Receptacle, calibration device and filling apparatus
To provide a calibration device reliably accomplish communication filling without a great deal of labor when filling gaseous fuel (e.g., hydrogen gas) from a filling apparatus (e.g., a hydrogen filling apparatus) to a device to be filled (e.g., a hydrogen tank of an FCV) via the calibration device, and so on. A calibration device 100 according to the present invention includes a flowmeter 1 ; a filling nozzle 2 connected to the flowmeter 1 through a pipe 4 A, the filling nozzle 2 having a communication input part 2 A that receives information from a side 30 to be filled as an optical signal; and a receptacle 3 connected to the flowmeter 1 through a pipe 4 B, the receptacle 3 having a communication output part 3 A that outputs the signal received from the communication input part 2 A of the filling nozzle 2 to a filling nozzle side of a filling device 20 that fills gaseous fuel, wherein the communication output part 3 A is movable in a central axis direction of the pipe 4 B connected to the receptacle 3 , and an optical signal is emitted from the communication output part 3 A toward the central axis of the pipe 4 B.
1 . A calibration device comprising:
a flowmeter;
a filling nozzle connected to said flowmeter through a pipe, said filling nozzle having a communication input part that receives information from a side to be filled as an informational optical signal; and
a receptacle connected to said flowmeter through a pipe, said receptacle having a mounting member and a communication output part coupled to the mounting member, the communication output part being configured to emit an output optical signal corresponding to the informational optical signal received from said communication input part of said filling nozzle to said filling nozzle side of a filling device that fills gaseous fuel,
wherein said communication output part is translatable along the mounting member in a central axis direction of the pipe connected to the receptacle, and the output optical signal is emitted from said communication output part toward the central axis of the pipe.
2 . A filling apparatus comprising a filling device and a calibration device, and said calibration device including a flowmeter; a filling nozzle connected to said flowmeter through a pipe, said filling nozzle having a communication input part that receives information from a side to be filled as an optical signal; and a receptacle connected to said flowmeter through a pipe, said receptacle having a communication output part that outputs the signal received from said communication input part of said filling nozzle to a filling nozzle side of a filling device that fills gaseous fuel, said communication output part being translatable in a central axis direction of the pipe connected to the receptacle, and an optical signal being emitted from said communication output part toward the central axis of the pipe, wherein connecting said filling nozzle of the calibration device to the receptacle on the side to be filled, and connecting said filling nozzle on a filling device side to the calibration device provides functions of calibrating the filling device while filling it with gaseous fuel, and transmitting the optical signal from the side being filled to said communication input part of said filling nozzle on the filling device side to perform communication filling via a signal transmission means.
3 . The filling apparatus as claimed in claim 1 , wherein the communication output part is of an annular configuration.
4 . The filling apparatus as claimed in claim 1 , wherein the mounting member is of an axial configuration.
5 . The filling apparatus as claimed in claim 1 , wherein communication output part is configured to transmit the output optical signal at an angle relative to the central axis.
6 . The filling apparatus as claimed in claim 2 further comprising a notification means for notifying that communication filling has been established.
