摘要：
Provided are a hydrogen compressor and a hydrogen filling system capable of increasing purity of a hydrogen gas via surely discharging oil trapped from a discharged gas and accumulated in a vessel even during operation of the compressor, and also preventing leakage of the hydrogen gas from an oil discharge pipe. The hydrogen compressor includes vessels of a snubber and a filter each arranged at a downstream side of the final compressing stage of the compressor. The hydrogen compressor further includes oil discharge pipes each connected with a bottom of each vessel, and level sensors each detecting a level of oil accumulated in each vessel. The oil discharge pipes include automatic valves configured to open/close based on detection values of the level sensors. The oil discharge pipes join to be an oil discharge pipe including a manual valve controlling an oil flow rate in the oil discharge pipe.
摘要（中）：
本发明提供一种氢压缩机和氢填充系统，即使在压缩机的运转中，也能够可靠地排出从排出气体中捕集并积存在容器内的油，并且能够防止氢气从油泄漏 排放管。 氢压缩机包括缓冲器和过滤器的容器，每个过滤器布置在压缩机的最终压缩级的下游侧。 氢压缩机还包括排油管，每个排油管与每个容器的底部连接，以及液位传感器，每个液位传感器检测每个容器中累积的油的液位。 排油管包括基于液位传感器的检测值而打开/关闭的自动阀。 排油管接合成排油管，该排油管包括控制排油管中的油流量的手动阀。
