Abstract
An accumulator (10) has a freely movable, flexible and deformable bladder (20) with a single relatively rigid ring (40) stationarily secured thereto and defining a circle on the bladder which remains substantially uniplanar with itself during the flexing and deforming movement of the bladder but moves with the bladder along variable deformation planes of random orientation. The bladder freely and randomly flexes and deforms such that the circle is randomly oriented along random and varying planes during movement of the bladder during a cycle.
