摘要： A fuel injector for fuel injection systems of internal combustion engines and a method of manufacturing same are described. The fuel injector includes a valve seat body into which a valve seat face is introduced, which cooperates with a valve closing body to form a sealing seat, and a nozzle body to which the valve seat body is fixedly connected. The valve seat body is insertable into the interior of the nozzle body and on its downstream side it has a partially spherical outside geometry, which rests on a bearing surface of a seat body recess in the nozzle body. Valve seat body is mounted so it can rotate relative to the nozzle body on the bearing surface until its position is finally secured, and it may be aligned by a centering mandrel.

摘要： A fuel injector, particularly a fuel injector for fuel injection systems in internal combustion engines, has a valve needle, which cooperates with a valve-seat surface to form a sealing seat, and an armature, which engages with the valve needle, the armature being movable along the axis of the valve needle and being damped by a damping element made from an elastomer. In this context, a first intermediate ring is situated between the armature and the damping element. The damping element rests on the flange, which is connected in a force-locking manner to the valve needle. The intermediate ring and/or the flange is furnished with radial and/or axial channels which connect an interior volume located between the valve needle and the damping element to a central cutaway of the fuel injector.

摘要： A dual-coil outwardly-opening fuel injector including a fuel tube connected at a lower end to a lower injector housing. Within the fuel tube are a lower (opening) solenoid pole piece, a specially-formed armature, and an upper (closing) solenoid pole piece. A seat assembly including an injector nozzle, swirler, and valve seat are adjustably threaded into the lower housing. A pintle assembly, including a solid pintle portion supporting a valve head and a tubular portion welded thereto, is axially disposed within the fuel tube and is welded to the armature which is spaced from the lower pole piece by a distance equal to the opening stroke of the valve. A return spring adjustment mechanism disposed on the upper pole piece engages the upper end of the pintle assembly for varying the closing force of the return spring. Opening and closing solenoid preassemblies are mounted external to the fuel tube for magnetically engaging the pole pieces and armature within in known fashion.

摘要： An airbag inflation nozzle assembly for fluidic mating with an inflation valve assembly, including an inflation valve stem, upon an inflatable cargo airbag comprises a housing, and an inflation nozzle member, having an inflation nozzle tip, pivotally mounted within the housing between a first position at which the inflation nozzle tip is fluidically disengaged from the inflation valve assembly, and a second position at which the inflation nozzle tip is fluidically engaged with the inflation valve assembly. A transversely oriented camming button is movably mounted upon the housing between an UNLOCKED position so as to permit the inflation nozzle member to be moved to the first fluidically disengaged position with respect to the valve assembly, and a LOCKED position which forces the inflation nozzle member to be moved to the second fluidically engaged position with respect to the valve assembly. The housing further comprises a pair of oppositely disposed side rails upon which a valve body portion of the valve assembly can be slidably supported as the housing of the inflation nozzle assembly is being operatively mated with the valve assembly, and an end wall flange portion for engaging a valve body member of the valve assembly during operative mounting of the housing upon the valve assembly so as to ensure coaxial alignment of the inflation nozzle tip with the inflation valve stem.

摘要： A one touch valve for activating fluid flow between an inlet conduit and an outlet conduit is disclosed. The valve has a flow cylinder defining an inflow chamber in fluid communication with the inlet conduit and an outflow chamber in fluid communication with the outlet conduit. The flow cylinder includes an end plate and an intermediate plate having a center collar with an aperture. A flexible diaphragm is provided with a sealing surface in contact with the collar to create a seal. The diaphragm has an edge coupled to the intermediate plate and a small diameter hole providing fluid contact between the inflow chamber and an intermediate chamber which is defined by the intermediate plate of the flow cylinder. A plunger is placed on the diaphragm to create a seal with the opposite surface of the diaphragm from the sealing surface. A shaft has one end connected to the plunger and extends through the aperture of the diaphragm. A spring is located between the end plate of the flow cylinder and the contact surface of the plunger. Pushing the shaft causes the plunger to separate from the diaphragm creating fluid pressure on the diaphragm contact surface to push the plunger toward the end plate end, compressing the spring, and causing the diaphragm to separate from the collar causing fluid to flow from the inflow chamber through the aperture to the outflow chamber. Releasing the shaft causes the spring to decompress, forcing the plunger and diaphragm away from the end plate re-establishing the seal between the sealing surface with the collar preventing fluid flow from the intermediate chamber to the outflow chamber.
摘要翻译：公开了一种用于在入口导管和出口导管之间激活流体流动的单触式阀。阀具有限定与入口管道流体连通的流入室的流动缸和与出口导管流体连通的流出室。流动缸包括端板和具有带孔的中心轴环的中间板。柔性膜片设置有与套环接触的密封表面以形成密封。隔膜具有联接到中间板的边缘和小流径孔，其在流入室和由流动缸的中间板限定的中间室之间提供流体接触。柱塞被放置在隔膜上以产生与隔膜的与密封表面相对的表面的密封。轴的一端连接到柱塞并延伸穿过隔膜的孔。弹簧位于流动缸的端板和柱塞的接触表面之间。推动轴使柱塞与隔膜分离，在隔膜接触表面上产生流体压力，以将柱塞推向端板端，压缩弹簧，并使隔膜与轴环分离，使流体从流入室通过孔到流出室。释放轴使得弹簧减压，迫使柱塞和隔膜远离端板，重新建立密封表面与轴环之间的密封，防止流体从中间室流出到流出室。

摘要： A solenoid valve is provided which may be used to inject fuel into an internal combustion engine for automotive vehicles. The solenoid valve includes an armature and stator attracting the armature to open a fluid passage. The solenoid valve also includes a retaining nut and an end body. The retaining nut engages a housing to retain a hollow cylindrical stator casing in the housing. The end body is joined to the casing in alignment therewith to hold the stator within the casing without subjecting the stator to the pressure produced by the engagement of the retaining nut with the housing. This minimizes undesirable loads on the stator.

摘要： In a fuel injection valve in which an outer frame member is press fitted to a limited region of an outer circumference of an inner pipe member in a state that a drive coil is radially sandwiched therebetween, a valve lift amount is accurately adjusted by press fitting the attracting member to the inner pipe member without being adversely affected by a possible deformation of the inner circumference of the inner pipe member on press fitting the outer frame member to the inner pipe member due to a relief space provided in the inner circumference of the inner pipe member for preventing the outer circumference of the attracting member from contacting the inner circumference of the inner pipe member at least at a position just radially inside and axially corresponding to the limited region.
