摘要： The valve comprises a shutter for the drain conduit of the control chamber of the injector; and an electromagnet having a fixed core with a seat for a coil which is energized to operate the armature controlling the shutter.The core presents two coaxial annular pole pieces, the outer one of which is shorter than the inner one and fitted with a ring of magnetic material partially closing the seat and enabling a substantial reduction in the diameter and, hence, the hydraulic resistance and mass of the armature.

摘要： The present invention relates to a fuel injection arrangement for a diesel type engine configured to use carbonaceous aqueous slurry fuels. The fuel injection arrangement includes an injector nozzle for injecting fuel into a combustion chamber; a pump chamber housing a fuel pumping element for generating a pressurised fuel flow to the injector nozzle along an injection path between the pumping element and the injector nozzle; and a check valve connected to a fuel supply for regulating and supplying fuel to the injection path via a check valve outlet. A region immediately downstream of the check valve outlet defines an outlet region and the check valve is arranged to expose the outlet region to the pressurised fuel flow to facilitate flushing of the outlet region during fuel flow between the pumping element and the injector nozzle.

摘要： A pressure control valve for a high-pressure accumulator of an injection device of an internal combustion engine, includes a magnetic actuator. The magnetic actuator has a magnetic core with contacting pins and a magnetic armature with an armature plate. The contacting pins pass through feedthroughs formed in the armature plate. The armature plate is hydraulically connected by a pressure equalization channel to a valve chamber connected to low pressure. The pressure equalization channel has an opening on the magnetic core end face which opens into the armature space. At least one of the feedthroughs forms a passage for the fuel through the armature plate for the pressure equalization. A residual air gap disk is arranged between the magnetic core and the armature plate. The residual air gap disk forms an additional feedthrough with a radial extension that extends in the direction of the opening.

摘要： In a fuel injection valve used for an internal combustion engine, a valve closing lag time due to fluid resistance in a fuel path is shortened to decrease a minimum injection limit. More specifically, in the fuel injection valve in which an anchor is attracted to an end face part of a stationary core having a fuel path formed at a center part thereof by means of electromagnetic force, and in which a fuel injection hole is opened and closed by controlling a valve disc driven in conjunction with the anchor, there are provided a fuel reservoir part at a center part of an upper end face part of the anchor, a through hole extending axially in a fashion that an end part thereof is open to the fuel reservoir part, and a fuel path extending radially outward from the fuel reservoir part so that fuel is fed to a magnetic attraction gap between an upper end face part of the anchor and a lower end face part of the stationary core. Further, an opening part of a through hole that is open to an upper end face part of the anchor is at least partially opposed to a fuel introduction bore formed in the stationary core, and on the opening part of the through hole, a fuel introduction part is provided for capturing fuel running radially outward from a center side part of the anchor and for guiding the fuel thus captured to the through hole.

摘要： In relation to injectors used for internal-combustion engines, it is important to decrease valve closing delay time and also the minimum injection quantity, while these are affected by remanent magnetism in the fixed core, surface tension of the fuel, etc. With reference to a fuel injection valve with a pipe-shaped member to enclose a fixed core and a movable part and further with coils and yokes to cover up the above pipe-shaped member, the anchor to drive the movable member has a plurality of through holes for fuel passage extending in the axial direction, while these through holes are arranged at a certain intervals in the circumferential direction, and projections formed to constitute a contacting surface to touch the fixed core arranged randomly in between the through holes.

摘要： In an electromagnetic fuel injection valve in which a valve assembly formed by integrally connecting a valve element and a movable core to each other is contained in a valve housing, and a first journal part and a second journal part are provided in the valve assembly so as to be supported slidably in the guide hole in a valve housing, the outside surface of the first journal part (21) is formed by a sliding surface (45) slidable on the inside surface of the guide hole (14) and a pair of tapered tilt surfaces (46, 47) connecting to both the front and rear sides of the sliding surface (45); at least the tilt surface (47) on the movable core side, of both the tilt surfaces (46, 47), is formed of a first tilt surface part (47a) connecting to an end part of the sliding surface (45) and a second tilt surface part (47b) connecting to the first tilt surface part (47a); and an angle that the first tilt surface part (47a) makes with a plane perpendicular to the axis line of a valve shaft part (19b) is set larger than an angle that the second tilt surface part (47b) makes with the plane. Whereby a decrease in initial fitting property and an increase in abrasion loss can be avoided, and the weight of the valve assembly can be reduced while good response and flow characteristic are maintained.

摘要： The invention relates to an electromagnetically actuatable valve, which serves in particular to inject fuel into the intake tube of mixture-compressing internal combustion engines having externally supplied ignition. The valve includes a flat armature which is firmly connected with a movable valve member which cooperates with a fixed valve seat and embodied as a ball element. The flat armature is pivotably supported on its side remote from the valve seat or on the side oriented toward the valve seat on a spring tongue preferably embodied out of a remnant air disc. The one-sided fixation of the flat armature on the spring tongue assures an unequivocal up-or-down movement of the flat armature.
