A sealing ring includes: an elastomeric sealing material which, when viewed in cross section, is substantially T-shaped; a support element extending in an axial direction; and a sealing lip extending in a radial direction. The sealing lip is elastically yielding and has a base which is formed as transitioning into the support element.

A cylinder boot for an axle of an industrial vehicle includes a cylinder boot body, a rod-side fixing portion, a cylinder-side fixing portion, and a detection portion. The cylinder boot covers a cylinder rod of a steering hydraulic cylinder. The cylinder boot body has a contractable portion that is contractable in response to a stroke of the cylinder rod. The rod-side fixing portion is disposed at one end portion of the cylinder boot body and fixed to a distal end portion of the cylinder rod. The cylinder-side fixing portion is disposed at the other end portion of the cylinder boot body and fixed to a cylinder body of the steering hydraulic cylinder. The detection portion is displaced in a direction in which the cylinder rod extends or contracts, and is detected by a detection sensor disposed on the beam axle.

An arrangement structure for a seal member includes: a first member having a first mating surface and provided with a groove portion; a second member having a second mating surface, and configured to move relatively to the first member; and an annular seal member fitted into the groove portion, providing sealing between the first member and the second member, and serving as a partition between an atmosphere-side space and a pressurized-side space. The seal member includes a plurality of first protruding portions protruding toward the second mating surface and aligned from the atmosphere-side space toward the pressurized-side space. The seal member has such a shape that, in a state of not being fitted into the groove portion, a protrusion height of the first protruding portion increases in stages from the first protruding portion arranged close to the pressurized-side space toward the first protruding portion arranged close to the atmosphere-side space.

Embodiments are directed to portable infusion devices, systems, and methods of using the same for dispensing materials. In some cases, the devices, systems and methods may be used for infusing a material such as medicament, e.g., insulin, into a body in need thereof.

In order to provide a sealing element which ensures a reliable seal and which can be produced easily and economically, it is proposed that a main body of the sealing element is formed from a partially fluorinated or fully fluorinated thermoplastic material which is injection-moldable.

Sealing device for a cartridge of a shock absorbing fork, provided with a screen of metallic material and with an elastomer coating, in turn comprising a radially outer portion which forms a static seal on a cartridge housing and at least one radially inner lip which makes a sliding contact on a moving element of the cartridge, wherein an additional lip forms a seal on a surface of the housing, thus sealing a cavity (V) of the elastomer coating.

A sealing system includes a housing with an interior chamber, where the interior chamber includes a mouth. The sealing system also includes a seal positioned adjacent to the mouth of the interior chamber and a plunger configured to move through the seal and into the interior chamber along a longitudinal axis of the sealing system. The plunger is configured to deform the seal from a first position to a second position, where in the first position, the seal has a first shape, and in the second position, the seal has a second shape, different from the first shape.

A sealing device that is adapted to be disposed between a reciprocating shaft and an inner peripheral surface of a shaft hole in which the reciprocating shaft is disposed, and that separates an oil side from an atmosphere side, includes an annular oil seal made of a resin, an oil-side rigid ring made of a metal, an elastomeric annular dust seal, and an atmospheric-side rigid ring made of a metal. The oil seal has an oil lip adapted to be in slidable contact with the reciprocating shaft and is formed of a resin having a glass transition temperature of 80 degrees Celsius or higher. The oil-side rigid ring is disposed around the oil seal and supports the oil seal. The dust seal is disposed on the atmosphere side of the oil seal and has a dust lip adapted to be in slidable contact with the reciprocating shaft.
