Abstract

The assembly has a cylinder case placed above an oil sump, and a sandwich plate (1) interposed between the case and the sump. The plate is fixed, in its periphery, to the case and the sump. The plate is constituted of a central core (1c) placed between a lower sheet (1a) and an upper sheet (1b). The stiffness of the core is 50 times lower than respective stiffness of the sheets. Each sheet comprises a slit permitting a clearance along an axis parallel to width of the plate. The sheets are made of aluminum or steel. The core is made of elastomer.
