Definitions

  • the present invention substantially relates to an improved motor, in the first instance to a two-stroke motor whereby the working process is accomplished in two strokes or in one revolution of the crank-shaft, which does not exclude that the invention may be applicable to a four-stroke motor.
  • the generally current motor construction with ports is very simple and very reliable, a motor of this kind however has a comparatively low efficiency, which is mainly due to the fact that a very great quantity of fresh gases escapes via the exhaust during the scavenging stage, which one must accept due to the fact that due to the construction itself of the motor, a regulation between exhaust and scavenging ports is not possible, due to the fixed position of the ports the one in relation to the other.
  • the present invention relates to a two-stroke motor whereby the time during which the scavenging port is open and the exhaust time can be suitably regulated the one in relation to the other, independently from the position of the piston, and whereby this motor is extremely well adapted to rotate at a high number of revolutions, as, for instance, is the case of competition motors.
  • the motor according to the invention mainly consists in that in the combustion chamber of the motor there is at least one valve "running around” in this chamber.
  • the two-stroke motor substantially consists of a crank-case 1; a cylinder 2 and a cylinder-head 3, which in this case, for the sake of simplicity, are drawn as if they were made from one piece.
  • an intake port 4 is provided for; a connection between the crank-case 1 and cylinder 2, which runs into the cylinder 2 by means of an opening 6; an exhaust port 7 and a hole 8 for fitting the sparking-plug 9.
  • the motor is provided furthermore with a crank rod 11 fixed on the crank-shaft 10, with which crank rod 11, by means of a shaft 12, the connecting rod 13 is connected, which itself is assembled to the piston 15, so as to be able to oscillate, by means of a piston pin 14.
  • the cylinder-head 3 is internally made concave and hemispherical, whereby in this half spherical cavity a valve, in this case in the shape of a spherical segment 16 is provided for, which can free the exhaust 7, on the one hand, and the hole 8 for the sparking-plug 9, on the other hand, whereby this spherical segment 16 is connected with a rod 17 which is fixed in an appropriate way in a driving disc 18 which is mounted and guided in the cylinder-head 3 in such a way that it turns around an axis A-A and whereby in the disc 18 the rod 17 is fixed under a well determined angle.
  • the rod 17 shall be fitted in such a way that the spherical segment "runs around” in the combustion chamber, in other words that the shaft 17 is freely rotatably mounted in the plate 18. If necessary, on the shaft 17 a pinion can be provided for which meshes with a crown-wheel which is fixed in relation to the motor housing, whereby any stoppage of the spherical segment 16 in relation to the disc 18 is excluded.
  • the functioning of the motor according to the invention is very simple.
  • valve or spherical segment 16 is replaced by a valve in the shape of a disc 19 oscillating to and fro, whilst in figure 5 this valve 16 is replaced by a rotating cylindrical body 20 with an inclined basis face 21.
  • the motor can be adapted for driving with this fuel.
  • auxiliary and main valves could be provided for, which would be located adjacent to the sparking-plugs and through which a part of the exhaust gases would be expelled.
  • these valves may function as an auxiliary gas exhaust, whereby exhaust 7 the main exhaust remains, or as a main exhaust, whereby the exhaust 7 functions as an auxiliary exhaust.
