Experimental and Theoretical Analysis of Active Charge Accumulator for Water Hydraulics System.

The active charge accumulator (ACA) is a pressure converter device in a water-hydraulic system that is able to increase and decrease pressure without using a pressure-regulating valve. The basic characteristics of ACAs, however, have not yet been sufficiently revealed. In this paper, we experimentally examined the basic characteristics of ACAs with focus placed on how ACAs reduce pressure. This ex...
