Abstract

A separator (10) comprises a housing (12) and a separator chamber (24) contained within the housing, an inlet (26) and outlet (28) to the separator chamber and a dividing member (34) for substantially dividing the separator chamber into a first chamber (30) and a second chamber (32). A flow path (38) is provided between the first and second chambers for allowing flow to circulate between the first and second chambers, and guide means (56) for creating opposing flow paths in the second chamber (32) for slowing flow through the second chamber (32).

Claims

1. A separator comprising a housing, a separator chamber contained within the housing, an inlet and outlet to the separator chamber, a dividing member for substantially dividing the separator chamber into a first chamber and a second chamber, a flow path provided between the first and second chambers for allowing flow to circulate between the first and second chambers, and a flow guide for creating opposing flow paths in the second chamber, the opposing flow paths meeting in an area of the second chamber where the flow in each path is substantially towards opposing flow in the other path, for slowing flow through the second chamber,

in which arrestor elements are provided in the second chamber for slowing flow,

in which the arrestor elements include a plurality of pins, and

in which at least one of the pins extends through an aperture in the dividing member into the first chamber.

2. A separator as claimed in claim 1, in which a magnet is provided in the first chamber.

3. A separator as claimed in claim 2, in which a tubular sleeve is provided around the magnet.

4. A separator as claimed in claim 3, in which the tubular sleeve is mounted to the dividing member and extends longitudinally along a central axis of the first chamber.

5. A separator as claimed in claim 4, in which the dividing member and tubular sleeve are removable for cleaning.

6. A separator as claimed in claim 1, in which co-operating locating formations are provided on the dividing member and housing respectively, for positioning the dividing member within the housing.

7. A separator as claimed in claim 1, in which an aperture is provided through the dividing member and a flow guide is positioned adjacent the aperture for directing flow through the aperture from the first chamber to the second chamber.

8. A separator as claimed in claim 7, in which the aperture is a substantially radial slot.

9. A separator as claimed in claim 7, in which a guide wall is provided in the second chamber for directing flow entering the lower portion through the aperture in the dividing member.

10. A separator as claimed in claim 9, in which a space is provided between the upper end of the guide wall and the underside of the dividing member, in use, flow passing in one direction over the top of the wall and being directed in the opposite direction by the wall.

11. A separator as claimed in claim 7, in which at least a second aperture is provided through the dividing member, the second aperture being around 120 degrees angularly displaced from the first aperture, behind the flow guide.

12. A separator as claimed in claim 11, in which the second aperture is smaller than the first aperture.

13. A separator as claimed in claim 1, in which the pins extend parallel with a central longitudinal axis of the separator.

14. A separator as claimed in claim 1, in which the arrestor elements include one or more walls.

15. A separator as claimed in claim 14, in which each wall extends from one of the pins.

16. A separator as claimed in claim 1, in which a bleed valve for releasing pressure from the separator and a dosing point for adding liquid to the separator are provided in a single fitting.

17. A separator comprising a housing, a separator chamber contained within the housing, an inlet and outlet to the separator chamber, a dividing member substantially dividing the separator chamber into a first chamber and a second chamber, a flow path provided between the first and second chambers for allowing flow to circulate between the first and second chambers, and a flow guide for creating opposing flow paths in the second chamber, the flow guide including a reversing portion adapted to change the direction of a portion of the flow impinging on the flow guide and a bypass portion allowing passage past the flow guide of a further portion of the flow, without change of direction of the further portion,

in which arrestor elements are provided in the second chamber for slowing flow,

in which the arrestor elements include a plurality of pins, and

in which at least one of the pins extends through an aperture in the dividing member into the first chamber.
