<p>To be able to use water under pressure as a driving energy for various liquids in a handsprayer, an elastic bladder (2), such as a rubber bladder, connectable to a water pipe under pressure, has been disposed in a pressure vessel (1). On supplying pressurized water to the bladder, the latter will expand and in doing so will compress surrounding air (3) contained in the pressure vessel, which air will then pressurize the liquid (4) present in the vessel for spraying. When an adequate amount of pressurized water has been supplied to the bladder, the handsprayer is charged. By opening and closing an adjustable nozzle (7) connected to the handsprayer, the latter may then be used for emptying and spraying the liquid contained in the vessel.</p> |
