The cartridge 25 may be formed with annular ribs 25a. The spring 31 may be separate from or attached to the cover 19 or mounted on the cartridge to serve as a handle. The casing may be formed of two flanged sections 6, 14 connected by bolts 17, the lower section 6 being interchangeable with the casing of the filter described in U.S.A. Specification 2,081,968.
