Abstract
A fuel purifier for separating and removing polluting water from hydrocarbon fuels, comprising a decantation vessel having at its upper end a normally open inlet and an outlet opening and at its bottom end a second normally closed outlet opening, a source of light and a photocell arranged in opposite positions in a tubular central wall portion of the decantation vessel, and a float vertically movably mounted within the decantation vessel to normally close the path of light from the source of light to the photocell, but adapted to move under the action of the water accumulating at the bottom of the decantation vessel to an upper position in which the photocell receives light from the source of light to open the second outlet opening to drain the water.
Claims3
A device for separating liquids of different densities, particularly for purifying liquid hydrocarbon fuels from water, comprising a decantation vessel having in inlet opening and an outlet opening for the liquid to be purified, both normally open and arranged at an upper end of said decantation vessel, and a second outlet opening normally closed and arranged at a lower end of said decantation vessel;
- a source of light for casting a beam of light through a lower wall portion of said decantation vessel;
- a photocell arranged on a lower wall portion of said decantation vessel in a position opposite said source of light for receiving said beam of light;
- an opaque float of a weight heavier than the liquid to be purified, but lighter than water, said opaque float being movably mounted within said decantation vessel for movement between a lower position for intercepting said beam of light and an upper position for receiving said beam of light;
- said photocell being arranged to control closure of said first outlet opening and opening of said second outlet opening when said opaque float is in said upper position.
