摘要： PROBLEM TO BE SOLVED: To enable gas filling by using the existing filling device as it is and to execute gas filing at a low cost in a simple structure. SOLUTION: A lock means 55 formed by a magnetic body is mounted between a valve opening means storing part 53 and a check valve element opening means 51. The lock means 55 is switched between a locking attitude for limiting the forward and backward movement of the check valve element opening means 51 positioned in a valve opening releasing position X and a lock release attitude M for allowing the forward and backward movement. The check valve element valve opening means 51 is pressed by a valve opening operating means 60 having a lock release means 61. When the check valve element opening means 51 is pressed by the valve opening operating means 60, the lock means 55 is switched from the locking attitude to the lock releasing attitude by magnetic force produced between the lock means 55 and the lock releasing means 61.

摘要： PROBLEM TO BE SOLVED: To provide a cylinder valve with a check valve capable of effectively filling fluid from an outlet hole in a short time, and decreasing the outer diameter size of an outlet nozzle. SOLUTION: In the housing 4 of the cylinder valve 3, a check valve installing hole 31 is formed, and a cylindrical body 32 is installed. A check valve chamber 28 is formed in the cylindrical body 32, and a check valve seat 42 is formed at a check valve chamber inlet 40. A check valve body receiving portion 46 is fixed at a position facing to a check valve body 29 through the check valve chamber inlet 40. A retreat operating portion 50 is formed on an outer surface of the cylindrical body 32, and by pressing the retreat operating portion 50, the cylindrical body 32 is shifted from a take-out attitude A to a retreated filling attitude B. In the middle of shifting, the check valve body 29 is received by the check valve body receiving portion 46, and the cylindrical body 32 is further retreated from a check valve body limiting position to shift to the filling attitude B, thereby separating the check valve body 29 and the check valve seat 42.
