Fluid delivery system and method of forming fluid delivery system

An oil shower delivery system for an internal combustion engine, said oil delivery system comprising:

• a shower plate formed of a plastic material, said shower plate having an interior surface and an opposite exterior surface, said shower plate having a pair of first walls extending outwardly from said interior surface, said shower plate having an inlet and at least one outlet extending between said interior surface and said exterior surface;
• and
• a baffle plate formed of a plastic material, said baffle plate having an interior surface and an opposite exterior surface, said interior surface of said baffle plate facing said interior surface of said shower plate, said baffle plate 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 interior surface of said baffle plate,
• each one of said pair of second walls is vibrationally welded to a corresponding one of said pair of first walls to form primary weld joints, a distal end of each of said pair of inner walls are vibrationally welded to said interior surface of said shower plate to form secondary weld joints that define a fluid passage therebetween and a pair of cavities, one of said pair of cavities positioned on either side of said fluid passage, said vibrationally welding of said pair of first walls and said pair of second walls to form said primary weld joints produces a weld flash, said weld flash is contained within said pair of cavities to prevent said weld flash from entering said oil passage, said oil passage in fluid communication with said inlet and said at least one outlet,
• wherein said pair of inner walls have a length that is greater than a length of each of said pair of first walls and said pair of second walls.

A method for forming a fluid delivery system, said method comprising:

• providing a first component formed of a plastic material, said first component having a surface and a pair of first walls extending outwardly from said surface;
• providing a second component formed of a plastic material, said 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, said pair of second walls extending outwardly from said surface of said second component, said pair of inner walls extending outwardly from said surface between said pair of second walls;
• and
• vibrationally welding said first component to said second component such that each one of said pair of second walls and a corresponding one of said pair of first walls are bonded at primary weld joints, and said pair of inner walls are bonded to said first surface at a secondary weld joint so as to define a fluid passage between said pair of inner walls and a pair of cavities, each one of said pair of cavities positioned on each side of said fluid passage,
• wherein a penetration depth of said primary weld joint is greater than a penetration depth of said secondary weld joint.

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 primary weld joints bounding a perimeter of said pair of inner wall, 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.
