  • Double effect distribution sequential valve shaft assembly
    Patent number: 5417188
    Abstract: A double-effect distribution sequential valve shaft assembly for use within a cylinder head cover of internal combustion engines or other valve-type distribution systems, includes a rotating valve shaft with openings from side to side in the vertical plane and a jacket supporting the valve shaft for rotation therein. An opening in the valve shaft communicates through diametrically opposed openings in the jacket with the combustion chamber twice during every turn of the valve shaft to regulate the flow of gases into and out of the combustion chamber. The jacket is provided with a series of labyrinths etched into an inner surface thereof to create a barrier to gases flowing out of the combustion chamber during the compression and explosion strokes. The jacket is also provided with a plurality of circumferential grooves formed in the inner surface thereof to form a high pressure fluid seal when lubricating oil is introduced therein under pressure.

  • Automatic variator valve overlap or timing and valve section
    Patent number: 5355849
    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 or timing and the valve opening section or to operate a double overhead camshaft with poppet valves for the purpose of regulating valve overlap or timing while the engine is running. A motor reducer advances a spindle against the valve shaft with a grooved screw at one end of the same, causing the shaft to turn and move, thereby varying the valve overlap or the valve section and valve overlap.
