摘要： A rotary disc valve includes a guide assembly having a ring-shaped member having a groove disposed in an inner surface thereof, and a valve disc assembly rotatably coupled to the guide assembly. The valve disc assembly includes a valve disc, a projection received within the groove of the guide assembly, and a chimney support coupled to the guide assembly. The chimney support includes a seal member for selectively sealing against the valve disc. The groove has a main portion perpendicular to a longitudinal axis of the rotary disc valve, and an angled portion at an oblique angle with respect to the longitudinal axis. When the valve is moved between a closed and open positions the valve disc assembly is rotated and moves the projection along the angled portion of the groove, thereby moving the valve disc toward and away from the seal.
