Canted Rotary Seal.

Abstract

The patent application relates to a self-lubricating seal for rotary fluid seal applications in which an O-ring is mounted on a shaft disposed for rotation in a housing, with the O-ring axis canted to an acute angle with respect to an axis transverse to the longitudinal axis of the shaft. The shaft rotates within the O-ring and the canted axis causes it to wipe fluid, continually inducing self-lubrication. Canting the O-ring also causes a slight twisting action which gradually changes the surface wearing against the shaft.
