Title: Viscous fluid coupling device
Inventor: NAKAMURA TAKATSUGU
IPC: F01P7/08
Filed: 1990-11-09
Abstract: PURPOSE:To prevent drop of the torque transmission efficiency by closing the passage within a rotor by means of the rotor centrifugal force when the shaft rotational frequency is high, thereby reducing the torque transmission quantity between transmission components in the working chamber. CONSTITUTION:When the input rotational frequency to a shaft 11 is low, a valve body 32 of a rotor 16 opens a third passage 19, so that the flow of a viscous fluid in the X arrow direction is permitted. Accordingly, a first transmission component 16a and a second transmission component 16b both work. On the other hand, when the input rotational frequency to the shaft 11 is high, the valve body 32 closes the third passage 19, so that the flow of the viscous fluid is stopped as indicated by an arrow Y. Accordingly, only the first transmission member 16a works, thereby cutting the unnecessary torque transmission quantity in the high speed rotation region, lowering the fan noise, reducing the engine drive loss horsepower and lowering the viscous fluid temperature.
