Abstract
A portable air abrasion device has a dispensing chamber and a flow valve for controlling the flow rate from the dispensing chamber. The flow valve includes a fluid flow chamber for receiving granular materials exiting the dispensing chamber. The fluid flow chamber has a granular materials inlet port, a fluid flow inlet port for receiving the flow of a fluid to the fluid flow chamber and a fluidized granular material exit port for dispensing a fluidized mixture of the granular material away from the fluid flow chamber. The fluid flow chamber also has a flow regulator employing a lead screw to control the flow of fluidized granular material through the fluidized granular material exit port.
