Abstract

Patente de Invenção: <B>"ELEMENTO DE AMORTECEDOR PARA UM SISTEMA DE ALIMENTAçãO DE COMBUSTìVEL"<D>. A presente invenção refere-se a um elemento de amortecedor para amortecer vibrações de pressão num circuito de combustível de um motor de combustão interna com injeção de combustível. O circuito de combustível possui um distribuidor de combustível (2), a partir do qual válvulas de injeção são alimentadas com combustível através de assentos de válvulas (3). O elemento de amortecedor possui um corpo de tubo flexível (1) disposto no distribuidor de combustível (2), que separa de modo vedante uma câmara de combustível interna (1a) através da qual flui o combustível, de uma câmara de combustível externa (2a) através da qual flui o combustível, conectada com os assentos de válvulas (3), e cuja parede consiste em um material elástico. O elemento de amortecedor segundo a presente invenção pode ser usado em sistemas de alimentação de combustível com ou sem refluxo.
