Abstract:
A dispensing device (10) capable of dispensing both frothed and non- frothed liquids, the dispensing device having in order a fluid transport medium (20) defining a flow channel (25), a trigger controlled liquid flow regulator (30) defining a flow channel (35) through which fluid may flow when the trigger (37) is in one position but not when the trigger is in another position, a flow block (50) defining a flow channel (55) in fluid communication with a gas channel (65) and removably attached to the flow regulator, a flow restriction orifice (40) between the flow block and the flow regulator (30), a mixing block (70) defining a flow channel (75) containing mixing elements and optionally stabilization (80) and extension blocks each containing a flow channel (85) wherein each flow channel is in fluid communication with one another.
Abstract:
A substantially planar assembly for depositing material. The assembly comprises plates which, when assembled, define at least one aerosol channel, a sheath gas plenum, and a nozzle. These components are preferably anisotropic, and preferably rectangular. The aerosol channel may be divided further to improve uniformity of aerosol flow.

Abstract:
An atomizer(5) for atomizing a liquid has a gas chamber (15) adapted to be connected to a supply of gas and a liquid chamber (30) adapted to be connected to a source of liquid. A mixing tube (38) extends from the gas chamber (15) in a downstream direction, and atomizing gas flows through the tube (38) at subsonic speed. A liquid conduit (32) fluidly connects the liquid chamber (30) with the mixing tube (38) so that liquid from the conduit (32) can be entrained in the gas flow for discharging a mixture of gas and partially atomized liquid from the tube (38). The mixture then flows through an exit gap (65) to the exterior of the housing (10). The exit gap (65) has several successive shear steps (45) which contact the mixture as it flows through the gap (65) to thereby substantially fully atomize the liquid as it is being discharged from the atomizer (5). The atomizer (5) permits variations in the liquid flow rate and therewith variations in the rate at which atomized liquid is discharged from the atomizer (5) by modulating the rate at which the liquid is entrained in the gas streams while maintaining the gas stream flow rate and pressure substantially constant.
Abstract:
Apparatus (11) for cleansing living tissue includes a source (41) of a sterile liquid which is maintained substantially at atmospheric pressure, a source of pressurized gas, a fluid delivery head(314) having a fluid outlet (354), a gas conduit (376) extending between a gas inlet (360) connected to the source of pressurized gas, a gas outlet (370) located in the fluid delivery head, a liquid conduit (386) extending between a liquid inlet arranged in fluid flow communication with the liquid source, and a liquid outlet located in the fluid delivery head and in fluid flow communication with the gas outlet, and a valve (372) mounted, and operatively associated with the gas conduit, permitting gas flow through the gas outlet.
Abstract:
The invention relates to a new atomizing device with improved droplet formation. Smaller droplets are formed with increased micronized volume throughput, wherein high volumes of air are fed to a liquid sprayed from a liquid nozzle (2). High volume ratios result in mean free path between droplets being conveyed so as to minimize collisions and to prevent aggregation of the droplet.
Abstract:
The invention suggests a spray element 20, in particular for die spraying devices 10, comprising supply means 42 for liquid working medium and, optionally, supply means 50 for control air, an atomizing device 78/80b connected with supply means 42 for working medium and a switch valve 62 controlable in dependence of pressure, said switch valve 62 having a flexibly biassed valve body 68 for alternatively establishing or interrupting the connection between the supply means 42 for working medium and the atomizing device 78/80b. In spray element 20, the valve body 68 is designed as having inherent flexible bias.
Abstract:
A liquid spray device, comprising a container (1), a spray injection nozzle (2) for injecting oil spray into the container (1), a spray feeding path (5) for feeding oil spray in the container (1) to the outside of the container (1), oil (11) stored in the container (1), a gas exhaust port provided in the oil (11), and a submerged nozzle (4) for producing oil spray from the oil (11) by discharging gas into the oil (11), whereby the flow velocity of the oil spray in the spray feeding path can be increased and the amount of oil spray can be increased because an internal pressure of the container can be increased and an oil spray different from the oil spray from the spray injection nozzle can be produced.
