专利汇可以提供Working liquid for buffer专利检索,专利查询,专利分析的服务。并且PURPOSE:To provide stable attenuating force characteristics having small viscosity variation due to change in temperature by using moisture system working liquid containing water of main component and anticorrosive and lubricant added thereto. CONSTITUTION:When the external force is applied to a piston rod 1 of a buffer, a piston 3 moves in a cylinder 2 so that working filler liquid flows through an orifice 4 formed in the piston 3 to damp the motion of the piston by its flow resistance and provided a damping function. This working filler liquid contains, for example, 75wt% of water, 15wt% of antifreezing agent like glycol, 5wt% of viscosity increasing agent like water soluble polymer and 5wt% of additives such as anticorrosives like benzole, lubricant like ester phosphate, oiliness agent for reducing coefficient of friction, foam erasing agent, etc. Thus is provided working liquid which has large specific heat, small change in viscosity caused by change in temperature and stable attenuating force irrespective of the change in temperature.,下面是Working liquid for buffer专利的具体信息内容。
