摘要： An oleopneumatic suspension with variable throttle orifices, particularly for aircraft landing gear comprising a rod (1) enclosing a pneumatic spring (2) and being fixed with respect to a piston (4) sliding in a cylinder (3), two valves (6) and (7) with permanent throttle orifices, the valve (6), which is of greater cross-section, throttling in the compression phase and the valve (7), which is of lesser cross-section, throttling in the extension phase, the suspension comprising in addition a throttle device, the section of whose orifice varies in dependence on the position and the direction of displacement of the piston (4) in the cylinder (3) so that over a given distance around a predetermined equilibrium position the orifices ensuring throttling in the compression and extension phases are of cross-sections respectively greater than the corresponding orifices over the remainder of the distance covered by the piston (4) in the cylinder (3). While primarily for use in connection with landing gear or support bogies of aircraft, the suspension is also suitable for land vehicles or for testing.

摘要： A hydraulic shock absorber including inner and outer tubes telescopically fitted together and an orifice variable in response to relative movement of the inner and outer tubes. A large diameter tubular holder is disposed coaxially around an upper portion of the outer tube to provide a space between the outer tube and the holder, the space being divided by a tubular partition membrane disposed coaxially in the space into a high-pressure gas chamber located outside of the membrane and a low-pressure gas chamber located inside of the membrane and communicating with an upper space within the outer tube. The shock absorber is of the hydraulically and pneumatically operated type, is simple in structure, and can be assembled with ease while maintaining a desired degree of performance. When the shock absorber is at the end of the extension stroke, there is a sufficient length of span between an outer tube sliding portion and an inner tube sliding portion between which the variable orifice is located so that even when the shock absorber is subjected to lateral bending forces, the orifice clearance is prevented from being varied or deformed, to ensure reliable and smooth operation of the shock absorber.

摘要： A shock absorber includes an outer cylinder and a slidable member fitted in the outer cylinder. The slidable member is inserted into the outer cylinder, and thereafter a beading technique is applied to the outer cylinder so as to form an annular bead on the inner peripheral surface of the outer cylinder for retaining the slidable member within the outer cylinder.

摘要： The shock absorber is of the type comprising a cylinder and piston containing hydraulic fluid and wherein the piston has fluid bypass holes so that fluid can pass from one side of the piston to the other within the cylinder. Tapered pins at one end of the cylinder are receivable in the fluid bypass holes when the piston approaches the one end. A cage assembly in the form of guide rods supports the pins and passes through guide bores in the piston so that the pins and piston rotate as a unit and the pins are always held in alignment with the fluid bypass holes.

摘要： A two-stage oleo-pneumatic shock absorber incorporating two pneumatic (air) pressure chambers, a high air pressure chamber and a low pressure (air) chamber, separated by a hydraulic fluid (oil) pressure chamber. The oil chamber contains an orifice and metering pin, which orifice and metering pin control the rate of collapse of the low pressure air chamber. It also contains a second orifice and metering pin which control the rate of collapse of the high pressure air chamber. Both metering pins are preprogrammed so as to interact with each other and effect a nearly constant load throughout the stroke of the shock absorber, even under transient loading conditions.

摘要： A damper system for a vehicle including a pressure tube and a piston assembly. A stroke dependent damper assembly is coupled to a piston rod at a position below the piston assembly. A free floating piston positioned in an internal cavity of the stroke dependent damper assembly is longitudinally moveable between retracted, middle, and extended positions. A metering pin extends from the floating piston into a through-bore in a distal end of the stroke dependent damper assembly. An orifice is defined between an inner surface of the through-bore and an outer surface of the metering pin. Longitudinal movement of the floating piston changes the position of the metering pin in the through-bore, which changes the size of the orifice. Fluid flow through the orifice is restricted when the orifice size decreases, which slows down the movement of the floating piston as it approaches the retracted and extended positions.
