Abstract
"CONJUNTO DE TREM DE VáLVULAS, MOTOR DE COMBUSTãO INTERNA E MéTODO PARA MONTAR UM MOTOR DE COMBUSTãO INTERNA". Um conjunto de trem de válvulas para um motor de combustão interna compreende um portador comum que suporta os braços oscilantes do motor por meio de pontos de apoio individuais cada um dos quais preferivelmente forma parte de um ajustador de folga hidráulico. Cada braço oscilante é construído deformando uma chapa fina de metal na forma de um canal, a deformação também formando uma superfície parcialmente esférica para combinar com uma superfície do ponto de apoio. Os braços oscilantes podem ser montados por encaixe no ponto de apoio por meio de uma chapa fina resiliente, com abertura.
