| 20130213510 | HIGH MASS FLOW CHECK VALVE ASPIRATOR - The embodiments disclosed herein provide a check valve aspirator including a venturi pipe having a converging section with a converging inlet and a converging outlet, and a diverging section with a diverging inlet and a diverging outlet. The converging outlet is in fluid communication with the diverging inlet. An outlet channel is in fluid communication with the venturi pipe and has an outlet port. A ratio of a diameter of the converging section outlet to a diameter of the outlet port is less than 0.4. | 08-22-2013 |
| 20130306181 | Multistaged Lean Prevaporizing Premixing Fuel Injector - A multistaged lean prevaporizing premixing fuel injector apparatus is provided. The fuel injector may be utilized with a turbogenerator. Preheated combustion air from the turbogenerator's recuperator may be utilized by the fuel injector to prevaporize liquid fuel. The injector may provide for premixing of multiple fuel streams and include multiple stages with a flow distributor plate separating adjacent stages. The injector may include multiple stages, with a pilot tube located in a final stage splitting the fuel stream into a premixed pilot stream and a premixed final fuel and air mixture stream. | 11-21-2013 |
| 20140360607 | ASPIRATORS FOR PRODUCING VACUUM USING THE VENTURI EFFECT - Aspirators are disclosed herein that include a body defining a Venturi gap between an outlet end of a converging motive section and an inlet end of a diverging discharge section and have a suction port in fluid communication with the Venturi gap. The converging motive section defines a circular-shaped motive inlet and defines an elliptical- or polygonal-shaped motive outlet, and the diverging discharge section defines an elliptical- or polygonal-shaped discharge inlet. In one embodiment, the converging motive section defines an inner passageway that transitions as a hyperbolic function from the circular-shaped motive inlet to the elliptical- or polygonal-shaped motive outlet and the elliptical- or polygonal-shaped motive outlet has an area that is less than the area of the circular-shaped motive inlet. | 12-11-2014 |

| 20100006168 | JET-MIXING METHOD AND JET-MIXING APPARATUS - The invention provides a jet-mixing method for casting a pile of predetermined diameter by thrusting or feeding into the ground a rod provided at its lower end with a first jet nozzle section for jetting ground improvement medium and a second jet nozzle section for jetting reactant in substantially the same direction as the jet direction of the first jet nozzle section, and provided above the first and second jet nozzle sections with a third jet nozzle section for mixing and jetting compressed air and water in a direction opposite the jet direction of the first and second jet nozzle sections, jetting compressed air and water within a predetermined range while simultaneously rotating and upwardly extracting the rod from the ground, thereby jet-cutting a ground improvement region into a cylindrical shape, discharging mud generated by the cutting operation to the ground surface through a bored hole, and jetting the reactant from the second jet nozzle section and jetting the ground improvement medium from the first jet nozzle section. A jet-mixing apparatus for implementing the method is also provided. | 01-14-2010 |
| 137892000 | With selectively operated flow control means in inlet | 4 |
| 20090255601 | FLUIDIC CONDUIT WITH REPEATED DISTURBANCE OF LAMINAR FLOW - A fluidic device, the fluidic device comprising a planar fluidic conduit for conducting a fluid, wherein the fluidic conduit has a plurality of fluidic disturbance features located along at least a section of the fluidic conduit for disturbing a laminar flow of the fluid along the section. | 10-15-2009 |
| 20110139284 | DILUTED-FLUID DISPENSING DEVICE WITH PRESSURE-COMPENSATING PASSIVE VALVE - Herein is disclosed a diluted-fluid dispensing device that operates on the venturi principle to mix a concentrate with a diluent. A pressure-compensating passive valve is provided in a fluid passage of the device through which diluent flows, in order to enhance the precision of the dilution over a range of pressure and/or flowrate at which diluent may be supplied to the device. The passive valve may be placed in proximity to the diluent inlet of the device. The passive valve may be a self-actuating valve. | 06-16-2011 |
| 20150007900 | VENTURI MIXER - A venturi mixer has first and second fluid input sections, an output section and a throat. The first fluid input section has first and second ends, and a decreasing cross sectional area from the first end to the second end. The throat is disposed at the second end of the first fluid input section and has a plurality of orifices. The output section has a first end connected with the throat and a second end, and an increasing cross sectional area from the first end to the second end. The second fluid input section has an inlet and a housing connected to the inlet and enclosing the orifices of the throat. | 01-08-2015 |
| 137893000 | Flow control means is located in aspirated fluid inlet | 1 |
| 20100139798 | In-flow liquid dispensing system - An in-flow liquid dispensing system has a connection point in a pipe between a water source and an outlet to which a liquid canister may be attached. At the connection point the pipe has parallel water paths, one path bypassing the liquid canister and the other including the liquid canister to inject the liquid from the canister into the water flow. One or more valves control the water flow through the respective paths to adjust the ratio of water to liquid from the canister, which may be either one path or the other or a combination of water flow through both paths. | 06-10-2010 |
| 137895000 | With condition responsive valve | 1 |
| 20120234420 | Steam Supply System and Check Valve for Use Therein - A steam supply passage incorporates a pressure reducing valve and the passage further incorporates a steam ejector downstream of the pressure reducing valve. A suction portion of the steam ejector is connected to a re-evaporation tank for re-evaporating steam condensate via a suction passage. Passage steam of the pressure reducing valve is used as a driving steam for the steam ejector. In operation, re-evaporated steam within the re-evaporation tank is suctioned by the steam ejector to be mixed with the passage steam. The suction passage incorporates a check valve for preventing reverse flow of steam to the re-evaporation tank. | 09-20-2012 |
