Abstract
PURPOSE: To increase the braking force of rear wheels as compared with that at the time of normal operation of a controller, by releasing the operation of a valve mechanism in the other system under normal operation and always linking input and output liquid chambers when one of the two independent liquid pressure systems causes a failure.
CONSTITUTION: A tubular fail-safe piston 5 with stepped portions is slidably engaged into value cylinders 2, 3 with stepped portions and pressed rightward by a stopper spring 8 through a valve seat 6 and spring seat 7. A balance piston 12 is slidably engaged into said piston 5 to divide it into right and left liquid chamber a2, b2 which are linked to a rear wheel brake system repectively through output ports 14, 15. While in the cylinder 2, a control piston 16, in which one end is slidably engaged in a blind-holed cylinder 17 and the other end in the piston 5, is housed to construct a first valve mechanism of a system (a). Further a ball 25 that constitutes a second valve mechanism of a system (b) with a valve seat 26 of the piston 5 is provided and pressed leftward by a spring 27.
