ABSTRACT:
A flow rate control valve including a valve chest having an open end, an inflow passage and outflow passage each having one end communicating with the valve chest and the other end opened, a valve seat provided at the end of the inflow passage or outflow passage communicating with the valve chest, a sheet-like diaphragm provided to tightly close the open end of the valve chest and a stacked-type displacement device made of an electromechanical transducing material exhibiting the maximum value of piezoelectric distortion constant at a higher temperature range than 100.degree. C. or above and which exerts a pressure on the diaphragm by its deformation to change the position of the diaphragm, thereby controlling the gap between the valve seat and the diaphragm.
