Abstract
A fluid coupling comprising a pump having an annular pump shell with an annular core ring mounted on a pump hub and a plurality of impellers radially arranged in the pump shell, and a turbine arranged facing the pump and having an annular turbine shell with an annular core ring mounted on a turbine hub that can rotate relative to the pump hub and a plurality of runners radially arranged in the turbine shell, wherein the turbine shell is so constituted to slide on the turbine hub in the axial direction, and provision is made of a resilient urging means for pushing the turbine toward the side of the pump.
