Abstract

VáLVULA DE CONTROLE, SISTEMA DE DIREçãO HIDRáULICA PARA GIRAR RODAS DIRIGìVEIS DE UM VEìCULO, E, MéTODO PARA OPERAR UMA VáLVULA DE CONTROLE EM UM SISTEMA DE DIREçãO DE POTêNCIA DE UM VEìCULO COM RODAS . Uma válvula de controle para um sistema de direção de potência hidráulica inclui um par de circuitos de fluxo dispostos em paralelo. Cada circuito de fluxo inclui um orifício a montante e um orifício a jusante dispostos série. Cada conjunto de orifícios define entre os orifícios uma zona de pressão intermediária da válvula. Ambos orifícios se fecham conjuntamente a partir de uma condição centralizada da válvula e se fecham completamente substancialmente conjuntamente em uma condição completamente fechada da válvula. O orifício a jusante é maior do que o orifício a montante quando abertos para minimizar a probabilidade de cavitação e ruído. Uma passagem de equalização fluidicamente conecta ambas zonas de pressão intermediárias para equalizar pressão a despeito de variações no tamanho de orifício em virtude de tolerâncias de fabricação. A válvula de controle inclui uma passagem de derivação em paralelo com os circuitos de fluxo. Uma válvula de alívio de pressão na válvula de controle tem um membro de válvula normalmente fechado na passagem de derivação que abre a válvula na eventualidade de sobrepressão.
