A fuel gas supplying and filling system for a fuel gas consuming unit, capable of using a supply passage in both filling and supplying operations and improving the airtightness and reliability of a fill passage. A high-pressure tank and a fuel gas consuming unit are connected to each other by a supply passage, and an electromagnetic pressure regulating valve is provided on the supply passage. An electromagnetic on-off valve is provided between the electromagnetic pressure regulating valve and the high-pressure tank. A fill passage is connected to a portion of the supply passage, the portion being located between the electromagnetic pressure regulating valve and the electromagnetic on-off valve. The fill passage is configured such that the high-pressure fuel gas can be supplied through a filling opening. When the high-pressure fuel gas is introduced to a downstream side of the electromagnetic on-off valve, the electromagnetic on-off valve opens the supply passage.

The present invention provides a pressure reducing valve having excellent responsiveness, durability, and reliability and stable output characteristics. A pressure reducing valve includes a housing, and the housing includes a valve passage connected to a primary port and a secondary port. A valve element is provided in the housing. The valve element can adjust an opening degree of the valve passage by moving between a closed position where the valve element closes the valve passage and an open position where the valve element opens the valve passage. The valve element is pressed toward the closed position by secondary pressure. A spring member is provided to bias the valve element toward the open position against the secondary pressure. Further, a rolling bearing is provided on the valve element, and the valve element is movably supported by the rolling bearing.

A gas pressure regulating valve capable of regulating secondary pressure of a high-pressure fuel gas to a target pressure and preventing the fuel gas from leaking. An electromagnetic pressure regulating valve is an in tank type and can cause a valve body to move to adjust an opening degree of a valve passage. A diaphragm seal and a low-pressure sealing member respectively seal both sides of a bearing member slidingly supporting the valve body. The diaphragm seal receives the secondary pressure from a pressure return chamber. A back pressure chamber connected to a primary port is formed in the valve body by a seal rod inserted in the valve body. A communication passage connected to a secondary port is formed at a side of the seal rod, and a high-pressure sealing member seals between the communication passage and the back pressure chamber.

A hydrogen gas supply device supplies hydrogen gas to a fuel cell stack and includes an electromagnetic pressure regulating valve that regulates the pressure of the hydrogen gas to low pressure. The electromagnetic pressure regulating valve includes a housing, and a valve passage connecting a primary port and a secondary port is formed in the housing. A valve body controls an opening degree of the valve passage and is provided in the housing. A high-pressure sealing member and low-pressure sealing member are provided on an outer periphery of the valve body. The high-pressure sealing member and the low-pressure sealing member are provided in this order from one end side of the valve body to the other end side thereof. The electromagnetic pressure regulating valve further includes a housing pressure equalizing passage connecting the secondary port and a buffer chamber formed between the high-pressure sealing member and the low-pressure sealing member.

A medical device includes a main body elongated in a vertical direction. A guide section protrudes from a lower end of the main body in a direction crossing the vertical direction and includes first and second guide holes. A first unit includes a first puncture needle slidably supported by the main body near an upper end of the first puncture needle in the vertical direction and having a sharp lower end slidably inserted into the first guide hole from above. The first unit has a first holding plate integrally fixed to the first puncture needle. A second unit includes a second puncture needle slidably inserted into the second guide hole from above and a second holding plate integrally fixed to the second puncture needle. The second holding plate separably abuts on the first holding plate from above. A position of the second guide hole is selectable along the guide section.
