ABSTRACT:
A sealing arrangement is disclosed for sealing a stationary member to a rotatable member and comprises a pair of rubbing seals mounted on one of the rotatable and stationary members in rubbing engagement with the other of the members. The rubbing seals are relatively closely spaced to form a sealant space therebetween extending radially from the rotatable member to the stationary member and circumferentially and continuously about the rotatable member. The stationary member has a sealant passage extending therethrough in communication with the sealant space. An arrangement is provided for injecting fluid sealant through the sealant passage and into the sealant space so that the sealant space is completely filled with sealant to form a continuous sealing band of fluid sealant extending circumferentially about the rotatable member.
