a damping assembly for a pivoting stowage bin includes a rotary hydraulic damper that is mounted on the pivot axis of the stowage bin . the rotary hydraulic damper includes a damper body that receives a rotor having at least one vane moved through contained hydraulic fluid . preferably , an exterior bearing surface on the damper precludes the active damping elements from radial loads , while a distributed attachment of the rotor to the pivoting bin enables reduced torque loads . the damper can include an integrated flow - control valve for controlling the opening rate of the pivoting bin as well as an integrated mechanical stop for the bin .
