  • Control Of Velocity Or Acceleration (AREA)

Abstract

The speed of a fluid motor 1 is controlled according to the speed of a controllable electric motor 7. A differential gear 9 has two inputs 11 and 14 which are connected to rotating outputs 8 and 3 of the motors 7 and 1 respectively and has an output 16 which moves when the effective value of the ratio between the speeds of the outputs 8 and 3 deviates from a predetermined value. The output 16 operates a valve element 19 in such a way that the supply of fluid to the motor 1 is varied to oppose any deviation from the said predetermined value. <IMAGE>
