A radial turbine, compressor or pump and the like comprising: a housing; a rotatable shaft; a fluid inlet and a fluid outlet in said housing; a stator through which said fluid flows in said housing; a fluid rotor connected to said shaft in said housing; a plurality of diffuser vanes in said stator whose disposition may be modulated to control the fluid flow through said stator, each diffuser vane being generally radially oriented and pivotable about an axis which is spacially maintained in a fixed relationship relative to the rotatable shaft and extends parallel thereto; and operative means providing a substantially clearance free, self-locking mechanism modulating the disposition of said diffuser vanes, said operative means comprising a plurality of circumferentially arranged vane control links, each link being connected to a diffuser vane and each link being pivotable about the fixed pivotable axis of the respective diffuser vane and having a pair of spaced, radially directed cam followers, cam means including a pair of cam rings having circumferential cam surfaces engaged by said followers, and means to move said cam means relative to said followers to pivot each diffuser vane about its fixed axis and change the radial position thereof.
