Abstract

método de lubrificação de lóbulo de eixo de cames de freio motor. a presente invenção refere-se a um sistema de frenagem de motor do tipo em que um lóbulo de carne suspende um seguidor pelo contato direto, onde o seguidor é pelo menos parcialmente contido em um alojamento de freio contendo óleo. um pistão escravo é também pelo menos parcialmente contido no alojamento de freio e, durante a frenagem do motor, o movimento do seguidor faz com que o óleo mova o pistão escravo para fora. o movimento do pistão escravo abre uma válvula de escape de frenagem de motor para abrir um percuso de fluxo entre um cilindro do motor e um conduto de escape. uma passagem de óleo através do seguidor é provida para lubrificar uma interface entre uma face chata do seguidor e o lóbulo de carne com óleo do alojamento de freio. a passagem de óleo apresenta um orificio de saída que é aberto na face chata fora da área de contato entre a face chata e o lóbulo de carne.engine brake camshaft lobe lubrication method. The present invention relates to an engine braking system of the type wherein a meat lobe suspends a follower by direct contact, where the follower is at least partially contained in an oil-containing brake housing. a slave piston is also at least partially contained in the brake housing and, during engine braking, movement of the follower causes the oil to move the slave piston outward. movement of the slave piston opens an engine braking relief valve to open a flow path between an engine cylinder and an exhaust duct. an oil passage through the follower is provided to lubricate an interface between a flat follower face and the oil lob of the brake housing. The oil passage has an outlet port that is open on the flat face outside the contact area between the flat face and the meat lobe.
