发明名称 Aircraft Door Dampening System
摘要 A method and apparatus for dampening a structure in an aircraft. The apparatus comprises a housing, a first compartment located along an axis extending centrally through the housing, a second compartment located adjacent to the first compartment on the axis extending centrally through the housing, a first piston, a rod, and a second piston. The housing has an elongate shape. The first piston is located within the first compartment of the housing. The first piston defines a first chamber and a second chamber of the first compartment as the first piston moves within the housing. The rod is associated with the first piston and extends centrally through the first compartment and the second compartment. The second piston is coaxial to the first piston and located within the second compartment. The second piston moves relative to the rod to accommodate a flow of a fluid into the second compartment.
