The utility model relates to a car air compressor supercharger. The car air compressor supercharger comprises a control valve and a supercharger body, wherein an air inlet of the control valve is respectively connected with the feedback air pressure of a car air brake pipeline and an unloading valve, an air outlet is connected with the supercharger body, an air inlet of the air compressor supercharger body is respectively connected with an air filter and an engine air inlet pipe, and an air outlet is connected with an air compressor; an unloading valve with a pressure feedback device is arranged between the air compressor and an air storage barrel; by utilizing the car compressor supercharger, the air inlet efficiency of the air compressor can be maximally improved, and the supercharging air source of the air compressor can be cut off in time when the vehicle is in brake, so that the normal rotation of the air compressor can be guaranteed.
Description
Technical field
The utility model relates to a kind of vehicle air compressor blwr, and the method that improves air compressor air intake efficiency.
Technical background
The Main Function of vehicle air compressor is exactly for vehicle provides sufficiently stable pressurized air, along with motor vehicle braking system becomes increasingly complex, gas consumption is also increasing, and adding Pneumatic Suspension, pneumatic car door, Pneumatic seat etc., to be generalized to rapidly automobile first-class, and the automobile gas consumption all making rapidly increases, traditional Air compressor can't bear the heavy load, air compressor piston wearing and tearing aggravation, fault rate increases, and then injures again brake system, vehicle trouble rate is raise, and the people that can result in an automobile accident when serious dies.In order to address the above problem, present many driving engine producer adopts twin-tub Air compressor one after another, but twin-tub Air compressor is not only expensive, and oil consumption also increases thereupon.
Utility model content
For the deficiencies in the prior art, it is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, and can automatically adjust according to Air compressor no-load run, the different operating mode of load carrying the mode of operation of self device, thereby improve air compressor air intake efficiency, reduce compressor operation cost, improve the vehicle air compressor blwr in its service life.
For achieving the above object, the utility model adopts following technical scheme:
A vehicle air compressor blwr, comprises control cock and blwr body, and the admission port of described control cock connects respectively the feedback air pressure of automobile air brake pipeline and unloader valve, and air extractor duct connects the control end of blwr body; The admission port of described blwr body connects respectively airfilter and engine air inlet tube, and air extractor duct connects Air compressor; Between Air compressor and air tank, connect the unloader valve with press feedback device, when the air extractor duct of unloader valve has air pressure, air pressure feedback signal just can be delivered to control cock, and the outlet air pressure of unloader valve is while reaching the specified cut-off pressure of unloader valve, and air pressure feedback signal does not have air pressure.
Use the technical program can increase the intake efficiency of Air compressor greatly, and with low cost, easy to maintenance.Intake efficiency due to Air compressor is greatly improved in addition, so the speed of inflating of Air compressor is compared, traditional Air compressor is further promoted, thereby has further shortened the time of run of Air compressor, has improved its service life, has reduced oil consumption.
Accompanying drawing explanation:
Fig. 1 is the utility model vehicle air compressor blwr and each associated components connection diagram;
Fig. 2 is the structural representation of the utility model vehicle air compressor blwr.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, be the connection diagram of the utility model vehicle air compressor blwr and each parts.Comprise airfilter 01, engine air inlet tube 02, Air compressor 03, unloader valve 04 and air tank 05.The admission port of described Air compressor blwr 10 connects respectively air filter 01 and engine air inlet tube 02, and air extractor duct connects Air compressor 03.One unloader valve 04 with press feedback device is set between Air compressor 03 and air tank 05.At Air compressor blwr, control mouth simultaneously one control cock 20 is set, connect respectively the feedback air pressure signal 41 of brake piping 06 and press feedback device.
As shown in Figure 2, be the structural representation of the utility model vehicle air compressor blwr, wherein Air compressor blwr body comprises valve body 16, reversing piston 17, pull back spring 18, the initial position of reversing piston 17 is pressed in the bottom of valve body 16 by pull back spring 18.The control mouth of Air compressor blwr body is equipped with a control plunger 19, and control plunger 19 withstands on reversing piston 17.The admission port 11 of Air compressor blwr body connects airfilter 01, admission port 12 connecting engine air inlet pipes 02, and air extractor duct 13 connects Air compressor 03.Admission port 12 ends of connecting engine air inlet pipe increase by an atmospheric pressure compensating hole 15.
When Air compressor has just started bringing onto load work, Air compressor is got gas from airfilter, the air extractor duct pressure of unloader valve 04 starts to increase, feed back air pressure simultaneously and import control cock 20 into, and arrive the control chamber 16 of Air compressor blwr body, promoting control plunger 19 moves to right, thereby promoting reversing piston 17 moves to right together, close for 11 mouthfuls of Air compressor blwr body, open for 12 mouthfuls, now Air compressor starts to get gas from engine air inlet tube, is through turbo charged pressurization gas, so improved the intake efficiency of Air compressor because now enter the gas of Air compressor.Air pressure in air tank reaches after specified air pressure, Air compressor proceeds to no-load run, now unloader valve 04 starts pressure release, feed back air pressure disconnects simultaneously, the control plunger 19 of Air compressor blwr body 10 and reversing piston 17 are moved to the left simultaneously under the effect of pull back spring 18, close for 12 mouthfuls of Air compressor blwr body, open for 11 mouthfuls, now Air compressor is got gas from airfilter 01.The Income Air Status when improving Air compressor no-load run simultaneously, prevents the siphonage of Air compressor, at the admission port 12 of connecting engine air inlet pipe, has increased by a compensation orifice 15.
When vehicle need to be braked, the air pressure of brake piping enters control cock by 23 mouthfuls, act on control cock piston 26, promoting control cock piston 26 moves down, thereby 22 mouthfuls of closed control valve, gas in blwr body control chamber is by 24 mouthfuls of discharges of control cock, now the control plunger 19 of blwr body 10 and reversing piston 17 are moved to the left simultaneously under the effect of pull back spring 18, thereby 12 mouthfuls of closing connecting engine air inlet pipe, cut off the pressurization air source of Air compressor, to guarantee that under braking mode, each parts of driving engine can normally be worked.In addition, adopt this structure, even if brake system breaks down, the reversing piston of change-over valve is return normally, and Air compressor also can be got gas and normally work from airfilter, can not bring other problems.
