Abstract

A braking pressure control unit is disclosed, including a transmission lever acting on actuating tappets of a control valve, the lever is articulated through the intermediary of a first spring arrangement attached to a vehicle part which changes its position relative to the braking pressure control unit in a load-sensitive manner. Between the transmission lever and the control valve actuating tappets, a second spring arrangement is provided, which urges the transmission lever against a stop affixed to the housing. The transmission lever is adjusted to provide a clearance between the lever and the actuating tappets. When the setting of the load-sensitive transmission arrangement is clearance-free, incorrect adjustments of the control valve will not cause appreciable variations of the valve change-over pressure.
