Abstract

SISTEMA DE PONTE DE VÁLVULA PARA RESISTIR AO MOVIMENTO NÃO CONTROLADO DA PONTE DE VÁLVULA. Trata-se de um sistema de ponte de válvula que compreende um corpo de ponte de válvula configurado para se estender entre pelo menos duas válvulas de motor de um motor de combustão interna. O corpo de ponte de válvula compreende um orifício passante configurado para se alinhar com uma primeira válvula de motor e para receber um pino de ponte. Uma saliência de pino de ponte tem o orifício pas-sante formado na mesma, tem um comprimento longitudinal e termina em uma su-perfície superior. O comprimento longitudinal é configurado de modo que a superfí-cie superior do pino de ponte entre em contato com uma superfície do braço de ba-lancim auxiliar para resistir ao movimento descontrolado da ponte de válvula quan-do a ponte de válvula está em um estado descontrolado em relação às pelo menos duas válvulas de motor.VALVE BRIDGE SYSTEM TO RESIST UNCONTROLLED MOVEMENT OF THE VALVE BRIDGE. A valve bridge system comprises a valve bridge body configured to extend between at least two engine valves of an internal combustion engine. The valve bridge body comprises a through hole configured to mate with a first engine valve and to receive a bridge pin. A bridge pin boss has the through hole formed therein, has a longitudinal length and terminates in an upper surface. The longitudinal length is configured so that the upper surface of the bridge pin contacts a surface of the auxiliary rocker arm to resist uncontrolled movement of the valve bridge when the valve bridge is in a state. out of control with respect to at least two engine valves.
