Abstract
The invention relates to an oil sump damped against structure-borne noise. Since higher requirements are being made of the reduction in the emission of noise from internal combustion engines, the invention proposes to surround the oil sump (1) with a sump cover (7), the sump cover being made of a single or multiple layer of plastics or steel sheet. To avoid sound bridges, the oil sump (1) and the sump cover (7) are separated by elastomeric elements (9, 11, 14, 22, 23, 32). The sump cover provides an economical means of increasing the noise damping. A sump cover can also be retrofitted to engines.
