A seal is inserted into a space to be sealed. First and second end portions of the seal are engaged with first and second end surfaces of the space. The seal is compressed between the first and second end surfaces. The compression strains the seal. The strain includes the rotation of a cross-section of the seal so as to bias the seal into engagement with a surface forming one of an inboard surface and an outboard surface of the space.

Shaft sealing device and valve structure using the same

Номер: US20140013938A1
Автор: Chikashi Gomi, Kazuhiro Aoki, Tomoya Yamasaki
Принадлежит: Kitz Corp

A shaft sealing device switches a sealing state and an unsealing state of a fluid, with high sealing performance maintained, because no abrasion accompanies movement of a sealing material or a sealing member, enabling feeding a fluid at a predetermined flow rate, and adjusts the expanding rate of the sealing material with the quantity of an external electric signal and accordingly adjusts the contact face pressure to enable controlling the amount of leakage of the fluid highly precisely, so that it can be used for all applications. The shaft sealing device includes a shaft sealing body formed of a macromolecular material and made expansible or contractible, or deformable, through external electrostimuli applied to a shaft sealing portion disposed in a device body, and flow passages disposed in the shaft sealing portion for feeding the fluid leaked due to the expansion or contraction, or the deformation, of the shaft sealing body.

Номер: US20190032329A1
Автор: Gabriel Alexandre Nassar Junior, Giovanni de Andrade Baldi, Lincoln José Raad
Принадлежит: Embraer SA

Devices and methods are provided whereby a preformed elastomeric tubular seal profile may be installed into a gap defined between an adjacent pair of structural panels. The device may include a frame and opposed first and second compression rollers attached to the frame for rotational movement about respective rotational axes. The opposed first and second compression rollers define a nip space therebetween for the introduction of a preformed elastomeric tubular seal profile, whereby moving the tubular seal profile through the nip space causes the tubular seal profile to compress and thereby form a downstream compressed profile portion and an upstream uncompressed profile portion. The compressed profile portion may thus be inserted into a gap between adjacent structural panels and thereafter allowed to expand (e.g., by removal of a plug element from a distal end thereof) to thereby seal the gap.

A sealing assembly for mating two sections of an electrical device enclosure is disclosed. The enclosure includes a top and bottom joinable section. The sealing assembly includes a first sealing section disposed on the top joinable section that has both first and second upper projecting lip extensions. The second upper projecting lip extension has a height less than the first upper projecting lip extension and forms a channel therebetween. A second sealing section is disposed on the bottom joinable section, and includes a downward projecting lip extension and channel. The downward projecting lip extension is offset from the first section first upward projecting lip extension when the top and bottom joinable sections are joined. At that point the downward projecting lip extension engages within the channel of the first sealing section, and the second upper projecting lip extension of said first sealing section is engaged within the second sealing section channel. The second sealing section channel includes a compressible stubbed gasket having at least one locating stub corresponding to a receptacle in the top joinable section for positioning and holding the gasket within the top section during assembly.

A seal that enables an enclosure to be sealed and to keep an air pressure balance between an internal space within the enclosure and an external space outside the enclosure in such a way that water ingress into the enclosure is hindered in a predictable manner. This is accomplished by providing a seal having at least one small diameter tube with at least an inner surface being hydrophobic, oleophobic or omniphobic. The seal is mounted in the enclosure between the inner and outer space. To further avoid small particle contaminants to enter and go through the at least one small diameter tube, it is preferable to have a small diameter tube with curves and bends, and it will still allow an airflow through it if there is an air pressure imbalance.

An inclination angle (θ 1 ) formed with respect to a plane (PL1) perpendicular to an axis of a separator tube by a side surface of the sealing ring groove, which is located on an opening end side of the separator tube, is set to 8° or more. With this, a maximum tensile stress to be applied to an O-ring can be reduced to be smaller than a maximum tensile stress in a case of using a backup ring. As a result, the durability of the O-ring can be set equivalent to or enhanced to be higher than durability in the case of using the backup ring.

The softer ring acts as an extrusion barrier along the mandrel. On setting the softer ring protects a free end of an extrusion ring from contact with the sealing element by extending axially at least as far as the extrusion ring and preferably further. The sealing element being softer than the adjacent softer ring allows the extrusion ring to push the softer ring out past the end of the extrusion ring and allows the softer ring to fill a void space adjacent the free end of the extrusion ring and to the sealing element. Relative motion between the rings at the attachment location is prevented.

Systems and methods produce or provide a folded connection, sealed by means of an adhesive composition, between a first sheetlike element and a second sheetlike element. The systems and methods bond a second flange of the second sheetlike element with at least one layer of an adhesive composition to a first flange of the first sheetlike element, in such a way that an end of the second flange of the second sheetlike element is indented by a distance relative to an end of the first flange of the first sheetlike element. The systems and methods bead the first flange of the first sheetlike element around the second flange of the second sheetlike element and, after the beading, an adhesive-composition part is placed around an edge of the first flange of the first sheetlike element and bonded to a second surface of the first flange of the first sheetlike element.
