    摘要： The invention relates to a valve for metering fluid, having a flow channel (35), which leads from a fluid inlet (13) to a metering opening (17), for the fluid and having a filter device (40), which is arranged in the flow channel (35) and through which the fluid flows. The filter device (40) has a coarse filter (41) and a fine filter (42), which is arranged downstream of the coarse filter (41) in the flow direction of the fluid, in order to increase the robustness of the filter device (40) against damage from larger particles substantially resulting from manufacturing and assembly processes of the fluid system in which the valve is used.

    摘要： The invention relates to a fuel injector (1; 1a; 1b), in particular for compression-ignition internal combustion engines, having a control valve (15) and a control chamber (8), wherein the control chamber (8) is connected via an outflow bore (25) to a valve chamber (16) of the control valve (15), wherein a valve bolt (20) is arranged in the valve chamber (16), wherein the valve bolt (20) is loaded into a closed position by the spring force of a compression spring (30) in a first position, in which closed position said valve bolt (20) interacts with a valve seat surface (41), wherein the compression spring (30) is arranged in a low-pressure region (27) which is sealed with respect to the valve chamber (16), wherein the opening stroke of the valve bolt (20) can be set for a second position, in which the valve bolt (20) is spaced apart from the valve seat surface (41), and wherein the valve bolt (20) is guided in the valve chamber (16) by a sealing sleeve (19) which encloses the valve bolt (20) radially. According to the invention, it is provided that the opening stroke of the valve bolt (20) is brought about by the valve bolt (20) bearing at least indirectly against the sealing sleeve (19).

    摘要： The manufacturing method regards a fuel injector servo valve (5), wherein a bushing (41) is designed to slide on a fixed stem for opening/closing the servo valve (5) and carries an anchor (17), which is free to slide axially on the bushing (41); according to the method, the bushing (41) is provided in such a way that it has a guide portion (61) and an adjacent terminal portion (71); after the anchor (17) has been mounted on the guide portion (61), a ring (73) is fitted on the terminal portion (71) so that it is brought to bear upon an axial shoulder (72) provided between the guide portion (61) and the terminal portion (71); the ring (73) is then welded to the terminal portion (71) via weld material along a circumference, so that a weld is carried out in view without any need for angular positioning between the bushing (41) and the welding device.
