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 device for coaxially connecting a rotating body and a valve. Background technique [0002] Engine harmful emissions are a major source of air pollution. With the increasing importance of environmental protection issues, the goal of reducing harmful emissions from engines has become an important direction for engine development in the world today. With the consumption of petroleum products in the world rising year by year, international oil prices remain high, and the economy of diesel vehicles has become increasingly prominent, which makes diesel engines occupy an increasingly important position in vehicle power. Therefore, it is the first task for the designers of diesel engines to carry out research on the control methods of harmful emissions from diesel engines. The exhaust gas recirculation system returns a small part of the exha...
