  • the invention provides a compact fan shroud receptacle and engine inlet air structure which eliminates the need for space and fastening means for a wide range of separate components in the already crowded engine compartment of today's automobile. It provides substantial cost savings by virtue of having eliminated the need to manufacture and assemble various parts associated with underhood systems, while utilizing heretofore unused surface areas of the fan shroud.
  • the invention may provide a standard or uniform structure which is unaffected by many new vehicular designs. Specifically, the shape of the fluid chambers; air intake conduits; air filter chambers; resonator chambers and the like need not be redesigned each time the fender wells and other interior parts are changed on at least some new vehicle models. Also, the integrally molded windshield washer fluid or headlamp washer fluid compartments may have a larger capacity than the previously employed separate containers.
  • the resultant structure is extremely rigid, both radially and axially, and damped by fluid in the receptacles, reducing vibration or excitation of the fan shroud caused by the rotating fan surrounded thereby, hence diminishing a possible source of bothersome noise.
