ABSTRACT:
A rotational speed differential type torque transmitting assembly includes a rotor rotatably disposed in a drive housing. During rotational speed differential between the rotor and drive housing, hydraulic fluid is discharged out of variable volume chamber on discharge stroke of the associated piston. Orifices are provided to restrict flow of hydraulic fluid discharged, inducing a pressure rise and adiabatic compression of the hydraulic fluid, causing heat build-up in the rotor. In order to prevent excessive rise in temperature of the assembly, a temperature responsive type spool valve is provided to close the orifice means in response to temperature rise of the hydraulic fluid in the rotor.
