초록

A fuel injector which has a double solenoid three-way or four-way spool valve that controls the flow of a working fluid that is used to move an intensifier piston of the injector.

대표청구항 ▼

An upper fuel injector unit coupled to a lower fuel injector unit that has a nozzle coupled to a fuel port that receives a fuel, comprising: a housing that has a supply working port and a return working port for receiving and releasing a working fluid; an intensifier that moves between a return position and a power position, wherein said intensifier increases a fuel pressure to the nozzle when in the power position, said intensifier being adjacent to a first intensifier chamber and a second intensifier chamber; a valve housing; a spool that is located within said valve housing and moves between a first position and a second position wherein an end of said spool is in contact with said valve housing when said spool is in said first or second position, said spool being operatively connected to said working fluid ports and said intensifier chambers so that said first intensifier chamber is in fluid communication with said supply working port and said second intensifier chamber is in fluid communication with said return working port when said spool is in said first position, wherein said first intensifier chamber is pressurized and said intensifier moves to the return position, and said first intensifier chamber is in fluid communication with said return working port and said second intensifier chamber is in fluid communication with said supply working port when said spool is in said second position, wherein said second intensifier chamber is pressurized and said intensifier moves to the power position; a first solenoid that can be energized to move said spool from said second position to said first position; and, a second solenoid that can be energized to move said spool from said first position to said second position, wherein said valve housing and said spool are constructed from a material with enough residual magnetism to maintain said spool position when said solenoids are de-energized and allows said spool end to be separated from said valve housing when said solenoid is energized.
