Title: Improvements in or relating to shock absorbing suspension devices for vehicles
IPC: F16F9/06
Filed: 1941-09-08
Abstract: 550,896. Oleo-pneumatic shock absorber. RIBBESFORD CO., Ltd., and THORNHILL, P. W. Sept. 8, 1941, No. 11470. (Class 108 (iii)] In apparatus for vehicles, aircraft and like purposes of the kind in which a variable working space filled with damping liquid communicates through damping valves with a chamber in which the liquid is kept resiliently under pressure by compressed air, the damping valve comprises two discs or flanged members moved relatively within a passage by a control piston in the air space. Within and without cylinder 10 works a cylindrical plunger 14 and a shrouding cylinder 16, the plunger 14 having a piston head 20 with an opening of about half its area accommodating the damping valve which consists of two disc-like members 27, 28, fitting the opening closely. The two discs are forced aprt by springs into contact with a nut 32 and a guiding spider 26 carried by a rod 24 connected to the control piston 25. The movement of the valves and rod is limited by the closure for the plunger 14 and the shoulder 22 on the piston head. Each disc member is formed with a separate relatively movable part 30 forced apart by a separate spring. Under normal loading, the valve discs are in the position shown with compressed air filling the space above control piston 25, and both liquid and compressed air filling the space between the piston head 20 and control piston. When the vehicle &c. goes over a bump, the shock absorber shortens, liquid passes freely from below to above the piston head 20, and the air is further compressed both above and below control piston 25. During this movement, the lower disc 28 is moved upwards by liquid pressure into contact with upper disc 27 and both are moved upward by the control piston. During rebound, the valves prevent flow of liquid downwards until the pressure below the piston head 20 is substantially less than that above it, this effect being due to the difference of area between the control piston and the valve. Extension of the shock absorber also occurs freely but return to the normal position is similarly retarded. In a modification, valve discs made in one part only are employed and the plunger is connected to the shrouding cylinder by a rubber element. The two elements of the shock absorber may be connected to overlapping tension members which reverse the direction of the applied forces.
