Abstract

Improvements in hydraulic transmission systems characterized by comprising a mechanically driven displacement type pump with means to connect its outlet passage to the entrance passage of the main hydraulic motor, also of the type of displacement that drives a driven element; the output passage of the motor is connected to the input passage of the pump and this or the motor or both are of variable capacity to allow the variation of the transmission ratio between the pump and the motor; and comprises a hydraulic booster whose piston or analogous active element is ready to actuate the mechanism by means of which the capacity of the pump and motor is varied while the servomotor pilot valve is ready to be operated by a control element and means connected with the working fluid pressure of the main motor, prepared to connect the output step of the hydraulic servomotor to a source of fluid under pressure automatically, provided that the working pressure exceeds a certain value.
