Disclosed is a railway braking system including a control device having a valve with a body having a cavity and a slide having an internal chamber, supply notches and drainage notches each having an overall passage cross-section for a pressure medium having a shape exhibiting an apex, and being movably mounted in the cavity, between a supply position where the supply notch is opposite a supply groove of the body, and a drainage position where the drainage notch is opposite a drainage groove of the body; the device being configured to allow a substantially stable control configuration, wherein the pressure value of the medium is limited, and wherein the slide is positioned in the cavity such that a control notch of the slide is opposite a control groove of the body while the supply and drainage notches are respectively at a distance from the supply and drainage grooves.

A hydrostatic transmission device of a mobile machine having &#x2014;at least one first motor and at least one second motor, &#x2014;at least one first dual motor and at least one second dual motor each having first and second elementary motor, &#x2014;the second elementary motor of the first dual motor is linked with the first motor by a serial duct, &#x2014;the second elementary motor of the second dual motor is linked with the second motor by a serial duct, &#x2014;each serial duct has a valve having an opening for passage of the fluid into the serial duct, said valve having a first position in which said opening has a maximum cross-section, and a second position in which said opening has a reduced cross-section, the movement of said valve between these two positions activated a control instruction generated when the machine is travelling on a slope.
