Adjacent discs of the disc assembly engage each other and each disc has a surface configuration that cooperates with the surface configuration of the next adjacent disc to define a plurality of concentric passages between the discs. A plurality of elongate rigid rods secure the disc through yieldable joints to a pair of circular end support members and to circular intermediate support members.
