<p><P>PROBLEM TO BE SOLVED: To provide a temperature sensitive valve with a cleaning function for easily and reliably cleaning and removing scales deposited and accumulated on a valve port portion. <P>SOLUTION: The temperature sensitive valve comprises a body 1 having a fluid inlet 1a and a fluid outlet 1b, a valve seat member 4 having a valve port 41, a valve element 51 for opening/closing the valve port 41, and a temperature sensitive driver 7 for driving the valve element 51 in response to the temperature of fluid. Herein, a cleaning tool 100 is provided which is supported on the body 1 retractably in the direction of the axial center corresponding to the moving direction of the valve element 51. When rotated around the axial center at a moving position, it scuffs on an inner peripheral face 11b of a communication passage 11 ranging to the valve port 41 of the valve seat member 4 for cleaning the scales S2 causing clogging, deposited and accumulated on the inner peripheral face 11b. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
