The C chamber of depressor 3, and A, B chamber connection of ratio booster 3 and T1, B1 mouth company through T2 mouthfuls of supercharger unit, solenoid directional control valve 1
Logical oil return fuel tank, so A, B chamber do not have pressure, the piston of ratio booster 3, which is moved to the left, makes C chamber suction pressure；Piston is mobile
Differential type hydraulic reversal valve 6 commutates when having pressure to the first pilot circuit 7, and pressure passes through the P3 mouth of differential type hydraulic reversal valve 6
The A chamber of ratio booster 3 is filled with through S3 mouthfuls, due to the corresponding piston area of A chamber be greater than the corresponding piston area of C chamber, piston to
It moves right and is filled with hydraulic to the circuit HP, complete pressurization.
When pressure release, solenoid directional control valve 1 gives 24V voltage, and solenoid valve is obtained electric and commutated, and A1, T1 mouth of solenoid directional control valve 1 are led
Logical, B1, P1 mouthfuls of conductings, thus P1 mouthfuls of connected tank oil returns, accumulator 2 releases stress the T1 mouth through solenoid directional control valve 1 and enters pressurization
Device unit, third pilot circuit 10 has pressure at this time, and the pressure of third pilot circuit 10 opens hydraulic control one-way valve 9 enough keeps its complete
At commutation work, hydraulic control one-way valve 9 is connected from right to left, so that HP system pressure is through hydraulic control one-way valve 9 through supercharger unit P2
Mouthful P1, B1 mouth oil return box through solenoid valve reversal valve 1, completion pressure leak process, whole process, which does not need to restart motor, provides pressure
Power, the pressure of accumulator 2 complete pressure release work enough.
