    • A viscous fluid type heat generator having a heat generating chamber in which viscous fluid is confined to frictionally generate heat by an application of shearing action due to rotation of a rotor element (15) rotated by a drive shaft (14), a heat receiving chamber (9) arranged adjacent to the heat generating chamber (8) to permit heat exchanging liquid to receive heat from the viscous fluid within the heat generating chamber (8) during flowing through the heat receiving chamber (9), partitioning walls (5,6) arranged in the heat receiving chamber (8) to define a plurality of radially inner and outer concentric annular liquid passages between a liquid inlet (10) for entrance of the heat exchanging liquid and a liquid outlet (11) for delivery of the heat exchanging liquid, and a liquid guide (42) arranged in a position adjacent to the liquid inlet (10) to divert a part of the heat exchanging liquid entering the heat receiving chamber (9) toward the radially outermost liquid passage in the heat receiving chamber (9).

    • A viscous fluid type heat generator including a housing assembly defining a heat generating chamber and an additional chamber communicated through fluid passageway means with the heat generating chamber, these chambers forming a fluid-tight chamber for accommodating a viscous fluid, 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 together therewith 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 additional chamber and a fluid supply passageway for supplying the viscous fluid from the additional chamber into the gap. The fluid withdrawing passageway includes a withdrawing channel formed along one of the inner wall surfaces of the heat generating chamber. The withdrawing channel extends up to and opens to an outer peripheral region of the heat generating chamber to communicate the outer peripheral region with the additional chamber.
