Summary:PURPOSE:To decrease the discharge pressure loss by forming stationary and revolving vortex bodies with an outside curve and an inside curve made of an involute curve and a connection curve having a circular arc respectively. CONSTITUTION:An outside curve 1111 is made of an involute curve with a radius (b) and a starting point A, and an inside curve 1112 is made of an involute curve with a radius R and a circular arc. a connection curve 1113 is made of a circular arc with a radius (r) for connection between the outside curve 1111 and inside curve 1112. The curve between H and J of the inside curve 1112 is constituted so as to approach the outside curve 1111. Accordingly, the discharge pressure loss can be largely decreased.
