摘要 |
A two-way needle control valve for controlling the position of the needle of a needle valve in a fuel injector is disclosed. A poppet member configured for displacement between an open position and a closed position in a valve bore of a valve body. The valve bore includes drain for draining fuel from valve when valve is open. The valve includes a supply line that extends across at least a portion of the valve body. The supply line receives fuel from a high pressure fuel line. An inlet throttle line is in fluid communication with the supply line, and delivers fuel from the supply line to a control chamber in a throttle plate. An outlet throttle line delivers fuel from the control chamber to a valve body inlet line, which is configured to deliver fuel to the cavity in the valve bore.
