THE FACING BETWEEN THE ROTATING AND NONROTATING MEMBERS IS FORMED IN A LABYRINTH TO SUBSTANTIALLY INCREASE THE LENGTH OF THE PATH FOREIGN MATTER MUST TRAVEL BEFORE REACHING AN ELASTIC SEAL, ACTION OF THE SEAL GREATLY INHIBITS THE FURTHER TRAVEL OF ANY FOREIGN MATTER AND ALSO PREVENTS LEAKAGE OF THE LUBRICATING SUBSTANCE. A UNIQUE CONFIGURATION OF THE LABYRINTH EMPLOYS THE LAWS OF CENTRIFUGAL FORCE TO FURTHER PROTECT AGAINST THE ENTRANCE OF FOREIGN MATTER. THE CONFIGURATION OF THE ELASTIC SEAL SUBSTANTIALLY REDUCES FRICTION AND THEREBY INCREASES EFFCIENCY, RELAIBILITY, AND USEFULNESS OF UNIT CONTAINING THE INVENTIVE SEAL.
