Abstract

The invention relates to a compact seal packing (10), ensuring dynamic sealing between a rotary shaft and a stationary body, in particular a stationary enclosure. In particular, the seal packing (10) comprises a compression spring (16) bearing against a transmission element (18) to transmit the forces of the spring to a friction ring (12) and press it against a counter-ring (14). The compression spring (16) is bearing against a first radial flange (181) of the transmission element (18), a second flange (182) of the transmission element (18) being located partially facing a radial surface (122) of the friction ring distant from the counter-ring (14) and a cylindrical wall (180) of the transmission element (18) being located partially facing the cylindrical outer surface (124) of the friction ring (12).

Abstract

The invention relates to a compact seal (10) providing dynamic sealing between a rotating shaft and a stationary body, in particular a stationary chamber. The seal (10) comprises in particular a compression spring (16) supported against a transmission element (18) for transmitting the forces of the spring to a friction ring (12) and pressing same against a counter-ring (14). The compression spring (16) is supported against a first radial rim (181) of the transmission element (18), a second rim (182) of the transmission element (18) being located partly opposite a radial surface (122) of the friction ring remote from the counter-ring (14) and a cylindrical wall (180) of the transmission element (18) being located partly opposite the cylindrical outer surface (124) of the friction ring (12).
