トンエンジンの冷却装置。While oil is supplied to the hollow part inside the rotor to cool the rotor, an annular groove is formed in at least one of the rotor journal part of the eccentric shaft or the bearing metal part of the rotor, and the oil is forced into the annular groove to cool the rotor. In a rotary piston engine, one end opens into the annular groove and the other end opens into a hollow portion located behind the trailing side cut-up portion of the rotary recess. A cooling device for a rotary piston engine, characterized in that a communication path for supplying oil intensively is provided behind an upward portion.
