Abstract
The valve piston is charged with powdered fuel, such as coal, which is initially metered into a fuel transfer channel during a downward stroke of a dosing and ejecting member and then blown via compressed air through the valve piston into the combustion chamber upon completion of the downward stroke of the dosing and ejecting member. A slider is used to allow metering of the fuel without interference from the compressed air. After the fuel charge is metered, the slider moves transversely of the transfer channel to permit entry of the compressed air so that the charge can be blown into the combustion chamber via the valve piston.
