Hydraulic antivibratory support for engine of vehicle, has obturator element integrated to elastomer body and obturating choked passage, where element is formed of single piece with support and modifies effective section of passage

摘要

The support has an elastomer body (7) for connecting two rigid armatures (1, 2) and delimiting a working chamber (A). The body supports a static load and dampens vibratory movements between the armatures. An elastomer flexible wall (13) delimits a compensation chamber (B), which is filled with fluid and connected to the chamber (A) by a choked passage (15). A rigid partition (14) separates the chambers. An elastomer obturator element (30) is integrated to the body and obturates the passage. The element is formed of single piece with the support and modifies an effective section of the passage.
