DEVICE TO CREATE FLOW IN GASES AND FLUIDS Russian patent published in 2014 - IPC F04D33/00 

FIELD: engines and pumps.

SUBSTANCE: set of inventions can be used as blowers, pumps and propulsors for aircraft, ships and submarines. Device comprises drive shaft, blades and housing composed by hollow parallelepiped with two flat walls connected by hemispherical walls with inlet and outlet. Inner walls with cut-outs connected with hemispherical walls are arranged along the edges of said inlet and outlet. Blades shafts are fitted in chains or belts running over drive and driven sprockets or pulleys fitted on the shaft and axle, respectively, inside hemispherical walls. Blade shafts extend via guide cut-outs of inner walls. The latter separate the flexible gearing from blades, their shafts extending through inner wall guide cut-outs to engage with bushes of chins or belts and having yokes with two teeth fitting in guide grooves made at flat wall inner side. Grooves nearby inlet and outlet are shaped top two parallel slots to merge nearby sprocket or pulley so that one slot results shaped to hemisphere.

EFFECT: simplified design, higher reliability, lower costs.
