Abstract: A nozzle for use with a walk-behind blower includes a nozzle restriction due to a sloped upper wall of the nozzle body. The nozzle restriction increases the air velocity in the upper region of the nozzle and forces leaves and debris downward so that airflow through the lower region of the nozzle more effectively laterally displaces them. The configuration of the nozzle body may be adapted to accommodate a variety of engine outputs while utilizing a common design for a blower frame, impeller and shroud.

Abstract: An improved atomization jet assembly for aromatherapy essential oil diffuser wells. It does not loose the cap during handling. It uses the capillary of liquids principal to draw essential oils between the exterior of the jet FIG. 12 and the inner cap profile FIG. 7. The flow of liquid is stopped by a capillary break 40. The Ventura principal is then used to create a low pressure area between the top of the jet ball 44 and the inside radius of the cap 65. An air/oil mixture blows out of the cap orifice 66 with the aid of an air pump. The net result is increased availability of air molecules attaching to oil molecules and making them airborne and breathable.

Abstract: A fluid can be discontinuously atomized with an atomizer of the present invention. The atomizer can include a helical spring, disk spring or gas spring, acting as a pressure spring, as an energy storage device, a cylinder, piston, two ducts and two valves. Atomization can be initiated manually by triggering a locking mechanism. The energy storage device can be disposed outside a storage container for the fluid.
