| 20090020630 | Fuel injector with deterioration detection - A fuel injection apparatus with a deterioration detection device that includes a volume changing chamber, the volume of which is determined by fuel pressure inside the injector. After injector nozzle opens, the time for the volume changing chamber to change from an initial volume to a target volume is measured and used for calculating changes in nozzle orifice size. The value of orifice size change can be used for both diagnosing injector deterioration and compensating fuel flow rate in a feedback control. In addition to detecting injector deterioration and failures, the volume changing device also dampens effects of noise in fuel pressure to fuel flow rate control and decreases chances of after-injection and second injection. | 01-22-2009 |

| 20110006133 | PRESSURE DIFFERENTIAL MOTOR CONTROL SYSTEM AND METHOD - A pressure differential motor control system for controlling a motor of a high volume low pressure (HVLP) spray system via a pressure differential. The pressure differential motor control system has an outlet fitting connected to a turbine assembly, and a pressure switch adapted to be activated by a pressure differential from the outlet fitting. The outlet fitting has a first section connected to the turbine assembly, a mid section featuring low and high pressure ports, a second section connected to a quick coupler hose and spray gun, and a venturi defined through the outlet fitting. The low pressure port is in communication with the venturi, and the high pressure port is in communication with the input side of the outlet fitting. The pressure switch is activated by a pressure differential from the low and high pressure ports of the outlet fitting, thereby sending a signal to a motor controller for controlling a motor of the turbine assembly. | 01-13-2011 |
| 20120012678 | Sprinkler With Pressure Regulation - A sprinkler pressure regulator module has a compact arrangement with a shiftable member having an upper cavity for receiving water flow debris, and a portion of a bypass valve may reciprocate therein. The module includes a stator plate directing water into a drive mechanism, such as a turbine drive mechanism. The shiftable member receives fluid flow from a radially outboard direction and is sealed with a cup portion receiving the shiftable member to define a cup cavity. A module exterior surface is separated from a sprinkler housing to define a vent cavity. A pressure release vent communicates with the cup cavity, a vent channel between the cup portion and the exterior surface, the vent cavity, and the exterior environment. The vent cavity and cup portion provide receptacles for debris deposit. Ribs around an opening of the vent channel with the vent cavity generally prevent debris from entering the vent channel. | 01-19-2012 |
