Definitions

  • the "classic”, well-known reciprocating piston machine has pistons that only make a reciprocating movement.
  • the piston movement is usually generated by the crankshaft and connecting rod.
  • the disadvantages of the classic reciprocating piston machine include the friction of the reciprocating piston on the cylinder, the space required by the crank mechanism and normally the need for separate elements to control the inlets and outlets.
  • Rotary reciprocating piston machine here means a work machine or an engine.
  • a piston machine with one or more working spaces and with at least one piston, which carries out a rotary movement about the cylinder axis and at the same time an oscillating stroke movement parallel to the cylinder axis.
  • This piston machine is characterized in that this piston movement is generated by a bearing consisting of two parts which rotate relative to one another, the theoretical axis of this bearing not being parallel to the piston axis or e.g. to the cylinder axis, and in that either part of this bearing is attached to the piston or forms part of the piston and the other part is connected eccentrically to the cylinder, or that part of the bearing is attached to the cylinder or part of the cylinder forms and the other part, the short hollow shaft, is eccentrically connected to the piston.
  • the bearing is additionally combined with an electric motor or generator, or the short hollow shaft mentioned is used to mechanically transmit the power, or the stroke length or the compression ratio is adjustable, or the end faces (working surfaces) of the pistons are used, to synchronize the movement of the pistons or there is special lubrication of the pistons.
  • Figure 1 is a longitudinal section through a machine with four working spaces (7a and 7b), along the axis of a cylinder with the cylinder parts 1a, 1b, 1c.
  • the cylinder has openings (slots) in its wall, which are provided for the inlet (8, 10) and for the outlet (9, 11) of the working medium.
  • the slots are opened and closed by the pistons (2) and by the piston-like members (5).
  • the shape and this arrangement of the pistons of the slot-controlled rotary reciprocating machine relate to the subject of a separate patent application.
  • the object of the present invention is the way in which the movement of the rotary piston (2) is generated: a bearing consisting of two parts (35) and (38) is arranged obliquely with respect to the piston, that is, the axis ( 37) this bearing is not parallel to the axis of the piston.
  • the inner part (35) of the bearing is firmly attached to the piston (2).
  • the outer part (38) of the bearing is connected to the cylinder at the articulation point (39).
  • the two parts (35 and 38) of the bearing are rotatable relative to one another about their axis (37).
  • the pistons (2) make one stroke cycle, i.e. a reciprocating movement, per revolution.
  • the power is transferred from the piston to the outside by means of a central shaft (14).
  • the pistons (2) are connected to the central shaft (14) so that they are longitudinally displaceable along the central shaft, but that they transmit the torque to the central shaft (14).
  • Figures 2 and 3a, 3b show two examples of designs of the same type of the mechanism according to the invention, which leads the piston (2) to a rotary-stroke movement.
  • Figures 2 and 2a details of the section along the cylinder axis of a rotary reciprocating machine are drawn.
  • This mechanism corresponds to the mechanism illustrated in Figure 1, but the inner part (36) of the bearing is sunk into the piston (2).
  • the outer part (38) of the bearing rotates relative to the axis (37) of the bearing and is connected to the cylinder by a joint (39).
  • the hinge point (39) must be movable relative to the cylinder; or the connection between the bearing and the cylinder must allow a change in length.
  • FIGS. 4 and 5 show two examples of designs of another type of the mechanism according to the invention, which leads the piston (2) to the rotary-stroke movement. Details of the cut along the cylinder axis are drawn.
  • the hollow shaft (40) rotates about its own axis (41).
  • the piston (2) is connected to the hollow shaft at an eccentrically located point (42). When the hollow shaft (40) rotates, the piston (2) also rotates and additionally performs an oscillating stroke movement.
  • the articulated connection between the hollow shaft (40) and the piston (2) fulfills the following conditions: It must allow pivoting movements between the piston and the hollow shaft around all three coordinate axes or at least two coordinate axes. In the examples of FIGS. 4 and 5, a ball joint allows swiveling movements around all three coordinate axes.
  • these two coordinate axes must lie relative to the hollow shaft (40) in the plane which is perpendicular to the axis of rotation (41) of the hollow shaft.
  • the pivot point is therefore movable in an approximately radial direction to the axis of rotation of the piston (2) or in an approximately radial direction to the axis of rotation (41) of the hollow shaft.
  • cylinders all cylinder parts or non-moving parts connected to the cylinder, which could also be referred to as “housing” or “engine block” e.t.c, are called “cylinders”.
  • the invention relates to a piston machine with at least one piston (2), which has a rotary movement about the cylinder axis and at the same time a stroke movement parallel to the Executes cylinder axis and is characterized in that this piston movement is brought about by a bearing consisting of two parts which rotate relative to one another.
  • the axis of this bearing (37 or 41) is not parallel to the axis of the piston or the cylinder.
  • a part (35/36) of this bearing is attached to the piston (2) or is part of the piston, and the other part (38) is eccentrically articulated to the cylinder (1).
  • part of the bearing is attached to the cylinder or constitutes a part of the cylinder, and the other part, the hollow shaft (40), is connected eccentrically to the piston.
  • the piston performs a stroke movement per revolution.
  • the kinematics of this movement depend on the geometric details of the execution and can deviate from the sinus shape.
  • the kinematics are influenced, for example, by the size of the angle of the axis of the bearing; by the distance between the central axis of the bearing and the hinge point (39 or 42) which connects part of the bearing to the cylinder or to the piston; by the design of this articulated connection, in particular the design of the longitudinal displaceability of this connection, and by displacement of the joint (39 or 42) in the direction parallel to the axis of the bearing.
  • the structural design of the two parts of the bearing is carried out according to the known rules of technology, for example with axial and radial sliding bearings or with roller bearings.
  • Another version is characterized in that the power is mechanically transmitted to the outside of the machine by means of the hollow shaft (40) mentioned.
  • Another version is characterized in that the stroke length or the compression ratio or both is adjustable in that the angle which the axis (37 or 41) of the bearing has to the axis of the piston or the cylinder can be varied. This is achieved in that the bearing is pivotally attached to the piston or to the cylinder.
  • Another version is characterized in that the two adjacent end faces of two pistons (2) or a piston (2) and a piston-like member (5) always interlock positively like claws. - This synchronizes the rotation of neighboring pistons.
  • Another version is characterized in that the piston rests on a lubricating film, the lubricant, if it must not get into the working space or into the slots, being kept away from the working space or from the slots by a scraper ring or other sealing elements.
  • the rotating component of the piston movement is advantageous for hydrodynamic lubrication.
  • the sealing element is mounted on the cylinder, for example.
  • the working space (7) is delimited by two pistons (2), both of which perform a rotary stroke movement.
  • the movement of the piston is guided, for example, by the type of mechanism which is illustrated schematically in FIG. 4 or 5.
  • the hollow shaft (40) of this mechanism also transmits the power to the outside of the machine: for this purpose, the hollow shaft is toothed on the outside and transmits the power to a gearwheel, which is located outside the cylinder. This gear driven by the hollow shaft (40) is connected to the corresponding gear of the adjacent hollow shaft.
