Abstract

1,006,265. Hydraulic shock absorbers. ARMSTRONG PATENTS CO. Ltd. Oct. 14, 1963 [Nov. 24, 1962], No. 44533/62. Heading F2S. A telescopic hydraulic shock absorber in which a piston 16 is provided with an hydraulic damping valve assembly 52, 56 and a foot valve assembly 28 communicates with a reservoir 14 is formed in one of the valve assemblies with an adjustable by-pass conduit (Fig. 2). The setting of the by-pass conduit is effected by an electrically operated stepping mechanism which includes a driver member displaceable in discrete steps from one position to another position by a switch means which energizes the electrical circuit. In the construction shown in Fig. 2 a driven shaft 60 of the stepping mechanism is provided with a longitudinal bore 62 which communicates with a transverse bore 64. The inner part 30 of the foot valve assembly 28 is formed with a plurality of circularly spaced, radial ports 66 of successively different diameter such that on the displacement of the driven shaft 60, the transverse bore 64 is brought into alignment with each of the ports 66 in turn. The shaft 62 may be introduced transversely into the shock absorber (Fig. 3, not shown). In a modification (Fig. 4, not shown) the driven shaft is housed concentrically within the piston rod, a bore in the piston communicating with the longitudinal bore in the end of the driven shaft 60. The stepping mechanism includes a solenoid actuated pawl and ratchet means (Figs. 5, 6, not shown) and the switching means is described with reference to Fig. 7 (not shown). Reference has been directed by the Comptroller to Specification 942,328.
