Abstract

1364708 Power-assisted steering DAIMLER-BENZ AG 8 Nov 1971 [14 Nov 1970] 51812/71 Heading B7H A fluid pressure actuating cylinder in a powerassisted steering system for a vehicle includes valves 33, 34 arranged to open communication between chambers (15) (Fig. 1, not shown), 16 at opposite sides of a working piston (11), (Fig. 1), when the piston approaches either end position, one valve being actuated at one end of the piston stroke arid the other at the opposite end by a cam surface 55, 60, 56 formed on the steering arm shaft 14. Each valve opens into chamber 16 and includes a bush 40 or 41 with radial through bores 44 or 45 and a spring-loaded slide 38 or 39 having longitudinal peripheral grooves 42 or 43 and a control edge 48 or 49. The bases 44 or 45 communicate with annular cavities in each valve chamber 31 or 32, the cavities being interconnected by a conduit 30 which also connects with a chamber 25 of a control valve 20 in constant communication with chamber (15) of the actuating cylinder. The valves 33, 34 are circumferentially displaced relative to shaft 14 so that towards one end position of the piston (11) the portion 56 of the cam surface allows valve 34 to open and fluid passes from chamber 16 via grooves 43, bores 45, chamber 32 and chamber 25 to the other side of the piston. At the opposite end of the piston stroke valve 33 is actuated by cam portion 55. Means may be provided to prevent the shut-off slides being accidentally removed (Fig. 4, not shown).
