<P>PROBLEM TO BE SOLVED: To provide an improved hydraulic brake booster system. <P>SOLUTION: The hydraulic brake booster system includes: a primary piston axially moveable within a bore of a cylinder; a booster chamber located rearwardly of the primary piston within the bore; an input rod extending within the booster chamber; a booster vent path in selective fluid communication with the booster chamber; and a seal member located between the forward face and the primary piston. The seal member is in a fixed relationship with the input rod and configured to (i) seal the booster vent path from the booster chamber when the input rod is in a first position, and (ii) not seal the booster vent path from the booster chamber when the input rod is moved rearwardly within the booster chamber to a second position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
