The base portion is configured to be fixed to a casing of the electric compressor. The first and second weight portions are oscillatable relative to the base portion.
Claims10
A damper device for a rotating machine, which includes a rotatable arrangement that is rotatable about a central axis, the damper device comprising:
- a base portion that is configured to be fixed to a casing of the rotating machine;
- a first inertial body that is movable relative to the base portion;
- a second inertial body that is movable relative to the base portion;
- at least one primary connecting member that connects between the base portion and the first inertial body and enables oscillation of the first inertial body in a first direction that is perpendicular to the central axis;
- and
- at least one secondary connecting member that connects between the base portion and the second inertial body and enables oscillation of the second inertial body in a second direction that is perpendicular to the central axis and is different from the first direction.
