摘要： A fuel injector includes an injector body with a plunger bore, a nozzle chamber, and a nozzle outlet that opens to the nozzle chamber. A plunger is positioned to reciprocate in the plunger bore between an advanced position and a retracted position. A portion of the plunger and a portion of the plunger bore define a fuel pressurization chamber. At least one of the injector body and the plunger define a main passage extending between the fuel pressurization chamber and the nozzle chamber. At least one of the injector body and the plunger define a restricted passage extending between the fuel pressurization chamber and the nozzle chamber. The restricted passage restricts flow of fuel to the nozzle chamber over the beginning portion of each injection event. The main passage is substantially closed over a portion of the plunger's movement between its retracted position and its advanced position.

摘要： A spool comprises: a hub sandwiched between two flanges. At least one of the flanges includes at least one smoothly curving arcuate fiber groove on a side facing the hub. The fiber groove extends substantially to the outer edge of said flange. The groove is situated at a shallow angle θ relative to the tangent line to the periphery of the flange, the angle θ being no more than 15 degrees.

摘要： A hydraulically-actuated fuel injection system includes a manifold holding an amount of pressurized actuation fluid therein. A plurality of hydraulically-actuated fuel injectors each has an injector body that defines an actuation fluid cavity adjacent a piston. A plurality of branch passages each has one end connected to the manifold and a second end connected to the actuation fluid cavity of a different one of the plurality of hydraulically-actuated fuel injectors. A flow orifice valve member is positioned in each of the branch passages and is moveable between a first position that presents a relatively small flow area through the branch passage when pressure in the manifold is relatively low, and a second position that presents a relatively large flow area when pressure in the manifold is relatively high.
摘要翻译：液压致动燃料喷射系统包括在其中保持一定量的加压致动流体的歧管。多个液压致动燃料喷射器各自具有限定邻近活塞的致动流体腔的喷射器主体。多个分支通道各自具有连接到歧管的一端和连接到多个液压致动燃料喷射器中的不同一个的致动流体腔的第二端。流量孔阀构件定位在每个分支通道中，并且可在第一位置和第二位置之间移动，第一位置在歧管中的压力相对较低时通过分支通道呈现相对较小的流动面积;以及第二位置，其呈现相对较大的流量歧管中的压力相对较高时的区域。
