Abstract: 611,936. Hydro-kinetic couplings. PACKARD MOTOR CAR CO. April 16, 1946, Nos. 11737 and 11738. Convention dates, April 16, 1945, and Dec. 12, 1945. [Class 69 (ii)] In a hydraulic coupling comprising a driving rotor and a plurality of driven rotors, means is provided between the rotors to form inner and outer fluid - operating circuits, the inner circuit being confined to the driving rotor and one of the driven rotors and the outer circuit being formed by all of the rotors. The coupling has a driving rotor 4 fixed to the driving shaft 3, and driven rotors 5 and 6 connected to shafts 7 and 8 respectively for actuating a driven shaft. The fluid is circulated by the driving rotor 4 through the driven rotors 5 and 6 in series. The first driven rotor 5 has a torous member 20 which divides the operating fluid into two concentric circuits, the inner circuit A being confined to the driving rotor 4 and the driven.rotor 5, the outer circuit B being formed by all of the rotors. Shaft 7 is driven by the first driven rotor 5 to provide low speed to the driven shaft through suitable transmission means, and as the fluid pressure increases in the coupling the second driven rotor 6 becomes effective and takes over the drive through shaft 8. In modifications an inner torous member is provided on the driving rotor and the fluid flow is divided into three circuits.
