Abstract
1,046,678. Hydraulic shock absorbers. STAHLWERKE BURNINGHAUS G.m.b.H. Oct. 1, 1964 [Oct. 2, 1963], No. 39990/64. Heading F2S. An hydraulic shock absorber comprises a main cylinder 4 having working therein a piston 2 and piston rod 20 assembly. The main cylinder 4 is housed coaxially within and slidable relative to a subsidiary cylinder 3, the main cylinder being provided between its ends with an annular, enlarged part 4 which divides the annular space between the main cylinder and the subsidiary cylinder with first and second channels 17, 15. The channels communicate with the main cylinder space 5 through ports 35 in the wall of the main cylinder, the first channel 17 also communicating with an oil chamber 26 and the second channel 15 with a first working chamber 6. The piston 2 divides the main cylinder space 5 into a main working chamber and a second working chamber 33 which are connected through a valved passage 13, 14 in the piston, the second working chamber also communicating with the first working chamber 6 through ports 34. The main working chamber is also connected to the oil chamber 26 through a one-way valve assembly 7 which is surrounded by a resilient ring 25 which limits the stroke of the piston. The oil chamber is formed by a flexible bellows 8 which may be connected to a further reservoir (Fig. 7, not shown) or it may comprise a rigid pressure-tight reservoir which may also be connected to a further reservoir (Figs. 8, 9, not shown). The subsidiary cylinder and the piston rod are each provided with a cup 10, 11 between which a spring is received. The shock absorber, Fig. 2 (not shown) is in its position for a normal load but if the load is increased the piston moves upwardly past the ports 35 and thus fluid passes, under pressure into the second working chamber 33 through the ball valve 16 and then into the first working chamber 6 to increase the length of the shock absorber. While the ports 35 are covered a pumping action takes place through the valves 7, 16 to increase the length of the first working chamber and also to force the piston outwardly in the main cylinder until the ports 35 communicating with the second channel 15 are uncovered whence pressurized fluid passes back to the reservoir from the first and second working chambers until these ports 35 are covered again (Figs. 3, 4, 5, not shown). The ratio of the areas of the outer end of the main cylinder and the inner end of the subsidiary cylinder may be such as to give a linear spring effect. The damper is connected to two relatively movable parts of a vehicle by rubber pads 23, pins 27 and nuts 24.
