摘要： A valve for metering a fluid, the valve preferably being designed as a fuel injector for internal combustion engines. The valve includes an electromagnetic actuator and a valve needle that is actuatable by the actuator. The valve needle is used for actuating a valve closing body that cooperates with a valve seat surface to form a sealing seat. An armature of the actuator includes a through opening through which the valve needle extends. An annular gap is formed between an inner wall of a housing part and an outer side of the armature. A movable damping element that may have a partial ring shape is situated on the annular gap. The movable damping element is actuatable by a magnetic field that is generated by the actuator. The dynamics of the armature may thus be advantageously influenced in order to in particular reduce an armature bounce.

摘要： An object of the present invention is to provide a fuel injection valve configured to suppress bouncing of a valve element that is caused as a result of the valve element being rendered elastic when the valve element collides with a valve seat.The fuel injection valve of the present invention includes the valve element configured to come into contact with the valve seat for closing an injection hole and to separate from the valve seat for unclosing the injection hole, an elastic member urging the valve element toward the valve seat, a movable iron core disposed to be in and out of contact with the valve element, a fixed iron core disposed to be opposed to the movable iron core, and a coil configured to generate electromagnetic force for moving the movable iron core. At least one lower rigidity part having reduced rigidity per axial unit length is provided between a surface where urging force of the elastic member is transmitted to the valve element and a seat part whereat the valve element comes into contact with and separates from the valve seat.

摘要： An injector has an injector body including an injector cavity defining an inner wall and a longitudinal axis, an injector orifice and a plunger slidably disposed within the injector cavity. The plunger has an outer portion and an inner portion at different locations longitudinally along the plunger. The inner portion has a plurality of surface portions including a guiding portion configured to substantially mate with the inner wall of the injector cavity, guide the plunger to slidably move in a direction along the longitudinal axis and substantially prevent the plunger from laterally translating within the injector cavity. The plurality of surface portions also includes a restriction portion configured to form a restrictive cavity between an exterior surface of the inner portion and the inner wall of the injector cavity axially along a length of the inner portion.

摘要： An internal combustion engine direct injection fuel injector system includes a fuel rail which is welded to a fuel rail bracket. A fuel rail mounting sleeve has a flange and is bolted to the engine cylinder head. The bracket fits around the flange and is held in place by a steel washer and a pair of stepped isolator washers which are positioned in pockets formed on either side of the bracket. The isolator washers serve as springs which form a shock absorber between the bracket and cylinder head. Compression forces on the bracket and isolator washers are controlled by bolt tension.

摘要： A valve assembly for an injection valve may include a valve body comprising a cavity with a fluid inlet portion and a fluid outlet, and a valve needle axially movable in the cavity, the valve needle preventing a fluid flow through the fluid outlet in a closing position and releasing the fluid flow through the fluid outlet in further positions, the valve needle comprising a radially extending protrusion and an electro-magnetic actuator unit configured to actuate the valve needle and comprising an armature in the cavity. The armature comprises an armature cavity having a first stop surface and a second stop surface that faces the first stop surface. The protrusion of the valve needle is arranged in the armature cavity axially between the first stop surface and the second stop surface such that a relative movement between the valve needle and the armature in axial direction is limited.
