Abstract:
An aircraft landing gear shock absorbing strut having an outer cylinder and a sliding tube coupled within the cylinder bore to move between compressed and extended conditions. The cylinder and tube define a variable-volume internal chamber. The internal chamber is divided into a first spring chamber and a second spring chamber. The first spring chamber is a pneumatic chamber containing a first gas that is compressed when the strut moves from the extended condition to the compressed condition to provide compression damping. The second spring chamber contains a second gas and a hydraulic liquid, and is configured to compress the second gas when the strut moves from the extended condition to the compressed condition. The second spring chamber contains one or more damping orifices through which the oil passes as the strut extends to provide recoil damping during extension of the strut.

Claim (Index 5):
The aircraft landing gear shock absorbing strut according to  claim 1 , wherein the first spring chamber comprising a variable volume sub-chamber in fluid communication with a fixed volume sub-chamber via the flow restrictor, to provide compression damping to the shock absorbing strut as gas is forced into the fixed volume sub-chamber from the variable volume sub-chamber during compression of the shock absorbing strut.
