ABSTRACT:
A wheel cylinder comprises a bore closed by two pistons which define a pressure chamber therebetween. The pressure chamber is divided into two compartments by a partition member placed in the bore and which comprises a passage communicating the two compartments. One of the compartments is connected to a source of pressurized fluid and a control valve is mounted in the passage for controlling the pressure in the other compartment as a function of the pressure in the one compartment, whereby the wheel cylinder acts as a proportioning valve.
