ABSTRACT:
A solenoid operated valve has first flux collector, bobbin with coil and an armature assembled onto a valve body with a tubular housing received over the body and first portions of the housing, in the form of tabs, deformed over the bobbin flange to retain the assembly. A second flux collector with adjustable pole price is then assembled adjacent the bobbin and retained in place by deformation of second portions of the housing. The pole piece is accessible exteriorly for adjustment through the end of the housing.
