261066000 | Liquid inlet | 20 |
20090174087 | One piece liquid injection spray cylinder/nozzle - A one piece spray cylinder/nozzle, with integrally machined nozzles, for use on a high pressure and temperature, probe style, variable nozzle, gas and steam coolers. The nozzle holes can be made by deep drilling techniques such as laser, gun drilling and others methods that produce a hole, with a diameter to depth ratio of less than 1:3. No separately machined nozzles are used. On the outlet end of the nozzle (on the outside of the cylinder only), there are surface machining treatments to produce small, controllable liquid droplets that vaporize quickly into the gas or vapor stream. The spray cylinder bore can be coated, lined or hard faced to resist the ware of the piston rings sliding in it without adding stresses to the spray cylinder body at braze and weld joints. The flow and patterns and valve characteristics can be modified. | 07-09-2009 |
20110140290 | CHARGE FORMING DEVICE AND VALVE FOR THE SAME - One implementation of a carburetor may have a fuel bowl in which a supply of fuel is received for delivery from the carburetor to an engine, and may include a valve rotatably supported by a body, an operating lever coupled to the valve, and a stopper. The operating lever may move the valve between a running position in which fuel flows through the valve in a first direction and into the fuel bowl, a stop position in which fuel does not flow either into or out of the fuel bowl through the valve, and a drainage position in which fuel flows in a second direction out of the fuel bowl through the valve. The stopper may be moveable between a non-permissive state in which the operating lever is not permitted to move in a first direction from one of the running position and the stop position to the other position, and a permissive state in which the operating lever is allowed to move in the first direction. | 06-16-2011 |

20130154133 | CARBURETOR FLOAT AND METHOD OF MANUFACTURING SAME - A method of making a carburetor float by first creating a homogeneous mixture of gas and polymer in a plastic injection machine. The gas/polymer mixture is injected into a tool having a mold cavity. A moveable portion of the mold cavity allows the gas/polymer mixture to expand in that area thus forming a foamed portion of the finished float. The portion of the mold that is stationary does not allow the gas/polymer mixture to foam and thus forms a portion of the finished float with a higher density that the foamed portion. The result is a float made of the homogeneous mixture with two differing densities in two different portion of the float. | 06-20-2013 |
