ABSTRACT:
A load conscious brake pressure reduction valve is mounted between the suspension arm (1) and the suspension spring (5) of a vehicle. The control piston (8) of the valve is directly loaded with a force equal to the suspension spring load less the force of a compensating spring (12). To enable the valve to close against this load the area (A) of the control piston is made large. The movement required to effect valve closing is made small by careful control of the projection of the valve opening pin (26) and of the length of the valve seat member (20).
