<p>In variable fill-type fluid couplings, a driving impeller and a driven runner are coupled for joint rotation by means of a liquid medium in an active liquid chamber formed by the rotating members. The active liquid chamber is continuously bled at a selected constant rate and continuously fed at a rate that can be changed to control the volume of fill of the liquid therein. Charging liquid is fed from a source to enter a mouth of the active liquid chamber. To insure that all of the charging liquid enters the active liquid collector the mouth is provided with a charging liquid collector that forces charging liquid past the mouth and into the active liquid chamber. The liquid collector can comprise an outer ring, an inner ring, and a plurality of pitched blades between the two rings. The collector rotates with the driving impeller, thereby forcing charging liquid past the mouth and into the active liquid chamber.</p> |
