Abstract (en)
The compressor stage of the turbo-blower consists of suction (13), a compressor wheel (1) attached to a shaft to which the compressor insert (5) is adjoined, installed into a spiral casing (4) (the insert may be an integral part of casing 4), whereby the compressor wheel (1), equipped with a greater number of blades is further linked to a bladeless part (2) of the diffuser followed by a bladed part (3) of the diffuser, where the compressor stage has a separated space for the passage of compressed gas and a space for the coolant, limited by the left side wall (6) and the right side wall (7) of the bladeless part (2) as well as of the bladed part (3) of the diffuser, followed by the right and left chambers ( 9 and 10 ), which are designed for the passage of the coolant fed or drained by the respective supply and drain connections ( 11 and 12 ) of the coolant in the respective supply and drain, whereby in this construction both the left and right chambers ( 9 and 10 ) are equipped with one respective supply and drain connection ( 11 and 12 ) of the respective supply and drain of the coolant.
