摘要： A dishwasher appliance or pump assembly may include a fluid pump and a vibration damper. The fluid pump may define a center of gravity. The vibration damper may be attached to the fluid pump. The vibration damper may include first and second spring beams and first and second damper masses. The first spring beam may extend longitudinally between a fixed end and a free end and be offset from the center of gravity at a first radial side. The first damper mass may be disposed on the free end of the first spring beam. The second spring beam may extend longitudinally between a fixed and a free end and be offset from the center of gravity at a second radial side. The second damper mass may be disposed on the free end of the second spring beam.
