Abstract
A multi-port valve is disclosed having a ball bearing support system for a stator/rotor/valve stem assembly within a valve housing. Slipper seals or alternatively, poppet seals, connect a plurality of apertures situated in the rotor and a plurality of apertures situated in the adjoining stator so that a common central fluid receiving channel of the stator can be connected to a peripheral fluid delivery channel of the stator via a transfer channel in the rotor. The valve assembly provides a durable, virtually leak-proof system for delivery of a variety of fluids through the same delivery channel.
