Abstract
The invention provides a rotary air intake and exhaust connecting mechanism in the technical field of mechanical design. The connecting mechanism comprises a compressor, an engine, a turbine, a connecting pipe, an adjusting mechanism, a rotating body, a through tube, a stepping motor and a rotating shaft, wherein the air inlet and the air outlet of the engine are respectively connected with the air outlet of an engine air inlet pipe and the air inlet of an engine exhaust pipe; the rotating body is arranged in the adjusting mechanism; the through tube is arranged on the rotating body; one end of the rotating shaft is connected with the stepping motor; the other end of the rotating shaft passes through the lower wall surface of the adjusting mechanism to be fixed together with the rotating body. When the engine is under the low-speed working condition, the stepping motor drives the rotating body to rotate so as to enable a first connecting pipe and a second connecting pipe to be communicated, therefore, the surge of the compressor can be avoided; when the engine is under the high-speed working condition, the stepping motor drives the rotating body to rotate so as to enable a third connecting pipe and a fourth connecting pipe to be communicated, therefore, the detonation pressure of the engine is relatively low. The connecting mechanism is reasonable in design, simple in structure and suitable for the design of air intake and exhaust systems of supercharged engines.
