Right pressurized cylinder 13 forms, and piston 2 is set in piston cylinder 11, and left piston bar 3 is set in left booster cavity, and right piston bar 4 is arranged
In in right pressurized cylinder 13, left piston chamber 6 and right piston chamber 7, left piston bar 3 and left pressurization are formed between piston 2 and piston cylinder 11
Left booster cavity 8 is formed between cylinder 12, and right booster cavity 9 is formed between right piston bar 4 and right pressurized cylinder 13.
Pilot operated directional control valve 10 be two-position four-way pilot operated directional control valve, p, T mouthfuls of connection oil return lines of P mouthfuls of connection low pressure lines, A mouthfuls
It is connect with left piston chamber 6, B mouthfuls connect with right piston chamber 7.
Left pressurized cylinder 12 opens left control mouth 16, and right pressurized cylinder 13 opens right control mouth 17, and left control mouth 16 connects liquid controlled reversing
10 left side pilot port of valve, 19 pilot port of left overflow valve 14, the first hydraulic control one-way valve 18 and the second hydraulic control one-way valve, right control mouth 17
Connect 10 right side pilot port of pilot operated directional control valve, 18 guide of right overflow valve 15, the second hydraulic control one-way valve 19 and the first hydraulic control one-way valve
Mouthful, left overflow valve 14, right overflow valve 15, the first hydraulic control one-way valve 18, the second hydraulic control one-way valve 19 connect drain line X.
Such as Fig. 1, when booster work, the first hydraulic control one-way valve pilot port no pressure, the first hydraulic control one-way valve is closed, low

When intensifier piston bar movement is such as the position Fig. 2, left control mouth and left pressurized cylinder are disconnected, right control mouth with
Right booster cavity connection, the second hydraulic control one-way valve pilot port pressure reduce, and the second hydraulic control one-way valve is closed, pressure in low pressure oil way p
Oil enters pilot port and the first hydraulic control one-way valve pilot port, the first liquid on the right side of pilot operated directional control valve by right booster cavity, right control mouth
It controls check valve to open, pilot port is connect by the first hydraulic control one-way valve with drain line X on the left of pilot operated directional control valve, pilot operated directional control valve
Spool is in right position, and P mouthfuls logical with A mouthfuls, and T mouthfuls logical with B mouthfuls, and pressure oil enters left pressurization by pilot operated directional control valve in low pressure oil way
Chamber pushes piston to move right, and for right piston chamber by B mouthfuls, T mouthfuls of oil returns, right booster cavity pressurization is so constantly reciprocal, lasting to increase
Pressure.
The effect of left and right overflow valve is to protect pilot operated directional control valve not by impacting with high pressure, can also remove, left and right control mouth
Specific location by equipment parameters depending on.
