Claims

[Scope of utility model registration request]

A cylindrical body for attaching a valve chamber forming cylindrical body is connected to the front end side of the base pipe with a gas passage, which has a connection part for a gas feed pipe from a high-pressure gas supply source on the rear end side. A valve seat is formed on the inner wall side of the front end wall of the valve chamber forming cylindrical body having a front end wall, and the valve seat is formed on the cylindrical body for attaching the valve chamber forming cylindrical body of the base pipe part, and the valve seat is formed on the inner wall surface side of the front end wall of the valve chamber forming cylindrical body body having a front end wall. A valve chamber is formed by attaching a valve chamber forming cylinder part in which a valve body pushing cylinder part guiding cylinder having a gas passage opened in the valve seat extends in the center part. In the valve chamber, a spring is always biased toward the valve seat so that the valve surface is in airtight contact with the valve seat, and the valve surface is in contact with the valve seat. At this time, a valve body mainly consisting of a valve body is provided with a rod for transmitting a force for transmitting the valve body through the gas passage of the cylinder body for guiding the valve body for pushing the valve body; The guide cylinder has a
A contact portion that is brought into airtight contact with a filling port formed in a gas supply valve in a high-pressure gas container, and a contact portion that is brought into contact with the gas passage and the front end of the rod for transmitting force for pushing the valve body. a valve-equipped high-pressure gas filling cannula in which a valve-element-feeding cylindrical body part having a contact surface part is slidably fitted in an airtight manner; As the degree of attachment to the filling port progresses, after the abutting part of the valve body pushing cylinder part is brought into airtight contact with the filling port, the valve body pushing cylinder part is caused to slide relative to the valve body pushing cylinder part guiding cylinder, and the valve body in the valve chamber resists the biasing force of the spring through the valve body pushing force transmitting rod. and a connecting member that is moved to separate the valve surface of the valve body from the valve seat of the valve chamber, thereby allowing gas from the high-pressure gas supply source to be filled into the high-pressure gas container through the filling port. A high-pressure gas filling fitting with a valve featuring:
