摘要： A fan end bracket (14) for a motorized fan assembly has a plurality of curvilinear tapered air passages (29). Each air passage includes a flow port (30) such that air being moved by a rotating fan assembly is directed through the air passages and the flow ports. A skeletal motor assembly (12) is affixed to one side of the end bracket such that the motor shaft (16) is disposed through a shaft aperture in the end bracket. A rotating fan member (15) is affixed to the motor shaft adjacent to the other side of the end bracket. A shroud member (19) is provided to shroud the rotating fan member so as to cause the flow of air to be directed through the air passages. A baffle plate (18) is interposed between the rotating fan member and the end bracket. The baffle plate includes a plurality of curvilinear scallops (40) which correspond to the air passages in the end bracket. An effective flow port is created between the scallops of the baffle plate and the tapered ramp surfaces (28) of the end brackets so the size of the effective flow port may be adjusted by merely changing the baffle plate so as to optimize the flow and pressure parameters of the fan for a particular motor size.

摘要： A gas turbine engine with first and second axial flow compressors and an intercooler therebetween is provided with a bend diffuser (16) and a radial flow diffuser (18) to diffuse the air leaving the downstream end (38) of the first axial flow compressor (14) at a first radial distance (R₁) from the axis to the upstream end of the intercooler at a second radial distance from the axis . The bend diffuser (16) comprises a first radially outer wall (54) and a second radially inner wall (56). The first wall (54) is elliptical and the second wall (56) has a profile derived from a relationship between the local area ratio and the path length around the arc such there is rapid diffusion in the bend diffuser (16) without fluid flow separation from the first wall (54).

摘要： At a vaned diffuser or a volute casing of a centrifugal fluid machine, pressure pulsation and vibrating forces acting upon the diffuser or the volute casing are mitigated or cancelled so as to abate the noise from the centrifugal fluid machine. The fluid machine having an impeller 3 rotating about a rotating shaft 2 within a casing 1 and having a vaned diffuser 4 or volute 12 fixed to the casing 1 is constructed such that radius of the vane trailing edge of the impeller 3 and radius of the vane leading edge of the diffuser 4 or radius of the volute tongue is varied in the direction of axis of rotation and inclinations, on a meridional plane, of the vane trailing edge of the impeller 3 and the vane leading edge of the diffuser 4 or the volute tongue are set in the same orientation, thereby reduction in head and efficiency or occurrence of an axial thrust may be restrained to the extent possible to optimally abate the noise and pressure pulsation of the centrifugal fluid machine.

摘要： Die Warenbahn (1) wird durch aufgeheizte Umluft beaufschlagt, welche mit Hilfe eines Gebläses (7) von einem Druckraum (14) über Eintrittsöffnungen (6, 6') in Düsenkästen (4, 4') eindringt. Um eine laminare Strömung und damit eine bessere Luftverteilung zu erzielen, ist das Gebläse (7) soweit wie möglich von den Eintrittsöffnungen (6, 6') entfernt und vorzugsweise unterhalb der Deckenwand (16) des Gehäuses (2) aufgehängt. Dies ergibt einen relativ grossen und langgestreckten Druckraum (14) zwischen den Eintrittsöffnungen (6, 6') und der Druckseite (12) des Gebläses (7).

摘要： A collector for a vaned diffuser in a centrifugal compressor, wherein the radial cross-sectional area of the collector housing at the entrance to the collector outlet duct is 40% to 80% of the entrance area of the outlet duct (32) and progresses smoothly to the outlet duct entrance area. Progression in collector housing cross-sectional area is produced by variation of the collector axial height. At the intersection with the outlet duct, the collector has a step in axial height so as to at least partially direct circumferential flow from the collector into the outlet duct entrance.

摘要： An assembly for use in domestic and commercial vacuum cleaners comprises an air guide (25) attached to a motor housing. The end of the motor housing adjacent the air guide (25) comprises a bracket (24) that cooperates with centre details (43) on the air guide (25) to retain the latter in position on the motor housing. The bracket (24) has a central aperture (59) which accommodates a motor bearing (55). In use the shaft (31) of an electric motor (21) in the housing with brackets (24), projecting through the bearing (55) and a central aperture (45) in the air guide (25), drives a centrifugal fan (26). The air guide (25) has a plurality of fixed spiral vanes (36) extending from the inlet ports (38) located on the side adjacent the centrifugal fan (26), to its outlet ports on the reverse side adjacent the bracket (24). In one embodiment, the air guide (25) has apertures (47) for receiving rivets (61) that fasten the air guide (25) to the motor housing, extending through the bracket (24) to hold the motor bearing (55) in position.
