摘要： A fuel injector assembly having a valve with a valve seat and at least one pressure-equalizing fuel cavity to reduce pressure variations at the valve seat when the valve is in a closed position. The fuel injector assembly has a fuel injector body and a fuel inlet formed in the fuel injector body. A nozzle with a nozzle fuel cavity is formed in the fuel injector body, and a nozzle check is disposed for reciprocating movement in the nozzle. A valve having a valve element and a valve seat is disposed in the fuel injector body. The valve element has a first position relative to the valve seat in which the fuel inlet is fluidly isolated from the nozzle fuel cavity and a second position relative to the valve seat in which the fuel inlet is fluidly coupled to the nozzle fuel cavity. A fuel supply bore supplies pressurized fuel to a valve fuel cavity formed in the valve, and an annular pressure-equalizing fuel cavity is disposed adjacent the valve fuel cavity and adjacent a periphery of the valve element to reduce fluid pressure variations in the valve fuel cavity so that the fluid seal at the valve seat is not weakened.

摘要： A solenoid control circuit provides energy to selected solenoids to control actuation of a control valve of a fuel injector and, hence, the timing and duration of fuel delivered to each cylinder of an internal combustion engine. The current provided to each solenoid is also controlled to provide a three tier current waveform having a pull-in current level, a hold-in current level, and an intermediate current level. Energizing the solenoid at the pull-in current level starts movement of the control valve. After the control valve starts to move, the current level is reduced to the intermediate level, which is less than the pull-in current level, but great enough to continue movement of the control valve. Further reduction of the current level to the hold-in level, which is less than either of the other current levels but sufficient to hold the control valve at the moved position. The solenoid is then de-energized and the control valve returned to its initial position to stop the flow of fuel to the engine. The foregoing is repeated for each of the other control valves of the fuel injectors to save energy and reduce the heat to be dissipated.

摘要： A rotor balancing arrangement is provided for use in a distribution valve to ensure hydrostatic balancing of a rotor located in the distribution valve. Some balancing arrangements provide areas equally spaced around the peripheral surface, each being exposed to the same pressure, however, they are limited to valves which rotate only through a limited arc of rotation. Other valves which rotate provide balancing grooves around portions of the peripheral surface but do not provide any control for the pressure that migrates axially in both directions along the peripheral surface of the rotor. In the subject arrangement, pressure fields of a predetermined size are located on a peripheral surface of a rotor circumscribing first and second outlet ports which open to opposite sides of the rotor. The size of the pressure fields is determined by the relationship of the diametrical clearance between the rotor and a bore with respect to the operating pressure of the system. This arrangement ensures that the differential forces acting on opposite sides of the rotor are minimized thus eliminating rotor sticking.

摘要： A fluid control valve assembly controls the flow of actuation fluid to and from a fuel injector. The fluid control valve assembly includes at least one solenoid actuator attached to a valve body. The solenoid actuator includes a stator and an armature comprised of a soft magnetic material. At least one of the armature and the stator include an impact surface. The impact surface is coated with a relatively hard, nonmagnetic material coating. Thus, the relatively hard, nonmagnetic material coating will protect the relatively soft, magnetic material comprising the stator and the armature, and increase the durability of the solenoid actuator and the fluid control valve assembly.

摘要： A control system adapted to control an actuator between extended and retracted positions has a fluid control valve connected to the actuator a source of high pressure fluid and a reservoir. The fluid control valve is movable between a first position at which the actuator is connected back to the fluid reservoir adapted and a second position operable to connect the actuator to a high pressure actuation fluid source. An electronic control module is connected in control communication with the fluid control valve and adapted to automatically generate a control signal to position the control valve at the second position in response to an elapsed time being passed at which the fluid control valve is at the first position is greater than a predetermined time.

摘要： The present invention finds application in hydraulically actuated valves, such as gas exchange valves, having a valve member that moves within a valve body between an open position and a closed position. In valves such as these, the valve member typically includes a valve surface that contacts a valve seat included on the valve body when moving to its closed position. However, the impact velocity when the valve surface contacts the valve seat can be quite high. This can lead to fatigue of the valve stem and can wear out the valve seat, both of which can shorten the effective life of the valve. Therefore, the present invention includes a hydraulic pulse generator for slowing movement of the valve member which includes the direction of a hydraulic pulse toward the valve member as the valve member moves from its open position to its closed position.

摘要： A structure and method for electronically minimizing or eliminating performance variation of an apparatus controllable by a control signal, such as an electronically-controlled fuel injector, is disclosed. The method includes the steps of measuring the resultant characteristics of the apparatus at a plurality of operating conditions, such as timing and delivery characteristics of the fuel injector, adjusting the control signal as a function of the measured resultant characteristics, such as by adjusting a base timing and duration or pulse width of a fuel delivery command signal for a fuel injector, and controlling the apparatus in accordance with the adjusted control signal to reduce performance variation. A structure is disclosed to compensate or trim for individual injector variation, includes an electronic control module having a memory for storing trim signals for each injector, the trim signals being derived from observed performance parameter values taken at a plurality of operating conditions, a plurality of sensors for detecting at least one, and preferably a plurality of operating parameters and generating a respective one, and preferably a plurality of, operating parameter signals, and a means for communicating the trim signals to the memory. The electronic control module adjusts a base fuel delivery signal for each injector as a function of the trim data signals for each injector.

摘要： A method of engine compression release braking includes an initial step of compressing gas in an engine cylinder. A compression release brake valve is then opened at least in part by fluidly connecting a brake actuator to a source of high pressure actuation fluid. Next, a valve closing timing that results a valve seating velocity that is less than a pre-determined velocity is determined. The compression release brake valve is then closed at the valve closing timing at least in part by fluidly connecting the brake actuator to a low pressure actuation fluid reservoir.
