ABSTRACT:
A hand-held air blower device for directing a jet of air in a desired direction, including a barrel having a longitudinal axis and having a low pressure air inlet at an upstream end for admitting air at atmospheric pressure and an outlet at an opposite downstream end for the jet of air, the barrel having a throat, intermediate its ends, whose inner wall has a convex contour, and the barrel having a narrow high pressure air inlet slot, with an upstream and a downstream side wall in relation to the direction of air flow through the barrel immediately adjacent the throat on the low pressure air inlet side of the throat. The convex contour of the inner wall of the throat, along the longitudinal axis of the barrel between its ends, is disposed at a small acute angle to the downstream side wall of the high pressure air inlet slot, and changes progressively downstream to being disposed at a small acute angle to the longitudinal axis. A handle is connected to the barrel. A source of high pressure air is connected to the blower device. A manually-operable valve controls the supply of the high pressure air from the high pressure air source to the high pressure air inlet slot.
