  • Hydraulic Control Valves For Brake Systems (AREA)

Abstract

PURPOSE: To compensate for the shortage of braking force for an entire vehicle, by suspending the reduction control of rear wheel brake pressure, which is effected during normal operation, when one system is defective.
CONSTITUTION: A control piston 10 and a balance piston 7, which constitute the separate valve mechanisms of liquid pressure systems for double piping, are connected to each other through a fail-safe clip 30 to restrict the relative separation within a prescribed length of l1. The control piston 10 is caused to collide against a fail-safe piston 5 through the fail-safe clip 30. When one system is defective, the balance piston 7 is moved rightward to restrict the leftward motion of the control piston 10 through the clip 30 to connect an input and an output liquid chambers a1, a2 to each other.
