| 20090261184 | Fuel injector with direct shutter actuation for internal combustion engines - A fuel injector for internal combustion engines provided with a fuel feeding channel, the feeding channel having an axis and an injection outlet; an injection valve to control the outlet; an injection valve having a shutter arranged inside the feeding channel to define, within the feeding channel, a first fuel introduction section, the shutter being movable from and to a closing position along the feeding channel, which has a second section; and an annular sealing seat arranged on the feeding channel upstream of the outlet; an elastic member for normally keeping the shutter in the closing position; an actuator mechanism connected to the shutter to displace the shutter itself from the closing position and to an opening position of the outlet; and a hydraulic resistance that is provided along the feeding channel upstream of the annular sealing seat to balance the forces acting upon the shutter. | 10-22-2009 |
| 20100084494 | Resonant Supersonic Gas Valve and Nozzle - A high speed valve has a conductive flyer plate responsive to eddy currents induced by an adjacent coil. The eddy currents generate a repulsive force which opens the valve, and a low-mass flyer plate and spring combined with a resonant plate and spring combination provide a fast opening and closing time for the valve. A nozzle structure directs a supersonic flow of gas into a rectangular array of high-density gas suitable for interaction with a laser beam transverse to the rectangular array of jets for the production of wakefield interaction, leading to very high-energy electrons from the gas jet. | 04-08-2010 |
| 20100140380 | Fluid Injection Valve - A fluid injection valve having an inlet which is set up to receive fluid from a supply line and is connected to a chamber, a fluid outlet which is connected to the chamber, is set up to allow fluid to flow out of the fluid injection valve and has a valve arrangement having a valve seat and a valve element, wherein the valve element is set up to perform opening and closing movements relative to the valve seat, a linear actuator which is set up to move the valve element relative to the valve seat, and a spring arrangement which exerts on the valve element a force which is dependent on the fluid pressure prevailing in the chamber. | 06-10-2010 |
| 20100258657 | Fuel injector having a disk valve with a floating, compliant injector seat - An improved disk-valve fuel injector comprising a self-centering, floating valve seat insert disposed in a valve body. The valve seat insert includes a circular first valve seat and the body includes a circular second valve seat concentric with the first valve seat. A spring urges the valve insert into compliance with a disk-shaped valve head. The valve insert is able to adjust position in all three dimensions, allowing the disk head to mate precisely with both seats, thereby minimizing leakage when the valve is closed, improving metering precision, and extending the working lifetime of the valve head and valve seats. | 10-14-2010 |
| 20110180635 | High Pressure Fuel Injector Seat That Resists Distortion During Welding - A valve seat ( | 07-28-2011 |
| 20120024987 | DEVICE FOR THE ADMINISTRATION OF INJECTABLE PRODUCTS WITH A CONTROLLED FLOW RATE - A device is for the administration of injectable products with controlled flow rate, with a container ( | 02-02-2012 |
| 20120067982 | FUEL INJECTOR - A fuel injector that includes a sliding armature, decoupled armature, or flying armature movable between a pintle stop and a housing stop. Flying armatures are generally used to increase the total force applied to the pintle stop for lifting the pintle off a nozzle seat to open the fuel injector. When the fuel injector is turned off, a housing stop is arranged to absorb kinetic energy present in the flying armature so that the kinetic energy is not imparted to the nozzle seat. | 03-22-2012 |
| 20130075501 | FUEL INJECTOR - Improving the injection fuel mass accuracy of fuel injector, it is necessary to make the fuel injector perform seat valve opening and closing operation quickly. When the shapes of a fixed core and an anchor are optimized to improve the responsiveness of a magnetic flux, it is necessary to ensure a sufficient fuel path area while preventing adhesion by making the adherence phenomenon rarely occur between an end face of the anchor and an end face of the fixed core. A through hole passes through an anchor forming an armature of an electromagnetic fuel injector from a face of the anchor where the anchor faces a fixed core to a back face where the through hole has a large-diameter portion and a small-diameter portion, and the large-diameter portion is located in an upstream part and is offset to the outer periphery with respect to the small-diameter portion. | 03-28-2013 |
