The new electromeccanic device (10+11+13+14), is capable of detecting water and impurity , when they to deposit of fuels sumptanks (2), and to permet the automatic discharge (15). The new device, for thanks still not used, he is formed of tow tubes, comunicatings a different levels with the sumptank (2). The upper tube ,he is connected with a little electrode container(11), where are placed four pair electrodes, to fixed a determinated levels (H1-H2-H3-H4). The electrodes are connected with four distinct electronic devices (14), capables to pilot the pneumatic valves (9), by electromagnetic valves (12). Device D1 to pilot the pneumatic valve (10) normally closed(N.C.)by timer T. " D2 " " " " " (8-9)normally open (N.O.)-upper level H2 " D3 " " " " " (8-9) " " (N.O.)-lower level H3 " D4 to " the alimentation timer T The lower tube Ts, is functioned like drainage by-pass. Consequently the level variations in the sumptank, are equal as the electrode container (11).To a better action device, to want water filled the sumptank, as to equal level H1 of the little container.When the water level reaches the level H4, to electric joint pair electrodes D4 and the alimentation timer T. When the water level reaches the level H1, to electric joint the pair electrodes E1, so excite the timer T and device D1; consequently, is open the pneumatic valve V1 (by electromagnetic valve Ev1). When the water level come down below the level H1, stopped electric joint E1 , but the Timer T delayte the closing the valve V1. When the water level come down below the level H4, stopped the timer alimentation, so closes the valve V1 In the new device for thanks in active function, the tube (6) is connected in by pass to siphon tube(3), while the tube (7), is connected to botton tank (1). The water volume included to the level H1-H4 is proportional a upward part to siphon (3) , so ,all impurity of bottom sumptank (2) to come discharged. <IMAGE>
