ABSTRACT:
A automatic fluid distributing valve timing device in combination with an internal combustion engine of which is adjustable and variable, a device controlling opening and closing degrees of the valves in relationship to the crankshaft of a common reciprocating engine. This device controls the opening of a valve by a pressurized oil co-ordinating disk working in conjunction with a actuating piston attached to the cylinder head of a high performance engine, of which when fed by oil pressure, opens intake and exhaust valves by the alignment of two elements allowing oil to flow for a regulated time and of which is adjustable, adjusting valve duration, overlap and lift. This device eliminates multiple working parts of the engines valve train such as the conventional cam, lifters, push rods and rocker arms, eliminating a large percent of friction and horsepower loss. The novel invention has very few working parts compared to the above mentioned valve train, resulting in a large horsepower increase. The device gives the proper valve duration, overlap and lift throughout the entire r.p.m. range automatically, while improving engine combustion, fuel economy and smog pollution emissions, such as carbon monoxide and hydrocarbons. This may be a new break through in the smog control problems, which will revolutionize the combustion engine.
