摘要： An improved rotary fuel distributor is provided which effectively dynamically centers the rotor during operation while actively cooling the rotor and refilling fuel passages to minimize cavitation. A pressure balancing system is provided which includes pressure area defining grooves formed adjacent a rotor outlet port to control the pressure gradient in the clearance between the rotor and the distributor housing thereby effectively providing a more predictable force component which can be controlled to more effectively balance the rotor in conjunction with two balancing ports positioned on the opposite side of the rotor from the outlet port. A refill and cooling system is provided to continuously and actively cool the rotor with cool, low pressure fuel throughout rotation thereby displacing the hot fuel with cool fuel and effectively preventing thermal seizure of the rotor. The refill and cooling system also includes passages for effectively refilling delivery passages formed in the distributor housing while intermittently refilling supply passages with cool, low pressure fuel after each injection event.

摘要： A three-way valve including a valve housing having a valve chamber and a high pressure fluid supply inlet, high pressure fluid outlet and drain communicating with the valve chamber is disclosed. A movable member is reciprocally received in the valve chamber so as to be reciprocated between first and second positions for selectively fluidically communicating the outlet with either the inlet or drain. A first valve seat is formed in the valve housing and concentrically disposed in the valve chamber for sealing communication between the outlet and drain and a second valve seat is concentrically disposed in a cavity formed in the movable member for sealing communication between the inlet and outlet. A floating pin is received in the movable valve member cavity at a one end of the movable valve member and cooperates with the second valve seat for selectively sealing fluidic communication between the inlet and the outlet. An actuating device is mounted on the valve housing adjacent an end of the movable valve member opposite the floating pin for advancing the movable valve member toward the first position when energized and for allowing the movable valve member to retract to the second position when de-energized.

摘要： A fuel injector includes an injector housing having a plunger assembly disposed within a central axial bore and including a lower plunger, an intermediate plunger, and an upper plunger. The lower plunger reciprocates within the central bore to meter a variable quantity of fuel and to inject this fuel during downward portions of the reciprocating motion. A timing chamber formed between the upper and intermediate plungers receives an amount of timing fluid to create a variable length hydraulic link between the plungers. The fluid is drained from the chamber through a drain passage at the end of the injection cycle. The timing chamber has associated with it a mechanism for changing the effective flow function of the drain passage, at a point in the cycle following fuel injection, to maintain a large downward pressure on the lower plunger to hold the lower plunger down and thus prevent additional, undesired fuel flow into the combustion chamber. In a preferred embodiment, the drain passage is located along the central axis of the intermediate plunger, and the upper plunger is provided with a projecting portion which moves into position as the timing chamber collapses to effectively constrict the drain passage, thus changing the timing fluid flow function to a function which provides greater fluid pressure in the timing chamber.

摘要： A piezoelectric-actuated fuel injector for injecting fuel into a combustion chamber of an internal combustion engine is provided which includes a piezoelectric actuator movable to expand in a first direction and movable to contract in a second direction opposite the first direction, and a hydraulic link assembly disposed within a nozzle cavity formed in a nozzle housing containing a nozzle valve element. The hydraulic link assembly is positioned close to the injector orifices to minimize needle valve element length and mass, thereby reducing seat impact forces and enhance response time. A refill valve operates to move into an open position to refill a hydraulic link chamber. An actuator power source operates to vary voltage to cause multiple injection pulses and to selectively maintain the voltage above a predetermined lower level between injection pulses to maintain the refill valve in a closed position to prevent refilling of the hydraulic link chamber.

摘要： A three-way fuel injection control valve assembly is provided which includes a pilot valve for controlling the movement of a drain valve member and a separate supply valve member to minimize valve response time and transition flow losses. The solenoid operated two-way pilot valve controls the flow of fuel from a control volume formed adjacent the ends of the drain valve member and the supply valve member to begin and end an injection event. A transition flow loss limiting feature is provided which causes the drain valve member to close prior to the opening of the supply valve member and subsequently causes the supply valve member to close prior to the opening of the drain valve member during a given injection event thereby minimizing transition flow losses. The transition flow loss limiting feature includes sizing the cross sectional areas of the supply valve member and the drain valve member, sizing a bias plunger for biasing the drain valve member and sizing one or more bias springs so that no opening overlap occurs between the supply valve member and the drain valve member.
