Abstract

See full text

Improved brake pressure control valve assemblies with a bypass function are proposed which have an axially slidable piston responsive to fluid pressures of two brake fluid circuits, and a pressure reducing valve mounted in the piston for reducing the pressure of one of the two brake fluid circuits. If one of the circuits fails, the piston is adapted to move toward the failed circuit to disable the pressure reducing valve from reducing the pressure of the other of the two circuits.
