Interior, and flowed out through exhaust passage.When exhaust passage stops suction, combustion gas control gas pressure inside is gradually risen, elasticity
Diaphragm gradually resets upwards, and rocker arm drives end, and also gradually upper lift resets under the mating reaction of reset spring, the closure end of rocker arm
It then gradually pushes and resets, seal plug also gradually blocks air inlet, until air inlet is blocked again, so according to exhaust
The negative inspiratory pressure situation cycle operation in channel.
Preferably, the conical degree of conical surface of the seal plug and the conical degree of conical surface of air inlet are different.
Preferably, the conical degree of conical surface of the seal plug and the conical degree of conical surface of air inlet are identical.
Preferably, it is additionally provided with spring between the seal plug and the closure end of rocker arm, for improving seal plug
Flexibility enables seal plug so as to coordinate and buffer the mismatch error formed between the swing of rocker arm and air inlet
It blocks on air inlet more flexiblely.
The utility model has the beneficial effects that: the utility model is by processing tapering and will be traditional for air inlet
It blocks valve block and is changed to the block head with taper, form adaptive closure using the taper of block head and the taper of air inlet and match
It closes, not only directly enhances the leakproofness of closure, but also the conical surface of air inlet can directly use formed punch punching press on air inlet
The mode of chamfering is process, high in machining efficiency, also directly reduces the difficulty of processing and processing cost of air inlet plugging structure.
