A centrifugal rotodynamic machine (100) comprises a rotation axis (105) and at least one rotor (106) with blades (107), which is mounted on the rotation axis (105) and is arranged in a housing (102) with at least one through passage (118), an inlet pipe (103) and an outlet pipe (104). The housing (102) is radially divided into at least two sectors I, II formed by radial partitions. The sectors I, II comprise intake chambers (108), (109) and delivery chambers (112), (113). The inlet of the intake chamber (108) of the first sector I is connected to the inlet pipe (103). The outlet of the delivery chamber (112) is connected by the through passage (118) to the intake chamber (109). The outlet of the delivery chamber (113) is connected to the outlet pipe (104). A relief passage (122) arranged between the intake chambers (108), (109) is formed in the housing (102). One end of the relief passage (122) is connected to the atmosphere or to an ejector, which can be mounted in the inlet pipe (103), and the other end of the relief passage (122) is arranged in the housing (102) so as to be able to alternately communicate with passages (123) between the blades of the rotor (106). The centrifugal rotodynamic machine is more efficient and a lower specific power is required for driving same. |
