Patent
·
OSTI ID:5331131
A vibration resistant cover for closing an opening extending longitudinally through a cavity defining wall of a housing subject to noise including vibration is described. The wall has an outer face and an inwardly facing peripheral surface about the opening adjacent the face. The cover comprises: a rigid outer rim having a flange operatively engageable with the wall outer face and adapted to be secured thereto, a rigid central panel extending laterally within the rim support position and having an outer portion with a continuous outer edge parallel with, or similar configuration to and longitudinally offset from the inner edge of the rim support portion, and a bead of resilient vibration absorbent elastomer secured to the rim support portion and to the panel outer portion and sealing a peripheral gap between the offset inner and outer edges, the bead further acting to seal and to provide resilient damping between the central panel and the outer rim so as to close the opening and limit the transmission of housing vibrations to the central panel, thereby minimizing the generation of noise by the panel.
