Abstract

1,000,398. Hydraulic shock absorbers; valves. GIRLING Ltd. May 26, 1964 [May 27, 1963], No. 18335/63. Headings F2S and F2V. A valve in a shock-absorber comprises a resilient washer 11 which in its unstressed or free state is frusto-conical and which, when mounted in the valve is pre-stressed so that it is substantially flat. The washer 11 is confined between concentric annular seatings 12, 13 which are axially spaced by a distance substantially equal to the thickness of the washer. One or more radial grooves 21 may be formed in the outer seat 12.
