Centrifugal pendulum absorber

A centrifugal pendulum absorber for a flywheel, comprising:

• a plurality of pendulum weights being arranged circumferentially around a center axis of the centrifugal pendulum absorber,
• a plurality of closed compartments which are arranged circumferentially around the center axis, wherein at least one pendulum weight is arranged in each one of the plurality of closed compartments, and
• a ring member extending in a circumferential direction thereof and adapted for being connected to the flywheel,
• wherein a channel for fluid is provided between at least one pair of abutting closed compartments of the plurality of closed compartments, as seen in the circumferential direction, wherein the channel for fluid is at least partly provided in the ring member, and wherein the channel for fluid fluidly connects the at least one pair of abutting closed compartments, wherein the ring member comprises at least one connection portion adapted for connecting the ring member to the flywheel, which at least one connection portion extends radially inwardly towards the center axis between the at least one pair of abutting closed compartments, and wherein the channel for fluid is at least partly provided in the at least one connection portion.
