摘要

The revolving cylinder has two end flanges (1,2) which are separated by the cylinder (4). The cylinder wall has an inlet and outlet opening (5,6) for the hydraulic fluid connected through a selector valve. The cylinder houses the splined piston (11) which engages the teeth (10) in the cylinder (16) and on the jack (3). A second piston (20) is spring loaded by the spring (23) and fits the end of the shaft (3). The oil passage (22) in the shaft connects both sides of the cylinder.
