专利汇可以提供Temperature compensated adjustable damper unit专利检索，专利查询，专利分析的服务。并且An adjustable damper unit is provided which exerts a restraining torque on a shaft, the torque being directly proportional to the angular velocity of the shaft. Damping is provided by a magnetic restraint on a drag cup driven through the magnetic field of a permanent magnet by planetary gears. An external adjusting ring controls the magnitude of the magnetic restraint and thereby controls the damping rate.，下面是Temperature compensated adjustable damper unit专利的具体信息内容。

权利要求

1. An eddy current damper unit comprising: a housing; an input shaft rotatably mounted in the housing; a further shaft rotatably mounted in the housing, a gear transmission system coupling said input shaft to said further shaft and providing a step-up transmission ratio between said input shaft and said further shaft; magnetic field producing means mounted coaxially with said further shaft; magnetizable means mounted concentrically within said magnetic field producing means and defining an annular air gap therewith; an electrically conductive cup member mounted on said further shaft coaxially therewith and extending into said air gap for rotation with said further shaft, said cup member having eddy currents generated therein upon rotation of said further shaft which develop a restraining torque, said restraining torque being reflected through said gear transmission system to said input shaft; ferromagnetic shunt means mounted adjacent said magnetic field producing means for shunting a portion of the magnetic flux in said air gap, the permeability of said shunt means decreasing for increases in ambient temperature to compensate for the loss in eddy current torque resulting from increased electrical resistance of said cup member at said higher temperatures, and a ferromagnetic ring member surrounding said magnetic field producing means for shunting flux from the air gap, so as to control the restraining torque reflected to the input shaft, said annular ferromagnetic member being adjustable axially with respect to said magnetic field producing means.

2. The eddy current damper unit defined in claim 1, in which said magnetic field producing means comprises an annular permanent magnetic membEr which develops radially extending magnetic poles around the axis of rotation of said further shaft; and said magnetizable means comprises an annular magnetic member disposed coaxially within said annular permanent magnet member and surrounding said further shaft.

3. In combination: aircraft control system including at least one pivotally mounted control stick; a shaft; a linkage mechanism coupling the control stick to the shaft to produce rotation of the shaft upon pivotable movement of the control stick; an eddy current damper device having input shaft, said damper device providing a restraining torque to said input shaft which is directly proportional to the velocity at which the input shaft is rotated; and linkage means coupled to said input shaft and to said control stick, so that a restraining force is reflected to said control stick which is proportional to the velocity in which the control stick is actuated about its pivot point.
