Abstract

Improvements introduced into the system to vary the transmission ratio, in the directions, especially of motor vehicles with power steering; -; and with hydrostatic transmission of the steering force to the steering wheels, consisting of a servo pump, a control pump connected to the steering wheel of the vehicle, a control valve fitted behind the latter and at least two servo motors acting on the wheels that they must be directed, characterized in that the control valve is provided with a control valve that serves as a diverter device, to which two reversing valves are added in such a way that in a first change position of the two control valves Inversion coupled to each other the pressure element transported by the servo pump is led with one part through the control valve as well as the metering pump and with another part through the control valve, diverting the control valve and the control pump to the servomotors, while in a second change position of the two reversing valves, the entire pressure transported by the servo pump through the control valve and the control pump to the servo motors, diverting the control valve.
