Abstract

The invention provides a coaxial connecting device for a rotating body and a valve, and belongs to the technical field of mechanism design. The device comprises an air compressor, an engine, a turbine, a connecting pipe, a rotating shaft, a volume cavity, a fixing body, a through pipe, a separating plate, a rotating body and a connecting plate; one end of the rotating body extends into the first through pipe and is in sealing contact with the wall surface of the first through pipe, and while the other end of the rotating body is integrally fixedly connected with the separating plate; two ends of the first connecting pipe are respectively communicated with an air inlet pipe of the air compressor and an exhaust pipe of the turbine; in case of relatively high pressure difference between the previous period and the later period of the turbine, the rotating body drives a valve to clockwise rotate, the exhaust of the engine is high in recycling efficiency, and the detonation pressure of the engine is relatively low. The device is reasonable in design, simple in structure, and suitable for an exhaust gas recycling system of a supercharged engine.

Description

technical field

[0001] The invention relates to an exhaust gas recirculation system in the technical field of mechanical design, in particular to a coaxial connection device between a rotating body and a valve. Background technique

[0002] Harmful emissions from engines are a major source of air pollution. With the increasing importance of environmental protection, the goal of reducing harmful emissions from engines has become an important direction for engine development in the world today. With the world's consumption of petroleum products increasing year by year, international oil prices remain high, and the economy of diesel vehicles is becoming more and more prominent, which makes diesel engines occupy an increasingly important position in vehicle power. Therefore, it is the primary task of diesel engine designers to carry out research on the control methods of harmful emissions from diesel engines. Exhaust gas recirculation system is to send a small part of the exhau...
