ABSTRACT:
An automatic variator for use in an internal combustion engine and other engines which use valve-type distribution systems, to operate a twin set of double-effect distribution sequential valve shafts for the purpose of regulating the valve overlap and the valve opening section while the engine is running. A motor reducer advances a spindle against the valve shaft with a grooved screw at one end of same, causing the shaft to turn and move, thereby varying the valve overlap and the valve section.
