ABSTRACT:
A viscous fluid coupling device is comprised of (1) an input member, (2) a rotor secured to the input member, (3) an output member having therein an inner space and mounted rotatably on the input member, (4) a partition plate, for dividing the inner space into an operating chamber and a reservoir chamber for storing therein an amount of viscous fluid, secured to the output member and having a passage for establishing a fluid communication therebetween, (5) a thermal response valve, for opening and closing the passage, provided on the output member, (6) a labyrinth, for transmitting the rotation torque from the input member to the output member via the viscous fluid, provided therebetween so as to be positioned in the operating chamber, (7) a pump device, for returning the viscous fluid to the reservoir chamber, formed between an outer periphery of the rotor and an inner surface of the output member, and (8) a bypass device, for the direct supply of the viscous fluid supplied from the reservoir chamber to the pump device upon high speed rotation of input member, positioned in the rotor in parallel with the labyrinth.
