FIELD: machine building.
SUBSTANCE: invention relates to feeder for supply of liquid additive from tank into device for treatment of waste gas. Invention relates to feeder (1) for liquid additive feed from tank (2) in device (3) for treatment of waste gas at least having channel (4) for supply to common volume (20) and pump (5) located in channel (4) of supply. Channel (4) is downstream of feed pump (5) in direction (6) for supply of flexible part (7) of wall, which outer side (29) located opposite channel (4) of supply, rests against stop (9), when pressure in channel (4) of supply is in a predetermined range (11) of working pressure. On outer side (29) there is a spring element (8), which is made for deformation of flexible parts (7) of wall so that total volume (20) of channel (4) of supply is reduced in size when pressure in channel (4) for supply is lower than threshold pressure (31). Present invention also relates to a method of compensation of ice formation in feeding device.
EFFECT: technical result is increased reliability.
