Abstract

A travel limiting device for hydraulic power steering is constituted by two valve members (31, 35, 36, 37) which are inserted in respective exhaust ducts (21, 22, 23, 24, 25) for fluid under pressure, and are housed in the wall (18) of the power steering cylinder (1) beside a sector gear (4) which drives the steering shaft. These valve members (31, 35, 36, 37) are actuated by respective operating rods (41) with free ends (44) which project into the cylinder (1) in positions such that one is engaged by a respective side (52, 53) of the sector gear (4) in each of the end of travel positions of the maximum allowed steering.
