Abstract: A gas strut includes a housing, a rod, and a seal. The rod extends along a centerline and is spaced radially inward from the housing to axially move between a retracted position and an extended position with respect to the housing. The seal includes an outer portion engaged to the housing, an inner portion in sliding contact with the rod, and a mid-portion spanning between and engaged to the inner portion and the outer portion during normal operation. The mid-portion is constructed and arranged to break after about a predetermined number of gas strut actuations.

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 sealing device includes a conductive member integrated with a seal lip along a circumferential direction of the seal lip and configured such that a voltage is applied to the conductive member, and a reference member provided at a predetermined interval with respect to the conductive member. A deformation degree of the seal lip is inspected such that a change of an inductance of the conductive member associated with a change of the interval between the conductive member and the reference member is detected by a detection unit.

Abstract: A seal device for sealing in a liquid medium includes a first seal assembly disposed on a primary side facing the medium and configured to seal a stationary component with respect to a rotatable component, a second seal assembly disposed on a secondary side facing away from the medium and configured to seal the stationary component with respect to the rotatable component, and a sensor connected to a volume located between the first seal assembly and the second seal assembly and configured to detect a change of a moisture level in the volume. The stationary component further includes a bore located axially between a contact surface for the first seal assembly and a contact surface for the second seal assembly, and the volume is connected to a pressure tank by the bore.

Abstract: A composite elastomeric flexible element has an elastomer layer between rigid members. When subjected to loads, and as time goes by, the elastomer layer will undergo damage in the form of micro-voids and polymer chain scission. The time it takes the damage to reach a predetermined, but safe state is a known function of several parameters such as loading rate and load magnitude, time at load, temperature and frequency. The damage decreases the electrical permittivity of the elastomer and changes the electrical conductance of the elastomer if the elastomer is in the environment of an electrically conductive fluid or when the elastomer includes conductive filler. The health of the flexible element is monitored by measuring the electrical impedance of the elastomer layer, computing an indication of health from the electrical impedance and trend data for the elastomer layer, and reporting the indication of health to a human administrator.
