Abstract

1,271,807. Centrifugal and axial-How fans. SOC ANON DES ETABS NEU. Nov. 21, 1969 [Nov. 21, 1968], No. 57140/69. Heading F1C. In an adjustable stator blade assembly for creating pre-whirl of the inflow into a rotary fluid-flow machine, e.g. a centrifugal or axialflow fan, the stator blades (6), Fig. 2 (not shown), are each pivotally supported by a respective bearing (4) in a cylindrical housing 1 via a shaft 5, Fig. 1, rigidly attached to the blade and connected to a respective cam member 8, located in an arcuate slot 7 formed in, or in a member carried by, a rotatable and axially slidable ring 3. Thus, angular adjustment of the blades is achieved by rotating the ring 3 about the housing 1 as by a lever (9), Fig. 3 (not shown), rigidly attached to one of the shafts and pivoted on a pin 11. The blades may be arranged to fully close the flow passage through housing 1 when in their coplanar position, and to be angularly adjustable in either direction from that position. Alternatively, they may be adjustable in either direction from a fully open position, or be adjustable between fully closed and fully open positions. The ring 3 may be in surface-tosurface contact with housing 1 or mounted thereon via ball, roller or needle elements. The cam member 8 may be rigid or formed of resilient material or made up of a number of relativelymovable sections.
