FILTER ASSEMBLY AND FILTER ELEMENT FOR USE IN THE ASSEMBLY
First Claim
1. A filter assembly for collecting material that is entrained in a fluid stream, the assembly including:
- a removable filter element having a tubular filter through which, in use, the fluid stream flows, and an end cap providing a flow conduit which extends between a first conduit opening and a second conduit opening communicating with the internal void of the tubular filter, the axis of the first conduit opening being at an angle to the axis of the tubular filter; and
a housing for the filter element, the housing having inlet and outlet ports for the fluid stream, a housing bowl in which the tubular filter is located, and a housing head which provides at least one of the ports as a docking port for the first conduit opening;
wherein the housing head and the end cap are arranged such that the end cap is inserted into the housing head, and then rotated relative to the housing head about an axis perpendicular to the axis of the tubular filter and to the axis of the first conduit opening to bring the first conduit opening and the docking port into sealed communication.

Abstract
A filter assembly for collecting material entrained in a fluid stream includes a filter element having a tubular filter and an end cap providing a flow conduit which extends between first and second conduit openings communicating with the internal void of the tubular filter. A housing for the filter element has inlet and outlet ports for the fluid stream, a housing bowl in which the tubular filter is located, and a housing head which provides at least one of the ports as a docking port for the first conduit opening. The housing head and end cap are arranged such that the end cap is inserted into the housing head, and then rotated relative to the housing head about an axis perpendicular to the axis of the tubular filter and to the axis of the first conduit

11. A filter element for collecting material that is entrained in a fluid stream, the filter cartridge having a tubular filter through which, in use, the fluid stream flows, and an end cap providing a flow conduit which extends between a first conduit opening and a second conduit opening communicating with the internal void of the tubular filter, the axis of the first conduit opening being at an angle to the axis of the tubular filter;
-
the filter element being arranged for use with a housing for the filter element, the housing having inlet and outlet ports for the fluid stream, a housing bowl in which the tubular filter is located, and a housing head which provides at least one of the ports as a docking port for the first conduit opening, in use the end cap being inserted into the housing, and then rotated relative to the housing head about an axis perpendicular to the axis of the tubular filter and to the axis of the first conduit opening to bring the first conduit opening and the docking port into sealed communication; wherein the end cap has a projecting portion which slidingly engages a surface of the housing head during insertion of the end cap into the housing head to enforce a tilt angle at which the end cap is required to be presented to the housing head, the projecting portion being received in a recess formed in the housing head to remove the tilt angle on the rotation which brings the first conduit opening and the docking port into sealed communication. - View Dependent Claims (12, 13, 14)

15. A filter element for collecting material that is entrained in a fluid stream, the filter element having a tubular filter through which, in use, the fluid stream flows, and an end cap providing a flow conduit which extends between a first conduit opening and a second conduit opening communicating with the internal void of the tubular filter element, the axis of the first conduit opening being at an angle to the axis of the tubular filter;
-
the filter element being arranged for use with a housing for the filter element, the housing having inlet and outlet ports for the fluid stream, a housing bowl in which the tubular filter is located, and a housing head which provides at least one of the ports as a docking port for the first conduit opening, in use the end cap being inserted into the housing, and then rotated relative to the housing head about an axis perpendicular to the axis of the tubular filter and to the axis of the first conduit opening to bring the first conduit opening and the docking port into sealed communication; wherein the end cap has a cam device which acts on a surface of the housing head and is operable to apply a force urging the rotation which brings the first conduit opening and the docking port into sealed communication. - View Dependent Claims (16)
