High pressure control valve for a fuel injection system

摘要

A high pressure control valve according to the present invention provides effective and predictable control of a timing fluid and injection fuel metering system of an internal combustion engine. The control valve includes an armature that abuts against a majority of the surface of a valve element to help minimize beating problems. In addition, a compliant web means provides a flexing motion when the valve element seats with a valve seal to mitigate problems of seat beating. Furthermore, the present invention reduces the number of parts of the control valve to achieve simplicity in structure and lower costs, including eliminating the need for a valve stop pin.
