Definitions

  • the "classic”, well-known reciprocating machine has pistons that only perform a reciprocating movement.
  • the piston movement is usually 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 is to generate the rotary stroke movement of the piston by means of axial and tangential force components, this piston movement being generated by electrical energy or electrical energy being generated by this piston movement.
  • a piston machine is provided 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, characterized in that this piston movement is brought about electromagnetically by means of an armature which is arranged obliquely to the axis of rotation or has curves in the axial direction, whereby the forces acting between the stator and armature have axial and tangential components.
  • stator Usually there are one or more locations on the stator, where the stator holds the lateral surface of the armature in the vicinity of these locations, whereby the armature executes the oscillating stroke movement according to its shape.
  • Figure 1 shows schematically a rotary reciprocating machine with the inventive electrical induction of the rotary stroke movement.
  • the stroke movement of the piston (2) together with the rotary movement results from the shape of the armature (20): the outer surface of the armature (20) is guided axially on the upper side by a concentrated magnetic field of the stator (21). At the bottom, the field of the stator is much wider axially.
  • the torque is basically generated in the same way as with conventional electric motors or electric generators.
  • the control of the charge exchange in a conventional manner is shown on the left with valves (29), on the right the slot control is influenced by the rotary movement of the piston (2) and the piston-like member (5).
  • the shape and arrangement of the piston in connection with the slot control in a rotary reciprocating machine is the subject of a separate patent application.
  • the following version, not shown, additionally strengthens the axial force component:
  • the stator acts not only with axial force components on the outer surface of the armature where it guides the armature.
  • the stator supports the relative axial movement of the outer surface of the armature at other points of the stator by driving electromagnetic forces. These driving forces oscillate in accordance with the movement of the surface area of the armature.
  • 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 executes 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 actuated with a time shift relative to each other.
  • FIG. 4 schematically shows another version similar to FIGS. 2 and 3.
  • the piston (2) executes two stroke cycles per revolution.
  • the armature is guided in two places 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 starting device.
  • 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 movement of the piston is brought about by means of an armature (20) which is arranged obliquely to the axis of rotation (see FIGS. 1 to 3) or has shafts in the axial direction (see FIGS. 4 to 6), as a result of which force acting between stator and armature has axial and tangential components.
  • the axial force components relate to the stroke movement
  • the tangential force components relate to the rotary movement.
  • stator holds the outer surface of the armature (20) in the vicinity of these points at one or more points of the stator (21). This means that the stator guides the outer surface of the armature at these points.
  • the number of guide points is advantageously equal to the number of lifting cycles per revolution, depending on the shape of the armature.
  • the electrical principle of the device according to the invention can be made very similar to any known principle of electric motors or electric generators. (See e.g. Figure 1).
  • the armature is made with magnetic poles or turns on it.
  • the armature is made of magnetizable but not permanently magnetic material.
  • This version can be implemented due to the non-rotationally symmetrical shape of the anchor.
  • the stator's electromagnetic field magnetizes the armature. Force and movement are generated and influenced by the arrangement and the time 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 axial displacement of magnetic poles or by electrically switchable poles, or by adjusting the strength of the magnetic force, which has an axial component.
  • Another version is characterized in that the two adjacent end faces of two pistons or a piston and a piston-like member (5) always remain in engagement with one another like claws. 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 area or into the slots, be kept away from the work area 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 normally makes either one, two or more stroke cycles per revolution. Two identical stroke cycles per revolution are advantageous.
  • the anchor is shaped according to 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 are arranged at identical angular distances from one another when viewed along the axis of rotation. Therefore our example 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.
  • These coils are arranged, for example, at an axial distance from one another and produce axial and axial-tangential force components. In the case of direct current, these windings or coils can be switched. In the case of multi-phase alternating current, the coils are arranged at the driving points in such a way that the driving electromagnetic fields move in accordance with the relative movement of the outer surface of the armature.
