  • Angled radial lip seal assembly
    Patent number: 11391375
    Abstract: A seal assembly for sealing an annular space between a shaft and a housing includes an annular case coupleable with the housing or the shaft and an annular seal member having a sealing surface centered about a centerline. In certain constructions, a coupler is configured to connect the seal member with the case or to connect the case with the housing such that the seal member is positioned with the sealing surface centerline intersecting or skew with respect to a central axis when the seal assembly is installed about the shaft. In other constructions, the seal member has an angled end providing the angled sealing surface. Thereby, the centerline of the sealing surface defines an angle to the central axis having a value of at least one degree, and the sealing surface engages the shaft outer surface to define an elliptical sealing interface extending circumferentially about the central axis.

  • Next gen riffle seal
    Patent number: 11384653
    Abstract: A seal assembly includes at least one primary seal, whose ends terminate in a modified air duct that is housed in a precision bore located at the ends of the primary seal slots. The air duct functions to seal the primary seal slot ends. A slot milled in the face of the air duct allows the primary seal to pass through and terminate centrally in the air duct bore. Minimal interference between the bore and air duct prevents cooling air from escaping the bore, completing the seal. Proper specification of the length of the primary seal in conjunction with precise location of the air duct bores allows for ample thermal expansion without loss of sealing. Axial clearance between the mating bores and air duct ends provides allowance for build tolerance, thermal expansion and movements between mating nozzles including movements between corresponding vane manifold portions.
