<P>PROBLEM TO BE SOLVED: To provide an ejector preventing a valve element from becoming immovable relative to a body due to freeze ice during an operation stop. <P>SOLUTION: This ejector 18 sucks a second gas by the flow of a first gas, mixes the first gas with second gas, and delivers the mixed gas. The body 40 of the ejector 18 is formed with a gas passing port 52 for allowing at least one of the first gas and second gas to flow. The valve element 60 is disposed advancingly and retreatingly with respect to the gas passing port 52, and the valve element 60 changes the gas passing area of the gas passing port 52. The heat capacity of material forming the valve element 60 is higher than the heat capacity of material forming the body 40. <P>COPYRIGHT: (C)2010,JPO&INPIT |
