  • Patent number: 10648567
    Abstract: The present disclosure relates generally to seal rings useful in rotating systems such as automobile transmissions, torque converters and automatic clutches. In one embodiment, the disclosure provides a seal ring in which the first end includes a platform in a radially inward portion of each lateral region thereof, and a vertically-extending blade in a radially outward portion of its central region; and the second end of the seal ring has two vertically extending fingers in a radially outward portion of each lateral region thereof, and a platform in a radially inward portion of its central region. When the ends are engaged, a portion of the extension of the blade is disposed radially directly over the central platform, a portion of each finger is disposed radially directly over a lateral platform, and the blade of the central region of the first end is disposed between the fingers.

  • Patent number: 9726292
    Abstract: A seal ring including a body having an inner surface, an outer surface, and a first side surface, and a tab extending from the body and adapted to prevent rotation of the seal ring relative to a component receiving the tab, wherein the tab extends radially inward beyond the inner surface and axially beyond the first side surface. In an embodiment, the seal ring further includes a relief portion adapted to accommodate a tab of an adjacent sealing ring such that the first side surface of a seal ring directly contacts the second side surface of the adjacent seal ring. In an embodiment, the tab locks the seal ring from rotational movement in relation to a first component.
