Abstract
A fuel injector comprising a valve needle for controlling fuel injection through an injector outlet, a control chamber for receiving fuel and a three-way control valve that controls fuel pressure within the control chamber to control opening and closing movement of the valve needle to control fuel injection through the outlet. The three-way control valve controls communication between (a) a first passage and a second passage and (b) a third passage and the second passage, and includes a first housing provided with a guide bore for a control valve member, whereby movement of the control valve member is guided within the guide bore and a first valve seat, defined by a second housing, with which an end of the control valve member is engageable to control communication between the first and second passages. The first housing is a control valve housing and the second housing is an injector housing, the injector housing being provided with a guide bore for the valve needle or a part carried by the valve needle. The control valve also defines a second valve seat defined by the first housing with which the control valve member is engageable to control communication between the second and third flow passages, and an intermediate housing located between the first and second housings, wherein the second passage is defined within the intermediate housing.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
