To secure and control braking torque with a simple throttle valve 20 that does not need to withstand frequent opening and closing and high pressure due to the rotation of a crank shaft 12, in a braking torque generator using a compression/expansion engine.SOLUTION: In a process of compressing air taken in from an intake pipe 10e and discharging it from an exhaust port 10n, a compression/expansion engine obtains braking torque by compressing and expanding air. The compression/expansion engine controls the braking torque by adjusting the opening degree of a throttle valve 20 provided in the intake pipe 10n for taking in air.SELECTED DRAWING: Figure 1
【課題】圧縮・膨張機関を用いた制動トルク発生装置において、クランク軸12の回転に伴う頻繁な開閉や高圧に堪える必要のない簡素な絞り弁20で、制動トルクを確保し、制御すること。【解決手段】吸気管10eから吸入した空気を圧縮して排気口10nから排出する過程で、空気を圧縮および膨張させることで制動トルクを得る圧縮・膨張機関であって、空気を吸入する吸気管10nに設けた絞り弁20の開度を調整することで制動トルクを制御する。【選択図】図1
