  • Patent number: 6015152
    Abstract: A sealing assembly is disclosed for creating a seal between first and second mating members or components. The sealing assembly basically includes a seal retainer with one or more annular seals coupled thereto. The seal retainer including a substantially flat body portion lying in a plane and with at least one resilient retaining element integrally formed with said body portion as a one-piece, unitary member for engaging the seal(s) to retain the seal(s) thereto. The seal retainer has an indicator formed on its body portion to indicate if the seal retainer has been used. In the preferred embodiment the indicator is a raised protrusion which normally extends outwardly from the plane of body portion of the seal retainer. Once the seal retainer is used, the raised protrusion of the indicator is deformed inwardly into the plane of the body portion of the seal retainer.

The sealing assembly basically includes a seal retainer with one or more annular seals coupled thereto. The seal retainer including a substantially flat body portion lying in a plane and with at least one resilient retaining element integrally formed with the body portion as a one-piece, unitary member for engaging the seal or seals to retain the seal or seals thereto. In the preferred embodiment, the seal retainer is folded to form three layers. In particular, the body portion of the seal retainer has a main supporting layer with four tabs foldably coupled thereto.

  • Patent number: 5735532
    Abstract: A sealing assembly is disclosed for creating a seal between first and second mating members or components. The sealing assembly basically includes a seal retainer with one or more annular seals coupled thereto. The seal retainer includes a body portion constructed of three layers. The inner layer is designed to retain the seal or seals thereto, while the outer layers or plates are designed to limit the amount of seal compression. The inner layer has at least one resilient retaining element integrally formed therewith as a one-piece, unitary member for engaging and retaining the seal or seals to retain the seal or seals thereto.

  • Patent number: 5730448
    Abstract: A sealing assembly is disclosed for creating a seal between first and second mating members or components. The sealing assembly basically includes a seal retainer plate with one or more annular seals coupled thereto. The seal retainer plate includes a substantially flat rigid body portion with at least one resilient retaining element integrally formed therewith as a one-piece, unitary member for engaging and retaining the seal or seals thereto. Preferably, the seal retainer plate is constructed of a non-metallic material. The body portion of the retainer plate has a thickness relative to the axial dimension of the seal or seals for limiting axial compression of the seal or seals.
