  • the casing 3 communicates with a sealed chamber 1 7 of volume V through an orifice 18 fitted with a valve 19 such as a blade valve.
  • the valve 19 opens to put the chamber 17 in communication with the rest of the casing when the pressure in the chamber 17 is lower than the pressure prevailing in the rest of the casing.

  • the exact location of the member 12 on the cylinder head 2 or the transfer channel 10, or the cylinder will be determined by the technician so that the quantity of fuel mixture escaping through the ports 7 before you burn it is zero or as low as possible.
  • a variant of the device consists in adding to the complete engine previously described on the tube 20 a short tube 23 opening into the open air or into an air filter through the orifice 24 or into a gas source such as, for example, a source fuel mixture.
  • the orifice is equipped with a valve 25 which can for example be a blade valve (FIG. 8).
  • the location 26 (whether in the case of FIG. 1 as well as in that of FIG. 8) of the connection of the tube 20 on the exhaust manifold 16 is judiciously chosen to obtain a sufficient wave effect
  • An example of such a device can be a butterfly 27 placed just after connection 26 in the pipe 16 - (Fig. 9) whose opening angle can be corrected according to the operating characteristics of the engine.
  • FIG. 9 Another example concerning the configuration of the pipe would be to give a form of convergent 26a (FIG. 9) to the pipe 20 at the connection 26 to the exhaust manifold, this convergent having a section which decreases going from the manifold d exhaust 16 to line 20.
  • a sealed chamber per cylinder this is the case in FIGS. 10, 11 and 12, or on the contrary common to different cylinders.
  • these sealed chambers 17, 17a, 17b and / or 17c may be supplied by the casing 3, 3a, 3b and / or 3c of the cylinder in which they inject the air, in the case of FIGS. 12 and possibly 1 or on the contrary by the casing of one of the other cylinders, in the case of FIGS. 10 and 11.
  • each tube 20 according to the invention corresponding to injection into a cylinder could in fact be connected - (communication 26) to the exhaust pipe 16 of the same cylinder, case of FIGS. 10, 11 and possibly 1, as well as that of a different cylinder, case of FIG. 12.
  • An example of a particular application could be, in the case of a multi-cylinder, to have the sealed chamber inflated by the casing of another cylinder and the exhaust communicating with the sealed chamber used for injection into its own cylinder.
  • a very short tube 20 may be sufficient since it is no longer essential for the positive wave to arrive after the opening of the transfer lights.
  • Figures 10 and 11 therefore show such applications to 2 and 3 cylinder engines.
  • the principle can be generalized to engines with a higher number of cylinders.
  • each cylinder has its individual sealed chamber supplied by its own casing and by a tube 20 coming from the exhaust of one of the other cylinders.
  • FIG. 13 represents the case of a chamber 17 ′ connected to two different pump casings 3 and 3a.
  • This chamber is extended by a pipe 17a 'up to a spraying member 12. Furthermore, this pipe is connected to an exhaust pipe 17a' by an auxiliary pipe 20.
  • the chamber 17 ′ can be connected to one or more spraying members.
