Abstract

The support is particularly compact, simple in construction and very reliable in operation. It comprises a main composite unit (1) comprising a first fixing element (3) and a mass of elastic material (2), this mass forming, on one hand, a massive portion (6) of a roughly frusto-conical general shape disposed between the first fixing element (3), part of this main unit between the two armatures (4, 5) being gripped between a housing (8) and a cover (9) fixed to each other and constituting a second fixing element. The housing defines with the elastic mass a work chamber (11), an expansion chamber (12) and a communication passageway (13) interconnecting with the chambers.
