ABSTRACT:
A fluid clutch comprising a driving section, a rotational shaft rotated by the driving section, a driving disk driven rotationally by the rotational shaft, a casing containing the disk and rotatable around the rotational shaft as a center, a partitioning member disposed in the casing for dividing the inside of the casing into a torque transmission chamber and an oil reservoir in which an oil is supplied from the oil reservoir to the torque transmission chamber thereby transmitting the torque from the driving disk to the casing, wherein the fluid clutch comprises a pump mechanism that rotates due to a difference between the number of rotations of the rotational shaft and the number of rotation of the casing, a first flow channel for sucking the oil in the torque transmission chamber by the pump mechanism and a second flow channel for sending the oil pressurized by the pump mechanism into the oil reservoir, a valve member for opening and closing a supply aperture formed in the partitioning member for causing the oil in the oil reservoir chamber to flow into the torque transmission chamber, and a solenoid type actuator for operating the valve member.
