FIELD: transport engineering. SUBSTANCE: pneumatic distributor relates to pneumatic devices designed for changing direction of compressed air flows in pneumatic lines of pneumatic drives depending on control action. Two kinematically intercoupled pneumatic devices are built into valve pneumatic distributor, namely, device for setting fixed manual doubler drive rod in initial position, and device with valve opening pneumatic control chamber operating from external source (pneumatic signal) and with electric signal fixed manual doubler drive. Pneumatic signal is formed either from control pushbutton in driver's cab or from control pushbuttons on outer side of vehicle body. Said devices provide prompt and emergency opening of vehicle door flaps both manually from passenger compartment, or and remotely, from external source, with holding doors open. EFFECT: improved reliability. 4 dwg
