Filler head avoiding a premature nozzle shut off

A filler head for a storage system comprising:

• a body to be mounted inclined according to a predetermined angle regarding a gravity direction, called a filling direction, and including a main part closed by a cover part so as to form a cavity in which a separating device is received, the filler head being configured to receive, in a cylindrical wall of the separating device extending around the filling direction, a distribution nozzle of a fluid with an automatic stop sensor to prevent overfilling of the filler head, the filler head being configured to be connected to a filling line and a venting line of a fluid tank and the separating device being arranged to improve partitioning of flow coming from the venting line and flow going to a filling line, and
• a buffer volume mounted between the cavity and the venting line in one-piece with the main part in a back portion of the body so as to reduce a speed of flow coming from the venting line before entering the cavity,
• wherein the cylindrical wall comprises at least one recess facing an opening of the buffer volume in the back portion of the body, the cylindrical wall guiding along a front portion of the body, located in an opposite direction to the back portion regarding the filling direction, any fluid outgoing from the nozzle so as to ensure:
• a laminar flow of the fluid outgoing from the nozzle towards the filling line in the front portion of the body, and
• a direct venting of fluid through the recess of the cylindrical wall in the back portion of the body coming from the venting line in order to be expelled outside the filler head into ambient air,
• thus permitting to limit any fluid dispensing shut off during refilling stage.
