ABSTRACT:
This invention is related to an arrangement in fans, compressors, turbines, pumps or the like, comprising at least one wheel, which is provided with vanes and through which a fluid is intended to pass at least partially in an essentially axial direction, and at least one inlet and one outlet opening. The main object of the invention is to improve this arrangement so that higher pressures may be obtained when used for driving a fluid and so that a better energy absorption from a fluid may be obtained when the fluid is driving the wheel. This object is achieved in that said wheel is arranged in a housing formed by a mantle provided at least partially about the periphery of the wheel and at least two side walls provided on opposite sides of the wheel, said housing and/or one or more parts associated therewith extending to the vicinity of the wheel on at least one side thereof.
