Abstract

PURPOSE: To positively start and stop a ventilating fan, by operating a reed switch in response to a relief valve.
CONSTITUTION: When water is let pass through a water supply passage 1, an opening-and-closing valve 14 is opened through a functioning lever 15 because a diaphragm 8 is subject to water pressure and left moved, thus fuel is fed to a combus- tor 5 and burnt. Meanwhile, a rod 16 is left locomoted by means of a spring 17 because a relief valve 11 is also shifted left against the force of a spring 13 with the left movement of the diaphragm 8, thus a lead switch 19 reaches a closing region. That is, a ventilating fan is started becasue the lead switch 19 is closed. Since the rod 16 keeps distance l4, which does not damage a control condition of the relief valve 11, under this condition and parts from the relief valve 11, there is no danger that the relief valve 11 gives force causing trouble for controlling water supply pressure. Since a pressure receiving diameter of the rod 16 is small, force for open- ing the lead switch 19 can sufficiently be opposed by means of the spring 13 by the water supply pressure.
