Definitions

  • This invention relates to a piston machine, more especially to a machine of which the structural construction is both applicable for constructing engines, and for building pumps, compressors or similar.
  • the purpose of the invention is to provide a machine of which the weight, notwithstanding the use of a large number of cylinders, remains small in relation to the conventional embodiments of piston compressors and piston engines, whereby even a saving of 50% in weight and size can be achieved.
  • the purpose of the present invention is also a piston machine which operates almost noiselessly and with little vibration.
  • Another purpose of the invention consists in that a piston machine is provided whereby the combustion chambers or compression chambers can be produced in optimum dimensions without having to take into account the stroke lengths and crankshaft size.
  • the purpose of the present invention is also a piston machine whereby the piston rods perform an almost rectilinear movement so that almost no lateral pressure is exerted on the pistons through which less friction loss arises.
  • the intention of the invention is also a piston machine which, when it is produced in the form of an engine, shows almost no tilting effect during operation.
  • the invention concerns a piston machine, with as characteristic that it principally consists of at least one fixed cylinder arranged mainly parallel in relation to a central axis; a swash plate mounted at an angle, tiltable in all directions around a central point, located on the aforementioned central axis; a piston movable in the cylinder of which the free extremity of the piston rod is connected hingingly to the swash plate; and a rotatable part mounted axially on bearings in relation to the central axis, whereby the swash plate is coupled eccentrically to this rotatable part.
  • the piston machine can be produced both in the form of an engine and of a compressor or pump.
  • the machine is produced double sided, whereby along both sides of the swash plate a series of cylinders is arranged which work either only as engine, or only as compressor or pump or either partly as engine and partly as compressor or pump.
  • figure 1 shows schematically and in cross-section the piston machine according to the invention ;
  • figure 2 shows a cross-section according to line II- II in figure 1 ;
  • figure 3 shows a practical embodiment whereby the piston machine is produced as an engine
  • figure 4 shows a practical embodiment whereby the piston machine is produced at the same time as an engine and as pump or compressor;
  • figure 5 shows on larger scale a view of the part that is indicated by F5 in figure 4.
  • the piston machine principally consists of at least one, and preferably as shown six circularly arranged cylinders 1; a swash plate 2 tiltable in all directions, mounted at an angle; in the cylinders 1 movable pistons 3 with piston rods 4 of which the free extremities 5 are hingingly connected to the swash plate 2; and a rotatable part 6, whereby the swash plate 2 is eccentrically coupled to this rotatable part 6.
  • the aforementioned cylinders 1 are preferably arranged in a common cylinder block 7 and are hereby circularly arranged around a central axis 8.
  • the axial axes of the respective cylinders 1 are preferably parallel, or almost parallel to each other.
  • the swash plate 2 is at a specific angle A to the central axis 8 and can apart from that perform a rotating tilting movement, more especially around a central point 9 that is located on the central axis 8.
  • the piston rods 4 are hingingly attached by their free extremities 5 to well defined locations on the swash plate 2, for example by means of ball and socket joints 12.
  • the aforementioned rotatable part 6 is mounted on bearings axially in relation to the central axis 8.
  • the rotatable part 6 and the swash plate 2 are preferably connected to each other by means of parts meshing into each other, which are rotatable in relation to each other according to the perpendicular bisector 14 of the swash plate 2.
  • the swash plate 2 has a protruding shaft part 15, directed according to the perpendicular bisector 14, which fits into a seat 16 in the end face of the rotatable part 6.
  • the operation of the device can easily be deduced from figure 1.
  • the cylinders 1 are used as combustion chambers or expansion chambers and the successive pistons 3 are moved alternately to and fro with as result that the swash plate 2 performs a rotating tilting movement, which by means of the rotatable element 6 is converted into a rotating movement of the shaft 17.
  • the aforementioned shaft 17 is driven, through which the pistons 3 perform a reciprocating movement.
  • Figure 3 shows a double sided produced piston machine according to the invention, in other words whereby along both sides of the swash plate 2 a series, of for example six cylinders 1 are arranged. All piston rods 4 are connected to the same swash plate 2. Although in figure 3 the pistons 3 of the left and right part are presented in a same plane, in practice these lie displaced, such that the ball and socket joints 12 are situated alternately along the periphery of the swash plate 2.
  • the shaft 17 extends out through the left cylinder block 7, to outside the engine, where this shaft 17 is preferably provided with a flange 22, to which the part to be driven can be coupled.
  • the engine of the embodiment shown is of the two-stroke principle with injection.
  • the two-stroke principle is in itself sufficiently known.
  • FIG. 3 A specific detail of the embodiment from figure 3 however consists in that the injection pumps 23 are also driven by means of the swashs plate 2, more especially by piston rods 24 which are coupled to the swash plate 2 on a smaller diameter than the piston rods 4. Fuel is hereby sucked in by the pumps 23 via a pipe not shown and sent via a pipe 25 to the injector 26 in question.
  • FIG. 3 Another special characteristic of the embodiment shown in figure 3 consists in that the intake openings 18 and the intake valves 19 are situated around the respective piston rods 4, with as advantage that the rocking motions of the piston rods 4 do not impede the chambers 27 under the pistons 3 from closing in relation to the intake chambers 28, this because of the fact that the intake valves 19 can move sideways.
  • spark plugs 29 are suitably fired, for example by means of a distributor 30 which is electronically controlled by means of an electronic sensor 31 or similar coupled to the shaft 17.
  • FIG 4 a piston machine according to the invention is shown of which the part on the left of the swash plate 2 in the figure is produced as engine, while the part on the right thereof is produced as compressor.
  • an engine is hereby shown whereby the fuel is not supplied by means of an injector 26, but by atomization, by means of a atomizer 34, which is installed in the air intake 35 of the intake chamber 28.
  • the cylinders 1 shown in the righthand part of the figure, which provide the compressor operation, are each provided in classic manner with a gas intake channel 36, possibly provided with a filter 37, that exits via the intake valve 19 into the chamber 32 in question, and a pressure channel 38 connected to the exhaust opening 20 in which the exhaust valve 21 is placed.
  • the shaft part 15 is preferably mounted in seat 16 by means of an articulation, preferably a ball and socket joint 39.
  • an articulation preferably a ball and socket joint 39.
