Definitions

  • the invention relates to a conduit system for supplying an oil burner with fuel oil from an oil tank.
  • the oil supply of a burner is structured as follows: oil is drawn in from an oil tank with the help of a float and an oil pump. By the float fuel oil is sucked from the surface of the fuel oil located in the heating oil tank. Water and other impurities remain at the bottom of the oil tank to prevent oil burner malfunction.

  • This refinement of the line system according to the invention significantly increases its safety. In the case of leakage of the outer pipe is drawn in due to the prevailing there and generated by the suction negative pressure air. The possible amount of fuel oil leaving is therefore very small. In the inner pipe there is a higher pressure. In the event of a leakage in the inner pipe, the fuel oil flowing here will pass into the outer pipe and continue to be conveyed by the suction device. If the entire double line is severed, only the fuel oil already in the double line can escape.

Abstract

L'invention concerne un système de conduite servant à alimenter un brûleur fioul (4) en fioul domestique (6) provenant d'une cuve à fioul (2). Le système de conduite selon l'invention comprend une conduite double (9, 21) dans laquelle une conduite interne (11, 23) est placée dans une conduite externe (10, 22). Ce faisant, la section formée (12, 24) entre la conduite interne (11, 23) et la conduite externe (10, 22) est reliée à un dispositif d'aspiration (7). On augmente ainsi de manière importante la sécurité du système de conduite pour l'alimentation du brûleur fioul (4) en fioul domestique (6).
