PROBLEM TO BE SOLVED: To provide a fluid coupling for suppressing the lowering of an input capacity coefficient in other speed ratio regions than a low speed ratio region while sufficiently lowering the input capacity coefficient in the low speed ratio region. SOLUTION: The fluid coupling comprises an impeller 3, a turbine 4, a bearing 8, and a baffle 35. The impeller has an impeller shell 16, an impeller blade 17, and an impeller hub 18. The turbine is arranged opposite to the impeller in a fluid chamber, and it has a turbine shell 21 constituting a torus together with the impeller shell, a turbine blade 22, and a turbine hub 23. The bearing rotatably supports the impeller hub relative to the turbine hub. The baffle is provided in the torus for preventing part of the flow of operating fluid in the torus. The turbine shell has a hole 21a adjacent to the baffle so that the working fluid in the torus flows to the outside of the torus in a low speed ratio region. COPYRIGHT: (C)2005,JPO&NCIPI |
