Example Embodiment
[0026] Example 1.
[0027] see Figure 1~3 , This embodiment includes a valve body 1 ( figure 2 Shown), the first ferrule 19 ( image 3 Shown).
[0028] One end of the valve body 1 is provided with an inner cavity, and the inner cavity is composed of a first insertion hole P1, a first oil cavity K, a control piston mounting hole t, and a second oil cavity m from left to right.
[0029] see figure 1 , 2 , The first oil port A1 is in communication with the first oil chamber K, the second oil port A2 is in communication with the first insertion hole P1, and the third oil port B1 and the fourth oil port B2 are respectively in communication with the second oil chamber m.
[0030] see figure 1 , 2 , The first insert 19 is installed in the first insert hole P1; the first porous plate 15 is pressed by the first insert 19 on the first positioning end surface S1 of the valve body 1 (see the first positioning end surface S1 figure 2 ).
[0031] The control piston 18 is installed in the control ...
Example Embodiment
[0043] Example 2.
[0044] see figure 2 , 4 5. The valve body 1 in this embodiment is the same as the valve body in embodiment 1, except that the first insert 19 also includes a fourth spring 8, a spring guide rod 12, and a pressure relief valve 13. , Pressure relief hole j. Among them, the pressure relief hole j is provided in the middle of the front end of the main valve core 10, and the back end of the pressure relief hole j is provided with a pressure relief valve 13, a spring guide rod 12 and a fourth spring 8. The fourth spring 8 compresses the pressure relief valve 13 On the pressure relief hole j.
[0045] In this embodiment, the pressure relief valve 13 is opened first to relieve the pressure of the fourth oil chamber f, and then the main valve core 10 is opened. In Embodiment 1, the main valve core 10 is first opened to relieve the pressure of the fourth oil chamber f through the orifice n. Because the pressure-receiving area of the pressure relief valve 13 is much ...
Example Embodiment
[0050] Example 3.
[0051] see Image 6 , 7 And see image 3 The first ferrule, the first ferrule in this embodiment is the same as the first ferrule in the first embodiment.
[0052] The difference between this embodiment and embodiment 1 is that the front end of the second oil chamber m is also connected with a second insertion hole P2 having the same structure as the first insertion hole P1, and a second ferrule having the same structure as the first insertion hole 19 20 is installed in the second insertion hole P2; the second porous plate 155 is pressed by the second insert core 20 on the second positioning end surface S2 of the valve body 1. A second limit pad 177 is provided at the front end of the control piston 18. The fifth spring 166 is installed between the second limiting pad 177 and the second porous plate 155, and the fourth oil port B2 is in communication with the second inserting hole P2.
[0053] Embodiment 1 can only control one cavity of the oil cylinder, and can...
