摘要： An improved hydraulically-actuated fluid injector system (10) comprises a hydraulically-actuated fuel pressurization member (74), a fluid storage chamber (94), and a direct-operated check (76). Pressurization of fluid in the storage chamber (94) begins before the start of fluid injection. Fluid injection begins by hydraulically unbalancing the check (76). Fluid injection ends by hydraulically balancing the check (76) to allow a biasing device (78, 82) to close the check (76). Preferably, actuating fluid (32) that is spilled from the fuel pressurization member (74) (to end fuel injection) is communicated to a hydraulic motor (178) which drives a source of pressurized hydraulically-actuating fluid (32). The present invention provides improved control of several fluid injection parameters, including higher peak fluid injection capability and less fluid injection pressure drop at the end of injection, resulting in improved engine performance and lower emissions, noise, and wear. The present invention also improves efficiency of operation due to the above hydraulic energy recovery feature.
摘要翻译：改进的液压致动流体喷射器系统（10）包括液压致动燃料加压构件（74），流体储存室（94）和直接操作支架（76）。储存室（94）中的流体加压在液体注入开始之前开始。流体注射开始于液压不平衡支架（76）。流体注射通过液压平衡支票（76）终止，以允许偏压装置（78,82）关闭支票（76）。优选地，从燃料加压构件（74）溢出（以终止燃料喷射）的致动流体（32）被传递到驱动加压液压致动流体源（32）的液压马达（178）。本发明提供了几种流体注入参数的改进控制，包括较高的峰值流体注入能力和在注射结束时较少的流体注射压降，从而改善发动机性能并降低排放，噪音和磨损。由于上述液压能量回收特征，本发明还提高了操作效率。

摘要： A fuel injector assembly (30) has a fuel injector body (130) containing a nozzle (90) and a nozzle fuel cavity (94), a valve (159) with a valve element (160), a valve fuel cavity (204), a valve fuel cavity (210), a valve seat (162) and a pressure-equalizing fuel cavity (212) to reduce pressure variations at the valve seat (162) when the valve (159) is in a closed position. A fuel supply bore (206) supplies pressurized fuel to valve fuel cavity (204) formed in the valve (159), and the annular pressure-equalizing fuel cavity (212) is disposed adjacent the valve fuel cavity (210) and adjacent a periphery of the valve element (160) to reduce fluid pressure variations in the valve fuel cavity (210) so that the fluid seal at the valve seat (162) is not weakened.

摘要： A variable delivery liquid pump system (16) includes a housing (25) defining an inlet (26), an outlet (30) and a plunger bore (43). A rotating shaft (27) includes a cam (28) that defines a fixed displacement distance D with each rotation of the shaft (27). A plunger (31) is slidably positioned in the plunger bore (43). A supply of liquid at a supply pressure is attached to the inlet (26) by a supply passage (21). An outlet control mechanism (23) includes an electronically-controlled flow restriction valve (20) positioned in the supply passage (21). The plunger (31) retracts less than the fixed displacement distance D of the cam (28) during each rotation of the shaft (27) when the flow restriction valve (20) is at least partially closed. The variable delivery pump (16) is particularly suited for use in a hydraulically-actuated fuel injection system (11).

摘要： An actuator and valve assembly (28) for an electronically-controlled unit injector (18) is disclosed which comprises an electrically-energizable actuator assembly (36) and a device (56) for communicating, collecting and draining damping fluid with respect to at least one cavity (57, 89) of the actuator assembly (36). If too much damping fluid remains in the actuator assembly (36) after engine shutdown, that damping fluid may cool off and cause slow response of the actuator and valve assembly (28) during cold engine starting. The end result is that quick starting and/or operation of the engine (12) may be hindered, particularly under cold engine conditions. The communicating, collecting and draining means (56) permits at least a portion of the hot damping fluid to automatically drain from the cavity (57, 89) after the engine (12) has been shutdown.

摘要： A method of purging fuel supply components for a combustion chamber of a regeneration assembly (36) is disclosed. A regeneration cycle is performed during which fuel is supplied from a fuel source (22) to the combustion chamber with fuel supply components including a fuel supply circuit (48) and at least one fuel injector unit (40). At least a first purging cycle is initiated to purge residual fuel from the fuel supply components. During the purging cycle, a flow of purging gas is directed to the at least one fuel injector unit (40) to purge residual fuel from the at least one fuel injector unit (40). Also during the purging cycle, a flow of purging gas is directed to the fuel supply circuit (48) to purge at least a portion of the fuel in the fuel supply circuit (48) toward the fuel source (22).

摘要： A valve system having a valve operated by a piezoelectric device (122) to control the flow of fluid through the valve system. Movement of the valve is controlled by a pre-stressed bender actuator (122) that changes its shape by deforming in opposite axial directions in response to a control signal applied by an actuator control system. The valve system may comprise a common rail fuel injector (100a), electrohydraulic actuator system, electronically-controlled fuel injector, gasoline port injector, fluid metering valve, relief valve, reducing valve, direct valve or direct-injection gasoline injector.

摘要： On décrit un ensemble actionneur et soupape (28) d'un injecteur à commande électronique (18), comprenant un ensemble actionneur pouvant être excité électriquement (36) et un dispositif (56) pour faire communiquer, capter et drainer le fluide d'amortissement par rapport à au moins une cavité (57, 89) de l'ensemble actionneur (36). S'il y a un excédent trop important de fluide d'amortissement dans l'ensemble actionneur (36) après l'arrêt du moteur, ce fluide d'amortissement peut refroidir et provoquer une réaction lente de l'ensemble actionneur et valve (28) lors du démarrage à froid du moteur. Le résultat final est que cela peut empêcher le moteur (12) de démarrer à froid et/ou de fonctionner, notamment lorsque celui-ci est froid. L'élément de communication, récupération et drainage (56) permet au moins à une partie du fluide d'amortissement chaud de s'évacuer automatiquement de la cavité (57, 89) après l'arrêt du moteur (12).

摘要： Le circuit de commande à soléinoïdes décrit (160) alimente en courant des solénoïdes sélectionnés (168a-168c) pour commander l'actionnement d'une soupape de commande d'un injecteur de carburant et, de ce fait, le réglage et la durée de l'injection de carburant dans chacun des cylindres d'un moteur à combustion interne. Le courant alimentant chacun des solénoïdes est également régulé de façon à présenter une forme d'onde de courant à trois étages (B) comportant un niveau de courant d'accrochage (B1), un niveau de courant de maintien (B3) et un niveau de courant intermédiaire (B2). L'excitation du solénoïde au niveau de courant d'accrochage (B1), fait démarrer le mouvement de la soupape de commande. Après le début du mouvement de la soupape de commande, le niveau de courant est réduit au niveau intermédiaire (B2), qui est inférieur au niveau de courant d'accrochage (B1) mais qui est suffisamment élevé pour faire continuer le mouvement de la soupape de commande. Le niveau de courant est ensuite encore réduit, jusqu'au niveau de maintien (B3), qui est inférieur aux deux autres niveaux de courant mais suffisant pour maintenir la soupape de commande dans la position adoptée après mouvement. Le solénoïde est ensuite désexcité et la soupape de commande revient à sa position initiale pour arrêter le flux de carburant alimentant le moteur. Ce processus est répété pour chacune des autres soupapes de commande des injecteurs de carburant, de façon à économiser l'énergie et à réduire la dissipation de chaleur.
