PROBLEM TO BE SOLVED: To pressurize a gas vessel by utilizing pressure of working fluid discharged from a hydraulic pump and keep gas pressure in the vessel to be constant, in a system supplying fuel gas from the gas vessel to a motor. SOLUTION: The gas vessel 1 and a pressurizing cylinder 14 are arranged on the same axis and their pistons 9, 16 are connected by a rod 17, and discharge oil of the hydraulic pump 4 which is driven by an engine 3 is introduced into the pressurizing cylinder 14, so that the pressure of the working fluid presses the pressurizing cylinder 14 and pistons 16, 9 of the piston to pressurize the inside of the gas vessel 1. Further, a travel distance of the rod 17 equivalent to a travel distance of the piston is detected as a remaining amount of fuel by a stroke sensor. COPYRIGHT: (C)2006,JPO&NCIPI
