Granted: 1996-09-17
Abstract: A pipe coupling includes a contractible housing 10, which receives an elastomer sealing sleeve 32 of C-shaped cross section, having sealing lips 36 extending towards each other. A meander-like spring ring 44, which is U-shaped in cross section and is provided with slots 74, is inserted in to the respective annular groove 42 in order to support the sealing lip 36 against the sleeve bar 34. Upon the contraction of the housing 10, the sleeve 32 is upended in the peripheral direction and the sealing lips 36 are brought to bear snugly against the pipe wall 55. At the same time, the spring ring 44 contracts as a result of a decrease in the width of the slots 74. The sealing lip 36 is supported by the spring ring 44 over a large area, and the flowing of material of the sleeve 32 in and through the slots 74 is prevented. The spring leg 68 projecting over the sealing lip 36 prevents any sticking of the torus 56 to the sleeve bar 34. This pipe coupling is suitable for use under high operating temperatures and large temperature changes.

Title: Seal arrangement
Inventor: KLEIN NORBERT
IPC: F16J15/3252
Filed: 1993-11-04
Granted: 2001-01-09
Abstract: Seal arrangement for the sealing of a rotatable shaft extending through a bore in a housing wall includes a seal ring which has at least one sealing lip of elastomeric material for sealingly engaging the shaft along its outer circumference, first and second stiffening rings, an elastic intermediate coating and an anti-friction bearing. The first stiffening ring is L-shaped in cross-section with a radially outwardly directed first leg and an axially extending second leg. The anti-friction bearing is fitted in radial direction between the shaft and the second leg.  The sealing lip is fixed to the first leg. The second leg at least partly overlaps and tightly engages an outer ring of the anti-friction bearing and is surrounded on the side directed towards the bore wall by the second stiffening ring. The inner ring of the anti-friction bearing is supported on the shaft and the outer ring is retained by the second leg. The coating is made of an elastic, rubbery material which extends intermediate the first and second stiffening rings and over the second leg extends in radial and axial direction beyond the second stiffening ring subsequent to manufacture for improved sealing at the bore wall. That portion of the coating which extends in radial direction beyond the second stiffening ring subsequent to manufacture is compressed upon insertion of the seal arrangement into the bore. The second stiffening ring is radially stressed so that it forces against the bore wall to retain the seal arrangement in the bore by friction during the intended use. The seal arrangement has improved operating characteristics over a long service period, improves the guiding of the shaft in the region of the seal and provides for the insulation/damping of vibrations of the rotating shaft during use.
