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. Drive of fixed manual doubler of electric signal made in form of axially movable rod with locking device consisting of shutoff member in form of ball contacting with conical ring groove of drive rod is built into valve pneumatic distributor. Such design makes it possible to open vehicle and hold it open at cessation of action of external load on rod of manual doubler drive. EFFECT: improved reliability and convenience in use. 3 dwg
