Abstract

1444631 Power-assisted steering ADWEST ENG Ltd 4 Sept 1974 [4 Sept 1973] 41571/73 Heading B7H A power-assisted rack-and-pinion steering mechanism comprises a rack bar 2 on which is secured a piston 9 having passages 16, 17 each communicating via a ball valve 18, 19 with an annular groove 15 or with a respective recess. When the piston is moved fully to the left pressure fluid flows, via passage 16, valve 18, an opening 20 in the cylinder, an annular passage 21 and port 12, to the left side of the piston to equalize pressure on its two sides. Similarly when the piston is moved fully to the right pressure fluid flows, via passage 17, valve 19, opening 22, elbow 23 and port 11, to the right side of the piston to equalize pressure on the two sides of the piston. (For Figures see next page.)
