| 20100281691 | METHOD FOR MANUFACTURING A SOLID HOUSING - The method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve, is characterized in that the following method steps are used: a) providing a sheet metal strip made of a magnetic or magnetizable material, b) introducing an additive into a middle area of the sheet metal strip and fusing there for forming a non-magnetizable structure, c) cutting the sheet metal strip into a sheet metal piece of desired width, d) deforming the sheet metal piece into a sleeve shape, e) mutual fastening of the cut edges now facing each other and running in the longitudinal direction of the sleeve for forming a sleeve blank, f) final machining of the sleeve blank until a desired geometry of the housing is achieved. The housing is suitable in particular for use in fuel injectors in fuel injector systems of mixture-compressing spark-ignition internal combustion engines. | 11-11-2010 |

| 20090211096 | Method for manufacturing a solid housing - A method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve, includes the following operations or steps: a) providing a base element made of a magnetic or magnetizable material, b) carburizing and/or nitride-hardening of at least one subarea of the base element by diffusion of carbon and/or nitrogen under thermal treatment for forming a non-magnetizable structure in the area of the diffusion zone, and c) finishing the base element so created until an intended geometry of the housing is achieved. The housing is suitable in particular for use in fuel injectors in fuel injector systems of mixture-compressing spark-ignition internal combustion engines. | 08-27-2009 |
| 20100126007 | METHOD FOR PRODUCING A RIGID MAGNETIC CIRCUIT COMPONENT - A method for producing a rigid magnetic circuit component for an electromagnetically operable valve includes: a) providing a base element made of a magnetic or a magnetizable material, b) complete first heat treatment of the base element, c) a local second heat treatment of the base element so as to form a subregion having a microstructure of martensite and residual austenite in the otherwise martensitic base element, and d) installing the finished processed base element as the magnetic circuit component in a magnetic circuit. | 05-27-2010 |
