Abstract: A fast charging medical oxygen dispenser including a specially designed valve which has a fixed valve seat and a freely movable valve body. In dispensing position the valve body nests closely within the valve seat with the valve body having an extremely small dispensing opening which allows the gas to pass from a storage space and then through the valve for dispensing purposes. In fast charging condition the valve body is urged somewhat away from the valve seat with the valve body having an enlarged slot which is closed off during the dispensing action, but which is opened when the valve body is urged away from the valve seat so that gas can quickly pass through the enlarged slot and into the storage area.
