20090184476 | BUTTERFLY VALVE WITH A RIGID SEAL - A valve is disclosed and can include a valve body having a central bore for passage of fluid there through and a longitudinal axis. The valve can also include a seal installed within the valve body along the central bore. The seal can include a first seal member having an annular ring portion and a hub portion extending from the annular ring portion. The seal can also include a second seal member including an annular ring configured to engage a distal end of the hub portion and create a sealing engagement between the hub portion and the annular ring when a compressive force is applied to the first and the second seal members. | 07-23-2009 |
20160115804 | SEAL SUPPORT STRUCTURE - The present disclosure relates to sealing systems for gas turbine engines. In one embodiment, a seal support structure for a gas turbine engine includes a seal support configured to retain a circumferential seal and an engine support configured for mounting the seal support structure to a gas turbine engine mount. The engine support includes at least one channel configured to provide radial movement of the seal support structure and circumferential retention of the seal support. Another embodiment is directed to a sealing system including a circumferential seal and seal support structure configured to provide radial movement. | 04-28-2016 |
20160178061 | Rotary Seal Assembly For Accommodating Radial Deflection and Tilting | 06-23-2016 |
277504000 | Flexible connection between seal and another part | 3 |
20090102135 | Front cover of manual rotary pump - A front cover of a manual rotary pump includes a disk having a cavity eccentrically defined therein for airtightly receiving an oil seal. A through hole is defined in a bottom of the cavity to allow an input shaft of a rotor extending through the disk. The oil seal is airtightly sleeved on the input shaft for forming an airtight condition between the input shaft and the disk. The disk has at least two bores defined therein and longitudinally communicating with the cavity for operator to easily detach and replace the oil seal by using a tool extending through the at least two bores. A diameter of the through hole in the disk is slightly greater than that of the input shaft and the diameter difference between the through hole and the input shaft is ranged from 0.05 mm to 0.2 mm. | 04-23-2009 |

277505000 | Oscillates perpendicularly to axis of motion | 1 |
20120032405 | SEALING STRUCTURE FOR CONTINUOUSLY VARIABLE TRANSMISSION - A sealing structure for a continuously variable transmission, which seals a clearance between a movable sheave and a cylinder. The continuously variable transmission may change a groove width of each pulley of the cylinder by moving a corresponding movable sheave though supply and discharge of a hydraulic pressure to and from the cylinder. The sealing structure includes an outer peripheral side seal member that is ring-shaped and disposed in a ring-shaped groove formed in one of the movable sheave and the cylinder; and an inner peripheral side seal member that is more elastic than the outer peripheral side seal member, ring-shaped, and disposed in a layered manner in the ring-shaped groove on an inner peripheral side with respect to the outer peripheral side seal member. A side of the outer peripheral side seal member where it contacts the inner peripheral side seal member is chamfered. | 02-09-2012 |

20110198815 | SLUDGE AND SEDIMENT REMOVAL SYSTEM BY REMOTE ACCESS - A compound conduit containing inner and outer conduits with apertures in the former that are angled to direct jets of fluid in a rearward direction from the inner conduit into the annular space is used to draw sludge or undesirable material from a vessel without imposing a vacuum on the system. In conjunction with the compound conduit is a rotary tube seal that allows the conduit to be mounted to an orifice in a tank wall and pivoted or rotated over a range of angles. A tubing drive mechanism grasps the tubing at locations well removed from the distal end and causes the tubing to travel in the direction of the tubing axis. The gripping members in the mechanism engage the sides of the tubing and are capable of shifting position relative to each other to accommodate changes in the curvature of the tubing. | 08-18-2011 |
277508000 | Axially spring biased | 1 |
20120211945 | SEALING PACKING FOR A RECIPROCATING PISTON ROD OF A RECIPROCATING COMPRESSOR - A gas-proof sealing packing of a compressor includes a scraper recess on the crankcase-side end containing a gas-proof scraper ring, a sealing ring recess on the cylinder-side end containing a sealing ring arrangement (18), a barrier recess located axially between the scraper recess (15) and the sealing ring recess (17), and a drain line in the sealing packing that is connected with the space between the barrier recess and the scraper recess. | 08-23-2012 |
