Description
Technical field
The utility model relates to a kind of internal combustion engine air valve doors.
Background technique
Internal combustion engine is that a kind of important motivity of modern industrial society is mechanical, and air intake valve has as a kind of air intake apparatus
Important role, existing air intake valve design is not reasonable, and intake efficiency is relatively low, and is easy return-air, institute during the work time
With it is necessary to design the new product of one kind to meet actual use demand.
Utility model content
The utility model is directed to the deficiency of existing equipment, provides a kind of internal combustion engine bilateral air valve door, has good
Good using effect.
Internal combustion engine has the shell of Y shape with bilateral air valve door, and the shell is hollow, is provided in the tail end of shell
Overall channel, both ends are respectively arranged with channel one and channel two, and channel one and channel two are communicated with overall channel；At the middle part in channel one
It is fixedly installed unidirectional Air-regulating valves, the unidirectional outlet of Air-regulating valves.
The Air-regulating valves have supporting plate and flexible sheet, and venthole is provided on supporting plate, living in the top of venthole
It is dynamic to be covered with flexible sheet；Air-flow is to when flowing, flexible sheet is upwarped, and air-flow passes through vent flow above flexible sheet；Gas
When flowing to be flowed downward above flexible sheet, flexible sheet tightly pushes down supporting plate, and air-flow is prevented to flow.
The number of air hole is not limited to one, preferably honeycomb venthole.
The flexible sheet is sheet rubber.
The middle part in channel one is provided with the expansion arc of taper or spherical shape, Air-regulating valves, channel one are provided in expansion arc
It is made of upper pipeline and lower pipeline, upper pipeline and lower pipeline are welded on one by ultrasonic plastic welder at the middle part of expansion arc
It rises, plays connection and shell sealing function.
The overall channel outer rim is provided with rubber seal, is sealed when for being assemblied on internal combustion engine.
It is respectively arranged with mounting hole in the two sides of overall channel outer rim, for being fixedly mounted on internal combustion engine.
In channel one and/or channel, the middle part or top of two outer walls are additionally provided with buckle boss, are installed for facilitating.
When in use, when internal combustion engine is in exhaust condition with bilateral air valve door, gas can pass through one He of channel
Channel two is exhausted outward simultaneously, and exhaust efficiency is high；In air inlet, due to being provided with unidirectional tune at the middle part in channel one
Air valve, one not air inlet of channel, two air inlet of channel can prevent gas from flowing into excessive, reduce the air-fuel ratio in internal combustion engine, guarantee
Fuel oil obtains abundant and reasonable burning, reduces the discharge of oxynitrides.
The utility model structure is simple, easy to use, has good use and promotion effect.
Detailed description of the invention
Below in conjunction with attached drawing, the utility model is described in further detail
Fig. 1 is schematic cross-sectional view of the utility model internal combustion engine bilateral air valve door in exhaust condition.
Fig. 2 is schematic cross-sectional view of the utility model internal combustion engine bilateral air valve door in air-suction state.
Fig. 3 is the structural schematic diagram of the utility model internal combustion engine bilateral air valve door.
