Isolated cover with independent sealing system

A vibration isolation or noise attenuation and fluid sealing system, for use in connection with internal combustion engine components. For example, for use in the mounting of a valve cover or rocker arm cover upon a cylinder block or cylinder head, or for the mounting of an oil pan cover upon an oil pan housing. The system has an isolation medium or member mechanically and/or chemically bonded to a peripheral flange portion of the cover member. A sealing flange member is chemically and/or mechanically bonded to the isolation member or medium. The three components being a one-piece unitary cover assembly. The fluid leakage along the interfaces defined between the three components is effectively eliminated. The one-piece assembly is secured to the cylinder block or head, or the oil pan housing, by shoulder bolt fasteners. The fasteners exert compressive forces upon the isolation member so as to vary the stiffness and frequency characteristics thereof. Thus, fine tuning of the stiffness can effectively absorb, dampen, and dissipate noise and vibration.

Manufacture of an acoustic silencer

A method for manufacturing a resonator is disclosed in which a sleeve insert is placed into a fixture within a blow molding apparatus. The sleeve insert has a wall with a first plurality of apertures in the wall at a first axial distance and a second plurality of apertures in the wall at a second axial distance. A parison is slid over the sleeve insert; the mold is clamped over the parison causing the parison to press into the sleeve insert at three locations: near the ends of the sleeve insert and at a location between the pluralities of apertures; and air is blown into the sleeve insert, via a blow pin, to expand the parison into the walls of the mold to form cavities proximate the first and second pluralities of aperatures. After cooling, the mold opens to release the newly formed resonator.
