Abstract
The present invention is an improved 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 opening a path through a chamber in the gain valve and a bypass passage to prevent a sudden pressure buildup in the hydraulic booster at the gain valve when the hydraulic booster is operated in a manual mode and the fluid pumping means is suddenly started.
