Abstract
A fluid coupling has capacity coefficients in forward and reverse driving which can be arbitrarily selected to comply with demand for a wide variety of characteristics in accordance with the intended application. Pump blades Bp and/or turbine blades Bt are inclined in the direction of rotation of pump impeller P and a turbine runner T with inclination angles .theta..sub.2p and .theta..sub.2t with respect to normal lines Lp and Lt of the pump and turbine, respectively. Transfer of working fluid between the pump impeller P and the turbine runner T is thereby smoothened or suppressed in accordance with the inclination angles .theta..sub.2p and .theta..sub.2t, and thus the capacity coefficients in both forward and reverse driving can be arbitrarily selected and fixed.
