<p>PURPOSE:To regulate accurately a gas filling up pressure by providing a gas filling up pressure automatic measuring device, an automatic gas supply device and a controller. CONSTITUTION:An automatic measuring device 30 measuring the gas filling up pressure of a gas chamber 7, an automatic gas supply device 31 feeding/ discharging gas to an accumulator 3 and a controller 32 connected to a space between the automatic measuring device 30 and the automatic gas supply device 31 are provided at the accumulator 3. As a result, the measured pressure of the automatic measuring device 30 is automatically converted into the gas filling up pressure at a designed temperature by the controller 32. And this gas filling up pressure and the designed gas filling up pressure are compared, and when a difference has occurred between both pressures, the automatic gas supply device 31 is automatically operated by the controller 32. Accordingly, the gas filling up pressure can be accurately regulated.</p> |
