[0007] The present invention will be further explained below in conjunction with the drawings.
[0008] Such as figure 1 Shown is the structural diagram of the present invention, which includes an oil pump 1, an overflow valve 2, a solenoid valve 3, a sequence valve 4 and a hydraulic cylinder 5. An overflow is provided between the output end of the oil pump 1 and the input end of the solenoid valve 3 Valve 2, the output end of the solenoid valve 3 is connected to the input end of the sequence valve 4, the output end of the sequence valve 4 is connected to one end of the hydraulic cylinder 5, and the other end of the hydraulic cylinder 5 is connected to the solenoid valve 3.
[0009] Such as figure 1 As shown, the adjustment pressure of sequence valve 4 should be slightly greater than the pressure of the 5 lower chamber stroke of the working part mass in the hydraulic pressure. When the dead weight is large, the pressure of sequence valve 4 needs to be adjusted higher, and when the...
