The vibration-equaliser filled with fluid incorporates a connection (111) joined to a vibrating body, such as an engine. A holder (112) forms an expandable and retractable chamber (119) for auxilairy fluid. An elastomeric part (113) with reinforcement (114) joins the connection (111) and the holder (112) and all three together form a chamber (118) for the main fluid.The auxilairy and main fluid chambers are separated by a between-wall (116) and incorporates a control for the through-flow (117)
