Title:
回転ダンパを備える義肢装置
Document Type and Number:
Japanese Patent JP6966800
Kind Code:
B2
Abstract:
A prosthesis device has a rotary damper and a displacing device with a magnetorheological fluid in a damper volume of a housing. Two partition units divide the damper volume into two or more variable chambers. The partition units include a partition wall connected with the housing and a partition wall connected with a damper shaft. Radial gaps are formed in the radial direction between the partition wall on the housing and the damper shaft, and between the partition wall on the damper shaft and the housing. An axial gap is formed in the axial direction between the partition unit, the damper shaft and the housing. The magnetic field of the magnetic field source passes through at least two of the gaps.
