ーキ倍力装置。A power booster including a regulator linked to a brake pedal and a power piston that amplifies pedal depression force and transmits it to a mask cylinder; a secondary pressure control unit that controls the supply pressure of working fluid supplied to the power booster; , a secondary pressure setting section for setting the supply pressure to be controlled by the secondary pressure control section, one end of which is partitioned off by a diaphragm and the other end of the regulator that is movably provided on the power piston via a spring. A pilot pressure chamber provided with a nozzle is formed at an end facing the power piston, and communicates with the pilot pressure chamber, into which a portion of the supply pressure is introduced by relative movement between the power piston and the regulator. What is claimed is: 1. A brake booster comprising a pilot flow path and a valve that contacts the diaphragm and supplies and discharges the supply pressure to and from the power piston, which is actuated by a pressure change in the pilot pressure chamber.
