Abstract
A seal assembly (10) includes a relatively rigid seal holder (12) and a relatively soft O-ring seal member (14). The seal member (14) is disposed in an annular groove (16) in the seal holder (12). A plurality of ribs (70) are disposed between the seal member (14) and the bottom (76) of the annular groove (16) in the seal holder (14) to retard rotation of the seal member (14) relative to the seal holder (12). In one embodiment of the invention, the ribs (70) are integrally formed as one piece with the seal holder (12) and engage an outer side surface (72) of the seal member (14). In another embodiment of the invention, the ribs (70) are integrally formed as one piece with the seal member (14a) and engage a smooth arcuate bottom of an annular groove in a seal holder. In another embodiment of the invention, both the seal holder (12) and the seal member (14a) are provided with ribs (70 and 70a).
