ABSTRACT:
A rotary valve in which a chamber has one or more circular ports opening into the chamber. A ball of flexible resilient material is journaled on the offset end of a bell crank shaft extending into the chamber. Rotation of the shaft rotates the axis of the ball around the inside of the chamber, moving the ball from port to port. When engaged with the port, the ball expands into the opening sealing off the port.
