| 20090127798 | Sealing apparatus having circulating channel for wire cutting machine - The present invention discloses a sealing apparatus having a circulating channel for a wire cutting machine, and the sealing apparatus includes a channel at the position of a lower arm in the fluid tank for injecting a liquid, a sealing O-ring installed at the sealing apparatus for preventing a leak of liquid, such that a circulating channel is formed around the periphery of the lower arm. The liquid is injected through an injecting inlet into the circulating channel such that the centrifugal force produced by the whirling flow can wash away the debrises attached on the lower arm, and discharge the debrises from a discharge opening to the outside. | 05-21-2009 |
| 20100096810 | SEALING SYSTEMS - A sealing system includes two fittings, a compliant member, and a spring. The first fitting has two ends, a first cavity, and a first channel. The first channel extends from the first end to the first cavity, which is formed in the second end radially inwardly from an outer surface of the first fitting. The second fitting is disposed in the first cavity and has two ends, a second cavity, and a second channel. The first end is disposed in the first cavity, the second cavity is formed in the first end of the second fitting, and the second channel extends from the second cavity to the second end. The compliant member is disposed in the second cavity. The spring is disposed in the second cavity against the compliant member. | 04-22-2010 |
| 20110140369 | 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. | 06-16-2011 |
| 20110156361 | SPRINGS AND METHODS OF FORMING SAME - A seal includes a polymeric jacket defining a seal surface and an inner cavity extending within the polymeric jacket along a length of the polymeric jacket. The seal further includes a spring extending within the inner cavity and including a plurality of laser cut spring elements. The seal can be disposed between a static component and a rotatable component. | 06-30-2011 |

| 20130026714 | Sealing Device - A sealing device in which a good lubricating oil film is formed along the entire circumference of a sliding surface. The sealing device ( | 01-31-2013 |
| 20140117628 | SEALING MEMBER OF DISK TYPE PARKING BRAKE - A sealing member for sealing a disk type parking brake may include a cap member having a hole in the center and pressed in a rear end portion of the caliper at which the shaft may be mounted, and an elastic member which may be mounted between the cap member and the rear end portion of the caliper and extended to the outside of the caliper for sealing the shaft and the brake lever, wherein the elastic member includes a slope portion which may be positioned between the cap member and the rear end portion of the caliper and may be slantly protruding out in radial direction, and one end portion of the cap member may be contacted with the outer surface of the slope portion by being bended out in radial direction. | 05-01-2014 |
| 20150008648 | SEALING DEVICE - In a sealing device installed to an installation groove which is provided in an outer peripheral surface of one member among two members relatively moving, and sealing between the two members by coming into close contact with the other member which is positioned in an outer peripheral side of the installation groove and one side wall of the installation groove, the sealing device has a seal ring, a support ring having a pressing surface which comes into contact with an inner peripheral corner portion the seal ring, and a spring means which presses the support ring and the seal ring. A collapsing margin in relation to the taper surface shaped pressing surface in the support ring is normally set in an inner peripheral corner portion in the seal ring. According to the sealing device, it is possible to improve pressure resistance and sealing performance. | 01-08-2015 |
| 20150048574 | SEALING DEVICE AND SEALING STRUCTURE - The sealing device includes: an outer peripheral ring | 02-19-2015 |
| 20150115544 | Rotary Seal with Anti-Slip Energizing O-Ring - A seal assembly includes an annular static sealing member disposed within an annular channel in a housing or shaft. An annular dynamic sealing member is disposed coaxially within or about the static member and has a circumferential sealing surface engageable with the shaft or housing. An annular biasing member is disposed radially between the static and dynamic sealing members and is configured to bias the dynamic sealing member radially to maintain engagement of the sealing surface and the shaft or housing. The static member is configured to prevent relative angular displacement between the static and biasing members and the dynamic member is configured to prevent relative angular displacement between the dynamic and biasing members. As such, the dynamic sealing member, the biasing member and the static sealing member angularly displace within the channel as a single unit when torque above a particular magnitude is applied to the dynamic sealing member. | 04-30-2015 |
| 20160033044 | SEAL DEVICE - There is provided a seal device having a seal ring structure assemblable without lowering the assembling efficiency of CVT, and free from oil leakage when an oil pump is not operated with an engine stopped, namely when oil pressure is not applied to the seal ring, which comprises a combined seal ring comprising an endless resin ring having an outer peripheral surface in slidable contact with an inner peripheral surface of an outer member, and a coil expander pushing the resin ring toward its outer peripheral surface and side surface, the coil expander being arranged in a corner recess portion of the resin ring between its pressure-receiving side surface and its inner peripheral surface, and an inner peripheral side of the combined seal ring being separate from a bottom of the seal ring groove. | 02-04-2016 |
