Abstract
The utility model discloses a gas machine turbocharger by-pass valve assembly. The gas machine turbocharger by-pass valve assembly comprises a rivet, a rocker arm and a by-pass valve, wherein the rocker arm is connected on the top face of the by-pass valve through the rivet in a riveting mode, and rocker arm limiting protrusions are arranged on the top face of the by-pass valve. The gas machine turbocharger by-pass valve assembly is simple and reasonable in structure and convenient to install, due to the fact that the rocker arm limiting protrusions are arranged on the top face of the by-pass valve, the radial degree of freedom of the by-pass valve is limited, and the gas machine turbocharger by-pass valve assembly avoids abrasion caused by relative rotation of the by-pass valve and the rocker arm, and therefore avoids the situations that the abrasion causes faults such as untight closing, blocking and falling-off of the by-pass valve and finally affects performance of a turbocharger.
Description
Technical field
The utility model relates to engine art, particularly a kind of gas machine turbocharger bypass door assembly.
Background technique
Turbosupercharger because of its to improving engine power, reduce fuel consumption rate, improving the effect of discharging aspect, be widely used in the motor.Wherein the turbosupercharger purposes with exhaust gas by-pass valve is the most extensive, is used for diesel engine, petrol engine and gas machine in a large number.General turbosupercharger can't be taken into account low speed and high speed performance, and volute pressurized machine low-speed performance less than normal is good, but supercharger impeller exceeds the speed limit easily during high speed, so will fall a part of exhaust energy with the bypass valve bypass, reduces wheel speed and prevents hypervelocity.The vehicular engine major part all adopts band bypass valve pressurized machine at present.
Have the turbocharger bypass door assembly now as depicted in figs. 1 and 2, bypath valve 3 adopts stainless steels to be stamped to form, and rocking arm 2 adopts stamping forming blank to process, and both form by rivet 1 riveted joint again.Riveted joint back bypath valve 3 can rotate freely together with the mounting hole of rivet 1 with respect to rocking arm 2.Generally below rated engine speed, turbocharger bypass door major part is in closed condition to the applying working condition of diesel engine, and this moment, valve did not rotate, and this integral body of valve and rivet does not have relative movement with rocking arm, and the valve wearing and tearing are few; And the front-seat temperature in diesel engine whirlpool generally is no more than 680 ℃, so the applying working condition of bypath valve is not abominable, the wear-out failure of diesel pressure booster valve is also fewer on the market.
Yet for the gas machine, public transport gas machine particularly, in order to pursue low-speed big and low speed response performance, plateau applicable performance, general institute joins turbosupercharger and is partial to less volute pressurized machine, the engine speed of correspondence was lower when its bypath valve was opened, and public transport with the gas machine frequently start to walk, low speed quickens, so the most of operating mode of turbocharger bypass door all is in the frequent switching state of Open-closure.Temperature reaches as high as 760 ℃ before the gas machine whirlpool in addition, so the supercharger bypass valve door of gas machine is badly more many than the working environment of diesel engine.Therefore for the gas machine, when bypath valve 3 was opened, under the impact of hot air flow, bypath valve 3 can rotate freely together with the mounting hole of rivet 1 with respect to rocking arm 2, the general opening time of its bypath valve is long, Open-closure switches frequently, the front-seat temperature in whirlpool is higher, and the bypath valve wear-out failure is more.
The model utility content
The utility model is in order to overcome defective in the above-mentioned prior art, provide a kind of simple and reasonable, easy for installation, by the radially degrees of freedom of restriction bypath valve, prevent that bypath valve and rocking arm from relative rotation wearing and tearing, resistant to elevated temperatures gas machine turbocharger bypass door assembly taking place.
For achieving the above object, provide a kind of gas machine turbocharger bypass door assembly according to the utility model, comprising: rivet, rocking arm and bypath valve, rocking arm by rivet at the bypath valve end face; The bypath valve end face is provided with the rocking arm spacing preiection.
