Druckreduzierventileinrichtung für Kraftfahrzeuge

摘要

A pressure reducing valve device includes an adjusting spring for changing its length by a first screw member and a valve stem rotatable by a second screw member so as to control a spring ratio, and a load sensing reducing valve movable on a bracket so as to align a piston with the valve stem by a third screw member whereby the pressure reducing valve device controls a fluctuating width of dynamic characteristics so as to match with an ideal braking line of any of an empty, loaded and surplus loaded vehicle.
