Patent ID: 7877877

Claim:
A method for manufacturing a solid valve housing for an electromagnetically operable valve, wherein the housing has at least three zones, two directly adjacent ones of the zones having different magnetic properties, the method comprising: providing at least three flat sheet metal plates side by side, each having different magnetic properties directly adjacent to the others; joining the at least three sheet metal plates at directly adjacent bordering edges to form a sheet metal section; shaping the sheet metal section into a sleeve shape; joining together the bordering edges, which are now opposite one another and run in a longitudinal direction of the sleeve, to form a sleeve blank; and final machining the sleeve blank until a desired geometry of the housing is achieved; wherein two outer ones of the sheet metal plates are made of a magnetic material, and a middle one of the sheet metal plates between the two outer ones of the sheet metal plates is made of a nonmagnetic material.
