The gas purge assembly includes a joint assembly (11), a valve (13) connected between the joint assembly (11) and the purging gas supply line (27), and a 3 ports valve (12) for selectively connecting the joint assembly (11), the main line (24) and the purging gas exhaust line (29). The joint assembly (11) has a purging gas supply path for supplying a purging gas from the purging gas supply line (27) to a cylinder connection portion (14) and a purging gas exhaust path for supplying the purging gas in the cylinder connection portion (14) to the 3 ports valve (12).</p> |
