Abstract
An apparatus for converting rotation into fluid flow and/or fluid flow into rotation. The apparatus comprises a first stage including a coiled fluid conduit having an inlet and an outlet, a first fluid separator configured to receive batches of first fluid and batches of second fluid from the outlet of the coiled fluid conduit of the first stage and separate the first fluid and the second fluid, a second stage including a coiled fluid conduit having an inlet and an outlet, and a first interstage flow channel connecting the first fluid separator with the inlet of the coiled fluid conduit of the second stage for providing first fluid to the inlet of the coiled fluid conduit of the second stage.
Claims15
An apparatus for converting rotation to fluid flow, comprising:
- a first stage including:
- a coiled fluid conduit of the first stage having an inlet for receiving gaseous first fluid having a first density and liquid second fluid having a second density higher than the first density, and an outlet, the coiled fluid conduit of the first stage being arranged to transport batches of the first fluid and batches of the second fluid towards the outlet of the coiled fluid conduit of the first stage when the coiled fluid conduit of the first stage rotates around a rotational axis, while pressurizing the first fluid and the second fluid to provide a pressure differential between the outlet and the inlet;
- and
- a first fluid separator of the first stage configured to receive the batches of the first fluid and the batches of the second fluid output from the outlet of the coiled fluid conduit of the first stage, and separate the first fluid and the second fluid;
- a second stage including:
- a coiled fluid conduit of the second stage having an inlet for receiving first fluid and second fluid, and an outlet, the coiled fluid conduit of the second stage being arranged to transport batches of the first fluid and batches of the second fluid towards the outlet of the coiled fluid conduit when the coiled fluid conduit of the second stage rotates around the rotational axis, while pressurizing the first fluid and the second fluid to provide a pressure differential between the outlet and the inlet;
- and
- a first fluid separator of the second stage configured to receive the batches of the first fluid and the batches of the second fluid output from the outlet of the coiled fluid conduit of the second stage, and separate the first fluid and the second fluid;
- and
- a first interstage flow channel connecting the first fluid separator of the first stage with the inlet of the coiled fluid conduit of the second stage for providing first fluid to the inlet of the coiled fluid conduit of the second stage.

An apparatus for converting fluid flow to rotation around a rotational axis, comprising:
- an apparatus inlet for receiving gaseous pressurized first fluid having a first density;
- an apparatus outlet for output of depressurized first fluid from the apparatus;
- a first stage including:
- a coiled fluid conduit for accommodating transport of alternating batches of the first fluid and batches of a liquid second fluid having a second density higher than the first density from an inlet of the coiled fluid conduit of the first stage in fluid communication with the apparatus inlet towards an outlet of the coiled fluid conduit of the first stage when the coiled fluid conduit of the first stage rotates around the rotational axis, while depressurizing the first fluid and the second fluid to provide a pressure differential between the outlet and the inlet of the coiled fluid conduit of the first stage;
- and
- a first fluid separator of the first stage configured to receive the batches of the first fluid and the batches of the second fluid output from the outlet of the coiled fluid conduit of the first stage, and separate the first fluid and the second fluid;
- a second stage including:
- a coiled fluid conduit of the second stage for accommodating transport of alternating batches of the first fluid and batches of the second fluid from an inlet of the coiled fluid conduit of the second stage towards an outlet of the coiled fluid conduit of the second stage when the coiled fluid conduit of the second stage rotates around the rotational axis, while depressurizing the first fluid and the second fluid to provide a pressure differential between the outlet and the inlet of the coiled fluid conduit of the second stage;
- and
- a first fluid separator of the second stage configured to receive the batches of the first fluid and the batches of the second fluid output from the outlet of the coiled fluid conduit of the second stage, and separate the first fluid and the second fluid;
- and
- a first interstage flow channel connecting the first fluid separator of the first stage with the inlet of the coiled fluid conduit of the second stage for providing first fluid to the inlet of the coiled fluid conduit of the second stage.
