CENTRIFUGAL VANED MACHINE Russian patent published in 2015 - IPC F04D17/00 

FIELD: machine building.

SUBSTANCE: centrifugal vaned machine (100) contains a rotation axle (105), at least one impeller (106) with blades (107) installed on the rotation axle (105) and in casing (102) with at least one through channel (118), inlet and outlet branches (103), (104). The casing (102) is radially divided to at least two sectors I, II made by radial partitions. Sectors I, II comprise the suction chambers (108), (109) and discharge chambers (112), (113). Input of the suction chamber (108) of the first sector I is connected with input branch (103). Output of the discharge chamber (112) is connected by the through channel (118) with the suction chamber (109). Output of the discharge chamber (113) is connected with output branch (104). Unloading channel (122) is made in the casing (102), the channel is located between the suction chambers (108), (109). One end of the unloading channel (122) is connected with atmosphere or ejector installed in the input branch (103), and second end of the unloading channel (122) is located in the casing (102) with possibility of alternative connection with between blade channels (123) of the impeller (106).

EFFECT: centrifugal vaned machine has higher efficiency, and lower specific power is required for its drive.
