Abstract
A scavenger valve and method of directing gas in a two stroke engine are provided involving poppet elements in a scavenger valve with specific multiple, different flow paths from individual poppet heads.
Claims21
A method of directing intake gas in a multiple-poppet-element two-stroke_scavanger valve, the valve comprising a seat plate disposed opposite a guard plate, with at least one line of poppet elements having poppet heads, the poppet elements being mounted in the guard plate, the guard plate also having at least one exit port, the method comprising:
- receiving in the two-stroke scavenger valve a poppet opening pressure from the intake gas;
- and
- directing over ½ of gas particles flowing across at least one poppet head directly into the engine.
A device for directing intake gas in a multiple-poppet-element two-stroke engine scavenger valve, the device comprising:
- means for receiving in the two-stroke engine scavenger valve a poppet opening pressure from the intake gas;
- and
- means for directing over ½ of gas particles flowing across at least one poppet head directly into the engine.
A scavenger valve comprising:
- a scavenger valve_guard plate including:
- at least one line of poppet elements having substantially round poppet heads,
- at least one exit port having four poppet elements partially disposed in line with the exit port, wherein at least some of the gas flowing over the poppet head flows directly into the exit port without flowing over any part of the guard plate;
- wherein an angle of exposure of each of four poppet elements is more than 43 degrees;
- a scavenger valve_seat plate including a valve seat positioned and arranged to engage the poppet head.
A scavenger valve comprising:
- a scavenger valve guard plate including:
- at least one line of poppet elements having substantially round poppet heads;
- wherein at least some of the poppets have four exposed sections such that, for each exposed section:
- at least some of the gas flowing over the exposed section flows directly into an exit port located in said guard plate without flowing over any part of the guard plate and each of the four exposed sections is exposed to a different exit port than the other three exposed sections of any individual poppet head;
- a scavenger valve seat plate including a valve seat positioned and arranged to engage the poppet head.
