  • inventions with rotary pistons can be used in internal combustion engines, primarily gas IC engines, whereby valves would be opened, at a certain position of pistons, at the input (connecting) sides of the piston housings and therewith mixture of air and fuel would be brought into a certain space of the piston chamber under a certain and for that function sufficient pressure and then immediately upon closing the valve, the spark plug would spark the mixture or in any other therefore appropriate, all this repeats during each revolving (cycle). Determination of the moment of the opening and closing the valve and the moment when the mixture is sparked would be electronically or mechanically carried out, or in any other thereto appropriate way.

  • This device can have (working) protrusions, of any of the mentioned shapes; A; B; C; D; E or F and according to these the choice of the auxiliary shaped recesses G or H is made.
  • FIGS. 129 to 137 represents a device with a pair of gears, one single-sided working rotary piston A (single-sided working rotary piston A consists of a body 6 with a hole for the shaft in the centre and one (working) protrusion A) and one single-sided auxiliary rotary piston G (single-sided auxiliary rotary piston G consists of the body 6 with a hole for the shaft in the centre and one (auxiliary) protrusion G) and is best used with internal combustion engines, it consists from the piston housing 11 with inlet-outlet connections 20 , then the gear housing 9 , the separating wall 7 , the front cover 12 and the rear cover 1 , that are each to other coupled by bolts 16 that go through the appropriate holes 16 x and are screwed in the body of the rear cover 1 , and the piston housing 11 there is set one-sided working rotary piston A and one single-sided auxiliary rotary piston G that over the shafts 4 and 5 are firmly connected to the gears 10 in
  • the external shape of the device can be round, elliptic . . . etc. device can be used a part of a motor i.e. wherever there is a need to use it.
  • Inlet-outlet connections 20 can be in the piston housing 11 or at the rear cover 1 of that housing or combined where the inlet is in the housing and outlet in the cover and vice versa.
  • Length (thickness) of the pistons and the length of the housing can be increased or decreased (proportionally), all the single-sided pistons can be balanced in all the known and thereto appropriate modes, to prevent them to bring about vibrations in the working process. Sealing of the contact surfaces between the elements of the assembly can be achieved in all existing and thereto suitable modes.
  • This device can be with working protrusions of any of the mentioned shapes; A; B; C; D; E or F and according to which the choice of the (auxiliary) shaped recesses G or H, is made.
  • This type of the device can be used as a compressor, a pump, a vacuum apparatus, and therein can be, instead of one working and one auxiliary; double-sided working and double-sided auxiliary, or three-sided working and thee-sided auxiliary, or four-sided working and four-sided auxiliary rotary pistons.
