Utility model patent for a hydraulic device that adjusts the height of vehicles (assembly "A"), comprising an external cylinder (1), an internal channel (2), an internal thread (3) and an external thread (4), a threaded plate (5), a pressure inlet (6), an internal cylinder (7) with a projection (8) and thread at the end (9), compression channels (10), a central cylinder (11), a face closed by upper wall (12), an external channel (13), an internal projection (14), a through-hole (15), fixed packing (16), moveable packing (17), and when subjected to the pressure inlet (6) same moves the central cylinder (11) with the moveable packing (17), causing the central cylinder (11) to move to the interior of the cylinder (1), thereby suspending the vehicle at the required height. Assembly "B" is composed of an internal cylinder (1), an internal channel (2), an internal thread (3), a plate (4), a pressure inlet (5), an internal cylinder (6), an external thread (7), compression holes (8), a face channel (9), a central cylinder (10), an external projection (11), an internal notch (12), an external channel (13), an internal channel (14), a fixed O-ring (15), a moveable O-ring (16), moveable packing (17), moveable packing (18), a fixed O-ring (19), and when subjected to the pressure inlet (5) same moves the central cylinder (10) together with the moveable packing (18; 17 and 16) thereby pressing the central cylinder (10) out of the cylinders (1 and 6), thereby suspending the vehicle at the required height. |
