摘要： A split seal ring having end faces that self-align in both the axial and radial directions is prepared by forming an opposing first pair of angled grooves extending from an inner edge partway across the seal ring inner diameter, and a second pair of angled grooves extending from the inner edge partway across the seal ring rear surface. In embodiments, corresponding grooves meet to form V-shapes. Additional grooves can extend from the outer edge partway across the inner diameter. Corresponding grooves extending from the outer and inner edges on the inner diameter can terminate at locations that are offset radially and/or angularly. By applying an outward force, the seal ring is split at the groove locations into split ring sections having mating end faces. The resulting end face geometry is sufficiently complex to cause both radial and axial realignment as the seal ring halves are mated together.

摘要： A thermal actuator for a rotating shaft shutdown seal that has a piston with a portion of its axial length enclosed within a chamber shell with a material that expands upon a rise in temperature. The portion of the actual length of the piston within the chamber has at least two different diameters with the larger diameter leading in the direction of travel of the piston. Upon a rise in temperature, expansion of the material surrounding the piston within the chamber creates a force on the piston in the desired direction of travel.

摘要： Compression between two blocks (5, 6) forming a dynamic seal (13) between a rotor (2) and a stator (1) is applied by an inflatable seal (7) located in a groove. When blocks (5 and 6) must be cuttable, in other words divided into two parts to be assembled around the shaft (2), the originally linear seal (7) is wound in the groove and its ends are in contact with each other. It applies a uniform compression around the circumference and its placement does not require major disassembly of the equipment.

摘要： An intershaft seal for inner and outer coaxial shafts which rotate relative to each other. The seal is located in an annular space between the shafts and maintains an axial pressure differential between a fluid pressure on the first side of the seal and a fluid pressure on the other, second side of the seal. The seal comprises a sealing ring which is coaxial with the shafts and which forms a sealing contact with the outer shaft to maintain the pressure differential.
