Abstract: The invention relates to a seal on a disk valve, in which a sealing collar consisting of elastomeric material is used for both the static flange seals and the dynamic seals on the valve disk and on the switching pin, the sealing function of the static flange seals (14) being separate from the sealing function of the dynamic disk seal.

Abstract: A sealing arrangement includes: a sealing ring having at least one dynamically loaded sealing lip, the sealing ring including a core comprised of an electrically conductive material and a casing comprised of an electrically insulating material, the casing having a material thickness, surrounding the core at least in part and including the sealing lip; a machine element to be sealed that has a surface to be sealed, which surface is electrically conductive and surrounded by the sealing lip in a radially prestressingly sealing manner; and a wear detector, which has an electric measurement device for detecting a state of wear of the sealing ring. When viewed in section, the material thickness of the sealing lip is smaller in a radial direction than the material thickness of a remainder of the casing.

Abstract: A flange seal has a support body of a tough, hard material, and a sealing element of a rubbery-elastic material, that are interconnected in a single piece, the sealing element having a sealing edge that can be exposed to a medium to be sealed in a chamber to be sealed. In the state resulting from manufacture, the sealing element has cavities in the region of the sealing edge, which cavities vary in volume during use of the flange seal as intended.

Abstract: In an embodiment, the present invention provides a seal with at least one sealing lip to seal a gap between a machine component and a housing, including: a main body made from resilient material, the main body being equipped such that it is electrically conductive and is covered with a jacket made from an electrically insulating material on at least part of its outer side. The jacket is assigned to at least those regions of the main body that are in contact with the machine component and the housing.

Abstract: A seal assembly includes: a seal element; a part to be sealed; and a measuring arrangement for monitoring an aging of the seal element. The seal element is held on the part so as to provide a contact stress between the seal element and the part. The seal element has a contact face with which the seal element bears against the part. At least one measuring component of the measuring arrangement is integrated in each case into the seal element and into the part. The contact face of the seal element has a surface geometry with depressions.

Abstract: A sealing assembly includes: a first machine element and a second machine element, which delimit a gap; and a sealing element arranged in the gap, the sealing element sealingly laying against the second machine element under an elastic bias, the sealing element having a first section and a second section, the first section coming into contact with a medium to be sealed off. The sealing element includes at least one sensor, the at least one sensor detecting a contact pressure exerted by the sealing element. The at least one sensor is associated with the second section.

Abstract: A seal assembly includes: a first seal element; and a pressing element. The first seal element is a groove ring and has a first seal lip and a second seal lip. The pressing element is arranged between the first seal lip and the second seal lip and effects a radial pre-tensioning of the first seal lip and the second seal lip. The pressing element closes a gap between the first seal lip and the second seal lip.
