  • Patent number: 5967526
    Abstract: A fluid control system for a rotating shaft which provides a seal to limit fluid leakage from around the shaft and which vacuums away any fluid leaking past the provided seal. The fluid control system may be installed around a rotating shaft such as a flywheel in a press. The fluid control system includes a housing which forms a clearance space with the rotating shaft in which fluid, such as oil being used to create or service the flywheel bearing, can be collected. A seal is provided between the rotating shaft and the housing to prevent fluid leakage from the clearance space. A vacuum mechanism positioned along a leakage path beyond the seal is provided with an air duct through which passes a vacuum induced air flow which vacuums away fluid leaked from the seal.
