Abrégé

A ring fastener comprising a discontinuous band having first and second axial faces on opposite sides, a first end with a first end face and a groove extending from the first end face and opening to the first axial face; a second end with a second end face and a tongue projecting from the second end face; wherein the groove is u-shaped and the second axial face defines the base of the groove, and the tongue is dimensioned to fit in the groove; such that, when the tongue is received in the groove, the first end is located relative to the second end and a continuous ring is formed. A method of assembling the ring fastener into a circumferential groove in a component comprises the steps of feeding the ring fastener into the groove so that the ends are adjacent to each other; distorting the second end axially out of the plane of the groove; bringing the ends towards each other until the tongue overlies the groove; and inserting the tongue into the groove so that the ends are within groove.

A pressure activated non-contact seal for sealing against a rotating cylindrical surface between a high-pressure region and a low-pressure region comprises a seal member carrier spaced from the rotating surface defining a seal member chamber in fluid communication with the high-pressure region. A seal member is supported by the seal member carrier to be radially moveable. A secondary seal is mounted between the surface of the seal member and a surface of the seal member chamber to provide a pressure barrier around the seal member. The seal member comprises side walls extending towards the rotating surface to define a seal cavity. The ends of the side walls define non-contact seal surfaces. The seal member further comprises a bleed port extending between the seal cavity and the seal member chamber on the high-pressure side of the secondary seal. In use, high pressure in the seal member chamber urges the seal member towards the rotating surface until balanced by the pressure in the seal cavity to maintain the non-contact seal surfaces in a non-contact sealing relationship with the rotating surface. A seal assembly comprises multiple seals arranged circumferentially around the rotating surface.
