ABSTRACT:
A pump-out control valve for use in connection with a wet/dry vacuum cleaner that includes a collection tank, a top cover and a vacuum blower with an air inlet and air outlet. The control valve is mounted over a pair of openings formed through the cover. The valve includes a manifold plate located over the pair of openings and spaced above the cover, and a valve rotor located between the manifold plate and the cover. The plate is provided with an air inlet fitting and an air outlet fitting that are connected through flexible hoses to the centrifugal blower. The fittings are in general alignment with the openings in the cover. The rotor has one through passage for connecting the manifold plate inlet with one of the openings through the cover and one lateral passage which is adapted to divert flow laterally and at the same time, block the other opening in the cover. The rotor is turned approximately 180.degree. between two positions for either causing a vacuum in the tank or for pressurizing the tank for pumping out the liquid accumulation.
