摘要

#CMT# #/CMT# The damper (1) has plates (3, 4, 6), where the plate (6) is rotatable opposite to the other plates (3, 4), and a liquid e.g. fused salt liquid, provided in a gap (7) between the plates, where the gap between the plates extends radially outward. The liquid exhibits a large surface tension, so that the liquid moves into the gap between the plates. The plate (6) exhibits a flat cone on its side facing the other plates (3, 4), where the liquid exhibits desired capillary effect. #CMT#USE : #/CMT# Liquid e.g. ionic liquid such as fused salt liquid and silicone oil, rotation damper for absorbing the spring-actuated movement of a flap and a drawer of an HiFi-device and a grap handle in an automobile. #CMT#ADVANTAGE : #/CMT# The rotation damper holds the liquid between the plates in a simple manner. The utilization of the ionic liquid eliminates the need of gas density sealing, so that the danger of the liquid being volatilized by evaporation is avoided. The liquid has reduced viscosity with increasing shear rate, and has reduced absorption characteristics. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an axial sectional view of a liquid rotation damper. 1 : Liquid rotation damper 2 : Cylinder-tubular housing 3, 4, 6 : Plates 7 : Gap 8 : Gear wheel.
