Abstract

A housing of a liquid separation device that includes an inlet for the gas-liquid mixture and a set of integrated components, the set of integrated components includes a liquid separator vessel to separate liquid from the gas-liquid mixture, and the liquid separator vessel includes an entry port for the gas-liquid mixture, a liquid outlet port, and a gas outlet port. The set of integrated components includes a set of channels, where a wall of each channel is part of the housing, where the set of channels includes an inlet channel to guide the gas-liquid mixture from the inlet to the entry port and an outlet channel to guide gas from the gas outlet port away from the liquid separator vessel. The housing includes at least two opposite housing pieces which can be hermetically sealed together along a sealing line which is situated in a sealing face.

First claim

The invention claimed is:

1. A housing of a liquid separation device for separation of a liquid from a gas-liquid mixture, said housing comprising:
an inlet for the gas-liquid mixture;
at least two opposite housing pieces which are configured to be hermetically sealed together along a sealing line which is situated in a sealing face; and
a set of integrated components, said set of integrated components comprising a liquid separator vessel configured to separate liquid from the gas-liquid mixture, said liquid separator vessel comprising an entry port for the gas-liquid mixture, a liquid outlet port, and a gas outlet port,
wherein the set of integrated components further comprises a set of channels, wherein a wall of each channel is part of the housing,
wherein the set of channels comprises an inlet channel configured to guide the gas-liquid mixture from the inlet of the housing to the entry port of the liquid separator vessel;
and an outlet channel configured to guide gas from the gas outlet port away from the liquid separator vessel,
wherein the set of integrated components further comprises a liquid storage reservoir, said liquid storage reservoir being configured such that it is able to store liquid leaving the liquid separator vessel through the liquid outlet port of the liquid separator vessel, and
wherein an internal wall of the liquid storage reservoir comprises a recess configured to contain a heater.

2. The housing according to claim 1 , wherein the set of integrated components further comprises a liquid buffer tank, which liquid buffer tank is at least partly separated from the liquid separator vessel by means of a wall, and which liquid buffer tank is configured such that liquid in the liquid separator vessel is able to flow in the liquid buffer tank and vice versa through an opening in said wall.

3. The housing according to claim 1 , wherein the liquid separator vessel contains an internal liquid separation filter configured to further separate liquid from the gas-liquid mixture.

4. The housing according to claim 3 , wherein the set of channels comprises a scavenge channel which is configured to guide liquid separated in the internal liquid separation filter away from the liquid separator vessel.

5. The housing according to claim 1 , wherein the set of integrated components further comprises a supporting seat which is configured to be connected to the outlet channel and to accommodate an external liquid separation filter configured to further separate liquid from the gas-liquid mixture.

6. The housing according to claim 5 , wherein the set of integrated components further comprises a fitting configured to connect a blow-off valve and wherein the fitting configured to connect the blow-off valve is provided downstream the supporting seat configured to accommodate the external liquid separation filter.

7. The housing according to claim 1 , wherein the set of integrated components further comprises a fitting configured to connect a blow-off valve.

8. The housing according to claim 7 , wherein the liquid separator vessel contains an internal liquid separation filter configured to further separate liquid from the gas-liquid mixture and wherein the fitting configured to connect the blow-off valve is provided downstream the internal liquid separation filter.

9. The housing according to claim 1 , wherein the set of integrated components further comprises a fitting configured to connect a safety valve.

10. The housing according to claim 1 , wherein the set of integrated components further comprises a casing configured to contain a minimum pressure valve.

11. The housing according to claim 1 , wherein the sealing face is a plane.

12. The housing according to claim 1 , wherein a channel in the set of channels is cut along the sealing face over a distance of more than 50% of a length of said channel.

13. The housing according to claim 12 , wherein the sealing line is at least partly contained in the wall of the channel.

14. The housing according to claim 1 , wherein at least one of the at least two opposite housing pieces is provided with a groove along the sealing line.

15. The housing according to claim 14 , wherein the groove is a continuous groove.

16. The housing according to claim 14 , wherein at least one of the at least two opposite housing pieces opposite to the at least one of the at least two opposite housing pieces provided with the groove, is provided with a protrusion along the sealing line, said protrusion being configured to fit into the groove.

17. The housing according to claim 1 , wherein the liquid separator vessel comprises a detachable lid.

18. The housing according to claim 1 , wherein a channel in the set of channels is essentially constant in diameter along a length of said channel.

19. The housing according to claim 1 , wherein the liquid separator vessel comprises a concave internal surface which is cyclic symmetric.

20. The housing according to claim 19 , wherein the gas outlet port of the liquid separator vessel is arranged along an axis around which the concave internal surface is cyclic symmetric.

21. The housing according to claim 1 , wherein the gas outlet port and the liquid outlet port of the liquid separator vessel are arranged at a same side of the liquid separator vessel.

22. A housing of a liquid separation device for separation of a liquid from a gas-liquid mixture, said housing comprising:
an inlet for the gas-liquid mixture;
at least two opposite housing pieces which are configured to be hermetically sealed together along a sealing line which is situated in a sealing face; and
a set of integrated components, said set of integrated components comprising a liquid separator vessel configured to separate liquid from the gas-liquid mixture, said liquid separator vessel comprising an entry port for the gas-liquid mixture, a liquid outlet port, and a gas outlet port,
wherein the set of integrated components further comprises a set of channels, wherein a wall of each channel is part of the housing,
wherein the set of channels comprises an inlet channel configured to guide the gas-liquid mixture from the inlet of the housing to the entry port of the liquid separator vessel; and an outlet channel configured to guide gas from the gas outlet port away from the liquid separator vessel, and
wherein the set of integrated components further comprises a casing included in the housing and configured to contain a thermostatic valve.

23. The housing according to claim 1 , wherein the set of integrated components further comprises a supporting seat which is configured to accommodate a liquid filter configured to filter the liquid from impurities.

24. The housing according to claim 23 , wherein the set of channels comprises a drainage channel configured to drain liquid filtered from impurities in the liquid filter away from the supporting seat which is configured to accommodate the liquid filter.

25. The housing according to claim 22 , wherein the set of integrated components further comprises a supporting seat which is configured to accommodate a liquid filter configured to filter the liquid from impurities and wherein the set of channels comprises a connection channel configured to connect the casing configured to contain the thermostatic valve with the supporting seat configured to accommodate the liquid filter.
