摘要： A seal (100) includes a seal body (102) disposed about a seal axis (104) and configured to be mounted to a first component (60) at a second axial end (110) of the seal body (102). The seal body (102) includes an interior surface defining a seal gland (116) circumferentially extending about the seal axis (104). A packing (120) is disposed within the seal gland (116). A retaining ring (132) is in communication with a second radial side of the packing (120) and is disposed within the seal gland (116). A plurality of exciter springs (140) are mounted to a second radial side of the retaining ring (132). The plurality of exciter springs (140) are biased against the interior surface of the seal body (102) and are configured to center the packing (120) within the seal body (102). The packing (120) is configured to receive a second component (52) and form a seal interface between the packing (120) and the second component (52). The seal body (102) is configured to form a portion of a passage (106).

摘要： Provided is a seal ring (11) in which a ring body (11) configured to be mounted in a mounting groove (22) provided in one of two members, for example, a rotary shaft (21) and a housing (31), that are configured to be assembled together so as to be relatively displaceable with respect to each other, is provided with a contact portion (12) that comes in contact with the other of the two members, and a cut portion (14) separating the ring body (11) at one position on the circumference of the ring body (11). In order to eliminate undercorrection of shape that occurs at a portion in the vicinity of the cut portion (14), thereby reducing the size of a gap that is formed between the seal ring (11) and the mating component when the seal ring (11) is mounted, a thinned structure (15) is provided only at a portion in the vicinity of the cut portion (14) in an outer surface of the ring body (11) other than the contact portion (12).
