| 摘要 | PURPOSE:To easily supply constant-pressure air from an airpipe without power by disposing a weight on a gas-tight flexible film forming an enclosed receptacle and fixing same, and further by connecting an air supply pipe to the enclosed receptacle. CONSTITUTION:Air is poured into an air storing tank 20 enclosed by gas-tight rubber rubberized fabrics 1, 2 through an air-supply pipe 7, and when the air pressure in the storing tank is over a set value, a steel case 3 for a weight is lifted up by the air pressure. If the air continues to be supplied, the steel case 3 for a weight continues to rise and stops rising at a position of a stopper 11 for the steel case. Air supply from the air storing tank is started by opening a manually operated valve 9 in an airpipe 15. The quantity of supplying air can be easily controlled by the opening of the manually operated valve 9, the diameter of the airpipe 15 or mounting a reducer in the airpipe. | ||||||
