Damping support for the suspension of an oscillating body on a support structure, particularly for the suspension of the engine on the chassis of a motor vehicle

A damping support for the suspension of an oscillating body on a support structure, comprising:

• a tubular support body which is intended to be fixed to the support structure and is closed at one end so as to define a chamber for containing a damping liquid,
• an attachment member which is intended to be fixed to the oscillating member and is connected coaxially to the other end of the tubular support body,
• an annular element of elastomeric material whose outer surface is fixed to the tubular support body and whose inner surface is fixed to the attachment member to effect the coaxial connection of the attachment member to the other end of the tubular support body, and
• fluido-dynamic means for damping the oscillations of the attachment member relative to the tubular support body, including a transverse disc member rigidly connected to the attachment member and intended to be immersed in the damping liquid,
• wherein the disc member defines at least one aperture for the passage of the damping liquid and obturator means are associated with the disc for varying the area for passage of the damping liquid through the at least one aperture.
