<p>An air reservoir (1) is installed in a water vessel (3) with its bottom inlet opening (2) remaining below the surface (4) of the water. Air produced by a miniature pump (6) enters the inlet opening through an air hose (5), and compressed air is taken from the reservoir via a valve (7) and a downstream distributor (8). The air reservoir may be designed with a flexible shell, or may be a funnel-shaped or bell-shaped vessel with rigid walls.</p> |
