Further as preferred embodiment, shared same primary stage port 11 of two secondary automatically controlled relay valves on the main body 1 and control gas port 13.That is to say in the structure that the utility model provides, 11 1 of primary stage ports are arranged, 13 1 of gas ports of control, air extractor duct 14, exhausr port 15, Movable valve 4, main control piston 5, the air chamber 3 each two received.Certainly, described left and right sides looking-glass symmetry is arranged and is only represented this structure compact, makes things convenient for processing; If other more excellent structure layouts are arranged; Perhaps increase, merge some gas ports more,, also belong to the variant that is equal to of the utility model as long as meet twin-channel gas circuit design concept.
With reference to Fig. 2; Particularly; Said Movable valve 4 is so a kind of structures; It has main casing lining 7 and the annular piston 41 that is enclosed within outside the main casing lining 7, is provided with compression spring 6 between said main casing lining 7 and the annular piston 41, and the elastic force of said compression spring 6 pushes up annular piston 41 toward the directions away from main casing lining 7.Left-half with the expressed sectional structure of Fig. 2 is an example, and main control piston 5 is being received slippage in the air chamber 3, and its integral body will be received air chamber 3 and be separated into two parts, a part with control gas port 13 and be communicated with; Be called the G chamber, its cooresponding pressure be P1 (accordingly, the right side of main body 1 receive air chamber 3, be called the G1 chamber; Pressure is P3), another part is communicated with the air extractor duct 14 on the left side, is called the K chamber, its cooresponding pressure be P2 (accordingly; The right side of main body 1 receive air chamber 3, be called the K1 chamber, pressure is P4); Main control piston 5 has aim at Movable valve 4 long protruding, and when main control piston 5 moved toward position, K chamber, long convexity promptly can be backed down Movable valve 4; Thereby primary stage port 11, K chamber are communicated with the air extractor duct 14 on the left side, otherwise Movable valve 4 reset pathway closure; In addition, when the long convexity of main control piston 5 contacts with annular piston 41, will close the air extractor duct 14 on the left side and the interface channel of exhausr port 15; Accordingly, the principle of work on main body 1 right side is identical.
Further as preferred embodiment, said electromagnetic valve group 12 comprises three moving iron core M1, M2, M3, said three moving iron core M1, M2, M3 control receive air chamber 3 with control whether being communicated with and controlling whether being communicated with of gas port 13 and exhausr port 15 of gas port 13.With reference to Fig. 4, in the middle of moving iron core M1 is positioned at, about be iron core M2 and moving iron core M3 respectively, when moving iron core moved, it closed passage; When it was failure to actuate, passage was opened.
Set forth the working process of the utility model below:
1. brake-pressure increases process
1-1. supercharging simultaneously
When gently stepping on automobile brake pedal, three moving iron core M1, M2, M3 are failure to actuate, and this moment, primary stage port 11 maintained high pressure gas; Control gas port 13 and feed high pressure gas, high pressure gas gets into G chamber, G1 chamber through moving iron core M1, M2, M3 respectively, at this moment P1＞P2, P3＞P4; Main control piston 5 is moved and oppresses compression spring 6; Push open with being about to annular piston 41, valve is corresponding to be opened, and primary stage port 11 communicates with K chamber, K1 chamber and promptly communicates with air extractor duct 14; Air extractor duct 14 pressure increase, and promptly the pressure in the compressed air brake cylinder of automobile increases sharply; At this moment, about two secondary automatically controlled relay valves all work simultaneously.
1-2. supercharging separately
Two secondary automatically controlled relay valves can work independently about in the utility model; As when not wanting that left side air extractor duct to relay valve carries out supercharging; Moving iron core M2 action does not then have high pressure gas and gets into the G chamber, and the annular piston 41 on the left side is not pushed open by main control piston 5; Primary stage port 11 is obstructed promptly obstructed with left side air extractor duct 14 with the K chamber, and air extractor duct 14 pressure in left side do not increase; Moving iron core M3 is failure to actuate; High pressure gas gets into the G1 chamber; The annular piston 41 on the right is pushed open by main control piston 5, and corresponding valve is corresponding to be opened, and primary stage port 11 communicates with the K1 chamber and promptly communicates with right side air extractor duct 14; Air extractor duct 14 pressure in right side increase, on the contrary when not wanting to carry out supercharging to right side air extractor duct 14 then.
2. pressure maintaining period
2-1. pressurize simultaneously
After control gas port 13 feeds high pressure gas; Moving iron core M1 is failure to actuate, moving iron core M2, M3 action, and G chamber, G1 chamber are closed with the path of control gas port 13; It has pressure P 1, P3; Compression spring resets when P1=P2, P3=P4, corresponding valve closing, and primary stage port 11 and K chamber, K1 chamber are obstructed promptly obstructed with air extractor duct 14.This moment, air extractor duct 14 did not communicate with exhausr port 15 yet, and the pressure of air extractor duct 14 is maintained.
2-2. pressurize separately
The utility model can carry out pressurize to the air extractor duct 14 of either side.When only left side air extractor duct 14 being carried out pressurize; After control gas port 13 feeds high pressure gas, then moving iron core M2 action, the G chamber is closed with the intake channel of control gas port 13; Left side compression spring 6 resets when P1=P2; Corresponding valve closing, primary stage port 11 is obstructed promptly obstructed with left side air extractor duct 14 with the K chamber, and air extractor duct 14 pressure in left side are maintained.To have two kind situation to the control of right side air extractor duct 14 pressure this moment, and the one, moving iron core M1, M3 are failure to actuate, and right side air extractor duct 14 continues the entering pressurize that resets of superchargings the right compression spring 6 when P3=P4; The 2nd, moving iron core M1 action, the air inlet of control gas port 13 is closed, and moving iron core M3 is failure to actuate; The K1 cavity pressure discharges through exhausr port 15, and < P4, the right main control piston 5 move to the most initial position to cause P3; Corresponding valve open, the pressure of right side air extractor duct 14 discharges through exhausr port 15.Otherwise when only right side air extractor duct 14 being carried out pressurize and left side air extractor duct 14 is carried out control corresponding then.
3. decompression process
3-1. decompression simultaneously
3-2. decompression separately
The utility model can reduce pressure to the air extractor duct 14 of either side, and as only being given vent to anger in the left side, 14 reduce pressure, moving iron core M1 action, and the air inlet of control gas port 13 is closed, and the valve below it is opened; Moving iron core M2 is failure to actuate, and the G cavity pressure discharges through exhausr port 15, and < P2, the main control piston 5 on the left side move to the most initial position, and corresponding valve open, the pressure of left side air extractor duct 14 pass through exhausr port 15 and discharge, and the pressure of left side air extractor duct 14 reduces to cause P1; Moving iron core M3 action; This moment, the G1 chamber was all obstructed with control gas port 13, exhausr port 15; Its pressure that has is P3, the compression spring 6 that right side air extractor duct 14 continues superchargings the right when the P3=P4 entering pressurize that resets, otherwise as only right side air extractor duct 14 being reduced pressure control corresponding then.
More than be that preferred embodiments to the utility model specifies; But the invention is not limited to said embodiment; Those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
