| 20080272871 | ARMATURE AND SOLENOID ASSEMBLY - An armature for a solenoid assembly is disclosed. The armature includes a first portion, a second portion, and a fin. The first portion has a first axial length and a first diameter, and the first portion is configured for operative connection with a pole piece. The second portion has a second axial length and a second diameter that is larger than the first diameter. The fin extends radially from the second portion and has an axial length that is less than the axial length of the second portion. A solenoid assembly is also disclosed. | 11-06-2008 |
| 20090189104 | VALVE ASSEMBLY AND METHOD OF ASSEMBLY - A valve assembly is provided that has a valve body defining first and second valve seats and a fluid chamber between the valve seats. The valve assembly includes a first valve that has an extension portion and a plug portion. The plug portion is configured to be selectively seated at the first valve seat. The extension portion is configured to extend within the fluid chamber past the second valve seat when the plug portion is seated at the first valve seat. A second valve is configured to interfit with the extension portion to connect to the first valve for common movement therewith. The second valve is configured to be selectively seated at the second valve seat. Fluid flow through the fluid chamber past the valve seats is controlled by the common movement of the connected first and second valves. | 07-30-2009 |
| 20100155510 | NOZZLE TRUMPET - A nozzle extending along an axis is provided, including an orifice portion, an exit and a trumpet portion. The orifice portion includes an orifice dimension that is generally perpendicular to the axis. The exit allows for a fluid to exit the nozzle. The trumpet portion is located between the orifice portion and the exit, where an outer surface of the trumpet portion is angled outwardly towards the exit. The trumpet portion includes a trumpet angle. The trumpet angle is measured at the outer surface of the trumpet portion, where the trumpet angle is less than ninety degrees. A trumpet height is also included, where the trumpet height is measured at the trumpet portion, and the trumpet height is greater than the orifice dimension. | 06-24-2010 |
| 20100259348 | DUAL SIDED CONNECTOR BLOCK - A dual sided connector block for a solenoid is provided which may be used in multiple designs. The dual sided connector block includes a base, a first terminal insertion slot on a first side of the base, a second terminal insertion slot on the second side of the base, a tie-off post, and a magnet wire. The magnet wire is operatively configured as a solenoid coil and is routed inside of the base and wound around the tie off post. The magnet wire is accessible to a connector blade inserted through either the first terminal insertion slot or the second terminal insertion slot. | 10-14-2010 |

| 20110253807 | PRESSURE SWIRL ATOMIZER WITH CLOSURE ASSIST - A pressure swirl atomizer includes a nozzle having an exit orifice and a plurality of tangential swirl channels and a pintle that is movable within a pintle bearing between a closed position that closes the exit orifice and an open position that opens the exit orifice. The atomizer also has a pole piece having a channel, and the pole piece and the pintle are separated by an air gap when the pintle is in the closed position. A space between the pintle and the pintle bearing, the air gap, and the channel together form at least a part of a return path. Fluid from the tangential swirl channels drains through the return path when the pintle is in the closed position. To open the atomizer, a solenoid generates a magnetic force when energized, attracting the pintle toward the pole piece into the open position. A check valve disposed in the return path generates a fluid back pressure when the solenoid is de-energized to push the pintle toward the closed position. The fluid back pressure helps prevent the pintle from getting stuck in the open position. | 10-20-2011 |
| 20110253808 | PRESSURE SWIRL ATOMIZER WITH REDUCED VOLUME SWIRL CHAMBER - A pressure swirl atomizer includes a swirl chamber having an exit orifice, a first section with a first volume, and a second section with a second volume. The second volume is smaller than the first volume, and the exit orifice disposed in the second section. The atomizer also includes a pintle movable to open and close the exit orifice and a plurality of tangential swirl channels disposed about a circumference of the swirl chamber. The reduced volume of the second section reduces the amount of static fluid to be accelerated into a flow pattern, thereby improving spray quality when the exit orifice is initially opened. | 10-20-2011 |
| 20110253809 | PRESSURE SWIRL ATOMIZER WITH SWIRL-ASSISTING CONFIGURATION - A pressure swirl atomizer has a swirl chamber with an exit orifice and a plurality of tangential swirl channels disposed around the circumference of the swirl chamber. A pintle bearing surrounds a pintle. The pintle has a body portion and a nose portion that is narrower than the body portion. The nose portion has a tip that opens and closes the exit orifice and a side that is movable in the pintle bearing. In one embodiment, a return path formed between the nose portion of the pintle and the pintle bearing drains fluid from the swirl chamber when the exit orifice is closed. The nose portion positions the return path closer to a centerline of the atomizer, forcing fluid to swirl in the swirl chamber before draining. Since the fluid does not remain static in the chamber, less energy is needed to increase the fluid velocity and quickly form a desired spray pattern when the exit orifice is opened. | 10-20-2011 |
