Abstract: Various embodiments of the present disclosure are directed to packing rings. In one example embodiment, a packing ring is disclosed including first and second axial ring ends, at least three ring segments, and at least three relief openings. The at least three relief openings each have a first relief opening end opening into the radially inside inner circumferential surface of the ring segment. The first relief opening ends of two relief openings arranged adjacent to one another in the circumferential direction are spaced apart from one another at a relief opening circumferential distance. The first relief opening ends are closer in the axial direction to the first axial ring end than to the second axial ring end and are spaced apart at a relief opening axial distance from the first axial ring end, which is 4% to 20% of the axial ring width of the ring segment.

Abstract: A sealing member for relatively movable, e.g., rotating or reciprocating, members comprises a pair of annular rings each with a radially extending wall and an axially extending wall defining an annular seal gland. An elastic spring member compression-loaded in the seal biases the exterior surfaces against the bearing surfaces. The ring members are preferably of TEFLON, or like polytetrafluoroethylene plastic, RYTON, polyphenylene sulfide, or a soft elastic metal capable of being compressed by the spring member against the walls of the surface being sealed. The spring is a rubber or elastomeric O-ring or the like. Other spring members, such as a Belleville spring assembly or the like, may be used. This seal is characterized by its operation at elevated temperatures, i.e., up, to 1000.degree. F.

Abstract: A metallic sealing ring assembly (10) for sealing an annulus between metallic surfaces of concentric tubular members. The assembly comprises a central metallic sealing ring (11) having flared upper and lower annular flanges (14, 15, 16, 17) at both its inner and outer peripheries. The sealing ring 11 is sandwiched between upper and lower adapter rings (12, 13) disposed concentric therewith and formed with bevelled annular edges (12a, 12b, 13a, 13b) which contact flared surfaces (14a, 15a, 16a, 17a) of the sealing ring flanges (14, 15, 16, 17) at a mating angle of five degrees. When axially compressed, the annular flanges of the metal sealing ring (11) are deflected radially and at their tips are deformed and extruded against the surfaces of the members (18, 19) defining the annulus to establish metal-to-metal seals therewith. The flanges are truncated at their free ends whereby initial engagement of the adapter rings (12, 13) with the metallic sealing ring (11) and annulus defining members (18, 19) is along the annular edges (14c-17c, 14d-17d) of the flange tips and the compression force is concentrated thereat. Axial loading is applied by holddown screws (50) with tips (51) in camming engagement with a camming surface (52) on the upper adapter ring (18).

Abstract: A ring-shaped sealing member is configured to effect a seal between a shaft arranged to rotate in one sense within a housing at a relatively high rate--typically in excess of 10,000 r.p.m. The sealing member fits closely around the shaft but is split to allow circumferential expansion thereof. At least one ramp surface facing the shaft is defined by the sealing member, the clearance between the shaft and ramp surface decreasing in the direction of normal rotation of the shaft.On rotation of the shaft at a high speed, air is carried round by the shaft within the gap of decreasing clearance between the shaft and ramp surface of the sealing member. The sealing member is expanded circumferentially thereby, and when the shaft rotates sufficiently quickly the air film carried round by the shaft lifts the sealing member completely clear of the shaft, the air film maintaining the seal between the shaft and the sealing member.
