ABSTRACT:
A new and useful two-way valve with an adjustable aperture, to work in combination with a hydraulic valve lifter in a combustion engine, and particularly that of a high performance engine, preventing valve overlap and shortening cam duration at low operating speeds. The two-way valve having an adjustable aperture restricted oil bleed passage way, leading to the pressure chamber allowing the lifter to bleed down, whereby the engine runs and operates at its perfected capabilities at low and high speeds. The passage way being adjustable for many cam profile characteristics, adjusted narrow enough allowing it not to bleed at a higher revolution per minute, consequently causing lifter pump up to a fully solid condition at higher engine speeds, and substantially incorporate an effective solid lifter action, but without pumping beyond its predetermined point of stability eliminating valve float which causes engine misfire. Due to these characteristics the engine runs more efficiently improving gas economy, burning the gases more thorough helps eliminate smog pollutant emissions.
