  • Patent number: 6264205
    Abstract: A rotary cartridge seal includes a cold flowable plastic ring having a body for sealably engaging a housing bore and a lip for sealably engaging a shaft rotating within the housing bore. A spring is provided and disposed between the body and the lip for biasing the lip against the shaft and a separable metal retainer is provided for fixing the plastic ring within the housing bore and around the shaft. The separable metal retainer includes a surface of revolution with a rear portion having a radius suitable for press fitting into the housing bore and a front portion of lesser radius ending the ring. An internal groove is provided in the body of the plastic ring for engaging the ring in order to latch the plastic ring and metal retainer together. A spring portion connecting the retainer rear portion and the ring is provided for controlling residual stress in a radial direction within the plastic ring and preventing shrinkage of the plastic ring toward the shaft.

  • Patent number: 5992856
    Abstract: A seal assembly suitable for static, rotary and reciprocating sealing between the shaft and the housing is provided and includes a seal ring in the shape of an annulus having a body portion with an inside flange and an outside flange extending axially therefrom and establishing a ring seal cavity therebetween. An inside annular spring is disposed in the cavity for biasing the inside flange against the shaft to provide the dynamics seal therebetween. An outside annular spring is also disposed in the cavity for biasing the outside flange against the housing to provide a static seal therebetween and prevent the rotation of the seal ring. A band is disposed in the cavity in between the inside and outside springs for enabling the inside and outside springs to independently bias the inside flange and outside flange, respectively.

  • Patent number: 5984316
    Abstract: A seal assembly is provided for static, rotary and reciprocating sealing between the shaft and the housing. The seal assembly includes a ring seal in the shape of an annulus having a body portion with an inside flange and an outside flange extending longitudinally therefrom. A spring is disposed between the flanges for radially biasing the flanges from one another to effect sealing between the shaft and the housing and a circular band disposed between the spring and the outside flange is provided for maintaining radial force against the outside flange to retain the ring within the housing and provide static sealing between the ring seal and the housing despite shrinkage of the fluoropolymer seal ring.

  • Patent number: 5979904
    Abstract: A seal assembly is provided for rotary and reciprocating sealing between a shaft and a housing. The seal assembly includes a seal ring in the shape of an annulus having a body portion with an inside flange and an outside flange extending longitudinally therefrom. A body portion of the seal ring has a smooth cylindrical exterior surface and the seal ring is formed from a compressible moldable material. A spring is provided and disposed between the flanges for outwardly biasing the flanges from one another to enable sealing between the shaft and the housing. A band is provided and disposed externally around the body portion for holding the seal ring within the housing. A bond is provided between the band and the seal ring by way of striations and grooves which enable the seal ring material to compressibly mold into the band to provide a bond therebetween.
