Abstract

1389523 Adjustable hydraulic dampers HANS BAUMGARTNER & CO 29 May 1973 [2 June 1972] 25581/73 Heading F2S The tube-within-a-tube hydraulic damper of 1,012,255 is provided, in the annular chamber 14 between the tubes 1<SP>1</SP>, 2, with at least one member 16, 16<SP>1</SP> whose position can be adjusted externally of the damper by screws 17, 18 to vary the effective size of the spaced parts 5 in the inner tube 1<SP>1</SP>. Liquid flows from the chambers 8, 9 on either side of the piston 7 to the annular chamber 14 and a reservoir 15 via the spaced ports 5; and back via non-return valves 10, 11.
