Abstract
The invention relates to a damping and holding device having a rigid base (7), a rigid ring (9), a truncated cone shaped resilient wall (12) resisting axial compression and sealingly connecting the base to the ring, a flexible membrane (13) sealingly connected to the ring, a sealing dividing wall (14) connected to the ring between the truncated cone shaped wall and the membrane, a restricted passage (15) providing communication between the two sides of the dividing wall and a liquid mass (16) filling the case thus formed. The device further comprises a second truncated cone shaped resilient wall (17) resisting axial compression and oriented in a direction opposite that of the first one (12), the small bases of the two truncated cone shaped walls being juxtaposed axially and both secured to the base, and a rigid external framework (18) connecting the large base of the second rigid wall with the ring.
