摘要： 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.

摘要： In accordance with preferred embodiments of the invention a timing adjustment device includes a cam follower that is engaged between an overhead cam and an injector rocker arm, and is mounted on a rotatable eccentric shaft. The geometry of the eccentric shaft and cam follower is designed so that, as timing is varied by rotation of the eccentric shaft, no change is produced in the vertical height of the rocker arm when the cam shaft is on the outer base circle and the injector is bottomed, in order to assure that the "mechanical crush" of the PT type injector is constant despite changes in timing. In a first application of the timing arrangement, it is used together with a simple injector, which does not utilize a multi-plunger arrangement to form a hydraulic link, to achieve lower parasitic losses. To obtain independent control over injection pressure and timing, a fuel injector in which a hydraulic link is formed between plungers of a multi-plunger arrangement is used with the timing arrangement in order to allow the injection pressure to be maintained constant over a wide range of engine speeds without interfering with engine timing.

摘要： 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.

摘要： A valve for selectively permitting the flow of fluid therethrough is disclosed including a housing having at least one inlet and at least one outlet, a valve seat provided in the housing about the inlet, a displaceable ball for cooperating with the valve seat for sealing fluidic communication between the inlet and outlet and a ball guide for guiding the ball between a closed position in contact with the valve seat and an open position spaced from the valve seat. The ball guide includes a central bore for reciprocally receiving the ball and a plurality of circumferentially spaced fluid passages in fluid communication with the inlet, the passages extending substantially parallel to a longitudinal extent of the central bore such that a flow of fluid through the inlet is directed radially outwardly from the central bore and into the circumferentially spaced passages when the ball is in the open position. Fluid flow through the valve seat is thus restricted to flow through a sharp right angle bend allowing more fluid momentum to be used to hold the ball in a stable position. Accordingly, a majority of the flow is directed underneath the ball and only a small amount of flow goes through the clearance between the ball and the central bore of the ball guide, such that the ball is maintained in a stable condition thus resulting in more consistent flow metering.

摘要： A high pressure control valve according to the present invention provides effective and predictable control of a timing fluid and injection fuel metering system of an internal combustion engine. The control valve includes an armature that abuts against a majority of the surface of a valve element to help minimize beating problems. In addition, a compliant web means provides a flexing motion when the valve element seats with a valve seat to mitigate problems of seat beating. Furthermore, the present invention reduces the number of parts of the control valve to achieve simplicity in structure and lower costs, including eliminating the need for a valve stop pin.

摘要： 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.

摘要： 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.

摘要： 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.
