Abstract

ponte de válvula compreendendo câmaras côncavas. uma ponte de válvula compreende um corpo central e uma pelo menos primeira e segunda porções de interface de válvula estendendo-se a partir do corpo central, sendo que cada uma dentre a pelo menos primeira e a segunda porções de interface de válvula define uma câmara configurada para receber uma válvula de motor e a mola de válvula e retentor de mola correspondentes. cada câmara compreende uma superfície de controle de ponte de válvula configurada para entrar seletivamente em contato com pelo menos um dentre a mola de válvula e o retentor de mola correspondentes, sendo que cada superfície de controle de ponte de válvula é uma superfície côncava configurada para se estender para baixo em torno da mola de válvula correspondente.valve bridge comprising concave chambers. a valve bridge comprises a central body and at least first and second valve interface portions extending from the central body, each of the at least first and second valve interface portions defining a chamber configured to receive an engine valve and corresponding valve spring and spring retainer. each chamber comprises a valve bridge control surface configured to selectively contact at least one of the corresponding valve spring and spring retainer, each valve bridge control surface being a concave surface configured to intersect. extend downward around the corresponding valve spring.
