Abstract
A combined oil filtration and metering assembly for filtering and metering oil in an oil gallery, such as in a Lifter Oil Manifold Assembly of an internal combustion engine. The filtration and metering assembly includes a filtration element at an oil entrance leading to an internal chamber having a metering orifice as an outlet to a downstream portion of the oil gallery. Preferably the metering orifice has a diverging exit cone. Preferably, the assembly replaces directly a prior art metering valve in a LOMA socket without requiring retooling of the LOMA top plate. The assembly may be readily formed by molding of the filtration element into the oil entrance in an injection overmolding process.
