ABSTRACT:
A method of controlling the revolution of the drive shaft of an external combustion engine comprises shaping a control signal for a switching member and converting said signal to mechanical movement of an actuating member. The control signal is shaped in the form of symmetric, periodic sustained vibrations of variable sign, the time intervals of positive and negative values of said vibrations being of equal duration, and the frequency of said vibrations is set equal to a preset number of drive shaft revolutions. The variation of said movement corresponds in time to variation of the control signal, an instantaneous value of the control signal is varied in proportion to the variation of load on the drive shaft, and the actuating member movement is converted to revolution of the engine drive shaft.
