Japanese Patent JPS5240710
Kind Code:
B2
Abstract:
The present invention provides a fluid coupling containing a working fluid and comprising a rotatable driving member, at least part of which is mounted for co-axial rotation within a working chamber forming part of a rotatable driven member. Shear spaces are defined by opposing faces of said driving member and working chamber and a reservoir forms part of the driven member. One or more inlet ports are provided adjacent the periphery of the driven member and connecting the working chamber with the reservoir and one or more outlet ports are located radially inwardly of the inlet port or ports. A fluid transfer duct means extends axially between the outlet port or ports and one or more flow accelerating passages within that part of the driving member located within the working chamber. Each fluid flow accelerating passage is open at each end and extends from a location immediately radially outwardly of the outlet port or ports to the periphery of the driving member. The periphery of the driving member is located at a greater radial distance from the co-axial centres of the driving and driven members than the inlet port, and a valve member is movable to open or close the outlet port or ports and control the flow of fluid from the reservoir to the shear spaces via the said transfer duct and fluid flow accelerating passages.
