Abstract
Abstract A centrifugal fluid vanes compressor for compressing an effluvium is described, which comprises a compression chamber bounded by two parallel walls between which the fluid vanes are rotating, which vanes are formed by a flowing fluid which emerges at a high velocity through jet openings in a rapidly rotating driven rotor. The compressed effluvium is discharged and the fluid of the fluid vanes is collected in a fluid reservoir and recycled via a pump. An improved fluid vanes compressor is described in which the fluid entrance opening of the rotor is situated substantially in the same circumferential plane of the rotor as the discharge openings of the jets. As a result of these measures the relative rate of discharge of the fluid from the jet openings is substantially equal or little lower than the local circumferential speed of the rotor which results in a considerable improvement in efficiency.

Claim 1
Independent Claim
204 words
A centrifugal fluid vanes compressor for compressing a gaseous medium comprising: a compression chamber having a central inlet for a gas; a driven rotor disposed generally in the center of the compression chamber; said compression chamber having a pair of spaced walls disposed on opposite sides of the rotor and extending radially outwardly away from the rotor; said rotor being provided with vanes for suction of gas through the central inlet and having jet channels extending therethrough; a fluid supply duct including a fluid pump connected to the jet channels of the rotor; a fluid reservoir in open communication with the compression chamber and connected with the fluid pump, said reservoir having a discharge pipe for the compressed gas; said jet channels having inlet ends which are situated in substantially the same circumferential plane as the outlet ends of said jet channels, said inlet ends of the jet channels being surrounded by an annular fluid chamber connected to said fluid supply duct and having an outlet opening situated opposite said inlet ends of the jet channels, said outlet opening of the annular chamber being provided with guiding blades directed substantially tangentially with respect to the periphery of said rotor in itS direction of rotation.
