Abstract
PURPOSE: To simplify the construction of a brake booster and heighten its reliability, by transmitting a reaction force to both a ball retainer and a control piston but not to a power piston when the power piston is in its expanded position.
CONSTITUTION: When a power piston 4 is at its expansion end, the backward motion of a ball retainer 43 is blocked by the engagement of a ball 44 with a slope provided on the front part of a control piston 4. For that reason, the power piston 4 is not pushed back even after an energizing force reaches a limit. An idle stroke is thus prevented. A recess for the ball 44 has a bow-shaped cross section and extends toward the axes of the control piston 9 and the power piston 4 so that the ball 44 and the surface of the recess are in linear contact with each other. The contact pressure between the ball 44 and the surface of the recess is thus held down. This results in preventing both pistons 4, 9 from moving relative to each other.
