ABSTRACT:
A valve is used in a system employed on a vehicle for effecting the selected automatic disengagement of the transmission or main clutch upon the application of the vehicle service brakes, as well as the reengagement of the transmission when the brakes are released. Such valve allows rapid pressure buildup to the brakes, so that they may be rapidly applied, but delays the release of the brakes to allow ample time for reengagement of the transmission.
