission piston (5) need not be specially hardened.</p> |
