ABSTRACT:
In a mixed medium brake system for a motor vehicle, there is provided a hydro-pneumatic brake cylinder device in a common housing having a compact configuration that is realized by designing the hydraulic piston in the form of a cylindrical plunger having a hollow cavity in the end adjacent the pneumatic piston, whereby engagement of the pneumatic piston push rod with the plunger is at a location thereof forward of the end adjacent the pneumatic piston, thus minimizing the distance required between the pneumatic piston and the hydraulic piston formed by the plunger. Such an arrangement also reduces the binding action of the cylindrical plunger in its guide bore for improved operation, while accommodating pivotal motion of said pneumatic piston.
