277638000 | Extrusion preventing (i.e., antiextrusion) structure | 7 |
20080224421 | ASSEMBLY HAVING GASKET RESISTANT TO SIDE LOADING BY PRESSURIZED FLUID - An assembly that includes first and second housing members, a gasket and a plurality of bolts that exert a clamp force to clamp the gasket between the first and second housing members. The gasket includes a plurality of tab members that engage the interior of one or both of the first and second housing members. The gasket tabs can resist a force exerted by a pressurized fluid within one or both of the first and second housing members. A method for assembling and operating an article is also provided. | 09-18-2008 |
20100025942 | SEALING SYSTEM AND SEAL COMPONENT FOR A DISPLAY ASSEMBLY OF A PORTABLE DEVICE - A display assembly for a portable terminal for inhibiting the penetration of foreign matter from an exterior environment into the interior of the portable terminal. The display assembly includes a display for mounting in an open faced compartment enclosed by a bottom/top cover plate, the display having a bottom surface, a plurality of side surfaces, and a top surface for interaction with a user of the portable terminal. The compartment of the enclosure of the display assembly has an interior bottom/top surface and a plurality of interior side surfaces. A resilient seal component of the display assembly is positioned between the display and the compartment, the seal component including a body including a base portion connected to a top portion by a plurality of side portions for defining an interior channel for engaging the sides of the display, once received therein. A top portion of the seal component is adapted for overlapping a portion of the top surface of the display and the base portion for overlapping at least a portion of the bottom surface of the display. The body has the exterior surface for positioning adjacent to the interior surfaces of the compartment and the interior surface of the channel for positioning adjacent to the top surface and the bottom surface and the plurality of side surfaces of the display. The seal body has a first sealing rib positioned on either the exterior surface or the interior surface of the seal body, the first sealing rib being integral, for example, with the seal body and projecting from the respective exterior or interior surface. The first sealing rib when positioned on the interior surface is for inhibiting the penetration of the foreign matter between the display and the first sealing rib and the first sealing rib when positioned on the exterior surface is for inhibiting the penetration of the foreign matter between the compartment and the first sealing rib. | 02-04-2010 |
20100219592 | Sealing Array for High Temperature Applications - A sealing array for positioning in an annular space between tubular members to provide a seal therebetween. The sealing array includes a pair of oppositely disposed backup rings, each defining a primary outer seal member of the sealing array. A pair of rigid cap rings is disposed between the backup rings. Each cap ring has a substantially planar surface and an oppositely disposed surface that engages one of the backup rings to energize the backup rings upon the application of sufficient pressure. The cap rings are sized to form controlled extrusion gaps with both tubular members. An energizing element is disposed between the planar surfaces of the cap rings. The energizing element engages a planar surface of at least one of the cap rings and seals the extrusion gaps associated with the engaged cap ring upon the application of sufficient pressure. | 09-02-2010 |
20120261890 | PRESSURE SEAL - A pressure seal assembly for sealing a bonnet assembly that is removably received by an access port defined by a body portion of a high pressure control device. The seal assembly inhibits leakage between the body portion and the bonnet assembly and includes an annular graphite gasket having a tapered portion defining an angled surface engageable with a complementally-formed surface on the bonnet assembly. A first anti-extrusion ring is urged into sealing engagement with a surface defined by the access port. A pair of inner and outer anti-extrusion rings are urged into sealing contact with an access port surface and bonnet surface. The bonnet assembly includes a reduced diameter section which defines a seal assembly receiving cavity. The anti-extrusion rings include overlapped ends, which allow expansion and contraction while maintaining overlapping contact. Camming surfaces may include retaining segments which maintain the inner and outer extrusion rings in an assembled relation. | 10-18-2012 |
20130038028 | Seal and Associated Sealing Arrangement - A seal including a tubular carrier body ( | 02-14-2013 |
20130069321 | SEALING STRUCTURE - A sealing structure enables easy fitting of an endless backup ring and includes: tank main body having filling chamber body with filling chamber and mouthpiece portion formed in cylindrical shape integrally with filling chamber body; valve body having insertion portion inserted in mouthpiece portion; O-ring provided between mouthpiece portion and insertion portion; and first backup ring endless and disposed on one side of O-ring to restrict movement of O-ring, wherein annular housing groove is formed on inner circumferential surface of mouthpiece portion such as to be recessed outward with respect to radial direction in order to house O-ring and first backup ring, wherein mouthpiece portion is provided with first cylindrical portion integral with filling chamber body and second cylindrical portion attachable/detachable along axial direction to/from first cylindrical portion, and wherein housing groove is divided along axial direction to face outward when second cylindrical portion detaches from first cylindrical portion. | 03-21-2013 |
20140306408 | SEALING DEVICE FOR A COLLET CHUCK - A sealing device for a collet chuck has a tensioning nut, a sealing washer, a main sealing ring and a pressure space. The sealing washer is mounted in the tensioning nut and has a main ring groove, an abutting surface, a liquid-inlet surface, and a liquid inlet. The liquid inlet is formed between an imaginary surface extending from the abutting surface and the liquid-inlet surface. The main sealing ring is mounted and positioned in the main ring groove. The main sealing ring protrudes out of and abuts the main ring groove. The pressure space is formed between a rear side of the main sealing ring and the main ring groove. Therefore, a coolant poured into the sealing device can pressure the main sealing ring to deform the main sealing ring, such that the main sealing ring can tightly abut a tool shank. | 10-16-2014 |
