DISTRIBUTOR OF STEERING HYDRAULIC BOOSTER Russian patent published in 1998 - IPC

FIELD: transport engineering; steering hydraulic systems. SUBSTANCE: proposed distributor is provided with seat installed in pressure relief valve which connects reactive chambers with pressure space and is made movable relative to housing, thus forming variable-displacement chamber and providing connection of chamber with working medium pressure source. proposed distributor provides changing of force on steering wheel depending on resistance to turning of steerable wheels. EFFECT: improved safety owing to proportional change of force on steering wheel depending on resistance to steerable wheel turning. 3 dwg
