  • a rotary piston machine of this type is known from DE-PS 21 02 694.
  • the disk-like piston slides which are displaceable radially to the rotor axis in the rotor, are guided in annular grooves via lateral guide cheeks extending towards the rotor axis and sliding blocks articulated thereon, which are incorporated in both side walls of the fixed inner body.
  • the disk-type piston spools are guided essentially outside of the work rooms in such a way that the outer edges of the piston spools move without contact inside the housing jacket inner wall and to this - no centrifugal forces are transmitted to them.
  • the invention is based on the object of further improving the guidance of the piston slides in a rotary piston machine of the type mentioned at the beginning.
  • This object is achieved in that guide rings are rotatably mounted in the side surfaces of the inner body around the housing axis and have concentric elongate recesses which extend into the housing axis and into which the guide bodies of the piston slides engage.
  • the rotary piston machine according to the invention has the advantage that closed guide rings rotate at the speed of the rotor on the cylindrical guide surfaces on the sides of the inner body, and the guide bodies have only a relatively small movement caused by the eccentric arrangement of the rotor axis relative to the axis of the housing ⁇ Complete half of the recesses in the guide rings.
  • These guide rings absorb all the centrifugal forces of the piston slide, so that no centrifugal forces act on the cylindrical sliding surfaces of the inner body.
  • the guide bodies, which are fabric of sliding blocks of the rolls can be kept small, so that the result of the eccentricity per cycle to be accelerated 'and ver ⁇ hesitant masses are small.
  • FIG. 1 a side view of the rotary machine according to the invention with the housing side wall removed and partly in section
  • FIG. 2 shows a view along the section line II-II in FIG. 1.
  • the rotary piston machine consists of a stationary housing with a cylindrical inner body 3, a cylindrical housing shell 11 and side walls 12 and 13 and a rotor arranged eccentrically to the housing with a rotor ring 25, side disks 23, 24 and a rotor shaft 21.
  • the cylindrical housing shell 11 is provided with cooling fins 10.
  • the housing has an annular space which is divided by the rotor ring 25 into a crescent-shaped inner working space A1 and into a crescent-shaped ( outer working space A2).
  • the side plate J connects the rotor ring 25 to the shaft 21 in a rotationally fixed manner.
  • the cylindrical inner body 3 is arranged centrally in the housing and is firmly connected to the side wall 13 of the housing via a cylindrical connecting piece 31 which is eccentric to the cylinder axis 14 and coaxial to the rotor.
  • guide grooves 28 which extend radially to the housing axis 14 and in which the piston slides 4 are guided with their lateral guide cheeks 45 so as to be radially movable.
  • guide rings 50 are rotatably supported, which have recesses 51 into which guide bodies 43 engage, which are articulated on the lateral guide cheeks 45 guided radially in the guide grooves 28.
  • the piston slides 4 are guided by the guide bodies 43 so that their rounded outer edges 41 abut the inner wall of the housing shell 11 without friction.
  • the rounded inner edges 42 of the piston slide 4 also bear against the cylindrical surface 32 of the inner body 3 without friction. Between the segments of the rotor ring 25, the spool 4 are slidably sealed by means of sealing elements.

  • the elongate recesses 51 in the guide rings 50 which extend concentrically to the housing axis 14, extend in the longitudinal direction so far that the guide bodies 43 can move back and forth during one revolution of the rotor without bumping against the two ends of the elongated recess 51.
  • the guide rings 50 can be mounted with their cylindrical inner surfaces 52 on a cylindrical shoulder on both sides of the inner body 3. In this case, the outer diameter of the guide rings 50 can be almost as large as the outer diameter of the inner body 3.

  • the guide rings 50 are driven by alternating one piston slide 4 with its two
  • Guide bodies 43 advance the guide line 50, specifically by mechanical means or by pressure pads which are located between the guide bodies 43 and the front end faces of the elongated recesses 51. Both in fig. 1 illustrated embodiment take over five piston slides 4 after one rotation of the rotor 4 in succession to this drive of the guide line 50.
  • the mode of operation of the internal combustion engine according to FIGS. 1 and 2 is as follows:
  • Air or a fuel-air mixture is sucked into the inner crescent-shaped working space A1 through two suction channels 35 arranged in the inner body 3 and passed through the connecting piece 31 and is compressed in the area of the inner working space A1 that becomes smaller in the direction of rotation of the rotor.
  • the compressed air is transferred via an overflow channel 17 in the compression area of the outer working space A2.
  • a second inlet 15 opens into the outer working space A2. Fresh air is sucked in through this second inlet 15 and then compressed, supplying the air compressed in the inner working space A1 or the air-fuel mixture. If a piston slide 4 reaches the ignition channel 18, the ignitable mixture in front of this piston slide 4 has the highest compression and is ignites.
  • the piston slides 4 which are guided radially to the rotor axis 22 in the guide grooves 28 and tangentially to the housing axis 14 in the recesses 51 of the guide rings 50, transmit the forces acting on them via the segments of the rotor ring 25 and via the side plate 24 to the rotor shaft 21.

Abstract

Machine à piston rotatif à vitesse de rotation et compression élevées, avec engrènement par déplacement et glissement, en particulier un moteur à combustion interne, avec a) un logement fixe constitué d'un corps intérieur cylindrique (3), de deux parois latérales (12, 13) et d'une enveloppe (11) de logement cylindrique agencée coaxialement au corps intérieur (3), et entourant une chambre annulaire; b) un rotor disposé excentriquement par rapport à l'axe (14) du logement, et comportant un arbre (21) de rotor, une bague (25) de rotor tangentielle à l'enveloppe de logement/paroi intérieure, divisant la chambre annulaire du logement en une chambre de travail intérieure (A1) en forme de croissant et en une chambre de travail extérieure (A2) en forme de croissant, et deux disques latéraux (23, 24) dont l'un relie la bague (25) de rotor à l'arbre (21) de rotor solidairement en rotation; c) plusieurs coulisseaux (4) de piston dans la bague (25) de rotor, se déplaçant radialement par rapport à l'axe (22) du rotor, lesquels coulisseaux, au moyen de rainures (28) de guidage ménagées dans les disques latéraux (23, 24), sont guidés radialement et, via des surfaces de guidage (45) s'étendant des deux côtés du corps intérieur (3) en direction de l'axe (14) du logement et via des éléments de guidage (43) articulés auxdites surfaces de guidage, sont guidés sur des surfaces de guidage cylindriques situées concentriquement à l'axe (14) du logement dans les surfaces latérales (33, 34) du corps intérieur (3) de telle sorte que leurs bords extérieurs (41) sont maintenus à une faible distance de l'enveloppe de logement/paroi intérieure (11) et leurs bords intérieurs (42) sont maintenus à faible distance du corps intérieur cylindrique (3).
