摘要： Since a throttle hole (14) for narrowing a scavenging passage is provided on a partition (13) for closing the scavenging passage, the throttle hole (14) of a desired size can be drilled at a desired location on the partition (13) after preparing the scavenging cover (11) having no throttle hole (14) on the partition (13). Accordingly, the size and location of the throttle hole (14) can be easily changed in conducting a test for finding the most appropriate size and location of the throttle hole (14), so that the most appropriate size and location of the throttle hole can be easily found.
摘要翻译：由于用于使清扫通路变窄的节流孔（14）设置在用于关闭扫气通道的隔板（13）上，所以可以在分隔件（13）上的所需位置上钻出所需尺寸的节流孔（14）准备在隔板（13）上没有节流孔（14）的扫气罩（11）。因此，在进行用于找到最适当的节流孔（14）的尺寸和位置的试验中，可以容易地改变节流孔（14）的尺寸和位置，使得节流孔的最合适的尺寸和位置可以容易找到。
