The atomizer has a conduit for distributing liquid from a single supply inlet to a plurality of feed holes spaced apart from one another. The cross-sectional area of the distribution conduit decreases at increasing distances from the inlet, thus promoting even distribution of liquid among the multiple feed holes at both high and low flow rates. The rate of decrease of cross-sectional area preferably is made inversely proportional to the viscosity of the liquid. In its preferred form, the atomizer utilizes a converging-diverging nozzle with a cavity resonator to generate sonic pressure waves to atomize the liquid. The distribution conduit of decreasing cross-sectional area is formed by using eccentric cylinders, one inside the other, with the cylinders being farthest apart near the liquid inlet, and nearest together 180.degree. from the liquid inlet.
An ultrasonic water jet having first and second housing members. The first housing member includes an interior exponentially shaped duct and a plurality of water inlets equiangularly displaced and circumferentially disposed about the central axis of the exponentially shaped duct for cleansing a face of the ceramic disk transducer clamped between the first housing member and an O-ring seated in the second housing member.
A shower device attachable by suction cups to a wall, such as adjacent a bath tub; the device including a panel supporting a row of adjustable shower heads to each of which water is supplied that is selectively mixed with diluted soap from a soap dispenser mounted on the panel, a pulsator being selectively used to pulsate the sprayed water, and a flexible hose from the device for connection to a water supply faucet valve.
A liquid atomizing method and apparatus in which atomization is achieved through acceleration of a primary air flow injected through an upstream throat (58t) into a diverging passage (61) between the upstream throat (58t) and a downstream throat (68) to create shock waves in the air flow which impact a wall surface adjacent and generally opposed to a confined liquid column to create sonic and/or ultrasonic vibrations which are directed into the confined liquid column to cause the column to fracture into tiny droplets of a narrow size range below 50 microns in diameter. One or more auxiliary air flows may be injected through other upstream throats (60t) into the diverging passage (61) in the flow direction of the primary air flow downstream of the first throat to supply energy to the boundary layer and to enhance acceleration of the primary jet through entrainment. The effective cross-sectional flow area of the downstream throat (68) is between 1.25 and 1.50 times the combined effective cross-sectional flow area of the upstream throats (58t, 60t).
A spray generator has a gas duct (1, 6, 10, 14, 16, 21) from which issues a stream of gas in various configurations according to the shape of the delivery end. Liquid is directed by nozzles (3, 11) or other means (13, 18, 22) transversely into the gas stream, although it may have a directional component going with that stream and/or a component to generate swirl. The relative speeds and amounts of gas and liquid cause the liquid to break up into droplets (9, 24) which form discrete clusters (5, 8) in a compact spray pattern. Secondary gas streams (17, 23) can be applied further to shape the spray pattern.
