Abstract: A bleeder valve assembly for a dual hydraulic brake system having dual hydraulic lines with independent fluid reservoirs. The bleeder valve assembly includes a hydraulic chamber communicating with both of the hydraulic lines, and containing a primary valve element for controlling the bleeding of hydraulic fluid from the dual lines via the chamber. A pair of secondary valve elements are mounted within the chamber, each cooperating with one of the dual hydraulic lines. A rubber grommet biases both of the secondary valve elements against the fluid pressure in the dual hydraulic lines, and a bleeder screw is associated with the grommet to control the bleeding of fluid from the lines into the chamber.

Abstract: A POWER UNIT FOR A BRAKE SYSTEM INCLUDING A CASING HAVING A POWER WALL MOVABLE WITHIN THE CASING IN RESPONSE TO DIFFERENTIAL PRESSURES ACROSS THE WALL FOR ACTUATING THE PISTON OF A MASTER CYLINDER. THE POWER WALL IS FORMED BY A PAIR OF OPPOSED PRESSURE PLATES WHICH ARE MOUNTED ON A SUPPORTING MEMBER, AND A REACTION MECHANISM IS MOUNTED WITHIN THE SUPPORTING MEMBER. THE TWO PRESSURE PLATES FORM A FLUID CHAMBER WITHIN THE POWER WALL. FOR THE PURPOSE OF CONTROLLING THE DIFFERENTIAL PRESSURE ACROSS THE WALL, A VALVE IS MOUNTED WITHIN THE WALL AND OFFSET FROM THE LONGITUDINAL AXIS OF THE UNIT, WITH THE VALVE BEING OPERATED BY A LEVER EXTENDING LATERALLY FROM A LONGITUDINAL CONTROL MEMBER.
