Zusammenfassung:FIELD: mining. ^ SUBSTANCE: invention refers to equipment of automation of production processes in various fields of industry, may be used in mining during manufacturing of distribution devices for control of operating environment flow between sections and units of impact machines. Device contains body structure with installed in it slide-valve, partition and rod mounted in partition centre hole and interacting with slide-valve. In first version of its design device contains deflector of operating environment flow, outlet nozzle and control nozzle. Deflector is located on rod, on which spring is installed between partition and deflector. Outlet nozzle is connected to chamber of backward running of impact machine by means of outlet and inlet of slide-valve at its open position and by means of throttle - to source of operating environment, to which control nozzle is connected by control unit and mentioned throttle connected in sequence. In second version of its design device is provided with metre run, outlet nozzle and control nozzle. As a rod shaft is used on which the following is installed: slide-valve of swinging type, metre run and swinging spring located between partition and metrer run and operating to close slide-valve at no effect of control pulse Pcntr of operating environment pressure on metre run from control nozzle connected to source by means of control unit in sequence. ^ EFFECT: enhancement of device operation efficiency due to reduction of dynamic losses at its switch-over achieved by means of reduction of time required for slide-valve switch-over. ^ 5 cl, 2 dwg Изобретение относится к средствам автоматизации производственных процессов в различных отраслях промышленности, может применяться в горном деле при создании распредустройств для управления потоком рабочей среды между участками и агрегатами ударных машин. Устройство содержит корпус, установленные в нем золотник, перегородку и шток, смонтированный в центральном отверстии перегородки и взаимодействующий с золотником. По первому варианту оно содержит отражатель струи рабочей среды, выхлопное сопло и сопло управления. Отражатель расположен на штоке, на котором между перегородкой и отражателем установлена пружина. Выхлопное сопло соединено через выпускное и впускное отверстия золотника при его открытом положении с камерой обратного хода ударной машины и через дроссель с источником рабочей среды, с которым соединено сопло управления через последовательно соединенные блок управления и указа
