Hydraulic valve control system for internal combustion engines
This patent describes a hydraulic engine valve actuating assembly for use in an internal combustion engine cylinder head having a poppet valve which is axially shiftable therein by a rotary camshaft, the hydraulic engine valve actuating assembly. It comprises a housing having a mounted surface to attach to the cylinder head immediately above the poppet valve, a master piston cooperating with the camshaft and sealingly engaging the first cavity; a slave piston cooperating with the poppet valve and sealingly engaging the housing second cavity; a hydraulic energy and fluid storage accumulator assembly affixed and sealingly engaged relative to the housing and being provided with a fluid port coupled with the housing fluid passageway; valve means; the housing including a third cavity coaxially aligned with the poppet valve; and the valve means including a reciprocal valve piston sealingly engaged within the third cavity.
