ABSTRACT:
The fuel injector includes an injection pump element with electromagnetically actuated control valve body supported therein for the control of the beginning of delivery and the quantity delivered. The injection pump element and the control valve are individually replaceable and the control valve body seats without recoil. A control valve (2), which is arranged with clearance in a stepped hole (19) in a plunger bushing (5) is supported in sealing elements (20). The freedom from recoil is achieved by adaptation of a minimum clearance (46) between an anchor plate (30) and an electromagnetic adjusting device (7), the anchor plate (30) being situated in a liquid-filled damping space (33) and the minimum clearance (46) being optimized as a function of the mass of the moving parts of the control valve (2), the spring stiffness of the control valve seat (25), the geometry of an anchor plate (30) and the viscosity of the fuel in the service temperature range.
