Abstract

Improvements in power steering mechanisms for motor vehicles, of the class that comprise a double-acting actuator cylinder formed in the steering box itself, with a piston associated with the steering mechanisms and linked with a steering spindle connected to the steering wheel, by means of mechanisms that transform the rotation of this spindle into piston displacement, this forming two work chambers that can be connected selectively and alternatively with an arrival and return of pressurized actuating fluid by means of a valve device that reacts to the movement of the flywheel, essentially characterized Due to the fact that the spindle that carries the coupling means with the actuator piston is developed in a tubular form and inside it a rotary axis is mounted that protrudes to the outside for its connection with the steering wheel and is connected with said spindle to through elastic means that tend to keep both the elements in a relative position of rest and centered, the facing surfaces of said spindle and shaft being provided with combinations of complementary cavities in which passages communicating with the two chambers of the cylinder and with the arrival and return of the actuating fluid, and arranged with way they constitute the valve device.
