Abstract
The utility model discloses a connecting structure for an air filter and a supercharger. The connecting structure for the air filter and the supercharger comprises the air filter, the supercharger and an air inlet connecting pipe which connects the air filter and the supercharger; an air compressor air obtaining opening which is communicated with the air compressor is formed in the air inlet connecting pipe; an oil-gas separator air inlet connecting opening which is communicated with an oil-gas separator is formed in the air inlet connecting pipe; the air compressor air obtaining opening is formed outside an angle at an air inlet end of the air inlet connecting pipe and accordingly smoothness of air obtaining of the air compressor is guaranteed and the air compressor is avoided from oil spoiling; the air inlet connecting opening of the oil-gas separator is formed outside the angle at an air outlet end of the air inlet connecting pipe and accordingly the separating effect of the oil-gas separator and the engine oil consumption of an engine are effectively avoided from being influenced due to the fact that separation gases are sucked into the air inlet connecting pipe when the gas pressure is low.
Description
Technical field
The utility model relates to the linkage structure of a kind of air filter and pressurized machine.
Background technique
The gas of discharging in crankcase can flow directly in atmosphere and go, and also can import engine supercharger gas compressor.The suction tude that the gas of discharging in crankcase is imported to motor is conducive to improve motor emission performance.Current closed crankcase ventilates deaerator intake interface is set on air inlet tube, air compressor is got gas air compressor air hatch is set on air inlet tube, the draught head of the less consideration air inlet tube of interface arrangement form and deaerator steam outlet pipe, air inlet tube and air compressor, owing to being negative pressure in air inlet tube before pressurized machine, cause mixed gas in deaerator to be entered pressurized machine by suck-back.Interface arrangement form is generally perpendicular to the airflow direction of air inlet tube, and air compressor is got gas and do not taken into full account the pressure change of air inlet tube in corner, causes air compressor to get gas not smooth, and air compressor is altered oil.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned defect, provide a kind of ensure air compressor get gas smooth and easy, avoid air compressor to alter oily phenomenon and can avoid in bridge piece sucking when gas pressure is lower the air filter of divided gas flow phenomenon and the linkage structure of pressurized machine.
In order to solve the problems of the technologies described above, the utility model comprises the air inlet tube of air filter, pressurized machine and connection air filter and pressurized machine, described air inlet tube is provided with the air compressor air hatch being communicated with air compressor, on described air inlet tube, be also provided with the deaerator intake interface of connecting with deaerator, its structural feature is that described air compressor air hatch is arranged on air inlet tube inlet end bent angle outside, and described deaerator intake interface is arranged on bent angle outside, air inlet tube outlet side.
Described air inlet tube comprise flat segments, under the section of stretching and lower flat segments, upper flat segments and under be arc transition between the section of stretching, air compressor air hatch is arranged on the outside of arc transition place, air inlet tube; Under be arc transition between the section of stretching and lower flat segments, deaerator intake interface is arranged on the outside of arc transition place, air inlet tube.
Described air compressor air hatch and under angle between the section of stretching be less than 90 °.
Angle between described deaerator intake interface and lower flat segments is less than 90 °.
Compared with prior art the utlity model has following advantage: air compressor air hatch is arranged on air inlet tube inlet end bent angle outside, because gas flow rate outside bent angle is slow, air pressure is higher, ensure that air compressor gets the smoothness of gas, avoided air compressor to alter oily phenomenon; Deaerator intake interface is arranged on bent angle outside, suction tude outlet side, outside bent angle, gas flow rate is slow, pressure is higher, while effectively having avoided the interior gas pressure of air inlet tube lower, suck divided gas flow, affect the engine oil consumption of deaerator separating effect and motor.
Brief description of the drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, this air filter comprises air filter 1, pressurized machine 3 and is connected air filter 1 and the air inlet tube 2 of pressurized machine 3 with the linkage structure of pressurized machine, air inlet tube 2 is provided with the air compressor air hatch 4 being communicated with air compressor 6, on air inlet tube 2, be also provided with the deaerator intake interface 5 of connecting with deaerator 7, air compressor air hatch 4 is arranged on air inlet tube 2 inlet end bent angle outsides, and described deaerator intake interface 5 is arranged on air inlet tube 2 bent angle outsides, outlet side.
As shown in the figure air inlet tube 2 comprise flat segments, under the section of stretching and lower flat segments, upper flat segments and under be arc transition between the section of stretching, air compressor air hatch 4 is arranged on the outside of arc transition place, air inlet tube 2; Under be arc transition between the section of stretching and lower flat segments, deaerator intake interface 5 is arranged on the outside of arc transition place, air inlet tube 2.In the present embodiment air compressor air hatch 4 and under angle between the section of stretching be less than 90 °.Angle between deaerator intake interface 5 and lower flat segments is less than 90 °.
Gas flow after air filter 1 is filtered is during through air inlet tube 2, and in corner flow velocity and the larger variation of pressure generation, gas flow rate is very fast inside bent angle, and air pressure is lower, and outside gas flow rate is slower, and air pressure is higher.Air compressor air hatch 4 is arranged at air inlet tube 2 inlet end bent angle outsides, makes full use of the high pressure in bent angle outside, makes air compressor get gas and becomes more smooth and easy, meanwhile, has avoided air compressor 6 to alter oily problem.
Closed crankcase ventilates need to import to engine air inlet tube 2 by the gas after deaerator 7 separates, air inlet tube 2 is provided with deaerator intake interface 5, and the gas after deaerator separates enters suction tude with fresh air after air inlet tube 2 mixes after pressurized machine 3.Deaerator intake interface 5 is positioned at air inlet tube 2 bent angle outsides, outlet side, and bent angle outside pressure is higher, while effectively having avoided the interior gas pressure of air inlet tube 2 lower, sucks divided gas flow, affects the engine oil consumption of deaerator separating effect and motor.
The utility model is not limited to above-mentioned embodiment, and those skilled in the art, not departing under the prerequisite of spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
