Abstract
1371137 Suspension levelling systems FICHTEL & SACHS AG 17 March 1972 [20 March 1971] 12708/72 Heading B7D In a vehicle suspension levelling system comprising a pump 20 supplied by a reservoir 21, a level regulating valve 23 and shock absorbers 31 with associated hydropneumatic springs 30, a shut-off valve 22 connected to the pump 20 and reservoir 21 by pressure and discharge lines 25, 24 and to the level regulating valve 23 by supply and return lines 26, 27 prevents flow of fluid from or to the shock absorbers 31 through, the level regulating valve 23 when the pump is not operating. A spring-loaded valve 10 prevents reverse flow between tappings 1, 2 for the pressure and supply lines 24, 26 respectively; ‘and a second spring-loaded valve 8 is opened by a ball 6 acting through a thrust rod 7 to permit communication between tappings 3, 4 for the return and discharge lines 27, 25 respectively only when pressure fluid is delivered to the tapping 1. Connections 13 for leakage lines 28 from tne shock absorbers 31 communicate with the return/discharge side of the valve 22 through one-way valves 14. A relief valve 15 prevents excessive pressures in the pressure line 24.
