Abstract
A soot collector, e.g., for collection of soot from the exhaust gases of a diesel-powered internal combustion engine, having a fluid metering device which makes possible exact metering of a specified quantity of a soot remover by a controlled flow of compressed air onto the filter medium of the soot collector for regeneration of the filter medium, and which works reliably and can be manufactured economically. The fluid metering device of the soot collector includes a reservoir, a metering tank arranged in the vicinity of the reservoir bottom, a line which bypasses the metering tank, and a fluid inlet opening in the metering tank which can be closed in response to a flow of compressed air through the metering tank.
