ABSTRACT:
A viscous fluid type heat generator includes a housing assembly defining a heat generating chamber and a heat receiving chamber for permitting a heat exchanging fluid to circulate therethrough to receive heat from the heat generating chamber. A rotor element is supported by the housing assembly separately from the drive shaft to be rotationally driven by the drive shaft for rotation within the heat generating chamber. A viscous fluid is held in a gap defined between the inner wall surfaces of the heat generating chamber and the outer faces of the rotor element, for heat generation under a shearing stress applied by the rotation of the rotor element. Frictional coupling means are provided for frictionally coupling the drive shaft with the rotor element and for mechanically transmitting a rotation of the drive shaft to the rotor element to permit the rotor element to rotate in the heat generating chamber at a speed not higher than a predetermined thermal limit speed. If the rotation speed of the rotor element 22 exceeds the predetermined thermal limit speed, the viscous fluid could generate excessive heat, which would probably accelerate the thermal degradation of the viscous fluid.
