摘要

Improvements in devices for the regulation of the flow rate of centrifugal pumps, in which the suction inlet of the pump is communicated on the one hand with a suction chamber that is separated from the channel of conduction of the medium by means of an overflow edge, and also with an annular chamber communicating with the conduit channel through a tangential intake duct corresponding to the direction of rotation of the pump, characterized in that the aspiration chamber and the annular channel are created in a cylindrical vertical container, the upper edge of which it forms the overflow edge and in which the suction pipe of the pump penetrates from above, reaching the mouth of the tangential intake pipe to the container from its bottom to the overflow edge and penetrating as an open channel up the conduit channel .
