The strainer has first and second perforated conical sheet metal walls with an outer wall tapering from the inlet toward the outlet and an inner wall tapering from the outlet back to an apex at the inlet. The strainer is positioned by an annular bead at the inlet sealing against the body at the inlet and fitted within an annular groove formed in both the body and the cover. The strainer is supported at the outlet by a number of radially extending projections which engage the strainer at the point where the inner and outer walls are joined together.
