- the filling nozzle 7 is connected to the tip side of the filling hose 6 (first hose 6A) in an airtight state, and constitutes a so-called filling coupling.
- the filling nozzle 7 is connected to the dispenser housing 4 (more specifically, the hydrogen gas supply pipe line 5) and the filling hose 6 (hose 6A, 6B).
- the filling nozzle 7 has a built-in on-off valve (not shown). The on-off valve is switched between an "open position” that allows the flow of hydrogen gas and a "closed position” that shuts off the flow of hydrogen gas.
- the filling nozzle 7 may be provided with a check valve instead of the on-off valve or together with the on-off valve.
- the check valve allows the flow of hydrogen gas from the filling nozzle 7 to the filled tank 10 and blocks the flow of hydrogen gas from the filled tank 10 to the filling nozzle 7.
- the dispenser unit 3 is connected to an inlet valve 14 which is located in the middle of the hydrogen gas supply pipeline 5 and is opened and closed by, for example, a manual operation, and a downstream side of the inlet valve 14.
- a flow rate adjusting valve 15 as a control valve that controls the flow rate of fuel flowing through the hydrogen gas supply line 5 by being opened and closed by the control device 27 is connected to the downstream side of the flow rate adjusting valve 15.
- a shutoff valve 16 which is a valve device is provided.
- the flow meter 20, the flow rate adjusting valve 15, and the shutoff valve 16 provided from the upstream side to the downstream side of the hydrogen gas supply pipeline 5 are arranged (in the order of installation) in the order shown in FIG. It is not limited.
- the flow rate adjusting valve 15 provided in the dispenser unit 3 is, for example, a pneumatically operated valve device, which is opened by supplying air and controls the control pressure (air pressure) by a control signal (control current). The valve opening is adjusted.
- the flow rate adjusting valve 15 is controlled to an arbitrary valve opening degree by a command based on the control program of the control device 27, and variably controls the flow rate and hydrogen gas pressure of hydrogen gas flowing in the hydrogen gas supply pipeline 5. That is, the flow rate adjusting valve 15 is opened by supplying compressed air (instrumentation air, driving gas) such as compressed air and compressed nitrogen gas through an air supply pipeline 11 as a driving gas supply path.
- the flow rate adjusting valve 15 is connected to an air supply pipeline 11 for supplying compressed air.
- the compressed air supplied to the flow rate adjusting valve 15 is adjusted by the solenoid valve 12 provided in the middle of the air supply line 11.
- the solenoid valve 12 is, for example, a normally closed solenoid valve that is always in a closed position and is connected to the control device 27.
- the valve opening degree of the solenoid valve 12 is controlled based on the control current supplied from the control device 27.
- the flow rate adjusting valve 15 is adjusted to a required opening degree by supplying compressed air through the solenoid valve 12 whose valve opening degree is controlled by a control current from the control device 27.
- the shutoff valve 16 is a pneumatically operated valve device provided in the middle of the hydrogen gas supply pipeline 5 (for example, between the flow rate adjusting valve 15 and the cooler 17).
- the shutoff valve 16 is opened and closed based on a control signal from the control device 27 to allow or shut off the flow of hydrogen gas (fuel gas, filled gas) in the hydrogen gas supply pipeline 5. That is, when the control device 27 fills the filled tank 10 of the vehicle 9 with hydrogen gas via the filling nozzle 7, or when the filling of hydrogen gas is stopped (finished), the flow rate adjusting valve 15 and the shutoff valve The valve opening and closing control with 16 is performed.
- the shutoff valve 16 is also opened by supplying compressed air (instrumentation air, drive gas) through an air supply line 11 as a drive gas supply path.
- an air supply line 11 for supplying compressed air is connected to the shutoff valve 16.
- the shutoff valve 16 is a normally closed valve that maintains a closed state unless compressed air having a predetermined pressure or higher is supplied.
- the compressed air supplied to the shutoff valve 16 is controlled by the solenoid valve 13 provided in the middle of the air supply line 11.
- the solenoid valve 13 is, for example, a normally closed solenoid valve that is always in a closed position and is connected to the control device 27.
- the solenoid valve 13 opens when a control current is supplied from the control device 27.
- the shutoff valve 16 is opened by supplying compressed air through the solenoid valve 13 whose opening and closing is controlled by the control current of the control device 27. At this time, the shutoff valve 16 is maintained open by the compressed air when the supplied compressed air has a predetermined pressure (or is higher than the predetermined pressure).
- the cooler 17 is a cooling device for cooling the hydrogen gas flowing in the hydrogen gas supply pipeline 5.
- the cooler 17 cools the hydrogen gas at a position in the middle of the hydrogen gas supply pipeline 5 in order to suppress the temperature rise of the hydrogen gas filled in the tank 10 to be filled. That is, the cooler 17 cools the hydrogen gas supplied to the vehicle 9 (filled tank 10) via the hydrogen gas supply line 5.
- the cooler 17 has a heat exchanger 18 provided in the middle of the hydrogen gas supply line 5 (for example, between the shutoff valve 16 and the temperature sensor 22), and the refrigerant lines 17A and 17B in the heat exchanger 18. It is configured to include, for example, a chiller unit 19 provided with a drive mechanism (not shown) such as a compressor or a pump.
- the cooler 17 includes a refrigerant conduit 17A on the supply side for supplying a refrigerant (for example, a liquid containing ethylene glycol or the like) from the chiller unit 19 toward the heat exchanger 18, and the chiller unit 19 from the heat exchanger 18.
- a return-side refrigerant conduit 17B for returning the heat-exchanged refrigerant toward the side is provided.
- the chiller unit 19 circulates the refrigerant between the chiller unit 19 and the heat exchanger 18 via the refrigerant pipes 17A and 17B.
- the heat exchanger 18 of the cooler 17 exchanges heat between the hydrogen gas flowing in the hydrogen gas supply pipeline 5 and the refrigerant, and defines the temperature of the hydrogen gas supplied toward the filling hose 6. Reduce to temperature (eg, ⁇ 33 to ⁇ 40 ° C.).
