Abstract (en)
[origin: EP0928899A2] A once-through blower including a once-through impeller (8) is described. The blower includes a blowout duct (10), a stabilizer (13) and a scroll casing (9). The stabilizer (13) provided at an end of the blowout duct (10) so as to face the once-through impeller (8). The scroll casing (9) is provided at the back of the once-through impeller (8) and connected to the blowout duct (10). The stabilizer (13) has a curved surface (18) which is formed along an arc (15). The diameter of the arc (15) is 103% or more of that of the once-through impeller (8). The scroll casing (9) has an interior curved surface (19) which is formed along a casing arc. The casing arc is concentric with the arc center (21). A clearance between a predetermined outer peripheral point (23) of the once-through impeller (8) and the inflow-side end of the scroll casing (9) is set so as to become 3% or more of the diameter of the once-through impeller (8). <IMAGE>
