摘要： A valve for injecting fuel includes a valve carrier having a valve seat and an inflow orifice, a valve positioning member, and a flow limiting element that is disposed on the valve positioning member. The inflow orifice includes a step having a peripheral annular edge, and the flow limiting element is disposed on the valve positioning member in such a way that when the valve is opened, a flow area between the annular edge and the flow limiting element is reduced from a first flow area to a second flow area.

摘要： A valve for metering a flowing medium, e.g., an injection valve for fuel-injection systems of internal combustion engines, is provided. In an embodiment, the valve has a sealing seat formed by a valve seat and a sealing head of a valve member able to be driven to execute lift motions. The valve has a plurality of spray orifices having hole-entry openings situated downstream from the sealing seat and sealable by the sealing seat. The valve has flow-through channels situated upstream from the sealing seat, which extend parallel to each other and discharge in front of the sealing seat. In order to achieve a unified upstream flow approach of all hole-entry openings of the spray orifices, e.g., if the number of spray orifices and flow-through channels differs, an upstream-flow shaper having at least one flow-through opening is situated between sealing seat and hole-entry openings of the spray orifices.

摘要： A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle, which is arranged in a nozzle body, is actuable by an actuator and acted upon by a restoring spring such that a valve closure member, which is in operative connection to the valve needle and faces the combustion chamber, is kept in sealing contact on a valve seat surface in the non-actuated state of the actuator. A surface of the fuel injector has a concave design in a transition region between the nozzle body and the valve-closure member.

摘要： A method for operating an internal combustion engine in which a valve needle of a fuel injector is adjusted from a closing position via an intermediate position to an opening position and back again. The adjustment is carried out with the aid of a piezoelectric actuator to which a trigger signal is applied. To reduce the contamination danger of the fuel injector and to keep wear of the valve needle low, the trigger signal for triggering the piezoelectric actuator has a greater slope steepness during the transition of the valve needle from the closing position to the intermediate position than during the transition of the valve needle from the intermediate position to the opening position.

摘要： A fuel injector for internal combustion engines is provided, which has a valve seat member, bordering a valve chamber, having a valve seat and spray orifices and a central blind-end bore as well as a valve member that is able to be driven to cause a lift motion having a closing head, which, together with a valve seat, forms a sealing seat lying upstream of the spray orifices. In order to prevent an underpressure developing in the blind-end bore in the closing phase of the sealing seat, and a partial return flow of the fuel connected with it, the closing head of the valve member is provided, at its end face facing towards the valve seat member, with a plunger sticking out from closing head, which has a shape adjusted to the contour of the blind-end bore, and dips into the blind-end bore when the sealing seat is closed.

摘要： An injection valve is indicated for internal combustion engines, having a sealing seat formed by a valve seat and a closing head of a valve needle, and having a plurality of spray holes situated downstream from the sealing seat. The spray holes, which are stepped in cross-section, each have at least one upstream hole inlet section having a very small hole cross-section and a hole inlet opening, and a downstream hole outlet section having a very large hole cross-section and a hole outlet opening. In order to prevent unwanted deposition of burnt fuel on the edges of the hole outlet openings, all the hole outlet sections are connected to one another by a groove having a groove opening that points downstream.
