Abstract
PURPOSE: To greatly decrease the noises due to gas supply, by making non-uniform the thickness of the peripheral part of an umbrella-shaped valve.
CONSTITUTION: A certain angle is set between the axis of the umbrella-shaped valve 1 and the normal to the conical surface 6 of the valve. The thickness of the conical part 6 is made different from that of the peripheral part 7. The thickness of the peripheral part 7 is made non-uniform. Thereby, a thick peripheral section 7b is opened with a very short lag time after a thin peripheral section 7a, and the vibration frequency of the peripheral part due to gas supply is reduced. The resonance of the whole umbrella-shaped valve 1 is prevented. Therefore, the noises are greatly decreased.
