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 present disclosure generally relates to a nozzle or tip (202; 1002) for a fluid delivery system (100), and more specifically, but not by limitation, to a nozzle (202;1002) for a texture sprayer (102). In one exemplary embodiment, a texture spraying system (100) is provided and includes a spraying device (102), an air source (106) configured to provide pressurized air to the spraying device (102), and a texture material source (104) configured to provide texture material to the spraying device (102). The system (100) also includes a nozzle (202; 1002) mounted proximate an output of the spraying device (102). The nozzle (202;1002) receives a flow of air and a flow of texture material. The nozzle (202; 1002) includes a pin (230; 1030) positioned in the airflow and is configured to produce a spray pattern that is substantially rectangular.
Abstract:
A method for disinfection of a contaminated enclosed facility with microaerosol containing free radicals produced from an electrochemically- activated solution. In one embodiment of the invention the aerosol is produced from the EAS and air mixture at the air: EAS ratio (1-10):1 (by mass) with the droplets of ≤10 μm. This method is preferably performed by the atomization of the mixture with a vortex ejector nozzle with subsequent separation of coarsely dispersed particles.
Abstract:
A pump dispenser (20) has a pump arrangement for mounting to a reservoir (not shown) for holding a liquid to be dispensed. The pump arrangement includes a liquid pump chamber (43) for pumping liquid from the reservoir, an air pump chamber (50) for pumping air and a common actuator (21) to simultaneously actuate the liquid pump and the air pump. An outlet fluid passageway arrangement (31, 33, 34, 35, and 52) fluidly connects the liquid pump chamber and the air pump chamber with an outlet (36). The dispenser has an outlet valve arrangement (26, 26, 53) for controlling release of liquid from the liquid pump chamber and air from the air pump chamber during a dispensing cycle. The dispenser is configured such that the ratio of air to liquid dispensed varies over the course of each dispensing cycle. Preferably, the ratio of air to liquid is lower during a main dispensing phase, when the pressure of the liquid is at its highest, than during at least one of an initial phase and an end phase during which the pressure of the liquid is lower than during the main phase.
Abstract:
A pump dispenser (20) for mounting to a liquid container comprises a cylindrical type pump arrangement of the type having a mounting member (25) for mounting the dispenser to the container, a generally cylindrical body (23) located within the mounting member for projection into the container, a turret collar (24) for positioning the body within the mounting member, an elongate piston (22) movably mounted within the body, a seal member (26) operative between the piston and an inner surface of the body to define a liquid pump chamber (43) within the body and an actuator (21) mounted to, or operatively connected with, the piston. The dispenser is adapted to provide an air pump chamber (50) at least partially within the actuator and an outlet passageway arrangement of the dispenser includes at least one constricted orifice (36) through which liquid from the liquid pump chamber is passed.
Abstract:
A decontaminating system (100) comprising a decontaminant reservoir (152), a transport fluid source (160) and a mist generating apparatus (10). The mist generating apparatus (10) has a longitudinal axis and comprises a first fluid passage (38) having a first fluid inlet (18) in fluid communication with the decontaminant reservoir (152) and a first fluid outlet (84), and a second fluid passage (90) having a second fluid inlet (20) in fluid communication with the transport fluid source (160) and a second fluid outlet (94). The first passage (38) surrounds the second fluid passage (90) and the first and second outlets (84, 94) are oriented relative to one another such that they have an angle of incidence between (5) and (30) degrees. The second fluid passage (90) includesa throat portion (92) located between the second fluid inlet (20) and the second fluid outlet (94), the throat portion (92) having a smaller cross sectional area than that of either the second fluid inlet (20) or second fluid outlet (94).
Abstract:
Die Erfindung betrifft eine Vielloch- oder Bündeldüse (45, 43, 49) mit mehreren Austrittsöffnungen (56, 58) für zu zerstäubendes Fluid (1). Erfindungsgemäß sind die Mittellängsachsen (44) von wenigstens zwei der Austrittsöffnungen (56) windschief zueinander ausgerichtet, wobei sich ein Abstand zwischen den Mittellängsachsen (44) dieser Austrittsöffnungen (56) und der Mittellängsachse (16) der Düse in Ausströmrichtung gesehen zunächst verringert, ohne die Mittellängsachse zu schneiden, und nach Durchlaufen eines minimalen Abstandes wieder vergrößert.
Abstract:
A spray device is provided that includes a body portion having a fluid passageway therein. A spray nozzle is affixed to the body portion. The spray nozzle includes a discharge orifice for directing fluid from the fluid passageway in the body portion in a predetermined spray pattern. A valve needle is supported in the body portion and spray nozzle for movement between an open position for permitting fluid discharge through the discharge orifice and a closed position for preventing fluid discharge through the discharge orifice. A control piston assembly is provided for controlling movement of the valve needle. The control piston assembly is movably supported in the body portion and is non-mechanically coupled to the valve needle by magnetic attraction.
