Abstract
The damper (12) includes first (14) and second (16) damping elements which are arranged in parallel by means of a connection disc (20). The first damping elements (14) comprise at least one first group (24) of resilient units (22) including at least two first resilient units (22) arranged in series by means of a first intermediate support element (26), and the second damping element (16) comprise at least one second group (34) of resilient units (32) comprising at least two second resilient units (32) arranged in series by means of a second intermediate support element (36). The damper includes at least one annular unit (39) for phasing of the resilient units (22, 32), which is distinct from the connection disc (20) and bears both the first (26) and second (36) intermediate support elements.
