ABSTRACT:
A viscous fluid type heat generator including a housing assembly defining a heat generating chamber, a fluid storing chamber communicated through fluid passageway means with the 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 mounted on a drive shaft for rotation in the heat generating chamber with a gap defined between the inner wall surfaces of the heat generating chamber and the outer faces of the rotor element. The fluid passageway means includes a fluid withdrawing passageway for withdrawing the viscous fluid from the gap into the fluid storing chamber and a fluid supply passageway for supplying the viscous fluid from the fluid storing chamber into the gap. The fluid withdrawing passageway has a separate duct configuration and opens at one end to an outer peripheral region of the heat generating chamber to communicate the outer peripheral region with the fluid storing chamber. The fluid supply passageway has a separate duct configuration and opens at one end to a radially inner region of the heat generating chamber to communicate the radially inner region with the fluid storing chamber.
