Inventor: KATAGIRI MASAYOSHI
IPC: B60T13/56
Filed: 1995-03-30
Abstract: PURPOSE: To improve a brake feeling in shortening a stroke ranging from the nonoperating state of a vacuum servo unit to the operating one by making the center of an almost semispheric air controlling seat part to be installed at the rear end of a valve plunger, eccentric in the orthogonal direction of an axis of this valve plunger. CONSTITUTION: When a brake pedal is operated and a push rod 41 is moved to the left, the upper part of a seal part 611 of a control valve 61 comes into contact with the upper part of a vacuum controlling seat part 151e of a power piston 151, interrupting an interconnection between a constant pressure chamber and a variable pressure chamber. Subsequently the lower part of an almost semispheric air controlling seat part of a valve plunger 421 separates from a lower part of the seal part 611 and the atmosphere flows into the variable pressure chamber, and thereby a movable wall and the power piston 151 produce an extent of operating force due to differential pressure, driving a master cylinder.  At this time, the air controlling seat part is made eccentric to an axis of the valve plunger 421 in the orthogonal direction, and an amount of travel of the push rod 41 is reduced to some extent, whereby brake responsiveness is improved in this way.
