Abstract
The present invention relates to a control valve for a fuel injector. The control valve has a control valve body which defines a supply passage for high pressure fuel. A control chamber and a pressure compensating chamber are provided in the control valve. The control chamber and the pressure compensating chamber are both in fluid communication with the supply passage. A control valve member is provided for controlling fuel pressure in the control chamber. The pressure compensating chamber is spaced radially outwardly from the control chamber. The invention also relates to a control valve member having a pressure compensating cavity.
