Abstract

A rotary fluid transmission between a pair of moving machine parts has frustoconical contact surfaces which are relatively rotatable and juxtaposed with one another and formed with openings or channels which communicate with one another. The contact between them can be direct or via sealing members for the openings or channels. The contact surfaces are provided so that they can axially separate at higher speeds and can contact each other at slower speeds or when the relative rotation terminates.
