может это какое-нидь усиливающее кольцо?
вот нашла краткое описание действия..
The (type of seal) sealing effect is achieved through an interference fit between the seal and the hardware, radial force from the O-ring energizer and system pressure. A true slipper seal, the (type of seal)relies on the O-ring energization to provide the sealing force at zero or low pressure. As the pressure increases, the (type of seal)is energized by hydraulic pressure and is forced against the sealing surface.

если еще что-нибудь найду,свистну..
