Abstract
A rotary distributor seal for a rotary centrifuge which comprises a tubular housing having sealed ends, a relatively rotatable fluid conveying apertured spindle coaxially mounted in the housing, and several resilient, spaced ring seals positioned about the spindle to seal the annular space between the spindle and the housing, and to subdivide it into several annular chambers. Ports communicate with the chambers to provide fluid flow from the ports through the separate chambers and through the spindle. In accordance with this invention, support members are positioned in alternate, spaced chambers between pairs of ring seals to prevent collapse of the ring seal pairs together.
