Abstract
Fluid transmission devices combine and separate fluid flowing therein, and are particularly useful in engine exhaust systems. Given the ever-increasing complexity of exhaust systems, there is a need to reduce construction costs, labor costs, and costs associated with maintaining an inventory of parts. The present fluid transmission device and method of manufacturing comprises a tubular member having a wall, an integral flow redirection member, and an opening. The integral flow redirection member is formed from the wall by cutting a slit in the wall and depressing the wall adjacent the slit until at least a portion of the wall extends within the tubular member. The opening is also formed from depressing the wall. Finally, the flow direction member redirects at least a portion of fluid flow traveling within the tubular member through the opening.
