<p>A pulsator device connectable to a pressurized fluid supply line, particularly a water supply line, for converting the fluid pressure of the line to a pulsating pressure. The pulsator device comprises a valve (2) which is normally closed, automatically opens at a predetermined opening pressure to connect its inlet (107) to its outlet (106), and automatically closes at a predetermined closing pressure lower than its opening pressure. The pulsator device further includes a reservoir (102) for the fluid such that when the valve (2) is closed the reservoir (102) fills up and at the same time builds up pressure until the valve (2) opens to discharge the fluid within the reservoir (102).</p> |
