摘要： A valve body for a fluid injector includes a central longitudinal axis and a one-piece base body. The base body has a side wall defining a recess extending from a fluid inlet side to a fluid outlet side of the base body. The side wall has a thin portion having a decreased wall thickness relative to further portions of the side wall that adjoin the thin portion along the longitudinal direction towards the fluid inlet side and the fluid outlet side. The valve body includes a metallic reinforcement jacket that is rigidly coupled to the base body and which axially overlaps the thin portion having the decreased wall thickness.

摘要： The invention relates to a fuel injector having an electromagnet 2 which contains a magnet core 6 and a coil 7 and which further has an armature 9 that is guided on an armature pin 8. The armature pin 8 is guided in a guide sleeve 11 which projects into the electromagnet 2. The fuel injector further has an injector body 4 with at least one injection opening which is introduced into the injector body 4 and which is controlled by an injector needle 5. The aim of the invention is to provide a fuel injector which is functionally improved with respect to the switching times of the fuel injector and the forces that can be generated in the fuel injector while simultaneously simplifying a guide sleeve for an armature pin. This is achieved in that the guide sleeve 11 is integrated into the magnet core 6 and is connected to the magnet core 6 in a formfitting or bonded manner. For this purpose, the guide sleeve 11 has widened sections 16 at both ends, said widened sections fixing the guide sleeve 11 in the magnet core 6.

摘要： High-response and high-power electromagnetically driven flow rate control valve with flange portion forming an attracting surface on an anchor, a first peripheral surface portion having a diameter smaller than the flange portion, and a cylindrical non-magnetic area opposing an outer peripheral surface of the flange portion with a third clearance interposed therebetween are provided, and a first fluid trap portion communicating with the back pressure chamber via the third clearance is provided. When the diameter of the flange portion is enlarged in order to enlarge the cross-sectional area of the attracting surface, fuel that is displaced by the anchor is increased, but is partly absorbed in the first fluid trap portion, so that the fuel passing through the fuel channel does not increase in comparison with fuel before the diameter of the flange portion is enlarged. Accordingly, the cross-sectional area of the attracting surface may be enlarged.

摘要： The metering valve has a shutter for a discharge conduit, and an electromagnet for controlling an armature disconnected from a relative stem and sliding along the stem by means of a sleeve. The armature is secured to the stem by a shoulder of the armature cooperating with a C-shaped ring fitted to the stem. A plate is interposed between the sleeve of the armature and a ring nut to reduce the overtravel of the armature, is locked transversely by a support of the electromagnet, and is kept resting on the ring nut by a compression spring. To secure the armature to the stem, the plate has an opening which is ineffective in reducing overtravel when the plate is moved transversely with respect to the armature.

摘要： A valve body for an electromechanically operable valve is produced by providing a base element with a circumferential sidewall having a first portion, a second portion, and a third portion, the sidewall being made of a ferromagnetic material and enclosing a cavity extending along a longitudinal axis. The third portion is positioned in longitudinal direction between the first portion and the second portion. A thickness of the third portion is smaller than a thickness of the first portion and the second portion. Hardening the third portion is achieved by laser heating, which transforms a material structure of the third portion into a martensitic structure. The locally decreased thickness creates a bottleneck for a magnetic flux, and a magnetic flux bypass in the valve body is reduced due to magnetic saturation; however, a structural resistance of the valve body remains high due to the laser induced hardening.
