Abstract
The device uses an elastic tubular bladder for receiving liquid which is expandable radially generally spherically at a local segment until a fully-expanded cross-section is achieved at which time the expanded region begins to grows axially, thereby maintaining a relatively constant pressure independent of bladder volume. The device is provided with a nozzle and a valve for controlling and directing the flow of the projected liquid.
