Abstract
Degassing circuit for a liquid tank, including a degassing duct connecting the upper part of the tank to a higher point, close to the upper end of the filling duct, via a section in the form of a syphon and a liquid/gas separating volume provided at its base with a device for purging the liquid phase present in the degassing duct, in which the purging device brings the degassing duct into communication with the filling duct and is combined with a device creating a Venturi effect conducive, when filling, to purging the liquid phase present in the degassing duct.
Claims7
A degassing circuit for a liquid tank, comprising:
- a tank which contains a liquid up to a maximum filling level, the tank including an upper part above the maximum filling level in which gases are trapped;
- a filling duct connected to the tank, the filling duct including a Venturi section which creates a Venturi effect when liquid is introduced into the tank through the filling duct;
- a liquid/gas separating volume adjacent the filling duct, the separating volume including a base and a purging device at the base through which liquid entering the separating volume is purged to the Venturi section of the filling duct;
- and
- a degassing duct connecting the upper part of the tank to a point of the separating volume which is higher than the upper part of the tank, the degassing duct having a siphon-shaped part;
- whereby during filling of the tank with a liquid through the filling duct, any liquid present in the degassing duct and moved into the separating volume is drawn by the Venturi effect through the purging device and into the Venturi section.
