Fig. 2 is to remove the A-A of chain in Fig. 1 to sectional view.
Specific embodiment
Embodiment：High pulling torque U-shaped hydraulic gyration mechanism as depicted, including cylinder body 1, described cylinder body 1 is that Open Side Down
U-shaped, the upper end of described cylinder body 1 is provided with steam vent 10, be provided with steam vent 10 venting check valve 9.Top in cylinder body 1 is liquid
Pumping cavity 8, the two ends of described hydraulic fluid chamber 8 are provided with end cap 21, be provided with bearing 22, be provided with revolution between bearing 22 in end cap 21
Axle 7, the pars intermedia of described gyroaxis 7 is sprocket.The middle positioned at bottom in described cylinder body 1 is provided with dividing plate 19, dividing plate
19 centre is provided with oil input channel 20, and the lower end of oil input channel 20 is fuel feed hole 13, and the upper end of oil input channel 20 is located in hydraulic fluid chamber 8 simultaneously
It is provided with outage in upper end, at outage, be provided with repairing check valve 6.Cylinder body 1 bottom is divided into left cylinder by described dividing plate 19
16 and right cylinder body 2, described left cylinder 16 and right cylinder body 2 are two separate cylinder bodies, and left cylinder 16 and right cylinder body 2 is upper
Hydraulic fluid chamber 8 UNICOM is passed through at end.It is respectively equipped with left piston 18 and right piston 4, left piston 18 He in left cylinder 16 and right cylinder body 2
It is respectively equipped with left sealing ring 17 and right sealing ring 3 between right piston 4 and left cylinder 16 and right cylinder body 2 inwall.Left piston 18 and the right side
