Abstract: A fluid control device for use in a high pressure fluid system, the device including a device body with a cavity and a high pressure circuit, a plunger positioned for reciprocal movement in the cavity, and a leakage reduction cap mounted to the plunger for reducing fluid leakage flow. In one implementation, the leakage reduction cap includes a flexible portion positioned between the device body and the plunger, and defining an annular clearance gap between the leakage reduction cap and the device body. The flexible portion of the leakage reduction cap resiliently flexes radially outwardly in response to fluid pressure forces to reduce the annular clearance gap so as to minimize fluid leakage flow through the annular clearance gap.

Abstract: A fuel injector is provided with a lower nozzle body which is cooled with a small amount of metered fuel. In one embodiment, a blind passage is formed to extend from the upper portion to the lower end of the injector nozzle valve element. A transverse passage is formed in the nozzle valve element connecting the blind passage and the nozzle bore. Rail pressure causes a metered amount of fuel to flow through the nozzle bore, the transverse passage and upwardly along the blind passage to the drain passage. Inward cooling occurs by providing more surface area over which the fuel flows. In another embodiment, a sleeve is formed to fit over an existing nozzle to form a passage surrounding the injector tip. An orifice is located in the nozzle housing to connect the nozzle cavity with the annular passage thereby providing a small amount of fuel to drain.

Abstract: A solenoid actuated valve assembly is provided which achieves accurate control of valve movement while maximizing valve seat life. Specifically, the solenoid actuated flow control valve assembly includes a valve plunger, a solenoid actuator including a coil and an armature, and an armature overtravel feature for permitting continued movement of the armature relative to the valve plunger from an engaged position into a disengaged position when the valve plunger reaches a closed position. The armature overtravel feature includes an overtravel biasing spring for returning the armature from the disengaged position to the engaged position prior to subsequent energization of the actuator coil. As a result, the overtravel feature minimizes the mass impacting the valve seat thereby extending valve seat life while, importantly, avoiding lost motion in the armature during the next actuation cycle thereby minimizing valve response time. The flow control valve also includes an armature protecting feature for minimizing armature wear by preventing the armature from contacting the valve plunger and an armature stop.

Abstract: A fuel injector is provided that creates variable spray characteristics to effectively reduce emissions, such as NOx emissions and particulate matter. The injector includes a nozzle valve element of the outwardly opening type including a fuel delivery passage and spray holes. The nozzle valve element is operable to move to a low lift position to cause fuel flowing from the spray holes to impinge on the injector body and to deflect toward the combustion chamber, and to move to a high lift position to cause fuel flowing from the spray holes to avoid impingement on injector body and flow in an obstructed manner directly into the combustion chamber. An annular chamber may be formed in the nozzle valve element adjacent the spray holes to receive fuel.

Abstract: The operation of a fuel injector for an internal combustion engine is controlled, wherein the fuel injector has an on time comprising a pull-in time during which injector current increases to a pull-in current followed by a hold time during which the injector current is limited to a hold current that is less than the pull-in current. A control circuit receives a pressure signal from a pressure sensor that corresponds to a pressure of fuel supplied to the fuel injector for injection into the engine, correlates the pressure signal with fuel pressure, and decreases the pull-in time with increasing fuel pressure.

Abstract: A preferred embodiment EGR valve permits exhaust gas to be induced into the intake line downstream of the compressor, while minimizing the need to reduce the size of the turbocharger. The preferred embodiment EGR valve exploits variations around the mean pressure in the EGR passage created by the engine cycle by selectively opening when the pressure in the EGR valve exceeds the pressure in the intake line. Thus, exhaust gas is recirculated even when the engine is running near torque peak. The preferred embodiment EGR valve also exploits the higher mean pressure in the exhaust line relative to the intake line at higher engine speeds by remaining open, in order to minimize the energy consumed in opening and closing the EGR valve.

Abstract translation: 优选的实施方案EGR阀允许排气被吸入到压缩机下游的进气管路中，同时最小化减小涡轮增压器尺寸的需要。 EGR阀利用在发动机循环所产生的EGR通路中的平均压力周围的变化，当EGR阀中的压力超过进气管线中的压力时，选择性地打开EGR阀。 因此，即使当发动机在扭矩峰值附近运行时，废气也被再循环。 在优选实施例中，EGR阀还通过保持打开来利用在较高发动机转速下相对于进气管线的排气管线中较高的平均压力，以便最小化打开和关闭EGR阀时消耗的能量。
