ABSTRACT:
A fluid coupling interposed between an induction motor and a load has an impeller and a turbine together defining a working chamber connected via radially inward and radially outward passages with a delay chamber on the impeller side of a corotating housing. The two sets of passages are selectively blockable by shutters that are controlled by an evaluator, inserted in a space between the motor and load shafts, which also accommodates a power supply consisting of one or more batteries. The evaluator responds to several sensors, measuring such parameters as motor torque, load speed and acceleration, to drain or refill the working chamber.
