Definitions

  • the "classic”, well-known reciprocating piston machine has pistons that only perform a reciprocating movement.
  • the piston movement is mostly generated by the crankshaft and connecting rod.
  • An electric motor or an electric generator is connected to the crankshaft to convert the power.
  • the reciprocating and simultaneously rotating movement of the piston has many advantages: the friction of the rotating piston is less, the additional rotation of the piston can improve the slot control and so on. Because of this typical piston movement, this type of machine is therefore referred to below as a “rotary reciprocating piston machine”, which means both a working machine and an engine.
  • the present invention now relates to electrically functioning devices for generating or converting the piston movement in such rotary reciprocating piston machines.
  • the object of the present invention and its various embodiments is therefore to effect the rotary-stroke movement of the piston in an electromagnetic manner by means of axial and tangential force components, to generate this piston movement by electrical energy, or to generate electrical energy by this piston movement.
  • a piston machine is provided with an armature and a stator, which are attached directly or indirectly to the piston or to the cylinder, characterized in that the armature is arranged obliquely to the axis of rotation of the piston or has curves in the direction of the axis of rotation and that the stator holds the surface of the armature near this location at least at one point by electromagnetic interaction in the vicinity of this location and thereby guides the armature in a rotary-stroke movement in accordance with the rotation-stroke movement program predetermined by the curve shape of the armature.
  • the armature When rotating, the armature performs the oscillating stroke movement corresponding to its shape, relative to the stator.
  • Figure 2a-b shows schematically details of another version of a rotary piston machine according to the invention.
  • Figure 2a shows a section along the cylinder axis
  • Figure 2b shows a section along the axis A-A.
  • the armature (20) is not permanently magnetic, but can be magnetized.
  • the piston (2) is connected to the armature and carries out one stroke cycle per revolution.
  • the pole (44) of the stator attracts the outer surface of the armature (20) with electromagnetic forces and therefore guides the armature in accordance with the armature shape.
  • the driving poles (45) of the stator have an alternating magnetic field and cause tangential and axial forces on the armature (20) due to the shape of the armature. The tangential forces generate a torque and the axial forces generate a force in the stroke direction.
  • the stator pole (46) also attached to the cylinder serves as an auxiliary pole for starting the machine.
  • Figure 3 shows a similar version of the device which produces the piston movement, but there are driving poles (45) at three points on the circumference.
  • the driving poles are activated with a time shift relative to each other.
  • Figure 4 shows schematically another version similar to Figures 2 and 3.
  • the piston (2) executes two stroke cycles per revolution.
  • the armature is guided at two points through guide poles (44) of the stator.
  • Driving poles (45) of the stator are arranged at the top and bottom of the drawing.
  • This version needs a starter.
  • Figure 5 shows a version similar to Figure 4.
  • a north pole and a south pole (44) of the stator guide the armature (20).
  • Driving poles (45) are present in four places. The driving poles are switched so that they cause a reciprocating axial-tangential force on the armature (20).
  • the guide poles (44) are designed, for example, as permanent magnets.
  • the stator has only driving poles (45). The poles (45) then have a predominantly attractive effect on the armature and drive and guide the armature in the correct rotary / lifting movement.
  • stator arranged on the outside has the functions and properties of the armature described.
  • armature has the described functions and properties of the stator.
  • Figure 6 shows in perspective the shape of the armature (20) of Figures 4 and 5.
  • cylinder all cylinder parts or non-moving parts connected to the cylinder, which are also called “housings” or “engine blocks” e.t.c. could denote, called “cylinder”.
  • the invention relates to a piston machine as a working or power machine with at least one piston (2), which carries out a rotary movement about the cylinder axis and at the same time an oscillating stroke movement coaxial to the cylinder axis, with an armature (20) which directly or indirectly with the piston and a stator (21) which is directly or indirectly connected to the cylinder (1), or vice versa, so that the armature relative to the stator performs the same movement as the piston relative to the cylinder.
  • the armature is limited in the radial direction so that it does not project beyond a theoretical cylinder surface lying coaxially to the axis of rotation, and the stator is limited in the radial direction so that it does not touch the same theoretical cylinder surface from the other side.
  • the piston machine according to the invention is characterized in that the armature (20) is arranged obliquely to the axis of rotation of the piston (see FIGS. 1 to 3) or has curves in the direction of the axis of rotation (see FIGS. 4 to 6).
  • the invention is further characterized in that the stator (21) at least at one point (44) holds the surface of the armature close to this point by electromagnetic interaction in the vicinity of this point and thereby the armature in accordance with the rotation predetermined by the curve shape of the armature -Lift movement program, which results in a rotary-stroke movement. This corresponds to an analogy to the known mechanical device with the guide elements and the cam track.
  • the number of guide points is advantageously equal to the number of lifting cycles per revolution, depending on the shape of the armature. Because of the shape of the armature according to the invention, it is easily possible in a number of different ways to induce torques and / or axial forces between the stator and armature in an electromagnetic manner.
  • One embodiment is characterized in that there are at least two points (45) on the stator, which are located where the nearby surface of the armature (20) executes major axial relative movements to the stator (see FIGS. 2 to 5). These points (45) are arranged at an axial distance from one another. Electromagnetic interactions are exerted between these points (45) and the armature (20) Have force components in the direction of these relative movements and therefore act on the movement of the armature.
  • Another embodiment is characterized in that the torque between the stator and armature is generated in principle as in the case of an electric motor producing only one torque (see, for example, FIG. 1), but the stator is at those points where the nearby surface of the armature carries out major axial relative movements , does not hinder these relative movements, since the stator does not have a narrow field in the axial direction at these points, in contrast to that point or those points (44) where the axial relative movement of the armature surface to the stator is small and where the armature is caused by an axially Direction of the stator's narrow field is guided axially.
  • the armature is made with magnetic poles or turns on it.
  • armature is made of magnetizable but not permanently magnetic material. Such designs can be implemented due to the non-rotationally symmetrical shape of the armature.
  • the stator's electromagnetic field magnetizes the armature. Force and movement are generated and influenced by the arrangement and the temporal sequence of the electromagnetic stator field and by the shape of the armature.
  • Another version is characterized in that the stroke length or the compression ratio or both is adjustable. This is done by axially shifting electromagnetic poles or by electrically switchable poles, or by adjusting the strength of the electromagnetic force which has an axial component.
  • Another version is characterized in that the two adjacent, coaxially arranged end faces of the pistons (2), or the piston (2) and the piston-like member (5), between which a working space is provided and which, by relative stroke movement to each other, the compression ratio generate, always interlocking like claws stay engaged. In this way, for example, the movement of the various pistons is synchronized.
  • Another version is characterized in that the piston rests on a lubricating film, the lubricant, if it must not get into the work space or into the slots, being kept away from the work space or the slots by a scraper ring or other sealing elements.
  • This sealing element is mounted in the cylinder wall, for example.
  • the armature of the following rotary reciprocating machine is attached to the piston and made of soft magnetic, i.e. made of magnetizable but not permanently magnetic material. This means that no power supply to the anchor is necessary.
  • the piston usually makes either one, two or more stroke cycles per revolution. Two identical stroke cycles per revolution are advantageous.
  • the anchor is shaped in accordance with FIG. 6.
  • the armature is guided through two magnetic poles, which are diametrically opposite one another on the stator.
  • the number of these guide points is equal to the number of identical lifting cycles per revolution; and these guide points, when looking along the axis of rotation, are arranged at identical angular distances from one another.
  • Our example therefore has two guide points and the angular distance between them is 180 degrees.
  • poles at these points are either permanent magnets or they are activated by coils.
