摘要： An improved fuel injection spray director plate including conically chamfered entries to the flow passages through the plate. The conical chamfer may extend part way or all the way through the plate. In a currently preferred embodiment, the chamfer extends only part way through the plate, and the remaining cylindrical portion of the passage provides desirable directional capability for the spray. Preferably, the conical chamfer axis forms an angle with the cylindrical portion axis. Preferably, a flow passage is positioned in the director plate such that the main flow direction of fuel exiting the fuel injector valve is received into the chamfer of the passage. Preferably, a second conical portion is formed in the passage between the first conical portion and the cylindrical portion.

摘要： An injector fuel injection valve is guided at the lower end by a plastic valve guide mounted in a nozzle containing a valve seat engagable by the valve element. The valve guide includes inwardly protruding annularly spaced ribs having inner guide surfaces and defining spaced flow channels. The guide surfaces engage the circular or spherical exterior of the valve element to guide the element to properly aligned seating against the conical valve seat. The plastic or polymeric valve guide is preferably molded in place within the cup shaped metal nozzle but, if desired, the valve guide may be separately molded and subsequently inserted or snapped in place within the nozzle. A second plastic valve guide may be provided for guiding the upper end of an associated armature. A plastic or polymeric ring is molded in place or otherwise mounted within a groove around the outer surface of the armature and engagable with a cylindrical tube disposed within a main body of the injector to which the injection nozzle is secured.
摘要翻译：喷射器燃料喷射阀在下端通过安装在包含可由阀元件接合的阀座的喷嘴中的塑料阀引导件引导。阀导向器包括向内突出的环形间隔的肋，其具有内引导表面并且限定间隔开的流动通道。引导表面接合阀元件的圆形或球形外部，以将元件引导到抵靠锥形阀座的适当对准的座。塑料或聚合物阀引导件优选地模制在杯形金属喷嘴内的适当位置，但是如果需要，阀引导件可以分开模制并随后在喷嘴内插入或卡扣就位。可以设置第二塑料阀引导件以引导相关电枢的上端。将塑料或聚合物环模制在适当位置或以其他方式安装在围绕电枢的外表面的槽内，并与设置在喷射器的主体内的圆柱形管接合，注射喷嘴固定到该圆柱形管上。
