摘要： A control valve (16) of a fuel injector is provided with a cylindrical valve body (42) extending along a main axis from an upper face (44) to a lower face (46), said body (42) being provided with a large cylindrical shallow recess (48) opening in said upper face (44) and in the bottom of which opens a valve distributor bore (50) axially extending toward the lower face (46). The control valve further has a magnetic armature-stem assembly (62) and, guiding means (56) for slidably guiding the armature-stem assembly (62) into the valve bore (50) and with seating means (70, 72, 74), distinct and independent means from the guiding means (56), for opening or closing a fluid communication between a high pressure conduit (112) and a return conduit (110), both conduits opening in said bore (50).

摘要： The invention relates to a control valve for a control chamber of a fuel injector, which valve includes a body (34) provided with a bore (36); a generally cylindrical jacket (38) inserted into the bore (36) and including an axial passage (40), a cross-section of which defines an inner fuel passage (44) with a sealing seat (50); a sealing rod (42) sliding axially inside the jacket (38) and configured to enable or prevent the flow of fuel downstream from the seat (50), the sealing rod (42) including an actuating end (48) for connecting to an actuating device (28) outside of the jacket. An annular compensation chamber (52) surrounds the jacket (38). The inner fuel passage (44) has an outlet opening (48) located downstream from the sealing seat (50) in the jacket portion opposite the actuating end (48) of the sealing rod (42).
