Valve assembly

A valve assembly comprising:

• a body;
• and
• a composite valve sub assembly attached to the body, wherein:
• the body includes
• a gas flow path including a first flow path configured to be connected to a gas tank and a second flow path configured to be connected to an external device, and
• a single attachment hole that communicates with each of the first flow path and the second flow path;
• the composite valve sub assembly includes
• a tubular sleeve inserted into the attachment hole,
• an electromagnetic valve body housed in the sleeve,
• a solenoid actuator configured to move the electromagnetic valve body in the sleeve,
• a plug fixed at an end portion of the sleeve and disposed between the sleeve and a bottom surface of the attachment hole, and
• a check valve body disposed on an opposite side of the electromagnetic valve body from the plug;
• the plug has an internal flow path including a first opening connected to the first flow path and opened and closed by the electromagnetic valve body, and a second opening connected to the second flow path and opened and closed by the check valve body, and the plug is configured to be moved in a direction of getting out of the attachment hole together with the sleeve by moving the sleeve in the direction of getting out;
• and
• the valve assembly is configured such that a gas flows from the first flow path to the second flow path, without passing inside the composite valve sub assembly, when the plug is moved in the direction of getting out together with the sleeve.
