Principle of work

One, startup and off-position:

During startup, open the gas source switch 17 that is connected with high-pressure work source of the gas 18 earlier, shown in Fig. 1, Figure 12-1, Figure 12-3, high pressure draft gets into the P1 chamber of makeshift valve 14 as shown in Figure 4, and gets into the P2 chamber through free air diffuser 57,58; When position as shown in Figure 4, slide block 48 places, the air pressure in the P2 chamber is by pore B11 output, through B11-A1 gas circuit shown in Figure 3 A1 chamber air feed to the main valve body 28 of swing reservoir, orders about piston 29 and tooth bar 31 moves right, and the working gear 27 that is engaged in tooth bar 31 clockwise rotates thereupon; Simultaneously the air pressure in the B1 chamber is in the pressure release state, because the pore A11 on the swing reservoir 13, O1, B11 become one-to-one relationship with A11, O1, B11 on the makeshift valve 14, the Pneumatic pipe cleaner in the B1 chamber is crossed the slide block 48 top spill chambers 52 of B1-A11 entering makeshift valve 14, changes the O1 hole of swinging reservoir main valve body 28 again over to, discharges from O11 through the O1-O11 path again; When working gear 27 forwarded 90 ° of setting to, promptly piston 29 had arrived low order end, and the telltale hole K2 in the A1 air cavity is opened, and air pressure flows into K23 from K2, when Windshield Wiper is directly to control standard; Air pressure among the K23 just flows into off-position control cock 15, K21 pore as shown in Figure 6, and through the C1 air chamber of off-position valve opening 61 entering K22 and control plunger 46, under gas pressure, control plunger 46 drives slide blocks 48 and moves to right together; The B11 pore gets in the spill chamber 52 on the slide block 48 subsequently, then gets into the O1 hole of swing reservoir 13, is contained in sound-deadened exhaust governor valve 16 emptyings of being with on the O11 through final entering of O1-O11 gas control, and after slide block 48 moved to right, work source of the gas 18 got into A11 simultaneously; Get into the B1 air chamber in the swing reservoir through A11-B1, under gas pressure, piston 29 moves to left together with tooth bar 31, and work rotating shaft 19 rotates counterclockwise, when waiting to go back to 90 °; Telltale hole K1 in the B1 air cavity is opened, and the air pressure in the K2 path is from the middle part emptying of swing reservoir, and the air pressure stream among the K1 changes K11, K12 in each valve 14 over to again to K11, and control plunger 46 moves to left together with slide block 48 under gas pressure; Linked up A11, O1 gas circuit again, B11 transfers air inlet once more to, and along with A11, B11 replace air inlet, K1, K2 signal alternately occur; Piston 29 in control plunger 46 in the makeshift valve 14 and the swing reservoir 13 alternately switching-over moves, and has driven work rotating shaft 19 round rotations, puts rain (snow) water on the brush windshield again and again thereby drive rain brush 1, makes driver's sight line transparent; In the time will stopping Windshield Wiper work, can push the off-position handle 67 on the off-position control cock 15, make off-position valve rod 65 move to spacing ring 66 inwards, K21 is in not vent passage mutually with K22; Makeshift valve 14 can't commutate because of no control signal, and swing reservoir 13 does not stop because of there being switching-over air pressure yet, and rain brush 1 just is parked on the position on a former predetermined left side or the right, when Windshield Wiper is the Long-distance Control type automatically as a result; The off-position of Windshield Wiper will adopt the off-position structure shown in Fig. 9, Figure 12-1 and Figure 12-3 in the off-position speed governing combine valve 113, and will the control cover plate 44-1 on the makeshift valve 14 be changed into remote control cover plate 44-2, when off-position handle 91 is in the lower position, from off-position admission port 95; Be P2, the air pressure of coming in is behind off-position free air diffuser 94, air inlet chamber 93, off-position outlet passageway 98, by off-position air extractor duct 96, i.e. P3; Output to the joint air flue 87 in the remote-type coupling 84 of remote control cover plate 44-2, i.e. P4, air pressure overcomes the elastic force of off-position spring 116, and the remote control piston 79 among the remote control cover plate 44-2 is moved to left; Make K23 and K24 obstructed, the air chamber C1 that the air pressure that K23 is can not control of access piston 46, makeshift valve 14 can't commutate, and stops swinging behind rain brush 1 self-return; If off-position hand 91 upwards is drawn out to plug screw 103 upper limit positions, the outer air chamber of remote control piston 79 this moment 88, joint air flue 87, PU manage 86, and the air pressure in off-position air extractor duct 96 and the off-position outlet passageway 98 can only be discharged from drain 97, and remote control piston 79 is owing to two ends compression face product moment is pushed to right-hand member; Thereby connect K23 and K24 path, the K24 in the makeshift valve 14 has had air pressure signal and has been in normal commutation, and the piston 29 in the corresponding swing reservoir 13 is movement therewith also, and rain brush 1 is normally swing thereupon.

Also available hand shown in Figure 13 behaviour rotary valve 117 structures of will start new type pneumatic wiper, off-position being controlled; Figure 13-the 1st, the distribution plate 122 ventilation annular grooves on the hand behaviour rotary valve 117; Be the upward view of K-K section, the hole on 122 of the distribution plates is connected Figure 13-the 2nd, the birds-eye view of K-K section with air flue 128; Annular groove on the pottery air dividing plate 120 drives ceramic air dividing plate 120 through turning knob 118; Can reach equally and Windshield Wiper shown in Figure 9 startup and the same function of off-position, knob 118 is rotatable, and spacing with fix shaft 129.

Two, frequency modulation and speed governing:

It is very simple that the Windshield Wiper of directly controlling standard is carried out the frequency-adjustable speed-adjustable method: according to the rain on the Windshield (snow) water yield trace, rotation shown in Figure 11-1 with the hand wheel type metering needle 76 on the sound-deadened exhaust governor valve 16, just can obtain glass transparent degree wobble frequency slew rate preferably; The rain brush 1 of Long-distance Control is carried out frequency-adjustable speed-adjustable both can adopt the speed regulating structure shown in Figure 10 or Figure 12-2 and Figure 12-4: rotate speed handwheel 102, the air-flow through speed governing admission port 110, speed governing free air diffuser road 109 to the O11 pore output from swing reservoir 13 carries out throttling through timing throttle pin 112; The final speed governing air inlet chamber 111 that gets into; Throttle opening is more little, and rain brush 1 wobble frequency slew rate is more little, and throttle opening is big more; The wobble frequency slew rate is just big more; The driver can carry out step-less adjustment according to the rain on the windshield (snow) water yield, in addition, and in order to reduce exhaust roar; Can connect at the O11 of speed governing air extractor duct 107 screw and be with sound-deadened exhaust governor valve 16; But want standard-sized sheet hand wheel type metering needle 76 shown in Figure 7, to the pneumatic remote control system 115 of the also available band spray of the new type pneumatic wiper frequency-adjustable speed-adjustable of Long-distance Control, the pneumatic remote control system 115 of band spray is made up of hand behaviour rotary valve 117, pneumatic spray assembly 127 and exhaust governor valve 126 etc.; Frequency-adjustable speed-adjustable is with the knob on the exhaust governor valve 126, and micro-rotation can be played the adjusting requirement.

Three, spray:

Pneumatic spray assembly 127 has two kinds of structures, and the one, the pneumatic spray 127-1 of vapour-pressure type, it is made up of pneumatic storage tank 131 and the pneumatic push buttonvalve 139 of two-position three way; The pneumatic push buttonvalve 139 of two-position three way will be contained on the remote manipulation panel, when using spray, presses the button on the pneumatic push buttonvalve 139 of two-position three way; Pneumatic pipe cleaner is crossed the last space that pipeline process air inlet screw 136 is added in pneumatic storage tank 131 tanks 134, and the water in the tank 134 is pressed into the shower 157 that places on the brush holder support 3 through water outlet screw 137 under gas pressure; Water is sprayed on the Windshield face, and behind the startup Windshield Wiper, the dirt on the Windshield is swept to the greatest extent; Another kind is the pneumatic spray 130 of water tank type, and it is made up of with spray air valve 140 2 parts shown in figure 15 the pneumatic push buttonvalve 139 of two-position three way, when using spray; Press the button on the pneumatic push buttonvalve 139 of two-position three way with hand, air pressure is divided into two the tunnel, the one tunnel and gets into air flue N1 behind screw P7; Diaphragm 148 is sealed the nozzle 158 on the nozzle valve body 145 under the effect of air pressure, thereby has closed the water-flowing path that flows into water cavity W1 from water tank 156; Another road of air pressure gets into the right air chamber N5 of pneumaticpiston 142 through air flue N2, N3, N4; Pneumaticpiston 142 overcomes under gas pressure behind the elastic force of spring 153 to left movement, and the water that is stored among the water cavity W1 is pressed into shower 157 through screw P6, finally sprays on Windshield; After starting Windshield Wiper; Dirt on glass also can be swept only, as the pneumatic push buttonvalve 139 of the two-position three way of letting go, and compressed gas among air flue road N1, N2, N3, N4 and the air chamber N5 is known from experience very soon through screw P7 from pneumatic push buttonvalve 139 emptyings of two-position three way; Thereby link up the water cavity path of W2 and W3, be in water in the elevated tank 156 inflow water cavity W1 that takes advantage of a situation.

Elsewhere; Straight behaviour's formula Windshield Wiper also can adopt any in two kinds of above-mentioned pneumatic spray assemblies 127 to spray control, or the pneumatic spray 127-1 of vapour-pressure type, or the pneumatic spray 130 of water tank type; But the pneumatic push buttonvalve 139 of two-position three way will be contained on the remote manipulation panel, so that operation.

Adopt the spray of the Long-distance Control Windshield Wiper of off-position speed governing combine valve 113; All can adopt the pneumatic spray 127-1 of vapour-pressure type on the remote manipulation face of being contained in, perhaps the pneumatic spray 130 of water tank type uses when spraying; Press the button on the pneumatic push buttonvalve 139 of two-position three way; Can the water among water in the tank 134 or the spray air valve 140 water cavity W1 be sprayed onto on the Windshield, start Windshield Wiper after, dirt on glass also will be swept and clean.
