Abstract
A rocker arm lubrication arrangement for an engine includes a shaft which pivotally mounts a number of rocker arms. The shaft has a longitudinally extending lubricant supply bore and radially upwardly extending supply bores corresponding to positions of the rocker arms. Lubricant passes along the longitudinally extending supply bore to the radially extending bores and then exits via corresponding bores in the rocker arms. The lubricant is under pressure and thus exits as jets of lubricant which impinge on an underside of an engine cover to be returned as a lubricant spray. The rocker arms may be arranged on the shaft such that the jets are intermittent.
