Abstract : The patent describes a pressurized air-oil, telescopically configured, shock absorber of the type that may be incorporated in an aircraft landing gear or other devices subject to high structural stresses caused by high impact loadings. It consists of a substantially conventional shock absorber modified to include a control valve assembly which programs the opening and closing of the piston position controlling metering orifice thereof by means of a unique valve sleeve normally spring-urged toward a closed metering orifice condition but positioned to effect the opening thereof in proportion with the magnitude of the acceleration to which it is exposed during the impact loading of the aforesaid landing gear or other devices.
