201410115908.7 patent document described in a kind of three-position four-way electromagnetic directional valve.
Operation principle is as follows：
When the bilateral intake type turbocharger does not work, as shown in Figure 1 and Figure 7, reversal valve 8-4 is in opposite and connects
Logical working position 8-43 working conditions, first inner chamber 8-11 are connected by first inner chamber pipe 8-13 and reversal valve 8-4 and high-voltage tube 8-51
Logical, second inner chamber 8-12 is connected to by second inner chamber pipe 8-14 and reversal valve 8-4 with low-voltage tube 8-52, and hydraulic pump unit 8-5 is defeated
The hydraulic oil with setting pressure gone out is flowed into through high-voltage tube 8-51, reversal valve 8-4 and first inner chamber pipe 8-13 in first successively
Chamber 8-11, while the hydraulic oil in second inner chamber 8-12 is returned through second inner chamber pipe 8-14, reversal valve 8-4, low-voltage tube 8-52 successively
It flow in the oil storage tank of hydraulic pump unit 8-5, then piston 8-2 is moved to second inner chamber 8-12；
Then, into air driving device：Piston 8-2 by control-rod 8-3 drive air inlet turbine 6 from air intake duct 1-2 be moved into
Gas accommodating groove 1-3, charge air flow flow into air intake duct 1-2 from front side air intake duct 2, then flow into rear side air intake duct 3, because of air inlet turbine 6
It is moved to air inlet accommodating groove 1-3 from air intake duct 1-2, avoids air inlet turbine 6 in air intake duct 1-2 to flow velocity originally very low air inlet
Air-flow generates resistance, improves intake efficiency；
Then, exhaust gas drive device：Piston 8-2 drives exhaust driven gas turbine 7 to be moved to row from exhaust duct 1-1 by control-rod 8-3
Gas accommodating groove 1-4, exhaust airstream flow into exhaust duct 1-1 from front side exhaust duct 4, then flow into rear side exhaust duct 5, because of exhaust driven gas turbine 7

So that the exhaust gas in cylinder is discharged more thorough, reduce remaining exhausted air quantity in cylinder, improves exhaust efficiency.
When the bilateral intake type turbocharger works, as shown in Figure 4 and Figure 6, reversal valve 8-4 is in intersect and be connected to
Working position 8-41 working conditions, second inner chamber 8-12 are connected to by second inner chamber pipe 8-14 and reversal valve 8-4 with high-voltage tube 8-51,
First inner chamber 8-11 is connected to by first inner chamber pipe 8-13 and reversal valve 8-4 with low-voltage tube 8-52, hydraulic pump unit 8-5 outputs
Hydraulic oil with setting pressure flows into second inner chamber 8- through high-voltage tube 8-51, reversal valve 8-4 and second inner chamber pipe 8-14 successively
Hydraulic oil in 12, first inner chamber 8-11 is back to hydraulic pressure through first inner chamber pipe 8-14, reversal valve 8-4, low-voltage tube 8-52 successively
In the oil storage tank of pump unit 8-5, then piston 8-2 is moved to first inner chamber 8-11；
Then, into air driving device：Piston 8-2 drives air inlet turbine 6 to be moved from air inlet accommodating groove 1-3 by control-rod 8-3
To air intake duct 1-2, different pressure is set by the hydraulic oil exported to hydraulic pump unit 8-5, control hydraulic pump unit 8-5's
Pump oil mass, the displacement of control piston 8-2 controls the displacement that air inlet turbine 6 enters air intake duct 1-2, to control into
Supercharging value of the air turbine 6 to charge air flow in air intake duct 1-2.After engine start, discharge exhaust gas enter exhaust duct 1-1 and drive
Dynamic exhaust driven gas turbine 7 rotates, and since air inlet turbine 6 is always maintained at the drive connection with exhaust driven gas turbine 7, air inlet turbine 6 follows exhaust
7 synchronous rotary of turbine.As air inlet turbine 6 is moved from air inlet accommodating groove 1-3 to air intake duct 1-2, the blade and stream of air inlet turbine 6
It is incrementally increased through the gas-contact area in air intake duct 1-2, the supercharging value that air inlet turbine 6 generates the gas in air intake duct 1-2
Also it incrementally increases.It will be apparent that blade of the supercharging value with air inlet turbine 6 and the close phase of gas-contact area in air intake duct 1-2
It closes, therefore the part of air inlet turbine 6 into air intake duct 1-2 are more, then it is bigger to the supercharging value of gas generation.It is after supercharged into
Gas air-flow flows into rear side air intake duct 3, and can be played along the axial displacement of air inlet transmission shaft 9 by adjusting air inlet turbine 6 can
The supercharging effect of control；
Then, exhaust gas drive device：Piston 8-2 drives exhaust driven gas turbine 7 from exhaust accommodating groove 1-4 movements by control-rod 8-3
To exhaust duct 1-1, different pressure is set by the hydraulic oil exported to hydraulic pump unit 8-5, control hydraulic pump unit 8-5's
Oil mass is pumped, the displacement of control piston 8-2 controls the displacement that exhaust driven gas turbine 7 enters exhaust duct 1-1, to the row of control
Gas air-flow adjusts the rotating speed of exhaust driven gas turbine 7 to the impact force of exhaust driven gas turbine 7, to pass through exhaust-driven axis 10, air inlet transmission shaft
9 adjust the rotating speed of air inlet turbine 6.As exhaust driven gas turbine 7 is moved from exhaust accommodating groove 1-4 to exhaust duct 1-1, exhaust driven gas turbine 7
Blade is incrementally increased with the contact area for flowing through exhaust gas in exhaust duct 1-1, and the exhaust gas with certain pressure is to 7 blade of exhaust driven gas turbine
The impact force of generation also incrementally increases, and 7 rotating speed of exhaust driven gas turbine incrementally increases, and increases to make the rotating speed of air inlet turbine 6 synchronize, makes
Air inlet turbine 6 generates the supercharging value of bigger.It will be apparent that blade of the supercharging value with exhaust driven gas turbine 7 and the exhaust gas in exhaust duct 1-1
Contact area is closely related, therefore the part of exhaust driven gas turbine 7 into exhaust duct 1-1 are more, for improving the supercharging of air inlet turbine 6
Value is obviously promoted effect., whereas if needing the supercharging value of reduction air inlet turbine 6, exhaust driven gas turbine 7 can be made to be stored to exhaust
Slot 1-4 movements reduce exhaust driven gas turbine 7 and are located at the part in exhaust duct 1-1, that is, reduce the exhaust whirlpool that percussion occurs with exhaust gas
Blade area on wheel 7.Therefore, supercharging can be adjusted along the axial displacement of exhaust-driven axis 10 by adjusting exhaust driven gas turbine 7
Effect.
