Valve for metering a flowing medium

Abstract

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.
