摘要： A regenerative or toric pump adds energy to a fluid using an impeller having an axis of rotation and axially spaced, radially extending first and second surfaces. A casing encloses the impeller and has a fluid inlet and a fluid outlet separated by a stripper. The casing has axially spaced, radially extending first and second sidewalls facing the first and second surfaces of the impeller respectively. Axially and radially extending blades or vanes are formed on an outer radial periphery of the impeller for driving fluid from the inlet toward the outlet as the impeller rotates about the axis of rotation. A fixed surface is formed in at least one sidewall of the casing for directing fluid back toward the impeller. Improved operating characteristics and extended range are accomplished through modification to the vane configuration of the impeller and/or by modification of the side channel configuration of the pump chamber in an asymmetrical fashion. The vanes can be modified to include a radially inward based portion extending in a generally trailing direction with respect to rotation of the impeller and a radially outward tip portion extending in a generally leading direction. The blades may also include a chamfered surface on the trailing edge of the base portion. The impeller chamber can be modified separately by expanding a side channel in the casing, or by insertion of a spacer between the side channel and the remaining portion of the casing defining the impeller chamber.

摘要： A regenerative fluid dynamic machine, typically a blower or compressor, includes an impeller (1) with fixedly attached blades (6) which may be radial or curved in a general convex fashion facing forward in the direction of turning. The impeller is enclosed in a housing which, together with the shaped profile of the rotor flank/s defines a toroidal passage (7) between inlet an outlet ports, fluid flow in said passage/s following a path which forms a spiral centred generally within the cross section of the passage, said housing may be provided with slideable side walls that are made to contact and expand the width of said toroidal passage to change the operation of the compressor so as to meet the requirements of fluid delivery or pressure. A preferred option is also proposed that will achieve a superior result through variations to the circumference span of the inlet passage.
