Definitions

  • the invention relates to a two-stroke oscillating piston engine with at least one reciprocating piston body and a corresponding number designed for the two-stroke function, with fresh gas inlet openings, fresh gas transition channels and exhaust gas outlet openings, the hollow cylinder being provided from parallel screwed-together parts, and wherein the piston body There is an operative connection with a crank mechanism, so that the radial force components on the piston body are kept as small as possible.
  • the task was to burn the fuel of the combustion gas as completely as possible in the expansion space of the engine.
  • Piston body has a cylindrical shaft, on which three cylindrical rings acting as pistons are attached, that the hollow cylinder surrounding the piston body is provided in its longitudinal center with a hollow cylinder piece symmetrical to it, the axial bore of which is divided into two fresh gas feed spaces by the central ring of the piston body , wherein this hollow cylinder piece symmetrically to its longitudinal center has the two fresh gas inlet openings arranged next to each other, and the feed spaces are connected at their outer ends by a transition groove to the corresponding fresh gas transition channel, that on both end faces of the middle hollow cylinder piece there is an identical intermediate wall with a continuous part of it belonging fresh gas transition channel is provided that two symmetrical working cylinder pieces are then installed on these two partitions, the axial bores through the
  • the two outer rings of the piston body are each divided into an inner combustion chamber and an outer fresh air feed chamber, that at least in the longitudinal center of these working cylinder pieces, two radial openings are arranged next to one another, the inner openings being provided as exhaust gas outlet openings and the outer
  • FIG. 1 shows a longitudinal section through the hollow cylinder
  • FIG. 2 is a view, in the direction of arrows II-II of FIG. 1, on the left piece of the cylinder when the end cover is lifted,
  • FIG. 3 shows a view, in the direction of arrows III-III of FIG. 1, onto the left intermediate wall
  • FIG. 4 shows a floor plan for FIG. 2
  • FIG. 5 shows a floor plan for FIG. 3.
  • the two-stroke oscillating piston engine shown has at least one reciprocating piston body 1, which is surrounded by a hollow cylinder 2 consisting of several parallel, coaxially screwed parts (FIG. 1).
  • the piston body 1 is operatively connected to a special crank mechanism (not shown in the drawing), the crank pin of which is mounted in a sliding pin which swings at right angles to the longitudinal axis of the piston body 1, the gear part receiving the sliding pin being firmly connected to the piston body 1.
  • the sliding pin should keep the radial force components on the piston body 1 as small as possible by bypassing the connecting rod.
  • the piston body 1 has a cylindrical shaft 3. On this are three cylindrical, like pistons we pending rings 4a, 4b, 4c pinned.
  • the hollow cylinder 2 is symmetrical with respect to its longitudinal center, as is the middle hollow cylinder piece 5.
  • the axial bore of this hollow cylinder piece 5 is divided by the middle ring 4b into two fresh gas feed spaces 6a, 6b.
  • Symmetrical to its longitudinal center, the hollow cylinder piece 5 has two fresh gas inlet openings 7a, 7b arranged side by side.
  • the outer ends of the feed spaces 6a, 6b of the hollow cylinder piece 5 are each connected by a transition groove 8a, 8b to a left or a right fresh gas transition channel 9a, 9b.
  • Radial openings 19, 20 are provided diametrically opposite the exhaust gas outlet openings 17b, 18a, which temporarily connect the fresh gas transition channels 9a, 9b to the combustion chambers 13, 14.
  • the deadline air feed spaces 15, 16 are connected to the fresh gas transition channels 9a, 9b by radial transition grooves 21, 22 (FIGS. 2, 4).
  • the two working cylinder pieces 11, 12 are each closed off in the axial direction by an outer wall 23, 24. With each piston movement to the left, the ignited gas mixture in the combustion chamber 13 expands between the left intermediate wall 10a and the left outer ring 4a.
  • Fresh air is then advanced through this left outer ring 4a and fresh gas through the middle ring 4b to expel the burned, expanded gas, while the outer right ring 4c compresses fresh gas with additional fresh air in the combustion chamber 14.
  • the piston moves to the right, the corresponding processes are repeated analogously.
  • the distance between the radial fresh air transition grooves 21, 22 and the radial transition openings 19, 20 is smaller than the distance between the radial fresh gas transition grooves 8a, 8b and the radial transition openings 19, 20.
  • the addition of fresh air results in a more complete combustion of the fuel in the combustion chamber.
  • a plurality of hollow cylinders 2 and piston bodies 1 can be provided to compensate for the torque.

Abstract

Ce moteur comprend des troncons de cylindre (11, 12) pourvus de chambres d'avance (15, 16) pour l'air frais supplementaire. Les deux anneaux exterieurs (4a, 4c) agissant comme pistons, aspirent de l'air frais a travers les ouvertures d'admission (17a, 18b) et l'obligent d'entrer dans les chambres de combustion (13, 14) a travers les conduits de communication (9a, 9b) et les ouvertures (19, 20). L'anneau median (4b) sert a l'alimentation en gaz frais des chambres de combustion (13, 14). Les rainures radiales (21, 22) pour l'air frais se trouvent a une petite distance des ouvertures (19, 20) que les rainures radiales (8a, 8b) pour le gaz frais. Le gaz brule et detendu est d'abord expulse des chambres de combustion (13, 14) par le gaz frais; ensuite, les chambres de combustion (13, 14) sont remplies de gaz frais et d'air frais. Ainsi, on evite d'expulser du gaz non brule avec du gaz brule et on obtient une combustion amelioree dans les chambres de combustion (13, 14).
