Patent ID: 8910611

Claim:
A fluid delivery system comprising: a first component having a surface and a pair of first walls extending outwardly from said surface; and a second component having a surface facing said surface of said first component, said second component having a pair of second walls and a pair of inner walls positioned between said pair of second walls, said pair of second walls and said pair of inner walls extending outwardly from said surface of said second component; each one of said pair of second walls is welded to a corresponding one of said pair of first walls at primary weld joints, said pair of inner walls sealingly contacts said surface of said first component to define a fluid passage therebetween and a pair of cavities, one of said pair of cavities positioned on either side of said fluid passage; wherein distal ends of each of said pair of inner walls are vibrationally welded to said surface of said first component to form secondary weld joints, and wherein a penetration depth of each of said primary weld joints is greater than a penetration depth of each of said secondary weld joints.
