Claims

[Scope of utility model registration request]

The hydraulic torque converter is filled with working fluid while being removed, and the turbine litchi is driven by the pump impeller through the filled working fluid. A flow control valve is provided in the working fluid supply path, and A fluid torque converter comprising means for controlling the operation of a flow rate control valve so that the amount of working fluid supplied is variable.
