EXHAUST GAS RECIRCULATION DEVICE

摘要

mechanical engineering; internal combustion engines. SUBSTANCE: device has inlet and outlet pipelines communicating through recirculation channel, and shutoff member. According to invention, inlet pipeline is provided in section at place of pipeline-to-recirculation channel connection with technological projections made inside and shutoff member installed inside between projections. Projections are located before and after place of connection of inlet pipeline and recirculation channel in direction of air flow. Shutoff member is bushing installed with clearance for overlapping recirculation channel at displacement between projections under action of gravity force and air pressure differential in inlet pipeline. EFFECT: increased accuracy of metering out bypassed gases, improved reliability of device and reduced labour input for servicing. 1 dwg
