Abstract

"DISPOSITIVO PARA O ACIONAMENTO VARIáVEL DAS VáLVULAS DE TROCA DE GáS DE MOTORES DE COMBUSTãO INTERNA". A presente invenção refere-se a um dispositivo para o acionamento variável de válvulas de troca de gás para motores de combustão interna, em caso do qual um came continuamente rotante aciona um elemento intermediário, o qual executa um puro movimento rotativo, oscilante, e que, através de um came de comando, movimenta um elemento movido de acordo com a respectiva curva do curso da válvula. Para a alteração da curva do curso da válvula, a posição do eixo de giro do elemento intermediário pode ser mudada ao longo de uma curva de regulagem. O eixo de giro do elemento intermediário está formado por um pino, o qual da parte de seu guiamento pode ser girado livremente e que suporta discos de came conectados de maneira resistente à torção, os quais predeterminam de maneira direta ou indireta, a posição cada vez exigida sobre a curva de regulagem. O pino é girado através de um elemento de conexão apropriado.
