Abstract

AMORTECEDOR DE SUSPENSÃO DE VEÍCULO COM VÁLVULA INTEGRAL DE NIVELAMENTO DE ALTURA. A presente invenção refere-se a uma montagem de amortecedor de suspensão de mola pneumática que inclui um primeiro alojamento e um segundo alojamento que se move em movimento de telescópio em relação um ao outro. Um membro de acionamento, tal como um cabo, é conectado com uma válvula de nivelamento de altura em um dos alojamentos e é ligado com o outro alojamento. O membro de acionamento move um membro, tal como um came rotativo, um chapa de válvula rotativa e / ou uma válvula rotativa, de modo que alterações na altura da suspensão giram o membro. A rotação do membro seletivamente abre os caminhos de fluxo de admissão e de escape para controlar a pressão do ar na montagem de amortecedor e para manter a altura da suspensão pneumática em uma altura predeterminada.
