ELECTRICALLY VISCOUS LIQUID AND ELECTRICALLY VISCOUS FLUIDSEALED DEVICE

摘要

PURPOSE:To solve the deterioration in the physical properties of an organic member by sealing an electrically viscous liquid in a device and preventing the extraction of components essential for the practical use of the organic member from the organic member of the device contacting with the electrically viscous liquid. CONSTITUTION:An electrically viscous fluid to be charged into a shock absorber 1 is preliminarily compounded with components such as a plasticizer to be extracted with the electrically viscous fluid from an organic member such as flexible member 2 contacting with the electrically viscous fluid. Since the concentrations in the electrically viscous fluid of the components to be extracted with the electrically viscous fluid is balanced with the concentration of the components in the organic member such as a rubber or resin member in the phase equilibrium, the extraction of the components from the organic member is practically prevented and the deterioration in the physical properties of the organic member is eliminated.
