ABSTRACT:
A flow controller of a temperature-sensitive type provided with an initial condition setting mechanism comprises a valve; a valve seat; a bimetal support tube disposed around the valve and adapted to be rotated and angularly positioned by operating means; a bimetal wound between the valve and the bimetal support tube, and having ends fixed to the valve and the bimetal support tube, respectively; and a liquid passage formed through the valve and connected to a space in which the bimetal is disposed. The valve includes a closing portion which has a passage port and the valve seat includes a port adapted to face to the closing portion including the port, so that the relative position between the ports changes for automatically control the flow by virtue of the rotation of the valve caused by deformation of the bimetal in accordance with the change of the liquid temperature.
