Specific embodiment
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with novel.
As depicted in figs. 1 and 2, inside valve body 1 be provided with three cavitys and five nozzles, three cavitys include oil pocket 14,
First gas chamber 4 and the second gas chamber 7, five nozzles are the first port 5, the second port 6, oil inlet 13, oil outlet 9 and connection respectively
Oil pipe mouth 12, oil pocket 14 are connected to by oil inlet 13 with oil outlet 9, and oil pocket 14 and the first gas chamber 4 and 7 junction of the second gas chamber are equal
Be provided with sealing ring 15, the first port 5 and the second port 6 be located at 1 inside two sides of valve body and with 2 coaxial line of spool, first
Port 5 and the second port 6 are connected to the first gas chamber 4 and the second gas chamber 7 respectively, and oil inlet 13 and oil outlet 9 are located in valve body 1
On the upside of portion and vertical with the axis of spool 2, connected pipes mouth 12 connects between oil inlet 13 and oil outlet 9 and with oil inlet 13
It is logical, it is provided with non-return valve 11 in connected pipes mouth 12, is provided with guide sleeve 10 in connected pipes mouth 12, spool 2 is being located at the
The left and right ends of one gas chamber 4 and the second gas chamber 7 are respectively arranged with first back-moving spring 3 and second back-moving spring 8, as shown in figure 3,
Spool 2 includes first piston 21, first annular piece 22, the spool body of rod 23, the second ring block 24 and second piston 25, first piston
21 and second piston 25 be located at the both ends of spool 2, first annular piece 22 and the second ring block 24 are arranged at intervals on valve core rod
