<p><P>PROBLEM TO BE SOLVED: To intermittently emit a jet of high energy such as a high pressure, high flow rate or high speed jet from a nozzle in relation to a fluid jet device provided with a heat exchanger heating cool water to hot water for washing a human body or the like. <P>SOLUTION: An interlocking means 26 interlocking action of a variable flow passage area means 22 varying area of a flow passage in a downstream of a pump 20 and action of the pump 20 is provided. Consequently, the jet of large energy such as the high pressure, high flow rate or high speed jet can be emitted intermittently by tentatively accumulating and releasing pressure of fluid pressurized by the pump 20 in an upstream side of the variable flow passage area means 22. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
