The invention provides a fuel filling device capable of keeping the outlet pressure of a VR pump constant. A fueling device (100) according to one embodiment of the present invention is characterized by comprising: a VR line (1) that communicates with a fueling nozzle (6) and a fuel tank (5) so as to return vapor generated during fueling to the fuel tank (5); a VR pump (2) that is provided in the VR line (1) and that sucks and discharges vapor; and a back pressure regulating valve (3) that is provided in a region of the VR line (1) on the discharge side of the VR pump (2) so as to maintain the pressure on the discharge port side of the VR pump (2) at a set value.
本发明提供一种能够使VR泵的出口压力恒定的燃料加注设备。根据本发明一实施例的燃料加注设备(100)的特征在于包括:VR管线(1),其与燃料加注喷嘴(6)和燃料贮罐(5)连通,以使燃料加注期间产生的蒸气返回到燃料贮罐(5);VR泵(2),其介设在VR管线(1)中,以吸入和排放蒸气;和背压调节阀(3),其介设在VR管线(1)的位于VR泵(2)的排放侧的区域中,以将VR泵(2)的排放口侧的压力保持在设定值。
