Abstract
A vacuum control valve includes a valve body defining a cavity, an inlet opening and a vent opening. A vacuum supply control member is movably mounted at the inlet opening, and is movable between an open position to open the inlet opening, and a closed position to close the inlet opening. A vent control member is movably mounted at the vent opening, and is movable between an open position to open the vent opening, and a closed position to close the vent opening. The vacuum supply control member and the vent control member are movable independently of each other, for selectively controlling the supply of vacuum when the vacuum supply control member is in the open position and the vent control member is in the closed position, and for selectively venting vacuum when the vacuum supply control member is in the closed position and the vent control member is in the open position.
