ABSTRACT:
A ring shaped seal (10) for preventing fluid flow through a gap (32) between a rotating shaft (30) and a cylindrical wall (34) is positioned in a groove (28) in the shaft. The seal has, in cross section, a generally rectangular body (11) that has a slightly lesser width than the width of the groove. The body has a first end wall (12) that includes first pockets (18) and a second end wall (14) that includes second pockets (20). The seal has an outer wall (22) with a contact portion (26) that is in abutting contact with the cylindrical wall. When a higher pressure is applied on one side of the seal, the end wall of the seal on the side away from the higher fluid pressure is pushed against a side wall of the groove. The pockets in the end wall of the seal that is pushed against the groove, are open to the higher pressure and exert a force which counteracts the forces pushing the end wall of the seal against the side of wall of the groove. The pockets also provide lubrication at the abutting walls of the seal and groove which reduces wear and extends seal life.
