ABSTRACT:
An aspirator probe for a sand blasting apparatus and the like has a tube-within-a-tube construction wherein the inner tube is a delivery tube for supplying a mixture of sand and air to a delivery hose, and the outer tube is an air supply tube which surrounds the majority of the length of the delivery tube. The delivery tube has a lower end which may be coextensive with the lower end of the air supply tube, or recessed within the lower end region of the air supply tube. The delivery tube has an upper end portion which projects upwardly beyond the upper end of the air supply tube for connection with the delivery hose. A communicating formation provides a passage for communicating both tubes to introduce, as by aspiration, a flow of air into the flow of sand which is being drawn into and through the delivery tube. In one embodiment the communicating formation takes the form a non-coextensive arrangement of the lower ends of the delivery and air supply tubes. In another embodiment the communicating formation takes the form of a hole, slot or notch provided in a side wall portion of the delivery tube at a location in proximity to the lower end of the delivery tube. In still another embodiment the communicating formation takes the form of a notch or relief provided on the lower end of the delivery tube.
