ABSTRACT:
A circular metal clinch ring (36) secures a cap (26) to a shell (24) of an EEGR valve (20). The clinch ring has a plurality of integral sharp pointed barbs (210) that partially embed in polymeric material of the cap. The ring constrains the shell and cap against relative axial and circumferential movement, with some barbs being pointed in one sense and others in the opposite sense to resist relative circumferential movement between the cap and the shell in both circumferential senses. A wave spring washer (186) is disposed to maintain the axial position of the bobbin-mounted solenoid coil (70) within the valve.
