Description
The utility model relates to a kind of automobile-used air compressor super charge energy saving device, belongs to automobile-used air compressor technical field.
Originally, natural air is mostly adopted in the air inlet source of automobile-used air compressor, its off-load form generally is divided into two kinds of air inlet unloading type and exhaust unloading types, the air inlet unloading type is meant installs a pressure regulator valve in the automobile brake gas circuit, pressure regulator valve one end communicates with gas holder, the other end links to each other with pressure loosening valve (actuator) on being arranged on the air compressor cylinder cap, after gas holder reaches setting pressure, the pressure regulator valve conducting, make the pressure loosening valve action, back down the air compressor air intake valve block, air-inlet cavity is communicated with the piston head clearance, reach the purpose of off-load; The exhaust off-load then is that a unloading valve is set between air compressor and gas holder, the function of unloading valve is the pressure that it can sense gas holder, when its pressure reaches setting value, the bypass of unloading valve is opened, the relief opening of air compressor is communicated with atmosphere, and a side that communicates with gas holder is because the effect of one-way valve, and the pressurized air in the gas holder can not leak because of opening of unloading valve bypass, plays the purpose of off-load equally.But at present, because the raising of improving and braking ability being required of braking system, automobile-used air compressor is in order to reduce volume, to increase air displacement and adopt the mode of super charge, and the source of the gas of pressurized air is from the turbosupercharger of motor.After adopting super charge, corresponding air compressor and even the motor given all brings some disadvantages, start with from the off-load of air compressor below and analyze, if air compressor adopts the air inlet off-load, concerning air compressor, rising with intake temperature, the heat load of air compressor strengthens, sealing position reliability in its loose press mechanism reduces, after even more serious be the air inlet off-load, the last lubricating oil carry-over of air compressor is accumulated in the interior carbon deposit that forms of cylinder cap air-inlet cavity of air compressor easily, and carbon distribution has influenced the normal operation of air compressor and loose press mechanism thereof; Concerning motor, the machine oil of scurrying on the air compressor also enters into the intake duct of motor easily, influences the exhaust index of motor, and it is unallowable beyond doubt that this more and more is subjected to human today of paying attention in environmental protection.If air compressor adopts the exhaust off-load, concerning air compressor, heat load is same to be reduced seldom, but also its unique problem can appear, because super charge, and the straight-through atmosphere of relief opening might produce the phenomenon of suction pressure greater than exhaust pressure like this, make the air compressor exhaust valve plate especially reed valve plate have problems; Concerning motor, the pressurized air that during off-load engine supercharger is produced is discharged to atmosphere, and this is very uneconomic thing beyond doubt, and has influenced the performance of motor.
The purpose of this utility model provides a kind of automobile-used air compressor energy saving device of super charge, thereby overcomes the disadvantage that air compressor adopts super charge to bring.
The purpose of this utility model is achieved in that the unloading valve that a band pressure feedback signal interface is set between the relief opening of air compressor and gas holder, adorn an energy-conservation selector valve at the suction port place of air compressor, this selector valve is respectively by linking to each other behind super charge pipeline and natural inflow pipeline and the engine supercharger with before the pressurized machine, unloading valve not only has unloading function but also feedback function is arranged, and links to each other with energy-conservation selector valve by the pressure signal feedback pipe.The working principle of this device is that energy-conservation selector valve is in free state before the pressure of gas holder reaches setting value, and the air compressor air intake mouth communicates with the super charge pipeline by energy-conservation selector valve, and the gas that then enters air compressor is the higher pressurization gas of temperature; And after the pressure of gas holder reaches setting value, unloading valve begins off-load, simultaneously, feedback pressurized air flow to energy-conservation selector valve by the pressure signal feedback pipe, and energy-conservation selector valve is under the effect of pressurized gas, and its inner loose compression leg plug promotes the commutation plunger, the air compressor air intake mouth is communicated with the natural inflow pipeline, the gas that then enters air compressor is the relatively low natural air of temperature, and the pressurization gas that so neither can waste motor has reduced the heat load of air compressor again, reaches purpose of energy saving.
By adopting such scheme, when the air compressor off-load, because the effect of energy-conservation selector valve, the air inlet of air compressor is no longer entered by the super charge pipeline, and enter by the natural inflow pipeline, make the no longer pressurization gas of consumption of engine of the air that is discharged in the atmosphere, and the heat load of air compressor is minimized.Thereby solved automobile-used air compressor a large amount of waste pressurization gas and the too high disadvantage of air compressor heat load when adopting the exhaust off-load of super charge, reached energy-conservation purpose.
Below in conjunction with accompanying drawing the utility model is further specified.
