FIELD: machine building.
SUBSTANCE: invention relates to electropneumatic device (1) for controlling parking brake to control parking brake, comprising at least one brake cylinder with spring-loaded power accumulator, containing relay valve (18) with control chamber (42) and air outlet channel (56). According to the invention, it is provided that, depending on the position of piston (46), control chamber (42) through at least one second throttling element (65) and / or at least one third throttling element (66) can be connected to the air outlet channel (56).
EFFECT: improvement of electropneumatic control device of parking brake so that inexpensive and requiring low-structural space facilities at auxiliary braking, even at interruption of current supply, condition "parking" could be stably accepted.
