Abstract
The present invention is a gain valve for a hydraulic booster which allows transition from a manual braking mode to a power assist braking mode without the control called for in the manual mode immediately applied when the power assist function begins to operate. This is accomplished by a bypass passage through the gain valve piston which prevents a pressure increase in the hydraulic booster for power assisted braking. The bypass passage automatically opens and resets in response to system pressures.
