摘要： A reverse flow valve member is positioned within an injector body of a fuel injector and is movable between a closed position and an open position. When the reverse flow valve member is in its closed position, an upper portion of a nozzle supply passage is blocked from fluid communication with a lower portion of the nozzle supply passage. A compressed spring biases the reverse flow valve member to its closed position. When the reverse flow valve member is in its open position, the fuel pressurization chamber is fluidly connected to the lower portion of the nozzle supply passage. The present invention limits gas ingestion due to tip leakage, and allows an injector with trapped gas to prime itself.

摘要： A fuel injector with a direct control needle valve has a closing hydraulic surface exposed to a control fluid, and an opening hydraulic surface exposed to fuel. The control fluid is different from the fuel. A vented annulus is positioned around the needle valve member between the control fluid chamber and the fuel chamber. An o-ring is positioned in a lower pressure region between the annulus and the control fluid chamber.

摘要： Starting and ending an injection event are accomplished by respectively energizing and de-energizing a solenoid actuator to move an armature assembly with respect to a stator. The stator is protected from impact damage by maintaining the armature assembly out of contact with the stator. The inducement of residual magnetism in the armature assembly is reduced by stopping the armature assembly at a large radius outside of the magnetic flux circuit through the stator and soft magnetic armature of the armature assembly, when the solenoid actuator is energized.
摘要翻译：通过分别对螺线管致动器通电和断电以相对于定子移动电枢组件来实现启动和结束喷射事件。通过保持电枢组件与定子不接触，保护定子免受冲击损坏。当螺线管执行器通电时，通过电枢组件的定子和软磁衔铁将电枢组件停在磁通回路外部的大半径处，可以减少电枢组件中剩余磁力的诱导。

摘要： An electromagnetic control valve is provided. The control valve includes a housing defining a bore and a fluid passageway having a seat. A valve element is slidably disposed in the bore and is moveable between a first position where a flow of fluid passes by the seat and a second position where a flow of fluid relative to the seat is blocked. A solenoid having an armature is operatively connected with the valve element. The solenoid is operable to move the valve element from the first position to the second position. A biasing assembly is operatively engaged with the valve element and is adapted to move the valve element from the second position towards the first position. The biasing assembly exerts a first force on the valve element during a first predetermined travel distance from the second position and a second force on the valve element during a second predetermined travel distance. The first force is greater than the second force.

摘要： A fuel injector pressurizes fuel in a pressurization chamber and ejects the fuel from an orifice. A reverse flow check valve allows fluid communication between the pressurization chamber and the orifice during fuel injection, but blocks fluid communication between the pressurization chamber and the orifice when fuel pressure in the pressurization chamber decreases.
