20100164184 | Encoder-equipped sealing device - An encoder-equipped sealing device, that is, a sealing device that has an encoder incorporated therein is disclosed, which comprises a combination of seal elements, each of which includes an annular metal core having a substantially L-shaped cross section and including a cylindrical portion and a flange portion provided on one end of the cylindrical portion and extending in a direction perpendicular to a direction in which the cylindrical portion extends. One seal element, of the two seal elements, and the other seal element are combined such that a space defined by the cylindrical portion and flange portion of the one seal element, and a space defined by the cylindrical portion and flange portion of the other seal element, face opposite each other, wherein the one seal element further includes an elastic seal portion provided on the flange portion and arranged in the space defined by the cylindrical portion and flange portion, and the other seal element further includes a magnet-based encoder provided on the flange portion. The one seal element further includes a projecting portion on an end of the cylindrical portion on a side on which the flange portion is located and extending beyond a side of the flange portion opposite a side on which the seal portion is located and in a direction in which the cylindrical portion extends. | 07-01-2010 |
20100237566 | SEAL ASSEMBLIES FOR MOVABLE AND STATIC SHAFTS - Seal assemblies for sealing around a moveable shaft, such as rotary or reciprocating, or static, are described. The seal assemblies prevent the passage of lubricant or fluid from a relatively high pressure area on a first side of the seal to a relatively low pressure area on a second side of the seal. In some embodiments, these seals are energized by energizers, such as circular springs or canted springs, to keep the seal in contact with the moveable shaft. The seals have primary and secondary seals. The secondary seal provides initial moderate sealing against abrasive particles or contaminants to reduce the exposure and wear of the primary seal. | 09-23-2010 |
20100295254 | Sealing device - The invention provides a sealing device in which adhesion of an elastic member used for the sealing device is controlled, and a coefficient of friction against a member sliding against the sealing device is reduced. | 11-25-2010 |
20130300069 | METAL COIL PROPELLER SHAFT SEAL FOR DEEP DIVE VESSEL - A propeller shaft seal for sealing a propeller shaft in a stern tube, comprising a bi-direction rotational sealing body being fitted within the stern tube and wrapped around the propeller shaft in its axial direction; wherein the bi-direction rotational sealing body comprising two metallic helical coils stacking together in a way that is mirroring each other; wherein the first and second metallic helical coils being constructed from helically coiled metal tapes of varying widths linked together and coiled into rings and with the rings tightly bounded; and wherein at any one time during operation, a rotational direction of the propeller shaft is same as coiling direction of one of the two metallic helical coils but opposite to that of the other of the two metallic helical coils. | 11-14-2013 |
20140125014 | HIGH TEMPERATURE SEAL ASSEMBLY - A seal assembly includes a semi-tubular sealing element defining a longitudinal axis, and a retainer configured to retain the sealing element. The sealing element has a longitudinal center portion and first and second longitudinal side portions, an array of resilient arcuate fingers extending from the first longitudinal side portion and curving partially around the longitudinal axis, and a depressor portion extending from the second longitudinal side portion and having a free edge diametrically opposed to the center portion. The retainer defines a channel with an entrance opening, the channel being configured to receive the sealing element in a position in which the depressor portion extends outside of the entrance opening in position to bear a load, the channel being defined by a pair of opposed side walls configured to resiliently capture the sealing element. | 05-08-2014 |
20140333033 | PROTECTIVE DEVICE FOR PISTON ROD-CYLINDER APPARATUS - A debris wiping device ( | 11-13-2014 |
20140361494 | SYSTEM, METHOD AND APPARATUS FOR SPRING-ENERGIZED DYNAMIC SEALING ASSEMBLY - A seal assembly is disclosed. The seal comprises a metal spring bonded to an elastomer body that is coupled to a polymer ring. The spring may comprise a cantilevered, overlapped metal strip. The elastomer and polymer mechanically interlock with radial members. The elastomer has contacting surfaces configured in outward extending radii to enhance forward edge loading and oil removal from the dynamic surface. In hydraulic service, the seal prevents the egress of hydraulic fluid and ingress of foreign particles. | 12-11-2014 |
20150097344 | Sealing Device - A sealing device with a lip edge portion | 04-09-2015 |
20160116065 | PRESSURE RELEASED WIPER ASSEMBLY FOR A SEALING ARRANGEMENT - A pressure released wiper assembly is arranged to fit into a ring-shaped groove in a cylinder or at a piston rod. The pressure released wiper with a V- or U-shaped cross section includes an opening in the axial direction to a potential contaminated side of the wiper assembly, a ring shaped base portion, a ring disk shaped rear portion, a lip portion, one or more through openings from the opening through the rear portion to a gap formed between the cylinder wall and the rod or piston outside the ring-shaped groove, and one or more filters covering at least the one or more through openings to the potential contaminated side of the wiper assembly in the filter holder. | 04-28-2016 |
