<p>A method of forming a cup shaped housing member with an integral inlet tube extending radially to the axis of a cup shaped member from a flat strip of metallic material in progressive dies such that a tube is formed first to extend parallel to the axis of the cup shaped member and in subsequent progressive steps is moved first to a position extending at an angle to the axis and finally to a position extending radially to the axis of the cup shaped member.</p> |
