Grommet and Seal Assembly for Cooling Pipes Passing Through Sound Wall

摘要

A grommet and seal assembly enables a pair of ducts to pass through a sound wall that separates an engine from a cooling system. The disclosed grommet and seal assembly enables the sound wall to flex without breaking the seal between the grommets and the air ducts. The grommet and seal assembly may include a pair of flexible grommets which are installed in openings in the sound wall and through which the air ducts are installed. Rigid proximal and distal plates may then be coupled together so that the flexible grommets are sandwiched between the proximal and distal plates. Each flexible grommet may include dual flanges and all four flanges may be sandwiched between the proximal and distal plates after the proximal and distal plates are coupled together. A center plate may also be included between the flanges and between the proximal and distal plates for additional structural integrity.
