摘要： A sealing assembly includes a seal support having a support ring made from an elastomeric material, at least one seal element having a ring made from a polymer material, and an abutment ring against which a radial portion of the seal element axially abuts. The seal element is connected in a materially-bonded manner to the support ring along a first radially outer portion of the seal element, and the seal element axially abuts on the abutment ring along a second radially inner portion of the seal element. The seal element and the abutment ring are free of any connection along the second radially inner portion of the seal element.

摘要： A radial-shaft sealing assembly includes a sealing lip disposed on a support ring. A cylindrical portion of the sealing lip that abuts on a rotatable shaft contains an elastomeric material and has a profiling for pumping oil or lubricant back to an oil side of the sealing assembly. The profiling includes first and second annular ridges disposed in parallel, and first and second groups of radially-projecting pumping elements disposed therebetween and distributed around the circumference of the cylindrical portion. Each pumping element extending at an angle (α) to the circumferential direction (U) of the cylindrical portion, but the first group of pumping elements has an opposite orientation to the second group of pumping elements.

摘要： A sleeve is configured to be fitted onto a rotating shaft and the sleeve includes a tubular portion extending in an axial direction and having a cylindrical-shaped sealing guide surface configured to contact a radial shaft seal. A flange extends outward from the tubular portion at least substantially in a radial direction that is perpendicular to the axial direction. A first target break line is defined between the tubular portion and the flange and is configured to facilitate separation of the flange from the tubular portion. Further, a second target break line is defined in or on the flange and is configured to facilitate tearing of the flange at least substantially in the radial direction of the flange up to the first target break line.

摘要： A seal for a compressor for sealing a shaft includes a first seal part of a first material, a second seal part of a second material different from the first material, and a stiffening part. The second seal part is connected at least with a radially extending surface area to at least one of the other parts and the surface area of the second seal part opposite the aforementioned surface area is kept from making contact with the stiffening part. The first seal part is provided, toward the axial side, with a sealing lip which is adapted for sealing contact with the shaft, and the second seal part is made such that the radially inner area of the second seal part extends axially and is free from collision with the sealing lip when the seal is properly installed.

摘要： A valve stem seal (1) seals a valve stem (4) that is reciprocally movable in an axial direction. The valve stem seal includes a base body (8) that is connectable with a valve stem guide (6). A first seal lip (10) is resiliently positioned relative to the base body via an elastic connection (16) and seals the valve stem relative to an oil chamber (24). A second seal lip (12) is spaced in the axial direction (2) from the first seal lip and seals the valve stem relative to a gas chamber. The second seal lip is also resiliently positioned relative to the base body via the elastic connection.
