    摘要： A seal includes a primary seal (10) arranged to provide a fluid tight seal between a shaft (17) and housing (12) and an auxiliary sealing device (25) having a running clearance when the primary seal (10) is operating normally but impeding flow of fluid upon failure of the primary seal (10). A drain (26) is provided to the space (27) between the primary seal (10) and auxiliary sealing device (25) and an annular element (30) is mounted upon shaft (17), intermediate of the primary seal (10) and auxiliary sealing device (25), for rotation with the shaft (17). The annular element (30) is provided with vanes (31) which induce flow of fluid past the auxiliary sealing device (25) into the space (27) and out through the drain (26).

    摘要： A gas tight seal comprises a retaining means (5) adapted to be mounted on a partition (l) to surround a rotary component (l0) where it penetrates the partition (l). A pair of annular floating members (3) are located in axially spaced apart relationship by said retaining means (5). Sealing means (9; 20) are provided between the inner periphery of the floating members (3) and the rotary component (l0), these sealing means (9; 20) being arranged to make sealing engagement with the rotary component (l0) when liquid under pressure is introduced into the space (8) between the floating members (3).

    摘要： A seal assembly for providing a seal between a pair of relatively rotatable components has; a first seal ring (30) mounted in sealing relationship, non- rotatably and for limited axial movement on a first of the components; a second seal (50) ring mounted in axially aligned relationship to the first seal ring, said second seal ring being mounted in sealing relationship, non-rotatably and for limited axial movement on a second of the components; first resilient means associated with the second seal ring urging it axially towards the first seal ring,- second resilient means (40) acting on the first seal ring urging it away from the second seal ring to separate the first and second seal rings; and a centrifugal actuator (20) associated with the first seal ring, said centrifugal actuator comprising a radially extending chamber (38) between the first seal ring and the component associated therewith, said chamber being connected to a source of fluid, whereby when the components rotate relative to one another with fluid in the chamber, centrifugal pressurisation of the fluid in the chamber will apply an axial load to the first seal ring urging it axially against the second resilient means and a sealing face of the first seal ring into sealing engagement with a sealing face of the second seal ring.

    摘要： A seal assembly for providing a seal between a pair of components has a sealing ring made of flexible plastics material and a backup ring (70) made of resiliently flexible plastics material being located coaxially of the sealing ring on the side thereof remote from the limbs, the backup ring abutting a f rusto-conical surface (62) of a base of the sealing ring, said frusto-conical surface engaging a corresponding frusto-conical surface (74) of the backup ring, to apply a radial load to the inner periphery of the backup ring urging it towards the outer periphery of the inner component, when an axial load is applied to the sealing ring by exposure of the sealing ring to pressure from the side of the sealing ring to which the limbs extend, a projection (72) on the backup ring engaging an inner periphery of an axially extending annular recess (80) in the outer component, to locate and support the reinforcing ring radially.
