<P>PROBLEM TO BE SOLVED: To provide a steam pipe structure of a coffee maker surely controlling the quality of steam. <P>SOLUTION: A flow saving valve mount 1 is installed with a connecting pipe and fixed with a valve mount in its lower part. The valve mount is connected with a circulation pipe 5, and the connecting pipe and the circulation pipe 5 communicate with each other in a hollow in the valve mount. A closing valve 3 is installed on the valve mount and a thin film 32 of an elastic body is installed at the circumferential edge of a central valve element. The thin film 32 is installed with a fold 33 and the fold 33 is installed with a vent hole 331. The circumferential edge of the fold 33 abuts on just the inside of the valve mount and the outside diameter of the valve element 31 is sealed in the inside diameter of the circulation pipe 5. The valve element is thus regularly separated from the inside diameter of the circulation pipe 5 by the thin film 32, the closing valve 3 is communicated with the vent hole 331 and the circulation pipe 5, the closing valve receives a steam pressure, and when the valve element 31 pressurized the thin film 32 downward, the valve element 31 seals the circulation pipe 5. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
