FIELD: transport engineering. SUBSTANCE: proposed pneumatic distributor is designed for vehicle door drive pneumatic systems. Pneumatic distributor has housing, two opening and closing valves with four valveseat shutoff members, electropneumatic control valve, electric signal manual doubling drive installed in cylindrical bore of housing in form of stepped axially movable plunger sealed over outer surface and holding bushing enclosing the plunger, and system of working channels and pneumatic lines interconnecting the valves and slave mechanism. Electric signal manual doubling drive is furnished with control chamber formed by walls of guide of housing cylindrical bore and corresponding end faces of sealed plunger and its enclosing bushing. Radial channel communicates chamber with external source of control pneumatic signal, and bushing enclosing the plunger is sealed over outer and inner surfaces. Plunger is installed in guide cylindrical bores of housing and bushing over outer surfaces with guaranteed ring clearances over outer surfaces. EFFECT: improved reliability. 4 dwg
