Apparatus and a method for regulation of the energy potential in a fluid column located within a pipeline
First Claim
1. An apparatus for use in controlling a differential pressure between a fluid column upstream and downstream of the apparatus, said apparatus comprising at least two impellers, each having a rotatable shaft provided with a plurality of vanes or blades, the impellers being disposed in a housing which constitutes a portion of a pipeline, said shafts communicating with a load, said apparatus is arranged for receiving the fluid column between the shafts of the impellers, whereby the velocity of the fluid column through the apparatus substantially corresponds to the velocity of the fluid column immediately adjacent to the impellers of the apparatus, and the impellers of the apparatus are arranged for providing a rotatable barrier for the fluid column in that at least one of the vanes or blades of each of the impellers is in substantially sealing contact with a first portion of the internal jacket surface of the housing, said barrier being influenced by said load to provide any predetermined differential pressure between the fluid column upstream and downstream of the apparatus,wherein at least one of the blades of each of the impellers is constantly in substantially sealing contact with an elongated dividing element which is disposed in a portion of the apparatus, said dividing element providing a partition between the impellers and extending past a straight line through said shafts.

Abstract
The present invention describes an apparatus (1) and a method for use in regulation of the energy potential in a fluid column located within a pipeline (13), the apparatus (1) including two impellers (2), either one including a rotatable shaft (6) which is provided with a plurality of vanes or plate-shaped blades (8), the impellers (2) being disposed in a housing (4) which constitutes a portion of the pipeline (13), the apparatus (1) communicating with a load (19, 21) and/or an energy source, so that the impellers (2) of the apparatus (1) are arranged to influence the movement of the fluid column within the pipeline (13), the apparatus (1) being arranged to receive the fluid column between the shafts (6) of the impellers (2), the centre axis of said shafts (6) being substantially in the same plane as wall portions of the housing (4) upstream and downstream of the vanes, whereby the rate of the fluid column through the apparatus substantially corresponds to the rate of the fluid column immediately upstream and/or downstream of the impellers (2) of the apparatus (1).

6. A method for controlling a differential pressure in a fluid column located within a pipeline, said method comprising:
-
integrating in the pipeline an apparatus which includes at least two impellers, either one comprising a rotatable shaft provided with a plurality of vanes or blades, disposing the impellers in a housing which constitutes a portion of the pipeline, said shafts communicating with a load, whereby the velocity of the fluid column through the apparatus substantially corresponds to the velocity of the fluid column immediately adjacent to the impellers of the apparatus, and the impellers of the apparatus are arranged for providing a rotatable barrier for the fluid column in that at least one of the vanes or blades of each of the impellers is in substantially sealing contact with a first portion of the internal jacket surface of the housing, said barrier being influenced by said load to provide any predetermined differential pressure between the fluid column upstream and downstream of the apparatus; and controlling the rotation of said impellers by the load communicating with the shafts of the impellers to provide any predetermined differential pressure between the pressures of the fluid column upstream and downstream of the apparatus. - View Dependent Claims (7, 8, 9, 10)
