The separator assembly comprises a housing having a head part which provides the upper end of the housing and a body part which provides the lower end of the housing. The separator assembly also comprises a shield which extends across the housing towards the lower end thereof so as to leave a collection space between it and the lower end in which material that is separated from the gas stream can collect. There is at least one opening in or around the shield through which the material can flow past the shield into the collection space. The separator assembly further comprises a liner sleeve which covers at least a part of the inside wall of the body part between the shield and the upper end of the body part.
c. a liner sleeve which covers at least a part of the inside wall of the body part between the shield and the upper end of the body part, the liner sleeve having an inner side wall with an imperforate surface, in which the surface of the inner side wall of the liner sleeve has formations which reduce the tendency of liquid to cling to the surface of the inner side wall of the liner sleeve.
4. A separator assembly as claimed in claim 1, in which the texture of the surface inner side wall of the liner sleeve is rough.
5. A separator assembly as claimed in claim 1, in which the inner side wall of the liner sleeve has grooves on its surface.
6. A separator assembly as claimed in claim 1, in which the inner side wall of the liner sleeve has a helically extending rifle formation on its surface.
7. A separator assembly as claimed in claim 1, in which the liner sleeve is provided as part of the shield as a wall that extends around the perimeter of the shield on the face of the shield which is directed toward the upper end of the housing, so that the shield and the liner sleeve can be removed from the housing as one piece.
8. A separator assembly for removing material that is entrained in a fluid stream comprising:
c. a liner sleeve which covers at least a part of the inside wall of the body part between the shield and the upper end of the body part, the liner sleeve having an inner side wall with an imperforate surface in which the surface of the inner side wall of the liner sleeve has formations which reduce the tendency of liquid to cling to the surface of the inner side wall of the liner sleeve.

A separator assembly as claimed in claim 8, in which the liner sleeve is provided as part of the shield as a wall that extends around the perimeter of the shield on the face of the shield which is directed toward the upper end of the housing, so that the shield and the liner sleeve can be removed from the housing as one piece. Description
CROSS REFERENCE TO RELATED APPLICATIONS This application is continuation of copending International Application No. PCT/GB06/002727 filed Jul. 21, 2006, which designated the United States, the disclosure of which is incorporated herein by reference, and which claims priority to Great Britain Patent Application Nos. 0524181.5 filed Nov. 28, 2005; and 0515266.5, filed Jul. 26, 2005.
BACKGROUND OF THE INVENTION The present invention relates to a separator assembly for removing material that is entrained in a gas stream such as liquid in an aerosol form.
SUMMARY OF THE INVENTION Removal of material from a gas stream can be required to ensure that the gas is sufficiently clean for a subsequent application, or to minimise adverse effects of impurities on components of the system. For example, removal of compressor oil can be required to minimise chemical contamination and accumulation on valves which might lead to malfunction of the valves, and removal of particulate solid material can be required to minimise abrasion. Also, removal of liquid such as water droplets from a gas stream can be required in order to minimise contaminant loading in downstream filters.
Preferably, the assembly also includes a second flow deflector so that gas flowing into the housing flows over the second flow deflector so that the incoming gas is forced toward the side walls of the housing. Preferably, the second flow deflector is located downstream of the first flow director, so that the gas stream flowing into the housing flows over the first flow director first, and then flows over the second flow deflector. Accordingly, preferably, the second flow deflector is located on the side of the flow director that is distal to the inlet port.
Preferably, the second flow deflector is fastened to the outlet tube. The flow deflector and the outlet tube can be provided as a single piece. For example, the second flow deflector and the outlet tube can be created from a single mould. This can enable easy manufacturing and putting together of the assembly. The second flow deflector and the outlet tube can be provided as separate pieces, which can be fastened together. This can allow different flow deflector to be used with different outlet tubes.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, FIG. 1 shows a separator assembly 2, which comprises a housing 4 defining an inner volume 6. The housing 4 comprises a head part 12, and a body part 14 which can be connected to one another by means of cooperating screw threads at their interfaces 16, 18. The housing 4 further comprises inlet 20 and outlet 22 ports located in the head part 12, for gas to enter and exit the separator assembly 2, a reservoir 8 located at a second end of the housing opposite the first end, and a liquid drainage port 10. The separator assembly further comprises a first flow director 24, a second flow deflector 26, a shield 28, a second flow conduit device 30 which includes a conduit portion 32, all located within the body part 14 of the housing 4.
The separator assembly 2 can be disassembled by rotating the housing head part 12 and body part 14 relative to each other so that their cooperating screw threads are loosened. Any rotational force that is imparted on the flow conduit device 30 by frictional and related forces (for example arising from physical or chemical interactions or both) between the O-ring 78 on the flow conduit device and the primary chamber 44 of the head part 12 is negated by the opposite rotational drive that is provided by the ribs 70 acting against the grooves 92 in the shield wall 28. Therefore, as the housing head part 12 and body part 14 are rotated relative to each other, the flow conduit device 30 will tend to reside in the body part rather than be drawn away from the body part with the head part. Accordingly, when the head part 12 and the body part 14 are separated from each other, the flow conduit device 30 will remain located within the body part 14.
In use, the separator assembly is used in a substantially vertical position, with the housing head part 12 being above the body part 14. A gas having an entrained material that is to be removed from the gas enters the separator assembly through the inlet port 20. In the embodiment described, the gas is air and the material is water. The air flows away from the inlet port 20, and passes over the baffles 72 of the flow director 24. The configuration and arrangement of the baffles 72 impart a helical flow to the gas stream as illustrated by line 85. Once the gas has passed through the first flow director 24, over the baffles 72, the gas then flows over the second flow deflector 26. The configuration and arrangement of the flow deflector 26 forces the gas to flow outwards towards the shield wall 28.
