摘要： A fluid pressure operated servomotor such as a vacuum booster including a power piston having a differential pressure acting thereacross, an input rod for actuating a valve mechanism mounted in the power piston, a reaction lever disposed between the power piston and an output rod for transmitting a force to the output rod and transmitting a reaction force to the input rod. A return spring for urging the power piston in the return direction acts through the reaction lever on the power piston, whereby the reaction force is not transmitted to the input rod until the force transmitted to the output rod exceeds a predetermined value.
