Abstract
A variable heat generating viscous fluid type heat generator having a housing assembly including movable and fixed plate members arranged to define an axially bounded region in which a heat generating chamber is formed to have an axial width which is changed by the axial movement of the movable plate member with respect to the fixed plate member within the housing assembly by the controlled operation of the moving unit. The change in the axial width of the heat generating chamber causes a change in the gap size of a fluid filled gap between the outer face of the rotor element and the inner wall surface of the heat generating chamber and, accordingly, the heat generating performance of the viscous fluid type heat generator is adjustably varied.
