Abstract
An accumulator comprising: (a) a vessel body having an inner space; (b) a deformable partition member fixedly disposed in the inner space so as to fluid-tightly divide the inner space into a gas chamber charged with a suitable pressurized gas, and a fluid chamber connectable through a communicating passage with a piping system for permitting flows of a working fluid through the communicating passage between the piping system and the fluid chamber in response to variations of the pressure of the working fluid, so as to minimize the variations; and (c) an opening and closing device disposed in the communicating passage, the opening and closing device opening the communicating passage thereby to permit the flows of the working fluid except when a rate of increase of the pressure of the working fluid is higher than a predetermined upper limit, the opening and closing device closing the communicating passage thereby to inhibit the flows of the working fluid when the rate is higher than the predetermined upper limit.
