Abstract
PURPOSE: To reduce frictional force by such a construction that the valve disc is separated from the valve seat surface when the valve disc rotates.
CONSTITUTION: Flat surfaces 5a, 5b formed at the four corners of cam plates 6, 7 are in contact with the peripheral edge of a retainer ring 9 only when the valve is going to be opened and closed. When in contact the retainer ring 8 is moved forward by the pressure of a tray spring 9 to press the seat part 10 to the valve disc 5. Then the valve stem 3 turns the valve disc 5 in a certain direction to permit the circular surfaces of the cam plates 6, 7 to push aside the retainer ring 8 in contact with them, so that the seat part 10 is slightly separated from the periphery of the valve disc 5.
