Abstract
The present invention relates to a damping device of the type comprising a housing (40) defining a sealed chamber (42) containing a viscous damping fluid such as silicone and receiving a blade capable of displacement relative to the housing. In accordance with the invention, the housing (40) and the blade (80) comprise respective series of fins (50, 51, 52, 53 and 90, 92, 94, and 96) which are interleaved. Thus, relative displacement of the blade inside the housing (40) is braked by a combination firstly of the controlled flow of fluid from one side of the blade to the other via interstices between the blade and the housing, and secondly by viscous friction between the interleaved fins. The invention also relates to a device for measuring the level of fuel in a motor vehicle fuel tank and including such a damping device.
