Separator nipple

A tank installation for a motor vehicle, the tank installation comprising:

• a tank;
• a vent inlet line for connection to the tank;
• a filler pipe configured to refuel the tank;
• a vent outlet line for connection to a fuel vapour filter;
• and
• a separation nipple that includes:
• a separation nipple inlet for connection to the vent inlet line;
• a separation nipple outlet for connection to a vent outlet line;
• a separation nipple opening for connection to an interior of the filler pipe;
• and
• a flap having a main flap surface to close the separation nipple opening when the flap is in a closed position, and a reflector flap surface which extends from and slopes at a predetermined angle relative to the main flap surface, to block a flow path of the liquid in a direction towards the vent outlet line when the flap is in an open position, the reflector flap surface and the main flap surface configured to form a reflector when the flap is in the open position, to thereby deflect liquid passing through the separation nipple opening in a direction towards an end of the tank of the filler pipe.

A motor vehicle, comprising:

• a filler pipe;
• a vent inlet line;
• a vent outlet line:
• a separation nipple to separate liquid fuel from the vent inlet line into the filler pipe, the separation nipple including a separation nipple inlet for connection to the vent inlet line, a separation nipple outlet for connection to the vent outlet line, a separation nipple opening for connection to the filler pipe to discharge the separated liquid fuel into the filler pipe, and separation nipple partition walls to separate the liquid fuel from fuel vapour;
• and
• a flap pivotably moveable between a first position and a second position, the flap having a main flap surface to close the separation nipple opening when the flap is in the first position, and a reflector flap surface to rest against one of the separation nipple partition walls and thereby prevent flow of the liquid into the vent outlet line when the flap is in the second position, the reflector flap surface and the main flap surface configured to deflect, when the flap is in the second position, the liquid fuel that passes through the separation nipple opening towards a direction of a tank end of the filler pipe.
