Landing gear mechanism includes a variable area orifice to obtain the desired rebound damping of the landing gear mechanism during landing, and one or more check valve assemblies that operate in conjunction with the variable area orifice to provide the desired controlled instroke of the landing gear mechanism during landing. Also, the landing gear mechanism is provided with a relief valve assembly that permits bypass flow at a pre-set pressure drop only during an intermediate portion of the instroke of the landing gear mechanism to attenuate severe bumps and the like without adversely affecting the controlled instroke and rebound damping of the landing gear mechanism during landing.
