摘要： A pump includes a pump casing that defines a pump chamber, the pump casing having an inlet and an outlet. An impeller is arranged with respect to the pump chamber to displace fluid from the inlet into the pump chamber. A vortex shaping mechanism is arranged in the pump chamber and is configured to constrain fluid within the pump chamber into a rotational flow pattern about a rotational axis. At least the casing and the vortex shaping mechanism are configured so that a portion of the fluid is encouraged to establish a solid body vortex, with an outer periphery of the solid body vortex being determined by the vortex shaping mechanism, and a portion of the fluid defining a diffusion zone in fluid communication with the outlet such that fluid can diffuse across a fluid interface between the solid body vortex and the diffusion zone to generate a pumping pressure at the outlet.

摘要： An apparatus for pumping or compressing a fluid comprises a housing, an inlet, an impeller, and an outlet. The housing has a front wall, a rear wall and side walls interconnecting the front and rear walls to define a fluid rotation chamber. The front and rear walls of the housing are substantially circular in plan view so that the housing is substantially cylindrical. The fluid rotation chamber is substantially square or rectangular in cross section along at least a portion of its axial length. The front and rear walls join the side wall with a curve having a radius of less than 10 mm for encouraging solid-body rotation of the fluid as a fluid vortex in the chamber and the rotation of the impeller causing fluid entering the apparatus through the inlet to rotate within the fluid rotation chamber prior to exiting the apparatus through the outlet. 13 -

摘要： Abstract An apparatus for pumping or compressing a fluid, the apparatus comprising: a housing having a front wall, a rear wall and one or more side walls 5 interconnecting the front and rear walls to define a fluid rotation chamber; at least one inlet located substantially centrally in the front wall; an impeller located at least partially within the at least one inlet such that at least a portion of the impeller extends outwardly beyond at least 10 a portion of the front wall; and at least one outlet, wherein rotation of the impeller causes fluid entering the apparatus through the at least one inlet to rotate within the fluid rotation chamber prior to exiting the apparatus through the at least one outlet.
