hydraulic fluid is filled between the sliding plug 510 and the inner top surface of the sliding cavity;

specifically, in the initial state of the self-aligning member 5, the solenoid valve 509 is closed, the hydraulic fluid cannot be discharged, and the spool is not affected by the resilient force of the spring 502, thereby achieving the fixation.

In this embodiment, the elbow 6 is provided with 4 bends for stretch compensation.

In this embodiment, the outer wall of the sliding plug 510 is provided with an annular groove, and a sealing ring is installed in the annular groove.

In the embodiment, the annular cavity can contain 4/5 of the total volume of the hydraulic fluid in the sliding cavity;
