HEAT GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a vehicular heat generator capable of smoothly transferring viscous fluid in the rotor end area to another area through a communicating passage provided in the rotor interior. SOLUTION: The end surface 21a of a cylindrical rotor 20 has a port opened for a communicating passage 26 formed inside the rotor to guide viscous fluid existing in a ring-shaped recess 25 (the rotor end area) to another area. The rotor end surface 21a is provided with collecting grooves 27 and collecting walls 28 connected to the communicating passages 26 and extending in the anti-radius direction of the rotor 20. When the rotor 20 rotates in the arrow A1 direction, the collecting grooves and the walls 27, 28 not only acquire and collect viscous fluid in the ring-shaped recess 25 and guide it to the communicating passage 26 ports but also give force feeding force to the viscous fluid collected in the guiding process and forcibly send viscous fluid into the communicating passage 26 with the force.
