Title:
FLUID COUPLING
Document Type and Number:
WIPO Patent Application WO/2005/064185
Kind Code:
A1
Abstract:
A fluid coupling having an impeller (3), a turbine (4), a bearing (8), and a baffle plate (35). The impeller has an impeller shell (16), impeller blades (17), and an impeller hub (18). The turbine is placed in a fluid chamber so as to face the impeller and has a turbine shell (21) constituting a torus together with the impeller shell (16), turbine blades (22), and a turbine hub (23). The bearing rotatably supports the impeller hub on the turbine hub. The baffle plate is provided in the torus and baffles a portion of a flow of an operation fluid flowing in the torus. A hole (21a) is provided in the turbine shell, close to the baffle plate. The hole (21a) allows the operation fluid in the torus to flow to outside the torus in a low speed ratio region.
