Valve assembly

A valve assembly comprising:

• a body having a gas flow passage including a first flow passage and a second flow passage, a first attachment hole connected to the first flow passage and the second flow passage, and a second attachment hole connected to the first flow passage and the second flow passage;
• and
• a plurality of valve subassemblies, wherein
• the first flow passage is configured to be connected to a gas tank that stores a gas,
• the second flow passage is configured to be selectively connected to any one of a plurality of external devices,
• the plurality of external devices includes a supply source of the gas to be charged into the gas tank, and a consumption device configured to consume the gas fed out of the gas tank,
• the plurality of the valve subassemblies include:
• a check valve attached to the first attachment hole;
• and
• an electromagnetic valve attached to the second attachment hole,
• the first flow passage includes:
• a charging portion connecting the first attachment hole to the gas tank;
• and
• a feeding portion connecting the second attachment hole to the gas tank,
• the second flow passage includes:
• a common port that is an inlet for the gas supplied from the supply source and an outlet for the gas to be fed to the consumption device;
• a linear first portion extending from the common port;
• a linear second portion extending from the linear first portion;
• a linear third portion connecting the first attachment hole to the linear second portion;
• and
• a linear fourth portion connecting the second attachment hole to the linear second portion,
• the check valve is configured to restrict a flow of the gas from the charging portion to the linear third portion and allow a flow of the gas from the linear third portion to the charging portion,
• the electromagnetic valve is configured to control a flow of the gas from the feeding portion to the linear fourth portion,
• the linear third portion intersects the linear second portion at an angle equal to or smaller than 90° with respect to a first connection point of the linear second portion to the linear first portion, and
• the linear fourth portion extends parallel to the linear second portion from an end opposite to the first connection point with respect to a second connection point of the linear second portion to the linear third portion.
