Abstract

The invention provides an intake and exhaust rotary valve of an internal combustion engine. The rotary valve comprises a valve cover, a valve body and a shaft, wherein the valve cover seals and coversthe valve body, a second through groove of the valve cover is matched with a first through groove of the valve body to form a shaft placing channel, the shaft is arranged in the shaft placing channelin a matched mode and can rotate, when the shaft rotates by a certain angle, two ends of an air inlet channel of the shaft are communicated with a second air inlet hole of the valve cover and a firstair inlet hole of the valve body in an aligned mode respectively, or two ends of an air outlet channel of the shaft are communicated with a second air outlet hole of the valve cover and a first air outlet hole of the valve body in an aligned mode respectively. The rotary valve is simple in structure and convenient to use, and air intake and air exhaust are conducted independently.

Description

technical field [0001] The invention relates to an intake and exhaust rotary valve of an internal combustion engine. Background technique [0002] Engines are used in many occasions, such as gearboxes of hybrid vehicles, etc., and internal combustion engines are a type of engine. They are all performed separately through a single intake valve and exhaust valve, so that multiple intake valves and exhaust valves are required, more parts are required, the structural arrangement is more complicated, and the overall internal combustion engine occupies a larger volume. Contents of the invention [0003] The invention aims to provide an internal combustion engine intake and exhaust rotary valve with simple structure, convenient use, and independent air intake and exhaust. [0004] The present invention realizes by following scheme: [0005] A rotary valve for intake and exhaust of an internal combustion engine, comprising a valve cover, a valve body and a shaft, the bottom of t...
