Abstract (en)
[origin: WO02090765A1] The invention relates to a fuel injector for injecting fuel in the combustion chamber of a combustion engine. Said injector comprises a body (2) having a body bore (8) in which a first 3/2 control valve (6) is located, said valve body (7) comprising a sliding part (18) and having a seat diameter (11). The valve body (7) of said 3/2 control valve (6) is driven by an actuator (40) directly or indirectly through translation elements (3, 4). A valve member (30) of another control valve (29) is forcibly driven by means of the valve body (7) of said 3/2 control valve (6) through a transmission element (26). When the valve body (7) is in a first position inside the body bore (8), the transmission element (26) is located at a distance h1 (25) from said valve body (7).
