Abstract
"APARELHO". Uma válvula de regulagem de fluido hidráulico (18) de uma caixa de direção servo-assistida (10) inclui primeiro e segundo membros de válvula relativamente giráveis (60,62) que direcionam fluido hidráulico para fluir entre os membros de válvula (60,62) de orifícios de entrada (70) para orifícios de saída (92). Os membros de válvula (60,62) possuem estrias radialmente ospotas (71-79, 101-109) e ranhuras (81-89, 121-129) definindo orifícios (130) que aumentam e orifícios (130) que se restringem pela rotação relativa dos membros de válvula (60,62)a partir de posições neutras. Um par de orifícios restritores (130b, 130c) são localizados em paralelo entre orifícios de entrada (90) e orifícios de saída (92). Cada um desses orifícios restritores paralelos (130b, 130c) é definido por uma porção correspondente de canto chanfrado de uma estria correspondente (101, 102). Os membros de válvula (60,62) provêem contrapressão em orifícios selecionados entre os orifícios de saída (92)e os orifícios de entrada (90). Os orifícios selecionados, nos quais a contrapressão é provida, incluem apenas um (130c) dos pares de orifícios restritores paralelos (130b, 130c).
