Abstract
An accumulator (28), optionally in combination with an internal heat exchanger in a shared housing (24), comprising a cyclone (12) for separation of the gas and liquid phase of a refrigerant, and characterised in that the cyclone (12) comprises two separate, curved flow paths (14, 16), one of which (14) leads from an inlet (18) on the cover side whose direction of flow is closer to the axial than the radial direction of the cyclone (12) into the accumulator and radially outwards, and the other of which (16, 52) leads outwards from an end facing away from the cover (20).

-10. (canceled)
An accumulator in combination with an internal heat exchanger in a shared housing, the accumulator comprising:
- a cyclone for separation of a gas phase and a liquid phase of a refrigerant, wherein the cyclone further comprises:
- two separate, curved flow paths, a first one of the flow paths leads from an inlet on a cover side whose direction of flow is closer to an axial direction than a radial direction of the cyclone into the accumulator and radially outwards, and a second one of the flow paths leads outwards from an end facing away from a cover.
The accumulator according to claim 1, wherein the direction of flow of the cyclone at the inlet is within 45 degrees of the axial direction of the cyclone.
The accumulator according to claim 1, wherein at least one of the flow paths is spiral at least in some portions.
The accumulator according to claim 1, wherein an outlet of the first one of the flow paths of the cyclone forms the inlet of the accumulator and/or an outlet of the second one of the flow paths forms an outlet of the accumulator.
The accumulator according to claim 1, wherein the flow paths are separated from one another by a single partition.
The accumulator according to claim 1, wherein at at least one outlet, a partition is oriented substantially perpendicularly to an axis of the cyclone.
The accumulator according to claim 1, wherein the cyclone is produced from plastic.
The accumulator according to claim 1, wherein the cyclone is produced from a polymer.
The accumulator according to claim 1, wherein the cyclone is injection-moulded or printed in 3D.
The accumulator according to claim 1, wherein the cover has a single flow path for the refrigerant.
The accumulator according to claim 1, wherein the cover is produced in an asymmetric form.
