Unitary, hand-held, portable, self-powered refillable mixed-media ejector tool

An integrated, portable, hand held, adjustable refillable, re-buildable, self powered tool for ejecting a stream of abrasive particulate, powdered, or liquid materials toward a target site comprising:

• a hollow materials reservoir chamber, accommodating a supply of abrasive granular particulate, powdered, or liquid materials connected by a special adapter to and supported by a mateable adapter attached to a pressurized container;
• a removable filler plug, removable from a chamfered seat in top of the hollow materials reservoir chamber, or any convenient location, for material refilling, wherein the improvement comprises the removable filler plug,
• a filler plug vent bore, incorporated into the removable filler plug, connecting ambient atmosphere to the inside of the material reservoir chamber, wherein the improvement consists of the vent bore in the removable filler plug,
• a hopper top with a downward protruding central collar supporting a central axial conduit whose internal bore directs the gas delivery tube attached to the trigger to alignment with propellants depressable plunger valve, by means of the linear alignment guides, wherein the improvement consists of the linear alignment guides,
• a gas delivery conduit in a trigger assembly to direct compressed gas to a replaceable air jet, wherein the improvement consists of the replaceability of the removable air jet,
• a gas delivery conduit in the trigger assembly to direct released gas to the air jet containing angular compression chambers exiting to a reduced diameter orifice for the further compression and adjustment of the compressed gas stream, wherein the improvement consists of the angular compression chambers contained in the air jet;
• an angular mixing aspiration chamber constructed inside the nozzle housing, for mixing of abrasive particulate, powdered, or liquid materials and gas,
• a replaceable ejector nozzle housing containing the advanced mixing aspiration chamber, wherein the improvement consists of the replaceability of the nozzle housing assembly,
• a material delivery conduit tube connecting the advanced mixing aspiration chamber with the bottom of the material reservoir chamber, through a flow control adjustment valve assembly,
• a replaceable cylindrical tube with a conical end, made of a suitable wear resistant material, such as steel or rubber, lining the nozzles exit conduit, positioned to produce enhanced negative pressure promoting aspiration of materials from the materials reservoir chamber from the delivery conduit to the advanced mixing aspiration chamber, wherein the improvement consists of the replaceable cylindrical tube with a conical end to reduce wear of the nozzle exit conduit,
• a replaceable materials control valve connected and intersecting the material delivery conduit tube, wherein the improvement consists of the materials control valve,
• a flow control valve composed of a flow control shaft containing a bore, and a control valve lever to adjust the flow of materials from the materials reservoir chamber, wherein the improvement consists of the replaceable flow control valve and its components for the adjustment of the flow of materials,
• all of said components being combined in an integrated, symmetrically balanced, refillable, adjustable, parts replaceable, hand held portable assembly which can be seized, carried, adjusted, aimed and operated by the user in only one hand, wherein the improvements consist of the refillable, adjustable and parts replaceable nature of the invention.
