20080257989 | Fuel Injector with Balanced Metering Servovalve, for an Internal Combustion Engine - The injector comprises a balanced metering servovalve to control a rod for the opening/closing of a nozzle. La servovalve has a valve body with a control chamber radially delimited by a tubular portion and fitted with an outlet passage that is opened/closed by an axially movable shutter. The servovalve is also integral with an axial stem, provided with a lateral surface, through which the outlet channel exits. The shutter is coupled to the stem in an axially sliding manner and, when it closes the outlet passage, it is subjected to substantially null axial fuel pressure. The outlet passage has a calibrated segment distanced from the shutter and close to a bottom wall of the control chamber. The calibrated segment is carried by an element fixed to the valve body in correspondence to an axial segment of the outlet passage. | 10-23-2008 |
20090032620 | METERING SERVOVALVE AND FUEL INJECTOR FOR AN INTERNAL COMBUSTION ENGINE - A metering servovalve for a fuel injector of an internal combustion engine has an electro-actuator and a fixed valve body, which defines a control chamber communicating with an inlet and with an outlet channel. The outlet channel has at least one calibrated restriction and exits through the lateral surface of an axial stem, on which a sleeve slides, in a substantially fluid-tight manner, to open/close the outlet channel and so vary the pressure in the control chamber. The outlet channel is closed by an end portion of the sleeve that is elastically deformable in a radially outward direction, under the thrust of the fuel pressure, to increase the diameter at which the seal against the valve body is formed, with respect to a non-deformed state, and to generate a radial unbalancing force on the sleeve upon opening when the outlet channel is closed. | 02-05-2009 |
20090320801 | FUEL INJECTOR WITH HIGH STABILITY OF OPERATION FOR AN INTERNAL-COMBUSTION ENGINE - The injector comprises a dosing servo valve for controlling a rod for opening/closing a nebulizer. The servo valve has a valve body having a control chamber provided with an outlet passage that is opened/closed by an open/close element that is axially movable. The open/close element is separate from an anchor of an electromagnet, and is slidable on an axial guide element for closing the outlet passage. The open/close element is held in the closing position by a spring acting through an intermediate body. The anchor can be displaced with respect to the axial guide element between a flange of the intermediate body and a projection element of the guide member, for eliminating the rebounds of the open/close element upon closing of the solenoid valve. | 12-31-2009 |

20130206871 | GASEOUS-FUEL-INJECTOR DEVICE FOR INTERNAL-COMBUSTION ENGINES - In a gaseous-fuel-injector device for internal-combustion motor-vehicle engines, the valve body of the injector device has one or more auxiliary openings giving out onto an internal surface of the valve body in which the valve member of the injector device is slidably mounted. Said auxiliary openings are arranged in such a way as to enable the inflow of the gaseous fuel coming from the supply, not only into the inlet opening of the injector device, but also into the internal area of the valve body in which the valve member is slidably mounted, so as to obtain an effect of ventilation and flushing, by means of the flow of gaseous fuel, in an area where there tend to form deposits of the oily substances contained in the gaseous fuel. | 08-15-2013 |

20140152788 | Multi-Tablet Projector - An adaptive projector to project an image from a digital device may include an adaptive socket to cooperate with the digital device, a image sensor to sense a image from the digital device and a projector screen to project the image from the digital device. The adaptive socket may be adaptable to remove and replace the digital device. | 06-05-2014 |
20140245553 | TOOTHBRUSH WITH INDEPENDENTLY ADJUSTING BRISTLE CLUSTERS - A toothbrush of the invention uses magnetic repulsion phenomenon to effectively clean teeth surface. The head of the toothbrush accommodates plurality of bristle clusters, each cluster having a magnet affixed to its base. Another magnet is positioned underneath such base and aligned so that identical poles of both magnets face one another. Such alignment generates magnetic repulsion which, when combined with the brushing motion initiated by user, ensures that bristle clusters individually adjust to irregular teeth surface and reach deep into separation between adjoining teeth thus ensuring effective cleaning of the teeth and gaps between them. | 09-04-2014 |

20100276533 | Thermal Energy Radiance Expander - A specially design missile system use for hindering the centrifugal forces inside vortexes commonly known as tornados. The missile system composed of a typical modified vehicle with a design platform. The platform is design of the insides of a platform that contains liquid and compressed gas. A command and control module and a projectile missile system complement above the platform. When a super cell appears and probable starting of tornado activity commences the Thermal Energy Radiance Expander system is send over to the targeted area. As the initial start of the tornado commences the vehicle and whole system is sent to the target area. The missile is then loaded with the gaseous element turn live and launch on to the target. The missile control through the command module explodes intentionally at the side of the vortex. The aim of the system is to break and hinder further activity of the vortex hence terminating tornado. | 11-04-2010 |
