Specific implementation mode
For a better understanding and implementation, being further described below in conjunction with the accompanying drawings to the utility model：A kind of oil cylinder
Speed enhancing apparatus, including oil cylinder 2, oil pump 3 and fuel tank 4, are arranged integrated package 1, and the integrated package 1 includes reversal valve I 5, reversal valve II
6, reversal valve I 5 is equipped with tetra- oilhole A17, oilhole B18, oilhole T9 and oilhole P110 oilholes, and reversal valve II 6 is equipped with oilhole
A211, oilhole B212 and tri- oilholes of oilhole P213, when oil cylinder idle stroke, oilhole A1 7 respectively with oilhole A2 11 and oil cylinder
2 A oilholes communicate, and the oilhole B of oil cylinder 2 is communicated with oilhole P2 13, and oilhole A2 11 is communicated with oilhole P2 13；
When oil cylinder idle stroke, the oil in fuel tank 4 enters oilhole P1 10 by oil pump 3, and oil enters oil from oilhole P1 10
Hole A1 7 divides two-way from oilhole A1 7, enters oilhole A2 11 all the way, enters the A oilholes in oil cylinder 2 all the way（That is rodless cavity）,
From the oilhole B of oil cylinder 2（That is rod chamber）Enter A2 11 into oilhole P2 13, oilhole P2 13, oil enters oil cylinder from A1 7 again
The holes A in 2；
When being connected to the signal of pressure sensor, reversal valve II 6 commutates, and oilhole A1 7 continues and oilhole A2 11 and oil
The oilhole A of cylinder 2 is communicated, and the oilhole B of oil cylinder 2 is communicated with oilhole P2 13, and oilhole A2 11 and oilhole P2 13 is cut off not
Logical, oilhole P1 10 is communicated with oilhole A1 7, and oilhole B1 8 is communicated with oilhole B2 12 and oilhole T 9 respectively, oilhole B2
