Below mainly to the gas feeder in the air feed spare: with use device of air in pneumoelectric magnet valve, gas valve, ram air valve, shunt valve and the executive item: starting device, pressurized air air inlet boosting device describe respectively outward to draw the servo-unit pneumatic engine.

Bump valve with pneumoelectric and be installed on each gas dome of high-pressure gas container, and be connected, by the switching manipulation control of cooresponding compression indicator below on the pressure dial plate in the operator's compartment with the gas total pipeline.Its general structure is: a valve body, be processed with the valve spring chamber in the valve body, in be equipped with magnet coil, valve, valve pull back spring, once opening the corresponding solenoid valve switch, make magnet coil galvanization generation magnetic attraction valve in the valve body, high compression air in the compression valve pull back spring, gas dome is just outwards carried use through the valve port place; Once turning off the corresponding solenoid valve switch, electromagnetic coil circuit disconnects in the corresponding valve body, and magnetic force disappears, valve return rapidly under the tension force effect of pull back spring, and valve also closes valve port, the gas dome inner high voltage air that contracts can not outwards be carried, and guarantee no leak.

Gas valve is installed on the vehicle frame, and the place is installed into gas-tpe fitting at admission port, and is connected with the gas total pipeline, both can be connected as a single entity with ram air valve or shunt valve, also can communicate by pipeline, by the control of the gas transmission pedal operation in operator's compartment displacement.Its general structure is: a valve body that is fixed on the vehicle frame, and valve body lower portion is processed with the valve box, can assemble valve, valve pull back spring and bottom end cover, and bottom end cover links to each other solid with valve body by screw; Be processed with induction opening on valve body lower portion or bottom end cover, the admission port place can be installed into gas-tpe fitting, uses feed channel to install, and makes pressurized air enter the valve box; Valve body middle part is processed with valve seat and valve port, the valve valve seat sealing valve port of can conflicting; Tappet, tappet pull back spring can be assembled in valve body top, and adapt to corresponding tappet and slide up and down within it, also are processed with the duct of giving vent to anger and are connected with the air inlet duct of ram air valve (or shunt valve); Tappet lower end conflict valve, top conflict torque arm roller, its top also should be assembled and be prevented the seal ring that leaks gas; Roller props up a end in torque arm, conflict tappet top by removable pin; Torque arm on valve body, and is equipped with spacing trimming screw by positioning support, by adjusting, can adjust the gas transmission free pedal; The other end of torque arm links to each other with gas transmission pedal drive part by removable pin, as long as just trample the gas transmission pedal and can be linked.When stepping on the gas transmission pedal, one end of torque arm just is pulled, roller just can press down tappet, valve just can very be left in the tappet lower end, stroke by control gas transmission pedal, the valve opening of control gas valve is controlled displacement, when unclamping the gas transmission pedal, pedal is self-return under its pull back spring tension, the suffered pulling force of torque arm disappears, and the suffered roller pressure in tappet upper end disappears self-return under its pull back spring tension force effect in succession, the suffered tappet pressure of valve tip disappears, also also self-return under its pull back spring tension force effect, thereby close port, the gas transmission air-flow interrupts fully.The gas transmission pedal is installed in Das Gaspedal the right in the operator's compartment, and arranged side by side with Das Gaspedal, two pedals can be collectively referred to as acceleration pedal, divides to be called major and minor acceleration pedal, and the ground row is two steps on or singly step on to their for the right crus of diaphragm by chaufeur.The gas transmission pedal is the same with Das Gaspedal, and (preceding) end props up on the operator's compartment base plate with the location backing pin thereafter, and can be that rotating shaft is free movable with the backing pin, thus the interlock drive link.

On some full-sized car, bigger with the needed air demand of mechanism of qi structure, when depending the tolerance possibility deficiency of gas valve conveying alone, can assemble ram air valve, otherwise not need.Ram air valve also should be installed on the vehicle frame, and itself and gas valve, shunt valve can be connected as a single entity, and also are connected by pipeline, can be divided into leather cup formula ram air valve and piston type ram air valve according to version.The ram air valve structure of two kinds of forms is similar substantially, their general structure is: a valve body that is fixed on the vehicle frame, be processed with the valve box in the bottom of valve body, can assemble valve, valve pull back spring, plug screw, be processed with induction opening on the plug screw, the admission port place is equipped with the air inlet pipe joint and is connected with the gas main pipe rail; The middle part is processed with valve seat, valve port, increases air flue, the tappet jack; Leather cup or piston and spring, tappet, loam cake etc. can be assembled in top, valve body and loam cake connect envelope by screw, and constitute leather cup or the plunger backer leather cup or the pistons work chamber of air pressure by compression, the upper end of tappet links to each other with leather cup or piston, sharp conflict valve tip awl nest is bored in the lower end, part is answered the fitting tight circle in the valve body trepanning, and leather cup or piston spring chamber should be processed with the duct that communicates with atmosphere.The ram air valve of two kinds of forms just promotes the part difference of tappet, and promptly a kind of is leather cup, and a kind of is piston.When being leather cup formula ram air valve, the upper end of tappet links to each other solid with leather cup by nut and two circular intermediate plates, and the tappet length below the leather cup can suitably be adjusted; Spring below the leather cup is a turriform spring, and it can order about leather cup and restore, and leather cup week is along being pressed between valve body and the loam cake by trim ring.When being the piston type ram air valve, the upper end of tappet inserts in the trepanning of piston lower end, and tappet length also can suitably be adjusted; Piston spring is a cylinder spring, can order about piston and set back; Answer the fitting tight circle between all discs of piston and the valve body inner headed face.The principle of work of ram air valve is: the backside space of at first filling leather cup or piston from the pressurized air of gas valve conveying, export from air extractor duct then, displacement increase along with gas valve, the suffered pressure of leather cup or piston also increases thereupon, when pressure increase to can overcome each spring close tension force the time, the ram air valve door just is opened, pressurized air with the gas main pipe rail, just can enter the valve box from another admission port, enter through valve port again and increase air flue, tunnel and gas transmission stream converge, and from air extractor duct output, use the gas consumption of gas executive item to obtain increasing; Along with the displacement continuation increase of gas valve, the ram air valve valve opening also increases thereupon, increases corresponding the obtaining of tolerance and increases, and when the gas transmission of gas valve advances to increase to maxim, increases tolerance and also should reach maxim; When the displacement of gas valve reduced, the suffered pressure in the leather cup or the piston back side is little to be reduced thereupon, and spring tension makes leather cup or piston, tappet, valve recover respective distance respectively, thereby valve opening is reduced, and increases tolerance and reduces thereupon; When the displacement of gas valve is reduced to certain value, ram air valve door contract fully, increasing tolerance is zero, increases gas and stops.In a word, the tolerance that increases of ram air valve is by the control of the displacement of gas valve, that is: within the specific limits, the tolerance that increases of ram air valve increases with the displacement of gas valve, reduces and reduces, and when displacement was reduced to a certain degree, it was zero increasing tolerance.

Shunt valve is the device that separates independent gas supply with the gas executive item to each, generally by two or more electromagnetic valves structure body that is connected as a single entity, whole valve body also is installed on the vehicle frame, itself and gas valve or ram air valve both can be connected as a single entity, also can be connected by pipeline, be connected by shunt tubes with the cushion gas executive item, the number of electromagnetic valve is by the number decision of first order usefulness gas executive item, for example, first order usefulness gas executive item has the traction servo-unit, pneumatic starting device, during three of air pressure tipping devices, then electromagnetic valve just should have three in the shunt valve, if deduct the air pressure tipping device, then electromagnetic valve just only needs two in the shunt valve.Shunt valve is controlled by branch switch, branch switch generally is installed on the operator's compartment pressure dial plate, selects the different application approach that requires during according to the use high pressure gas for use by the chaufeur simple operations, make the device gas circuit of corresponding requirements work open-minded, and do not require the gas circuit sealing of work; When not using high pressure gas, each all is closed with the gas gas circuit, leaks further to prevent high pressure gas.

The traction servo-unit is generally a kind of high pressure gas rotation acting parts of eddy current vane type, whole servo-unit is installed in change-speed box rear end (also can design at other low speed transmission position), mainly, be communicated with by pipeline with shunt valve by formations such as the servo-unit axle of inside and outside eddy current shell (abbreviation inside and outside shell) that forms eddy current and transmission compressed-air power and impellers.Shell is fixed on the transmission case rear end by interior six (or four) square toes screw, six (four) must bury sunken in the screw, with the anti-friction impeller that bumps, inside and outside eddy current shell is by the boss and the shoulder at its middle part, the end edge and the annular groove of its front portion, the disk of its rear end merges sealing with end along inlaying mutually, and connect solid by screw in the rear end, form three Room: the intake swirl chamber, the impeller whirl chamber, the exhaust whirl chamber (is called for short inlet plenum, blade wheel chamber, exhaust chamber), inlet plenum is the space that forms intake swirl, constitute by inner casing boss forward outer surface and shell shoulder front interior, communicate with shunt valve by air inlet pipe, communicate with impeller wheel chamber by the intake swirl hole again; Blade wheel chamber is the space of impeller rotation, is made of inner casing inner face and shell front end bottom surface, and by intake swirl hole air feed, the pressurized air after the acting is arranged from exhaust eddy current hole to exhaust chamber; Exhaust chamber is the space that forms the exhaust eddy current, is made of inner casing boss external rear face and shell shoulder rear portion inner face, is connected with blade wheel chamber by exhaust eddy current hole, communicates with freeing pipe by deflation hole again; Port processing is on shell, all corresponding pipeline is installed by adaptor union, be connected with corresponding parts, promptly induction opening is connected with shunt valve, and deflation hole is connected with pressurized air secondary use device (as: diesel motor pressurized air air inlet boosting device, cooling control apparatus).The air-flow line of centers of port should be the tangent line of inlet and outlet chamber center circle anchor ring respectively, and guarantees that air flow line complies with the impeller hand of rotation; Intake and exhaust eddy current hole processing on inner casing, numbers such as one-tenths, even, be staggered, their line of centers all must be in the blade wheel chamber near the tangent line of impeller outer along certain center circle cylinder, and guarantee that air flow line complies with the impeller hand of rotation; The hand of rotation of impeller is meant the rotation direction of impeller when automobile advances; Each air chamber and duct inwall require smooth, to reduce the useless consumption of air pressure energy as far as possible, add and also must accomplish that inlet plenum volume ratio exhaust chamber volume is little, induction opening is littler than deflation hole, intake swirl boring ratio exhaust eddy current hole is little man-hour, some should also will guarantee good sealing property in the leak free place.The servo-unit axle is exactly the axis body that the transmission shaft rear end is prolonged, and is processed with male splines on the axis body, is convenient to install impeller; Impeller is installed in the blade wheel chamber, constitute one by hub splines, two ends plush copper, blade, front apron, the hub splines endoporus is processed with and the servo-unit axle male splines female splines of fit mutually, axle sleeve two ends plush copper is so that conflict bearing inner ring and spacer ring, when mounted, make bearing, impeller, bead etc. can both compress the location mutually, prevent end float misalignment; Axle sleeve is processed with some well-distributeds watt shape blade outward, and each blade all tilts with same direction (backset eddy direction), and is connected as a single entity by front apron, and lobe numbers should be more than two times of intake swirl Confucius number; Wipe under the prerequisite bump not producing, blade and blade wheel chamber inwall gap must reduce as far as possible.This blade wheel structure helps making full use of the air pressure energy, and the high pressure gas after the acting is in time discharged, and helps again when not using servo-unit, reduces the impeller rotational resistance, prevents to influence driving efficiency.Center, inner casing rear end is processed with bearing saddle bore, so that ball bearing of main shaft supporting servo-unit axle to be installed, the former part (as: centre brake base, car speed mileage table transmission worm gear, worm screw, spiral case, connecting flange, jam nut etc.) of change-speed box rear end that is contained in is all in being installed on the servo-unit rear end by former mode.When automobile need carry out auxiliary traction, high pressure gas enters induction opening from shunt valve by the power-assisted subtube and enters inlet plenum, and form elementary belt eddy current, the eddy current gas of inlet plenum enters blade wheel chamber from each intake swirl hole again, form strong eddy current and promote impeller and do, eddy current gas after acting in-line arrangement gas eddy discharge orifice again enters exhaust chamber formation exhaust eddy current, enters high pressure gas secondary use device along freeing pipe then.Because the pressurized air of discharging also has certain pressure and impulsive force, and has a heat absorption function, should manage it is advanced secondary utilization (as use diesel motor is carried out plenum or the adjusting work of lowering the temperature), make energy reduce loss, and improve the engine operation situation, reduce exhaust noise and pollution etc.

The outer starting device of pneumatic engine is to use commonplace a kind of pneumatic starting device on automobile, and it designs on the clutch bell and flywheel of driving engine.Its principle of work is: utilizes pressurized air that the engine flywheel blade is applied circumference thrust along the flywheel rotation direction, forces the flywheel running and reach certain rotating speed, thus fire an engine.This starting device both can be used as main starting device use and also can be used as standby or the auxiliary starting device use.Its general structure is: process air inlet main stem and air inlet by-path on flywheel fwd flywheel shell, being installed into gas-tpe fitting at the admission port place is connected with shunt valve by pipeline, at processing of flywheel front or installation impeller, allow air inlet by-path exit just in time aim at impeller, and guarantee gas shock direction-adapting flywheel rotation direction; Impeller vane should tilt against the flywheel rotation direction, and with the inner envelope shelves of the groove between adjacent two blades, the outer end is opened wide, utilize the air pressure energy when this structure helps starting fully and effectively, do not influence engine operation efficient when also helping engine running because of impeller produces big air resistance; Also should add soil on the clutch bell and go out and the cooresponding envelope compression of impeller, wipe under the prerequisite bump not producing, must cooperate closely between impeller and the envelope compression as far as possible, make the raising of pressurized air degree of utilization; In time discharge for making behind the compressed air to do work, freeing pipe makes in flywheel protecting cover lower left, and comply with combustion gas flow to, freeing pipe is than the thick several times of air inlet pipe.When carrying out pneumatic starting, pressurized air from shunt valve successively through air inlet pipe, inlet channel enters each air inlet by-path, discharge from a road junction, the pressurized air of discharging applies the thrust of circumferencial direction near the blade the road junction, force the flywheel running, pressurized air after the acting forwards the clutch bell below to, enters high pressure gas secondary use device from freeing pipe, and is higher at compressed-air actuated pressure, under the situation of tolerance abundance, because high pressure gas is constantly carried acting, impel flywheel constantly to turn round, and reach certain rotating speed, thereby make driving engine by starting operation, in this case, the pneumatic starting device just uses as main starting device; Under the situation lower at compressed air pressure, that tolerance is not enough, the load of starter when utilizing pressurized air can alleviate starting, in this case, the pneumatic starting device makes as auxiliary starting device and uses.The same with the traction servo-unit, can carry out the secondary utilization for exhaust, just do not give unnecessary details at this.

The pressurized air air inlet boosting device is the device that the exhaust of drawing servo-unit and the outer air pressure lifting device of machine on the diesel-powered vehicle is utilized again, it is one of high pressure gas secondary use device noted earlier, its design is on the diesel motor air inlet pipe, communicate by pipeline with the freeing pipe of traction servo-unit and the outer pneumatic starting device of machine, supercharging mode can be divided into direct pressure charged and indirect pressure charged, that is: for the diesel motor that does not originally assemble blwr, the exhaust of above-mentioned two devices directly can be poured into air inlet pipe and carry out direct plenum; For the diesel motor that blwr was installed originally, both can as above carry out direct supercharging, also the exhaust of above-mentioned two devices can be passed through impulsion supercharger rotor impeller, diesel motor is carried out indirect plenum.Should assemble unidirectional autochoke at the admission port place that communicates with above-mentioned two devices freeing pipe, also should assemble unidirectional autochoke at the admission port place that communicates with airfilter, if any supercharger structure, also should assemble two manual chokes, by a backguy operation control, and set up the pressurized air turbo-machine.The pressurized air turbo-machine can copy exhaust turbine to construct, and makes two turbo-machine symmetrical balances, both can the running of independent drive air compressor, also transmission air compressor running together.When using the traction servo-unit to draw power-assisted, or when the pneumatic starting device starts outside the use machine, the pressurized air that arbitrary device is discharged can be opened corresponding strangler valve automatically, close and make another install corresponding strangler valve, as there is not a supercharger structure, the strangler valve that then leads to fil also can SELF CL, pressurized air makes and directly is pressed into cylinder and carries out the direct-type plenum, if any supercharger structure, can be by the corresponding manually strangler valve of operation, both can also can carry out indirect supercharging as preceding carrying out direct supercharging by impulsion worm gear machine impeller.

Each parameters of operating part of the above high-pressure air intake apparatus is decided by concrete vehicle, and the selection aspect can will be described further about the configuration aspects back with reference to the accompanying drawings with reference to automobile construction.
