Abstract

1345668 Power-assisted steering mechanism GEMMER FRANCE 1 Sept 1972 40598/72 Heading B7H Power-assisted rack and pinion steering mechanism comprises a helical pinion 1 meshing with a rack having oblique teeth, a valve spool 14 rigidly connected to the pinion 1 coaxially thereof and slidable in a valve housing 7 having ports 8, 9a, 9b, 10a, 10b, 11 in its lateral walls, a reaction spring 13 the force of which is adjustable by an adjusting sleeve 17, and an adjusting rod 16 for setting the neutral position of the valve spool 14 in the housing 7. The reaction spring 13 is contained between pistons 11, 12 defining a hydraulic reaction chamber communicating with pressure supply port 8, the piston 11 abutting a shoulder on the spool 4 and the piston 12 abutting the sleeve 17 which is adjustably screwed into the spool. The adjusting rod 16 is screwed into a housing and cover 15 and carries a sleeve 14 abutting the piston 12.
