Description of the drawings
Fig. 1 represents the structural representation of electromotor pressure relief pipe in embodiment of the present utility model.
Specific embodiment
Exemplary embodiment disclosed in this utility model is more fully described below with reference to accompanying drawings.Although showing in accompanying drawing
Exemplary embodiment disclosed in this utility model, it being understood, however, that may be realized in various forms the disclosure and should not be by
Embodiments set forth here is limited.On the contrary, there is provided these embodiments are able to be best understood from the disclosure, and energy
It is enough by the scope of the present disclosure it is complete convey to those skilled in the art.
In one embodiment of the present utility model, as shown in figure 1, electromotor pressure relief pipe includes:Pipeline body 1, pipe
Air venting valve 2 and gas safety valve 3 are installed on road body 1, and the first end of pipeline body 1 connects with engine air throttle
Connect, the second end of pipeline body 1 is connected by charge air cooler with supercharger;Wherein, the gas pressure in pipeline body 1 is more than one
During pressure preset, gas safety valve 3 carries out pressure release to the gas in pipeline body 1;Gas pressure in pipeline body 1 is little
When pressure preset, air venting valve 2 carries out pressure release to the gas in pipeline body 1.
In the present embodiment, by arranging gas on the pipeline body 1 of installation between supercharger and engine air throttle
Relief valve 2 and gas safety valve 3 so that driver closes immediately in release gas, i.e. engine air throttle suddenly, but increases
Depressor still keeps original state that runs up, when causing the gas pressure in pipeline body 1 to continue to increase, if pipeline body 1
Interior gas pressure is more than a pressure preset, can carry out pressure release to the gas in pipeline body 1 by gas safety valve 3,
It is enable to by gas safety valve 3 come the maximum of the gas pressure in control piper body 1, lets out so as to reduce gas
Pressure difference value at the air inlet of pressure valve 2 and gas outlet two ends.So, the gas pressure in pipeline body 1 is pre- less than the pressure
If value, when carrying out pressure release to the gas in pipeline body 1 by air venting valve 2 so that noise that pressure release is caused it is less or
Pressure release noise will not be produced, existing supercharging h type engine h is solved in closed throttle, larger disappointing noise is produced, from
And the problem of the NVH performances of reduction automobile, increased the NVH performances of automobile.
So, the present embodiment is let out by arranging gas on the pipeline body of installation between supercharger and engine air throttle
Pressure valve and gas safety valve, by gas safety valve come the maximum of the intrinsic gas pressure of control piper, reduce gas
Pressure difference value at relief valve air inlet and gas outlet two ends, so that passing through air venting valve to the intrinsic gas of pipeline
When body carries out pressure release, pressure release noise is less, solves existing supercharging h type engine h in closed throttle, produces larger letting out
Gas noise, so as to reduce the problem of the NVH performances of automobile, increased the NVH performances of automobile.
With continued reference to Fig. 1, in another embodiment of the present utility model, the first installing port is provided with pipeline body 1
11, the air inlet of air venting valve 2 is installed on the first installing port 11, gas outlet and the engine air air filter of air venting valve 2
Clear device is connected.So, the air inlet of air venting valve 2 can pass through the first installing port 11 and the gas phase in pipeline body 1
Connection, and because the gas outlet of air venting valve 2 is connected with engine air filter so that the gas in pipeline body 1
When body needs pressure release, the gas in pipeline body 1 can be circulated in engine air filter by air venting valve 2, from
And the gas in pipeline body 1 is recycled.
Additionally, specific, the second installing port 12 is provided with pipeline body 1, the air inlet of gas safety valve 3 is installed on the
On two installing ports 12, the gas outlet of gas safety valve 3 is connected with air.So, the air inlet of gas safety valve 3 can pass through
Second installing port 12 is connected with the gas in pipeline body 1, and because the outlet of gas safety valve 3 is connected with air,
So that when the gas in pipeline body 1 needs pressure release, the phenomenon of gas circulation blocking will not be produced so that pipeline body 1
Interior gas can be smoothly circulated in air by gas safety valve 3, be enable to be controlled by gas safety valve 3
The maximum of the gas pressure in pipeline body 1, has reached and has reduced the air inlet of air venting valve 2 and the pressure at the two ends of gas outlet
The effect of difference, so that when pressure release is carried out by air venting valve 2, will not produce pressure release noise, or letting out of producing
Pressure noise is less, increased the NVH performances of automobile.
Optionally, in addition, in another embodiment of the present utility model, the scope of the pipe thickness of pipeline body 1 is
1.8mm to 2.2mm.Specifically, the pipeline body 1 is duroplastss pipeline.So, the pipe thickness of pipeline body 1 is set to
1.8mm to 2.2mm, and material is duroplastss, and pipeline body 1 can be caused to bear the gas pressure in pipeline body 1
While, material-saving cost.
In another embodiment of the present utility model, a kind of electromotor is additionally provided, electromotor includes engine throttle
Door and any of the above-described embodiment in electromotor pressure relief pipe, wherein, the first end of the pipeline body of electromotor pressure relief pipe with
Engine air throttle connects.Specifically, the electromotor is engine with supercharger.
So, by connecting the electromotor pressure relief pipe on engine air throttle so that driver unclamps vapour suddenly
Car oil door, i.e. engine air throttle are closed immediately, but supercharger still keeps original state that runs up, and cause pipeline sheet internal
Gas pressure when continuing to increase, if the intrinsic gas pressure of pipeline is more than a pressure preset, gas safety can be passed through
Valve carries out pressure release to the intrinsic gas of pipeline, is enable to by gas safety valve come the intrinsic gas of control piper
The maximum of pressure, so as to reduce air venting valve air inlet and the pressure difference value at the two ends of gas outlet.So, in pipeline body
Interior gas pressure is less than the pressure preset, when carrying out pressure release to the intrinsic gas of pipeline by air venting valve so that
Noise that pressure release is caused is less or will not produce pressure release noise, solves existing supercharging h type engine h in closed throttle
When, larger disappointing noise is produced, so as to reduce the problem of the NVH performances of automobile, increased the NVH performances of automobile.
The above is preferred implementation of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of without departing from principle described in the utility model, some improvements and modifications can also be made, these improvement
Protection domain of the present utility model is also should be regarded as with retouching.
