摘要	PURPOSE: To improve controlling characteristics and responsiveness by forming an inner lug and an outer lug brought into contact with the inside and outside of a fluid passage respectively on a valve plug head section. CONSTITUTION: A valve plug 10 is constituted with a valve plug head section 10a opening/closing a fluid passage 9 by being brought into contact with or removed from a valve seat section surface 4a and a valve plug barrel section 10b connected to a thermally expandable member 13 as a valve plug driving section. An annular, inner lug 14 and an outer lug 15 brought into contact with the valve seat section surface 4a respectively at the inside and outside of the fluid passage 9 are formed on the surface of the valve plug head section 10a near the valve seat section surface 4a. A fluid flows in from both the outside and inside at the inflow side of the fluid passage 9, thus the flow control range is increased. COPYRIGHT: (C)1987,JPO&Japio
