GAS-FILLING APPARATUS AND METHOD FOR FILLING GAS

摘要

A gas-filling apparatus includes a gas flow passage including an inflow end to which a gas supply source is connectable and an outflow end to which a pressure accumulator is connectable, a compressor, a storage portion, and an operation control portion conducting a first compression filling operation in which a gas supplied from the gas supply source connected to the inflow end is compressed by the compressor to be discharged from the outflow end and a second compression filling operation in which the gas stored in the storage portion is compressed by the compressor to be discharged from the outflow end, the operation control portion conducting the first compression filling operation until a pressure of the gas at the outflow end reaches a predetermined pressure and executing a control for shifting the first compression filling operation to the second compression filling operation when the pressure has reached the predetermined pressure.

1. A gas-filling apparatus comprising:
a gas flow passage including an inflow end to which a gas supply source is connectable and an outflow end to which a pressure accumulator is connectable; a compressor connected to the gas flow passage; a storage portion connected to the gas flow passage; and an operation control portion for executing a control for a first compression filling operation in which a gas supplied from the gas supply source connected to the inflow end is compressed by the compressor to be discharged from the outflow end and a second compression filling operation in which the gas stored in the storage portion is compressed by the compressor to be discharged from the outflow end, wherein the operation control portion is configured to conduct the first compression filling operation until a pressure of the gas at the outflow end or a pressure corresponding to the pressure of the gas at the outflow end reaches a predetermined pressure and to conduct a control for shifting the first compression filling operation to the second compression filling operation when the pressure of the gas at the outflow end or the pressure corresponding to the pressure of the gas at the outflow end has reached the predetermined pressure.
