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.
Claims20
A multi-port valve comprising:
- a valve housing having a first housing aperture, second housing aperture, an annular housing chase situated about the second housing aperture;
- a valve stem having an annular flange sized to matingly engage the first housing aperture and a main valve stem body sized to matingly engage the second housing aperture such that the valve stem rotates freely within the housing;
- a rotor dimensioned to fit within the first housing aperture and having at least one rotor fluid receiving aperture and at least one rotor fluid delivery aperture wherein the rotor fluid receiving aperture is in fluid communication with the rotor fluid delivery aperture via a transverse channel;
- a stator having at least one stator fluid receiving aperture and at least one stator fluid delivery aperture wherein the stator is sized to matingly engage the first aperture of the housing;
- and,
- an actuator secured within the rotor fluid delivery aperture.

- a rotor dimensioned to fit within the first housing aperture and at least one rotor fluid receiving aperture and at least one rotor fluid delivery aperture situated within a rotor neck extending from a top surface of the rotor wherein the rotor fluid receiving aperture is in fluid communication with the rotor fluid delivery aperture via a transverse channel;
- a stator having at least one stator fluid receiving aperture and at least one stator fluid delivery aperture formed within a stator post extending from a top surface of the stator, the stator post further comprising a bore dimensioned to receive the rotor neck, wherein the stator is sized to matingly engage the first aperture of the housing;
- an actuator secured within the rotor fluid delivery aperture, and,
- a vent bore formed in a sidewall of the valve housing.
