FIELD: machine building.SUBSTANCE: invention relates to the field of railway transport, in particular to devices for control of cars retarder on the sorting rolls. Device for control of pneumatic drive of car retarder with pneumatic cylinders of braking of right and left wheels, connected by right and left pneumatic lines with air collector under pressure, comprises a brake valve installed in each pneumatic line, the inlet of which is connected to the air collector, and the outlet – to the air-decelerator air cylinder, controlled from the piston pneumatic cylinder, and releasing brake valve, the inlet of which is connected to the section of the pneumatic line between the outlet of the brake valve and the pneumatic cylinder of the car retarder, and the output is connected to atmosphere. Braking and releasing pneumatic valves are straight-flow. First and the second pneumatic valves with electropneumatic control of braking and releasing valves. Electronic control unit of the first and the second pneumatic valves has a user interface, pressure sensors connected to the control chambers of brake and release valves, the electric part of which is connected to the electronic control unit.EFFECT: lower working pressure in cylinders and higher accuracy of its adjustment.1 cl, 2 dwg
