Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHA
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F  Y | IPC F

Claim 3:
4. A hydrogen supplying device comprising:
a liquid hydrogen pump configured to pressurize liquid hydrogen stored in a liquid hydrogen tank;
an evaporator configured to convert the liquid hydrogen discharged from the liquid hydrogen pump into hydrogen gas;
a pressure chamber configured to be filled with the hydrogen gas flowing therein from the evaporator and to supply the filled hydrogen gas to a hydrogen engine;
a pump control unit configured to adjust a discharge flow rate of the liquid hydrogen pump, and configured to adjust, based on both a flow rate of hydrogen to be supplied to the hydrogen engine and an actual pressure in the pressure chamber, the discharge flow rate of the liquid hydrogen pump so as to match the actual pressure in the pressure chamber with a target pressure;
a pressure sensor configured to detect the actual pressure in the pressure chamber; and
a flow rate sensor configured to detect an actual flow rate of hydrogen gas to be supplied to the hydrogen engine, wherein
the pump control unit is further configured to adjust the discharge flow rate of the liquid hydrogen pump, based on both the actual flow rate of hydrogen gas detected by the flow rate sensor and the actual pressure in the pressure chamber detected by the pressure sensor.
