Definitions

  • the "classic”, well-known reciprocating piston machine has pistons that only make a reciprocating movement. The piston movement is mostly 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 requirement of the crank mechanism and normally the need for separate organs to control the inlets and outlets. Piston machines that can be used universally have therefore been proposed, which avoid these disadvantages by simultaneously carrying out a rotary movement together with the reciprocating movement. Because of the typical rotation and stroke movement of the piston, this type of machine is hereinafter referred to as the "rotary piston machine”.
  • “Rotary reciprocating piston machine” here means a work machine or an engine.
  • A2 532 106 presented a machine which generates the rotary-stroke movement of the piston by means of a bearing which is inclined relative to the piston axis.
  • This bearing consists of two parts that rotate relative to each other. One part of the bearing is attached to the piston, the other part is articulated to the cylinder.
  • a disadvantage of this invention is that the bearing mentioned reciprocates and tumbles. It is therefore the object of the present invention to generate the rotary stroke movement of the piston in the piston machine by means of a device which, with its various designs, eliminates the problems and disadvantages mentioned.
  • 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 coaxial to the cylinder axis.
  • This piston movement is generated by a bearing consisting of two parts that rotate relative to each other.
  • This piston machine is characterized in that the theoretical axis of this bearing is not parallel to the cylinder axis and in that one part of the bearing is attached to the cylinder or forms part of the cylinder and the other part, hereinafter referred to as the hollow shaft, is articulated eccentrically with the piston connected is.
  • the axis of the bearing is therefore not arranged obliquely to the piston axis but rather obliquely with respect to the cylinder axis.
  • the theoretical axis of rotation of the bearing therefore remains stationary in the machine according to the invention, ie the bearing does not make any wobbling movements.
  • the central shaft can be dispensed with in this version, which otherwise serves to transmit the rotary movement of the pistons to the outside.
  • This central shaft has several disadvantages: For example, it goes through the middle of the work area, and seals must be provided between the piston and the central shaft.
  • the bearing is additionally combined with an electric motor or generator, 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 a special lubrication of the pistons .
  • Figures 2 and 3a, 3b show two examples of designs of the same type of mechanism which leads the piston (2) to a rotary-stroke movement.
  • 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 pivot point (39) must be movable relative to the cylinder; or the connection between the bearing and the cylinder must allow a change in length.
  • These mechanisms for generating the piston movement shown in FIGS. 1 to 3 correspond in principle to the prior art according to Th. Korsgren (US-A-2 532 106).
  • FIGS. 4 and 5 show two examples of designs of the new 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 pivot movements between the piston and the hollow shaft around all three coordinate axes or at least two coordinate axes allow. 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 hinge 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 called “housing” or “engine block” e.t.c, are called “cylinders”.
  • the present invention relates to a piston machine with at least one piston (2), which carries out a rotary movement about the cylinder axis and at the same time a stroke movement coaxial to the cylinder axis, this piston movement being brought about by a bearing consisting of two parts which rotate relative to one another.
  • This piston machine is characterized in that one part of the bearing is fastened to the cylinder (1) or forms part of the cylinder and the other part of the bearing, here called “hollow shaft” (40), whose theoretical axis of rotation is not parallel to the axis of the cylinder is leads and that the hollow shaft (40) is eccentrically connected to the piston.
  • the piston performs one 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 is influenced, for example, by the measure of the angle of the axis of the bearing, by the distance between the central axis of the bearing and the articulation point (42), which a part of the bearing connects to the piston by the design of this articulated connection, in particular the execution of the longitudinal displaceability of this connection, and by displacement of the joint (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 (41) of the bearing has to the axis of the cylinder can be varied. This is achieved in that the bearing is pivotally attached to the cylinder.
  • Another version is characterized in that the two adjacent, coaxially arranged end faces of the pistons (2) or of the piston (2) and the piston-like member (5), between which a working space is provided and which generate the compression ratio by relative stroke movement to one another , interlock like a claw. - This synchronizes the rotary movement.
  • Another version is characterized in that the piston rests on a lubricating film, the lubricant, if it does not get into the work space or into the slots may be kept away from the work area 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 area (7) is delimited by two pistons (2), both of which perform a rotary stroke movement.
  • the movement of the piston is guided by the type of mechanism illustrated schematically in Figure 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.
