Abstract

Improvements in mechanical-pneumatic devices for driving the pneumatic brakes of vehicles in general, comprising a first group of cylinder-piston, with its mobile delivery attached to the braking organs and influenced by the pressure of the braking pneumatic device and by the action of elastic means, maintained in the loaded position by effect of said pressure, and a second group of cylinder-piston, influenced by the pressure controlled by the distributor of the braking device, whose mobile equipment is interposed between the mobile equipment, of the first group and the control means of the brakes, in order to drive the latter independent of said cylindrical piston-cylinder group, characterized in that the two cylinder-piston groups (28-30 and 30-68) are arranged and oriented so that form a telescopic or axial and concentric structure whose intermediate piston (30-34) joins the braking organs (38) by means of the piston i nternal (28) of said telescopic structure.
