ABSTRACT:
A device for introducing dosed or proportioned quantities of pulverized solid materials into a carrier gas stream is presented. The device comprises a housing which defines a flow chamber in the axial direction for the flow of pressurized fluid or carrier gas. The housing also has a side aperture therethrough. The side aperture is connected to a container holding pulverized materials. Coaxial inner and outer sleeves, at least one of which is capable of rotation, are located within the housing. The outer sleeve communicates with the aperture while the inner sleeve has an axial bore which provides a passage for the carrier gas. Upon rotation of a sleeve, slots provided on each sleeve will align and overlap with each other and with the aperture to define a variable sized passage between the container and axial bore whereby the pulverized material is delivered therethrough to the carrier gas stream. The rotating sleeve forms an integral portion of a drive shaft which is mounted coaxially in the housing by means of bearings, the drive shaft being movable in the axial direction.
