    Abstract: The present invention relates to a control valve (113; 113') for a fuel injector (101). The control valve (113; 113') has a control valve body (115; 115') which defines a supply passage (133; 133') for high pressure fuel. A control chamber (119; 119') and a pressure compensating chamber (143; 143') are provided in the control valve (113; 113'). The control chamber (119; 119') and the pressure compensating chamber (143; 143') are both in fluid communication with the supply passage (133; 133'). A control valve member (117; 117') is provided for controlling fuel pressure in the control chamber (119; 119'). The pressure compensating chamber (143; 143') is spaced radially outwardly from the control chamber (119; 119'). The invention also relates to a control valve member (117') having a pressure compensating cavity (159).

    Abstract: A connector arrangement for a fluid system, comprising a component (40), more particularly being an automotive fuel injector, that defines a first fluid passage (64) having a connector (68), a pipe (68) that is engageable with the connector (68) of the first fluid passage (64), preferably to form a high pressure seal, and connecting means (74) arranged to connect the pipe (68) to the connector (68) of the first fluid passage (64). A chamber (88) is defined between the connecting means (74) and the component (40), such chamber serving to collect leaked fluid from the first fluid passage (64). The first component is provided with a second fluid passage (100) having a first end in communication with the chamber (88) and a second end in communication with a low pressure drain such that leaked fuel is provided with a drain path. The invention is also applicable to other components which are supplied with fluid from a pipe, or which supply fluid to a pipe, and for which potential leakages must be managed appropriately.
