Abstract
It is well known that gas bubbles in liquid can absorb pressure fluctuations as well as flow rate ones. This has led to the idea that a large number of small bubbles enclosed in rubber can reduce the surges and pulsations produced by hydraulic oil flows. With the intention to develop a new method of reducing flow fluctuations, rubber containing many discrete micro-bubbles has been experimentally examined in terms of its ability to absorb fluctuations in actual hydraulic oil flows. The rubber seems to be available for this purpose, indicating that it could be a possible convenient tool in reducing pulsations in oil flows.
