Description

원심 송풍기용 임펠러Impeller for Centrifugal Blower

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제3도는 본 발명에 의한 임펠러의부분 사시도.3 is a partial perspective view of an impeller according to the present invention.

제4a, 제4b도는 본 발명에서 깃을 중앙판에 부착하는 부착블럭의 제1형태의 사용을 도시하는 단면도이며,4A and 4B are cross-sectional views showing the use of the first form of the attachment block for attaching the feather to the center plate in the present invention,

제4a도는 임펠러축과 수직인 평면에 있으며 제4b도는 축을 포함한 평면에 있다.FIG. 4a is in a plane perpendicular to the impeller axis and FIG. 4b is in a plane including the axis.

Claims (15)
