Abstract:
A unique valve door mechanism is disclosed for use in a dual chambered utility type vacuum cleaner having two suction inlets whereby the inactive suction inlet may be selectively closed and sealed off from the atmosphere. The valve door is slidingly suspended between guide rails whereby the door may be selectively positioned adjacent the suction inlet to be disabled. Atmospheric pressure is utilized to urge the valve door against the selected inlet opening thereby sealing off the inlet from the atmosphere. The valve may also be in the form of a rotatable, elbow-shaped body having a single plenum. The body may be rotated between at least two positions where the outlet to the plenum is in fluid communication with a wet tank in one position and a dry tank in the other position.
