Press seal

摘要

An elastomeric seal suitable for use in sealing non-circular cylinders of hydraulic presses against loss of the working fluid. This seal is an elastomeric (e.g. rubber) seal having a generally L-shaped cross section. One portion of the seal functions as a support portion and includes longitudinally extending ribs along its inner face for engaging in a sealed relationship with a supporting structure. The other portion of the seal acts as a wiping portion in engagement with the moving cylinder. The wiping and support portions come together in a generally perpendicular relationship to form a rounded nose where their outer faces meet and a reinforcing fabric is formed into the seal along its outer surface and extending across the nose of the seal.
