  • Patent number: 6626437
    Abstract: A wiper seal for a hydraulic component is provided. The wiper seal includes a support member and a body portion. The support member includes a first leg having an inner surface, a first end, and a second end. The first leg extends substantially parallel to a reference axis. A second leg having an outer surface extends substantially perpendicular to the reference axis from the first end of the first leg. The body portion defines an opening therethrough and includes an outer peripheral surface configured to receive the inner surface of the first leg of the support member, a first radial face extending substantially coplanar to the outer surface of the second leg, an inner surface disposed at an angle relative to the reference axis and extending to a lip adjacent the first radial face, and a second radial face extending generally perpendicular to the reference axis from the second end of the first leg of the support member.

  • Patent number: 6609716
    Abstract: A wiper seal for a hydraulic component is provided. The wiper seal includes a support member with a first leg that has an inner surface, a first end, and a second end and that extends substantially parallel to a reference axis. The support member further includes a second leg that has an outer surface extending substantially perpendicular to the reference axis from the first end of the first leg. The wiper seal also includes a body portion that defines an opening therethrough and includes an outer peripheral surface configured to receive the inner surface of the first leg of the support member. A first radial face extends substantially coplanar with the outer surface of the second leg and a second radial face extends generally perpendicular to the reference axis from the second end of the first leg of the support member. The second radial face includes a cutout defining a first cavity. An inner surface defines a first sealing lip adjacent the first radial face.

    Abstract: A wiper seal for a hydraulic component is provided. The wiper seal includes a support member with a first leg that has an inner surface, a first end, and a second end and that extends substantially parallel to a reference axis. The support member farther includes a second leg that has an outer surface extending substantially perpendicular to the reference axis from the first end of the first leg. The wiper seal also includes a body portion that defines an opening therethrough and includes an outer peripheral surface configured to receive the inner surface of the first leg of the support member. A first radial face extends substantially coplanar with the outer surface of the second leg and a second radial face extends generally perpendicular to the reference axis from the second end of the first leg of the support member. The second radial face includes a cutout defining a first cavity. An inner surface defines a first sealing lip adjacent the first radial face.
