摘要： The invention relates to a fuel injection valve (1) for fuel injection systems of internal combustion engines. Said fuel injection valve comprises a valve closing element (4) that is functionally linked with a valve needle (3) and that interacts with a valve face (6) of a valve seat (5) to give a sealing seat. The valve is further provided with a swirl-producing element that is located downstream of the sealing seat in the valve seat (5) and whose center axis (38) preferably includes an angle different from zero with the center axis (39) of the fuel injection valve (1). The swirl-producing element is a threaded rod (36) that is press-fitted into the valve seat (5).

摘要： A system and process for polishing and radiusing a microhole (52). A liquid slurry with particular rheological properties accelerates as it flows through the microhole (52) to abrade the edge of the microhole (52). When the flow rate reaches a target flow rate the process stops and the microhole (52) is properly calibrated.

摘要： The liquid droplet ejection apparatus 10 includes a liquid supply path 21, a plurality of mutually independent pressurizing chambers 22, a plurality of liquid introduction bores 23 for establishing communication between the corresponding pressurizing chambers 22 and the liquid supply path 21, and a plurality of ejection nozzles 24 for establishing communication between the corresponding pressurizing chambers 22 and the exterior of the liquid droplet ejection apparatus 10. An ejection bore 24a formed at the end portion of the ejection nozzle 24 assumes a hollow cylindrical form and is formed such that the inside diameter thereof increases toward an ejection opening. When a potential difference is applied between two electrodes of the piezoelectric/electrostrictive element 17, a ceramic sheet 16 forming the upper wall of the pressurizing chamber 22 deforms to thereby cause a change of the volume of the pressurizing chamber. Thus, liquid pressure within the pressurizing chamber increases to thereby cause simultaneous ejection of a plurality of liquid droplets from the ejection opening.

摘要： This fuel injection valve has an injector plate (23) arranged downstream of a valve seat (29). The injector plate is characterised in that a plurality of swirl-generating elements (40) are arranged at its inflow side and are followed by at least one uninterrupted ring-shaped slot (45). The swirl-generating elements (40) are arranged in the manner of a blade wheel, in that each individual element (40) extends substantially in the radial direction and is tilted in the circumferential direction, and in that the elements (40) follow each other in a circle. The ring-shaped slot (45) defines the injection geometry. This arrangement allows fuel to be finely and uniformly sprayed without requiring additional energy. The breaking-down into smallest droplets results in a further reduction of the internal combustion engine exhaust fume emission and also in a reduction of fuel consumption. This fuel injection valve is particularly useful for fuel injection systems of high compression ratio, spark-ignited internal combustion engines.

摘要： Eine Kraftstoffeinspritzdüse besteht aus einem in einer Düsenkuppe (3) endenden Düsengehäuse (1) und einer in diesem geführten Düsennadel (7), die federnd gegen einen konischen Ventilsitz (4) in der Düsenkuppe (3) gedrückt wird, welcher konische Ventilsitz (4) mehrere vom konischen Ende (8) der Düsennadel überdeckte Spritzbohrungen (15) aufweist und in ein Sackloch (6) übergeht, wobei am Ende der ersten Hubphase die jeweilige gedachte Zylindermantelfläche (M), die sich in Verlängerung jeder Spritzbohrung (15) zwischen dem konischen Ende (8) der Düsennadel (7) und dem konischen Ventilsitz (4) ergibt, kleiner als die Querschnittsfläche (Q) der jeweiligen Spritzbohrung (15) ist. Um das Emissionsverhalten insgesamt weiter zu verbessern, ist die gedachte Zylindermantelfläche (M) maximal 0,3 mal der Querschnittsfläche (Q) der jeweiligen Spritzbohrung (15) und die Eintrittszone (17) in die Spritzbohrung (15) ist mit einem Radius von mindestens einem Zehntel des Durchmessers der Spritzbohrung (15) abgerundet.

摘要： An injector nozzle used with an internal combustion engine for shaping a fluid flow is provided. The nozzle has a body and an orifice plate provided at an outlet of the body. The body and the plate extend symmetrically with respect to a central axis. The plate has an interior surface and an opposite exterior surface, which are substantially parallel to each other to define a thickness of the plate. The plate has fluid passageways each having an orifice on the exterior surface. The fluid flow diverges through the fluid passageways to create stream jets. The imaginary extensions the passageways converge to create a focal point and an included angle associated with the focal point.
