ABSTRACT:
A pressure control device for brake systems of automotive vehicles. The device includes a stepped control piston (5) which is guided axially displaceably within a housing (1, 2) and which, cooperating with a valve element (14), controls the pressure medium passage between an inlet chamber (8) and an outlet chamber (9). The smaller diameter portion (6) of the control piston (5) is associated with the inlet chamber (8) containing the valve element (14). In order to optimally adapt the control characteristic to the specific requirements of the vehicles it is provided that the valve element (14) is applied by a displaceable stop (17).
