ASSEMBLY AND METHOD FOR MEASURING AND DISPENSING PRECISE AMOUNTS OF POWDERED MATERIAL

摘要

A measuring and dispensing assembly including a sealed housing defining a supply chamber with a measuring chamber immediately below the supply chamber. An outlet valve is disposed at the bottom of the measuring chamber and an inlet valve controls the flow of material from the supply chamber into the measuring chamber. The inlet valve has a cavity surrounding a control member which is movable into and out of the measuring chamber for changing the volume thereof. The inlet valve has a tubular portion extending upwardly and exteriorly of the housing for connection to an actuator. The control member for controlling the volume has a tubular section extending upwardly through the tubular portion of the inlet valve and exteriorly of the housing for connection to an adjustment means for varying the volume of the measuring chamber. The outlet valve has a stem extending upwardly through the tubular section of the control member exteriorly of the housing for connection to an actuator.
