Abstract:
A face seal device for use with a rotating component rotating at a high rotational speed, comprising:a non-rotating face seal ring; a rotary face seal ring mounted in a loose fit for common rotation with the rotating component, wherein said rotary face seal ring comprises a sealing face which, in operation, is essentially radially aligned for cooperation with an opposite sealing face of said non-rotating face seal ring; and a mass-contributing means arranged to rotate in common with the rotating component and engaging a portion of said rotary face seal ring, wherein a center of gravity of said mass-contributing means is axially spaced by a spacing from a center of gravity of said rotary face seal ring, whereby a torque directed towards said non-rotating face seal ring is exerted to said rotary face seal ring in correspondence with centrifugal forces resulting due to said mass-contributing means and the spacing between the centers of gravity.
