Definitions

  • the invention relates to a power and work machine with displacement.
  • the best known are motors and compressors based on the Wankel principle, which has the disadvantage that the three edges of the rotary piston separating the individual working chambers are very narrow. This causes major leakage problems because, in contrast to the reciprocating piston engine, several seals cannot be arranged one behind the other on the narrow edge. A seal is particularly difficult in the outer corners of the combustion chamber to be sealed. Furthermore, the piston does not rotate around a fixed center of rotation, which has a negative effect on the space requirement and smooth running.
  • the invention is therefore based on the object to provide a power and driven machine with displacement effect, with simplified sealing of the individual working chambers, improved smoothness and a more favorable mass-performance ratio.
  • This object is achieved by two concentrically mounted, common working chambers creating rotary pistons with a fixed center of rotation, the two pistons having separate, concentrically arranged shaft outlets, which are coupled via a gear with periodically changing rotary movements so that the two nested rotary pistons are rotated during rotation perform a relative movement from and to each other.
  • the arrangement has the advantage that the two pistons have a common center of rotation, that all moving mass points are at a constant distance from this center and that there is complete rotational symmetry.
  • a further advantage is that it can always be ensured by a suitable arrangement of the inlet and outlet channels that a simultaneous access of the inlet and outlet channels to a working chamber is never possible.
  • a mostly water-cooled housing 1 the interior of which has the shape of a flat cylinder, two nested rotary pistons 2 and 3 rotate about a fixed center of rotation, which corresponds to the imaginary axis 4.
  • the shape of the two pistons 2 and 3 corresponds essentially to a flat base cylinder, each with two firmly connected, axially symmetrical opposite piston segments 18, the so-called outer piston 2 being hollow within its “base circle” and the so-called inner piston 3 being so narrow within its “base circle” is that it is rotatably arranged in the outer bulb 2.
  • the "piston segments" 18 of the inner piston 3 are located between the recesses in the piston segments 19 and 22 of the outer piston 2, the recesses being dimensioned so large that the inner piston 3 has a limited rotational movement about the imaginary axis 4 common to the two pistons when the outer piston 2 is stationary could perform back and forth.
  • the circumferential dimensions of the two rotary pistons are the same, i.e. the “piston segments” 18 extend radially to the same extent, this distance being only slightly smaller than the inner radius of the housing 1.
  • the "piston segments" of the two Rotating pistons have the same thickness, this thickness being only slightly smaller than the inner width of the housing 1.
  • a section 5 of the recess between the “piston segments” of the outer piston 2 and the inner piston 3 becomes one Combustion chamber which is delimited by "segment flanks" 6 and 7 forming working surfaces and the surface sections 8 and 9 lying on the "base circle” of the two pistons and by sections of the peripheral and side walls of the housing 1.
  • the two concentrically mounted shaft outlets 11 and 14 are each coupled by an oval wheel pairing on the work shaft 1 0 (Total torque shaft) together so that a space defined by the transfer function of the transmission positive movement of the rotary piston is produced. Since the two oval gears are shifted by 9 0 ° (two dead points) on the output shaft 1o 16 and 13, the movement period of the two rotary pistons with respect to also move the at 9 0 ° transfer function of an oval wheel pairing, thus taking place during the rotation movement of the two rotary pistons is forced from and to each other, ie a pressure acts on the two "segment edges" 6 and 7 a working chamber 5 over the angular range from minimum volume to maximum “chamber volume", a torque of the same size is transmitted from both rotary pistons to the shaft outlets 11 and 14, which, however, act in opposite directions.
  • the periodic gearbox has also reached its next dead position and the resulting torque of the output shaft changes its sign. In this working position, the chamber under pressure must be able to relax.
  • combustion chambers are formed from the two rotary pistons 2 and 3 and the housing 1, each of which undergoes two four-stroke processes during one revolution.
