SHOCK ABSORBER FOR AN AIRCRAFT LANDING TRAIN, AND, LANDING TRAIN

摘要

shock absorber for an aircraft landing gear, and landing gear. the invention relates to a shock absorber for an aircraft landing gear, the shock absorber including a main cylinder (1) on which a rod (2) is mounted to slide telescopically, the shock absorber having one or more pneumatic chambers (12, 22) filled with gas, a supply of hydraulic fluid (5), and a choke (14, 24) to strangle the hydraulic fluid such that when the shock absorber is shortened, the gas in the pneumatic chambers is compressed and the hydraulic fluid is strangled, in which the pneumatic chambers are completely contained in one or more auxiliary cylinders (10, 20) external to the main cylinder, and in each of which a sealed piston (11, 12) is mounted so slide to separate a pneumatic chamber (12, 22) contained in said external auxiliary cylinder from a fluid chamber (13, 23) in fluid flow communication with the main cylinder. according to the invention, throttling means (14, 24) is arranged at the entrance of a fluid flow connection between the main cylinder (1) and the auxiliary cylinders (10, 20).
