Abstract

Patente de Invenção: <B>"ORIFìCIO DE SANGRIA VARIáVEL COM DISCO PROVIDO DE ORIFìCIO". Um amortecedor de choque inclui um conjunto de válvula com um circuito de fluxo de óleo de baixa velocidade e um circuito de fluxo de óleo de velocidade média/elevada. Ambos os circuitos controlam o fluxo de fluido através do conjunto de válvula na mesma direção. O circuito de fluxo de óleo de baixa velocidade é regulado para prover um amortecimento de baixa velocidade para melhorar tanto o controle, quanto o manuseio do veículo. A regulagem do circuito de fluxo de óleo de baixa velocidade é feita dimensionando-se uma passagem restrita que é parte de um circuito e controla a pressão na qual o circuito de fluxo de óleo de baixa velocidade se abre. O conjunto de válvula da presente invenção pode ser localizado dentro ou de um conjunto de válvula de base, ou de um conjunto de válvula de pistão.
