Abstract: The present invention is a superior micro-abrasive blasting device (55) with a flow-control mechanism (65) and a flow-actuated discharge conduit seal (80). Flow-control is achieved through the deformation of discharge conduit (10) to control the opening of discharge conduit (10). The flow-control mechanism (65) provides for the continuous pressurization of the mixing chamber (23) to yield instantaneous flow start-up response and instantaneous flow shut-off response.

Abstract: The present invention is a superior micro abrasive blasting device (55) with an integral flow control mechanism. Flow control is achieved through the displacement of discharge conduit (10) to control the distance between discharge conduit inlet (12) and mixing chamber second end wall (30). The flow control mechanism provides for the continuous pressurization of the mixing chamber (23) to yield instantaneous flow start-up response and instantaneous flow shut-off response.

The flow control mechanism provides for the continuous pressurization of the mixing chamber (23) to yield instantaneous flow start-up response and instantaneous flow shut-off response. A method is provided for maintaining discharge conduit outlet (67) stationary with respect to target material (40) while discharge conduit inlet (12) is displaced. The method utilizes the deflection properties of discharge conduit (10) to provide the necessary compliance so the discharge conduit inlet (12) can be displaced while the discharge conduit outlet (12) remains stationary.

Abstract: The present invention is a superior micro abrasive blasting device (55) with an integral sealed reservoir (22) that converts into a mixing chamber (23). When not in use, the micro abrasive blasting device (55) forms a sealed reservoir (22) that protects the stored particulate matter (20) from contamination and spillage. When the device is setup for use, the sealed reservoir (22) transforms into an operational mixing chamber (23). A method is provided for easily unsealing reservoir (22) and turning it into the mixing chamber (23) in a single motion. In the preferred embodiment, a compliant closure cap (30) is displaced along the container side wall (15) in the direction of the container end wall (17) . The displacement causes the gas-delivery conduit (25) disposed within the reservoir (22) to protrude through the compliant closure cap (30) and to form a gas-receiving port (35).
