Abstract: Check valves (500) are incorporated into a fuel injector so as to form a controlling orifice in the system between the solenoid vales which direct fuel to the respective injection and timing chambers of the fuel injector and the chambers themselves. The precision fuel metering capability of the valve (500) is determined by an annular clearance created between the plunger (512) of the valve and the valve body (510) when the valve is in its maximum stroke. For achieving a bi-stable operation of the valve, the ratio of the plunger valve seat (510d) area to the maximum plunger valve (512b) area and the spring (514) are key parameters. The check valves (500) are formed as cartridge type check valves that can be calibrated outside of the injector prior to the installation thereof.

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: The improved needle controlled common rail fuel system of the present invention includes split common rails serving respective sets of unit injectors. Each unit injector includes a mechanically actuated plunger reciprocally mounted to cyclically create gradual periods of increasing pressure in the common rail during the advancement stroke of the plunger followed by respective periods of decreasing pressure during the plunger's retraction stroke. The fuel injectors include a pressure control valve for controlling the amount of fuel pressurized by the plunger and a needle valve control device including an injection control valve for creating an injection event during a pumping event by controlling the fuel flow to drain so as to control the fuel pressure forces acting on an injector needle valve element. A flow limiting device is provided to limit the fuel flow from a control volume to drain during an injection event thus reducing parasitic losses while maintaining quick valve closing. In addition, a pressure energy recuperation means is provided which utilizes the pressure of the fuel in each injector's pressure chamber as a result of the pressure energy stored in the fuel to assist in retraction of the injector plunger during each pumping event.

Abstract: 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.

Abstract: An apparatus, system, and method are disclosed for intermittently delivering fluid. An injector intermittently delivers a first quantity of fluid over a first time interval. In one embodiment, the injector is passively cooled. In a certain embodiment, the injector delivers the first quantity of fluid responsive to a fluid flow measurement of a flow meter. An orifice diverts the first quantity of fluid from a primary fluid supply system over a second time interval without decreasing the supply of fluid to a primary load within a flow rate range while the fluid pressure remains within a pressure range. An accumulator accumulates at the least the first quantity of fluid as a fluid charge with positive energy.

Abstract: The improved solenoid actuator assembly of the present invention includes a solenoid stator assembly positioned in an actuator housing and a flux dissipation reducing feature which minimizes flux leakage into the housing thereby maximizing the attractive force and minimizing the response time. The flux dissipation reducing feature includes a slot formed in the housing adjacent each outer face of the solenoid stator pole pieces thereby avoiding a metallic housing wall into which leakage may occur. The slots also permit the cross sectional area of the pole pieces to be maximized thereby increasing the available attractive force. The solenoid stator assembly requires only a single housing which functions to directly support the laminate stack assembly without an intermediate housing while also functioning as an injector body component subject to the compressive assembly load of the injector and including high pressure fuel passages. As a result, the present solenoid actuator assembly is compact, inexpensive and functions to optimally maximize attractive forces while reducing response time.
