<p>A scoop controlled fluid coupling has a toroidal working circuit (W) defined by vaned impeller and runner elements (11,12). Working liquid is supplied to the working circuit (W) from a rotating reservoir (9) by an adjustable scoop tube (15) having a scooping orifice (16), the radial position of which is to determine the degree of filling of the circuit (W). To counteract unintentional changes in the filling due to thermal expansion of the liquid, the runner diameter is about 10% smaller than that of the impeller, and the runner has a varying-size core structure (52) and two sets of holes (54,55).</p> |
