Abstract (en)
[origin: EP1930601A2] There is described a scroll type manifold which is intended to constitute the housing of an impeller (2) of a fan, comprising a pair of half-shells (4, 5) which can be connected to each other in a connection plane (P), each half-shell (4, 5) including a respective portion (4a, 5a) of a delivery nozzle (6) of the manifold, the nozzle portions together defining the delivery cross-section (3) of the manifold. The manifold half-shells (4, 5) are articulated to each other about an articulation axis (Z), so as to be mutually pivotable between a first operating position, in which the half-shells (4, 5) are connected along the connection plane (P) and the nozzle portions (4a, 5a) delimit the entire delivery cross-section (3), and a second operating position, in which the nozzle portions (4a, 5a) are moved towards each other with a consequent reduction in the extent of the delivery cross-section (3).
