Abstract:
A dynamic seal system for a planetary rotor engine having a casing, at least two end walls each having an inner surface and a plurality of internal rotors, each rotor having rotor ends and a rotor face, each said rotor mounted on a rotor shaft having a centerline and positioned to cause contact of adjoining rotor faces and thereby define a combustion chamber, further defining a gap between said rotor end and said casing, said dynamic seal system comprising:at least one surface depression substantially forming an annulus covering and disposed on at least one of the group comprising the casing surface and the rotor end, said depression substantially changing the velocity of a fluid passing through the gap such that pressure and vacuum pulses passing between the ends of the rotor and the corresponding casing end walls of the machine during operation of the machine are attenuated;means for adjustably positioning each centerline of said rotor shafts radially with respect to one another such that adjacent rotor faces are in sliding contact with one another at all times during operation of the engine, whereby leakage from the combustion chamber of the machine between said rotor faces in precluded;means for sealing the rotor shaft including a plurality of annular fulcrum elements, a plurality of pivoting arms annularly disposed about each said annular fulcrum elements, and means for flexibly encasing said annular fulcrum elements and said respective pivoting arms, wherein said means for sealing the rotor shaft respectively surrounds each rotor shaft, disposed between the casing and each rotor face.
