Abstract (en)
The most frequent problems of water and air drainage devices designed for diesel motors are the following: a) in car motors, if water or air has to be drained from the filter, the car must be left in a garage; b) high power motor-water-separators need expensive maintenance and do not allow air discharge. The following notes show the new device peculiarity (device for immediate water and air expulsion from fuels). 1) The device is capable of detecting any kind of water by the use of one electrode (see CH. 1-2-3-9). 2) It can expell instantly even very small amounts of water. 3) Opening and closing filter plug (it has an external paching) by an electrovalve placed in the plug which has a threaded sleeve where the electrode is placed (see CH. 4-5-6). 4) Manual test available by an external pushbutton and warring light (see ch. 9) 5) A high degree of pump-depression allows water and air simultaneous discharge; in the same way, once the filter is replaced, water and fuel in excess are discharged in a few seconds by starting the device (see CH. 10 - 11). 6) The istruments-board-warning-lamp can also be used here (see CH. 8) 7) The pump can also be placed away from the filter and in high position 8) A particular filter precedes the pump (see CH. 7) <IMAGE>
