Abstract:
A filter for filtering a flowing substance, the filter comprising a casing having a cylindrical wall surrounding a central axis, said casing including an open first end and a second end opposite the first end, a substantially cylindrical, replaceable filter means fitted coaxially surrounding the central axis and positioned inside the casing, a flow to be filtered being arranged to pass through the filter means, and a collar coaxially surrounding the central axis and positioned at the first end of the casing for connecting the casing to a device assembly including inlet and outlet ducts for the flow to be filtered, the filter including a support member coincisent with the central axis which is distinct from the casing and extends axially from the collar, the support member being formed of an axial spindle having first and second opposite ends and being positioned within the filter means, a connection for connecting the first end of the spindle to the collar, an end flange at the second end of the spindle opposite to first end of the spindle, said end flange being a separate component from the casing and including a cylindrical outermost surface that is surrounded by and in fixed, radially-sealed engagement with an inner cylindrical surface of the cylindrical wall of the casing to prevent the end flange from moving axially toward the first end of the casing, whereby the radial surface of the end flange will receive a force caused by a positive interior pressure in the casing directed axially towards the second end of the casing.
