  • Patent number: 9897310
    Abstract: An injector model for atomization of liquid fuel using a low pressure atomized gas. The model is focused to mix a volume of liquid fuel with a volume of corresponding atomizing gas to obtain a pressurized liquid fuel-gas mixture. This liquid-gas mixture is ejected through a discharge orifice into a lower combustion chamber pressure, as a result of which the liquid fuel breaks up into ligaments. The atomized gas emerges from the liquid fuel-gas mixture as a result of pressure jump and further enhances this break-up of liquid fuel into smaller droplets and promotes combustion of these droplets in the chamber.

  • Patent number: 7389941
    Abstract: The present invention includes a nozzle device and method for forming a composite fluid. The nozzle device generally comprises a nozzle portion connected to a main body. The main body includes an inner axial bore extending therethrough. An annular wall extends radially therefore and an annulus extends from an outer perimeter of the annular wall. The annulus and the annular wall define an annular chamber at least partially open to the atmosphere. A portal fluidly communicates the bore with the annular chamber. The nozzle portion includes a converging nose section also having an internal axial bore extending therethrough. An annular collar extends from the nose section and disposes at least partially within the annular chamber. A first tube for transporting a first fluid disposes within the axial bore of the main body and nose section, terminating at an exit port of the nozzle section.

  • Patent number: 7300001
    Abstract: A pump-dispensing atomizer includes a dispensing pump with a closure to engage with a container. The dispensing pump includes a pressing button with a booster chamber formed inside, a nozzle with one end extending from the pressing button and a probe formed with at least one section. An interior of the nozzle is formed with a guide chamber, and one end of the guide chamber is connected to the booster chamber. The guide chamber has at least one expanding sub-chamber. After the probe is disposed in the guide chamber, a boosting channel is formed between the expanding sub-chamber and the stepped section. Moreover, the pressure accumulator is mounted on the other end of the nozzle, which is formed with a spraying opening communicated to outer environment. As such, the pressure of liquid flowing in the nozzle will be increased effectively so that liquid is sprayed out with a higher pressure to increase the spraying speed of the liquid.

  • Patent number: 7264179
    Abstract: A nebulization system, which creates a uniform fog of tiny suspended liquid droplets, to lubricate the surfaces of MEMS devices. These droplets fall over the edge of a baffle and are then mixed with an umbrella-like sheet of N2 turbulation gas to generate a uniform cloud of droplets that fill a passivation chamber. The MEMS device is then positioned in this uniform cloud of lubricant droplets for a specified amount of time, thereby uniformly lubricating all the surfaces of the device. The system uses a laser monitoring approach to control the uniformity of the lubricant cloud by providing feedback to the system to control the flow of gases. The system also equalizes the pressure around the sample device seal to prevent gases from entering or exiting the chamber and thereby influencing the environment inside the chamber.

  • Patent number: 7108203
    Abstract: An internal mix spray nozzle assembly adapted for operation with lesser pressurized air requirements. The spray nozzle assembly includes a liquid passage for directing a liquid flow stream against an impingement pin, and an air guide is provided for forming an annular pressurized air passage about the liquid flow stream for striking and atomizing a laterally spreading dispersion of liquid from the impingement surface. For enhancing liquid atomization, the air guide defines a relatively narrow width air flow opening for substantially accelerating and increasing the pressure of the atomizing air stream, and the impingement pin is formed with a relatively large primary impinging surface and a parallel downstream secondary impingement surface that facilitates further liquid particle breakdown and prevents the accumulation of liquids about the bottom of the impingement pin.

  • Patent number: 7104336
    Abstract: The method of the invention comprises the steps of proportioning a foam concentrate into a non-flammable liquid to form a foam concentrate/liquid mixture and creating a flowing stream of the foam concentrate/liquid mixture. Nitrogen is introduced into the stream of the foam/liquid mixture to initiate the formation of a nitrogen expanded foam fire suppressant. In one embodiment the nitrogen is chilled below ambient temperature. The flowing stream carrying the initially nitrogen expanded foam is dispensed, which completes the full expansion of the nitrogen expanded foam fire suppressant, into the confined area involved in fire thereby to smother the fire and to substantially close off contact between combustible material involved in fire and the ambient atmosphere substantially reducing the danger of explosion or flash fires.
