Abstract
In a pneumatic brake booster, positive and variable pressure chambers on opposite sides of a spring loaded diaphragm piston both communicate with an air pressure source under inoperative condition of the booster; only the positive pressure chamber communicates with the air pressure source while the variable pressure chamber communicates with atmospheric pressure in response to activation of the booster to operate the piston.
