Definitions
- the present invention relates to a piston machine according to the preamble of claim 1.
- Such piston machines are known.
- reciprocating piston engines according to the Otto or diesel process are known, in which the linear reciprocating movement of the pistons is converted into a rotational movement via connecting rods that cooperate with a crankshaft.
- the movement of the pistons is thus sinusoidal, the movement sequence of the pistons cannot be influenced, and the combustion process cannot be optimized, for example in combustion engines with regard to low-pollutant combustion.
- EP-A-0 702 128 shows a mechanism by means of which the linear reciprocating movement of the piston is converted into a rotational movement of a shaft via a cam disk.
- the movement characteristics of the piston can be adapted and optimized to the desired process, but due to the arrangement shown here, alternating forces, in particular transverse forces, act on the walls of the piston, which has a negative effect on the friction conditions and thus the wear on the piston corresponding friction surfaces is increased.
- the cam disc has a large difference between the largest radius and the smallest radius, as a result of which the roller rolling thereon, when the shaft has a substantially constant angular velocity, decelerates from a maximum speed to a minimum speed and to the maximum speed again during one revolution of the shaft is accelerated.
- the inertia of the mass of the roller causes sliding movements between the roller surface and the cam disc surface, which means that the wear is relatively great here too.
- the object of the present invention is to design a piston engine so that the conversion of the linear reciprocating movement of the pistons into a rotary movement of the shaft and vice versa can be obtained in such a way that the friction and wear can be kept as low as possible. Furthermore, the structure of the mechanism required for this should be simple and inexpensive.
- An advantageous embodiment of the invention consists in that the path on which the rollers roll runs in a hollow spherical shell, the center of which lies at the intersection of the pivot axis of the pivot lever with the axis of rotation of the shaft, and the surface of the path is directed towards the center in the radial direction and that the two rollers have the shape of a truncated cone, the tip of the cone defined by the truncated cone also being in the center defined above.
- a further advantageous embodiment of the invention consists in that the respective coupling rod is firmly connected to the corresponding piston and in the area in which it is articulated on the swivel lever is guided in a linear guide which is aligned parallel to the cylinder axis. This ensures that the pistons are optimally guided in the cylinder, the friction between the piston and the cylinder is very low, which means that wear and efficiency are improved accordingly.
- the articulation between the swivel lever and the coupling rod is designed such that the articulation point in the swivel lever is mounted so as to be displaceable essentially against its swivel axis and away from it.
- the arc movement of the pivot lever and the linear movement of the coupling rod can be compensated for without an additional intermediate member.
- a further advantageous embodiment of the invention is that the pivot lever is formed from a frame, between the two parallel legs of which the shaft runs and the two legs are each equipped with a journal, by which the pivot axis is formed and the journals each in a bearing are stored, which bearings are each held in a tab, which tabs are firmly connected to the housing.
- the bearings in the tabs which are firmly connected to the housing, are advantageously designed to be adjustable, as a result of which the pivoting lever can be adjusted and the two rollers can interact optimally with the web.
- the shaft is advantageously equipped with means for transmitting the rotational movement to further transmission elements, for example for controlling the valves and for driving further units.
- Another object of the invention is to provide a valve device for opening and closing inlet and outlet openings in a cylinder of a piston engine, in particular a piston engine of the type described above, which is simple in construction and has little wear.
- Claim 8 features listed.
- the sealing surface of the sealing plate is flat, the corresponding surface of the cylinder surface that surrounds the respective opening can also be flat, these surfaces can be obtained in a simple manner.
- a further advantageous embodiment of this valve device consists in that the sealing plate is held movably with respect to the pivot axis of the pivotable lever in such a way that the sealing surface of the sealing plate adjusts itself automatically with respect to the surface surrounding the respective opening. This ensures optimal tightness.
- a counterweight is attached to the sealing plate, which is arranged in such a way that when the sealing plate is opened and closed, it is essentially stationary with respect to the pivoting lever. Since there is practically no movement between the sealing plate and the pivoting lever, it is not necessary to provide lubrication, which considerably simplifies the construction.
- At least the sealing plate is made of a ceramic material. This provides the required temperature resistance without cooling, and warping and thermal stresses in the sealing plate, which could result from the cooling, are eliminated.

- each cylinder 3, 4, 5 and 6 there is a piston 7, 8, 9 and 10 arranged linearly.
- Each cylinder 3 to 6 is equipped with a valve device 11, with which the inlet and outlet openings of the respective cylinder 3 to 6 can be opened and closed, which valve devices 11 will be described in detail later.
- a coupling rod 12 is attached to each of the pistons 7, 8, 9 and 10.
- the coupling rod 12, which is connected to the piston 7, which moves in the cylinder 3, is articulated on an end region of a pivot lever 13.
- the coupling rod 12 of the piston 8, which moves in the cylinder 4 is articulated on the other end region of the pivot lever 13.
- the pivot lever 13 is pivotable in the center about a pivot axis 14, which is held in the housing of the piston machine, as will be described later.
- a roller 15 is also arranged at each of the two end regions of the pivot lever 13, the axes of rotation of which are each perpendicular to the pivot axis 14 of the pivot lever 13.
- the rollers 15 roll on a track 16 which is fixedly connected to a centrally arranged shaft 17 and which is provided with elevations and depressions, as will be described later.
- the coupling rod 12 of the piston 9, which can be moved back and forth in the cylinder 5, is articulated on one end region of a further pivot lever 18, while the coupling rod 12 of the piston 10, which can be moved back and forth in the cylinder 6, on the other End region of the further pivot lever 18 is articulated.
- This further pivot lever 18 is also equipped with rollers 19 in the same way as the pivot lever 13.
- the further pivot lever 18 is pivotable about the pivot axis 20, the axes of rotation of the rollers 19 are also perpendicular to this pivot axis 20, which is also held on the housing.
- the rollers 19 also roll on a track 24 which is firmly connected to the shaft 17.
- this heat engine By rotating the shaft 17, a gaseous medium is sucked and compressed alternately by the piston 7 and 8, which can be moved back and forth in the cylinders 3 and 4 via the coupling rods 12 and the pivoting lever 13, via an intake duct 21, the Valve device 11 opens and closes the inlet and outlet openings in a controlled manner.
- the compressed gas is discharged into a high pressure chamber 22.
- each of the pistons 7 and 8 each has slightly more than a quarter of a revolution of the shaft 17 for the pushing out of the Compressed gas available, so that the pushing out can take place at a low gas speed and the flow losses are correspondingly low.
- the course of the web 16 with its elevations and depressions is adapted to the characteristics of the valve device 11 and the corresponding flow conditions, so that a practically continuous and almost uniform gas flow flows from the cylinders 3 and 4 into the high-pressure chamber 22.
- Heat is supplied to the compressed gas in the high-pressure chamber 22, which can be done, for example, by burning a corresponding fuel in the high-pressure chamber 22, represented by reference numeral 23.
- the heat can also be supplied by a heat exchanger which can be operated, for example, by an external heat source , This external heat source can be operated practically as desired.
- the combustion gas expands and flows into the cylinders 5 and 6 via the valve device 11.
- the gas expands, the pistons 9 and 10 alternately retreat and drive via the coupling rod 12, the further pivot lever 18, the rollers 19 and the web 24 the Wave 17 on.
- the expanded gas leaves the cylinders 5 and 6 via the outlet openings controlled by the valve device 11.
- the combustion gas fills them again by slowly flowing over them and thus with little energy loss.
- the valve devices 11 are controlled in a known manner via the shaft 17 with the corresponding drive mechanism.
- the gas in the high-pressure chamber can be heated to a temperature of approximately 1500 Kelvin at a pressure of approximately 15 to 20 bar.
- the stroke volume of the cylinders that receive the heated gas is about 2.5 times as large as the stroke volume of the cylinders that suck in and compress the gas.
- the temperature of the outflowing gas is then about 470 Kelvin.
- Known throttle disks 56 can be used in the intake duct 21 in the area of the valve devices 11. Corresponding throttle disks are also used in the area of valve devices 11 of cylinders 5 and 6. As a result, the filling of the cylinders 3 and 4, which suck in and compress the gas, can be influenced. If the filling is not complete, the compression pressure becomes lower, which leads to a lower pressure in the combustion chamber. So much heat is supplied in the combustion chamber that a constant pressure is established in connection with the removal of the heated gas in the cylinders 5 and 6. This pressure can be measured and regulated via the heat supply. With the appropriate throttle disks, gas can be prevented from flowing back into cylinders 5 and 6.
- FIG. 2 in which a group 1 of the piston machine described in FIG. 1 is shown, it can be seen how the cylinders 3, 4, 5 and 6 and the shaft 17 are arranged in the housing 25.
- the pivot axis, not shown, is also mounted on the housing 25, as will be described later, about which the pivot lever 13 can be pivoted.
- the rollers 15 are each rotatably mounted on an end region of the pivot lever 13 and roll on the web 16.
- This track 16 is designed as a kind of ring surface which is formed by a hollow spherical shell 26.
- This hollow spherical shell 26 has a flattened part 27, to which, for example, a gearwheel 28 is fastened, and which is firmly connected to the shaft 17.
- the center of the hollow spherical shell 26 is located at the intersection of the pivot axis 14 of the pivot lever 13 with the axis of rotation 29 of the shaft 17.
- the surface of the web 16 is always directed towards the center in the radial direction.
- the rollers 15, which roll on the web 16, have the shape of a truncated cone, the tip of the cone defined by the truncated cone also being in the center.
- rollers 19 which are attached to the further swiveling lever 18, roll on a correspondingly shaped track 24, as a result of which the pistons 9 and 10 (FIG. 1) are moved back and forth in the cylinders 5 and 6. so that a detailed description can be dispensed with.
- An optimal rolling process of the rollers 19 on the corresponding web 24 is thus also achieved here.
- the coupling rods 12 are firmly connected to the pistons 7 and 8, as shown in FIG. 2.
- the coupling rods 12 are also firmly connected to the pistons 9 and 10, which move back and forth in the cylinders 5 and 6. Therefore, the coupling rod 12 is each guided in a linear guide 30 in the region of the respective pivot lever 13 or 18.
- the connection between the coupling rod 12 and the pivot lever 13 or 18 is designed such that the articulation point is mounted so as to be displaceable essentially against the pivot axis 14 or 20 of the pivot lever 13 or 18 and away therefrom, so that the arc movement of the pivot lever 13 and 18 and the linear movement of the coupling rod 12 can be compensated for without an additional intermediate member.
- the pistons 7, 8, 9 and 10 run optimally in the respective cylinders 3, 4, 5 and 6.
- the shaft 17 can drive further units, as shown in the lower part of FIG. 2, such as the control of the valve devices 11.
- the piston surfaces of the pistons 7, 8, 9 and 10 can be provided with a heat-insulating layer 57.
- the high-pressure chamber 22 (FIG. 1) can also be lined with heat-insulating material.
- the pivot lever 13 or the further pivot lever 18 has the shape of a frame 31.
- This frame 31 is formed from two legs 32 and 33, between which the shaft 17 runs.
- a bearing pin 34 is fastened, which engages in a bearing 35, which is held in a tab 36, which tab 36 is attached to the housing.
- the pivot axis 14 or 20 is thus formed by these two bearing pins 34.
- the two legs 32 and 33 are connected to one another at the end region with a connecting web 37.
- a bearing pin 38 is fastened, on which the roller 15 or 19 is rotatably and secured against axial displacement.
- Two webs 39 and 40 are fastened to the bearing pin 38 , which are each provided with a longitudinal contact 41.
- a bearing bush 42 is slidably inserted into these longitudinal slots 41, in which an axle piece 43 is held. This axle piece 43 is guided on both sides in the linear guides 30. The corresponding end is held on the bearing bush 42 in each case the coupling rod 12 With this mounting, the arcuate pivoting movement of the pivoting lever 13 or 18 can be compensated for the linear movement of the coupling rod 12
- valve device 44 with which an inlet or outlet opening 45 in a cylinder of a piston machine can be opened and closed.
- This valve device 44 consists of a pivot axis 46, to which a lever 47 is fastened.
- the pivot axis 46 is The pivotable lever 47 is provided with a slot-shaped recess 48, in which a web 49 comes to rest, which is fastened to the sealing plate 50.
- the pivotable lever 47 and the web 49 are provided with a continuous bore , in which an axle piece 51 is inserted. In the central region, the axle piece 51 has a spherical shape, on which the web 49 is mounted.
- the sealing plate 50 which closes the inlet or outlet opening in the closed state, is supported with its flat sealing surface 52 on the surface 53 of the cylinder surface surrounding the respective opening 45. Due to the possibility of pivoting the web 49 with respect to the axle piece 51, the sealing surface 52 of the sealing plate 50 adapts to the surface 53. This makes the seal optimal, the machining of the sealing surfaces is correspondingly easy. This configuration also allows thermal expansion of the corresponding material to be compensated for.
- the drive mechanism can have a known structure, it would also be conceivable to use a pivot lever with a roller that rolls on a path such as that used to move the pistons in the foregoing described piston engine is used.
- a counterweight 54 is therefore arranged on the web 49 on the side opposite the sealing plate 50.
- This counterweight 54 is arranged and designed such that the sealing plate 50, the web 49 and the counterweight 54 practically do not move during the opening and closing movement of the valve device because of the inertia with respect to the axle piece 51. It is therefore also not necessary to provide a lubrication device with which the bearing of the sealing plate would have to be lubricated. This simplifies the construction of this valve device.
- the material of the sealing plate 50, the web 49 and the counterweight 54 can be selected accordingly, for example it is advantageous to produce this part from a ceramic material.
- valve device 44 which has essentially the same structure as the one described above, but the axle bolt 51 is no longer provided with a spherical center piece and thus the sealing plate 50 with respect to this axle - Piece 51 is only pivotable about an axis and that the pivotability about the axis perpendicular to the axis piece 51 is achieved by a further pin 55, about which the pivotable lever 47 can be pivoted slightly about the pivot axis 46.
- This also optimally achieves that the flat sealing surface 52 of the sealing plate 50 adapts to the surface 53.
- the counterweight 54, the sealing plate 50, the web 49 and the counterweight 54 move as little as possible with respect to the axes of rotation, so that lubrication can also be dispensed with here.
- This valve device 44 can be used for all kinds of piston machines, for example heat motors, as described above, heat pumps, but also compressors, etc.
