ABSTRACT:
A temperature and speed responsive control for a fluid coupling adapted to drive a cooling fan for an internal combustion engine. The coupling is of the hydrokinetic type and includes an input or drive member adapted to be driven by the engine, an output or driven member defining a housing adapted to carry the fan, a fluid working chamber defined by the drive and driven member, a cylindrical sleeve controlled by a fluid pressure and operative to vary the output speed by controlling fluid circulation in the working chamber, means in the working chamber for producing the fluid pressure, and temperature and speed responsive means for controlling the fluid pressure to the sleeve in response to temperature and speed changes.
