Abstract

The apparatus for metered delivery of powder has a vessel (1), beneath which is permanently installed a metering device (2), in the bottom section of which a pipe (3) for transport gas is provided in the form of an ejector. The pipe (3) is connected via a low-pressure pipe (6) to a chamber (4) which is situated on a vertical side wall of the metering device (2). The chamber (4) is closed at the end by a membrane (5) which firmly seals the outlet orifice of the vessel (1). Depending on the vacuum which is generated by the ejector in the pipe (3) for the transport gas and the delivery of the powder and which acts on the membrane (5) in the chamber (4) via the low-pressure pipe (6), the membrane (5) accordingly lifts off from the delivery orifice, as a result of which a metered powder delivery can be achieved. The powder passing into the ejector is delivered by the transport gas in the pipe (3). <IMAGE>
