Abstract

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)
