Definitions
- the invention relates to a Pleuelkolbenkompressor for admitting, compressing, moving or expanding and expelling a gaseous or liquid medium consisting of a housing having a compression chamber with a constant in the stroke direction of the piston profile and a connecting rod whose piston in its stroke direction complementary to the profile the compression chamber is shaped and transversely to the stroke direction, in which the compression chamber-contacting area is kugelsegment- or zylin- dersegmentförmig and the fixed piston connected to the connecting rod is pivotally connected to a crankshaft and at least one intake passage and at least one exhaust passage, both in the compression chamber are arranged and both are opened and closed by the piston of the connecting rod during its movement.
- a disadvantage of this arrangement are the considerable transverse forces acting on the cylinder walls, which cause increased wear of the piston, its seal and / or the cylinder.
- Another weakness is the joint between the connecting rod and the piston, which increases the number of parts to be manufactured and assembled and, like all moving parts, is subject to continuous wear. The joint increases the oscillating mass of the piston and thereby increases the load on the crankshaft bearings and deteriorates the concentricity of the engine or the compressor.
- the joint in the piston is successfully eliminated, but traded as a disadvantage that the piston is no longer flat against the wall of the cylinder.
- This not only affects the seal of the piston relative to the cylinder, but also rules out that the piston can open and close channels with its entire outer surface, via which in a pump, the medium to be pumped to and is discharged and over in a compressor or Compressor enters the medium to be compressed and is ejected again or over which occurs in an internal combustion engine, the medium to be burned and ejected after the end of the process as exhaust gas again.
- a "piston skirt” is arranged on the piston, which is shaped as a cylinder segment according to Figure 2. It remains unclear how such a cylinder segment can completely close the outlet despite the pendulum or tumble of the connecting rod piston.
- the piston part of the connecting rod piston consists only of a plane which is marked relative to the cylinder by a circumferential seal.
- Edges of the exhaust and intake ports are exposed to increased wear, which is still amplified by the hot exhaust gases when operating as a motor, which stroke along at the here anyway highly loaded point of the circumferential seal along.
- the invention presents that the profile of the compression chamber contains at least one plane which is oriented perpendicular to the direction of rotation of the crankshaft and which contains all the intake ports and all the exhaust ports.
- the cylinder of the invention thus has a plane in which all intake ports and all exhaust ports are arranged and which are covered by a likewise flat surface of the piston and thereby reliably sealed becomes.
- the key advantage of the relatively large surfaces between the piston and cylinder is that in the area of the intake and exhaust ducts of the piston overlaps these openings over a large area, so z. B. also occurs in the thermally highly loaded exhaust duct of a two-stroke engine wear only at the edge of the exhaust duct to the cylinder, but not on a thin, running around the piston seal.
- the piston part of the connecting rod rests on the cylinder wall in the other regions in which it is designed transversely to the stroke direction in the region in contact with the compression chamber, so that the cylinder wall forms a tangent to the cylinder segment of the piston.
- an absolutely inelastic piston and an absolutely inelastic cylinder wall only touch one another, which in practice, however, widens into a surface due to the ever-present elasticity of the material.
- this increased sealing effect is further enhanced by the fact that in the two crescent-shaped gaps between the cylinder segment-shaped piston and the flat cylinder wall by capillary action a lubricant and / or combustion residues and / or particles of the medium to be conveyed or to be compressed are collected and held by capillary action so that the actual sealing effect in practice is even higher than would theoretically be expected.
- the piston outside the flat surface, which sweeps over the intake and exhaust ducts designed spherical segment.
- the profile of the piston thus consists of a single straight line, which connects with its two ends to an arbitrarily curved line.
- intake and exhaust ducts are arranged in a common plane and the profile of the piston is exactly complementary to the profile of the compression chamber, so that a sufficient seal is always ensured.
- the profile of the piston consists of two opposing planes that are parallel to each other. The edges of these two planes are then connected to each other by two surfaces, which in principle can be freely curved.
- intake duct and exhaust duct are arranged on respectively opposite surfaces, which improves the gas exchange during engine operation.
- the profile of the piston is a rectangle. Then, the area of the piston contacting the compression chamber is no longer spherical segment-shaped, e.g. barrel-segmented or spherical, but designed as
- Cylinder segment shaped This form is particularly easy to manufacture. gene and bring with much less effort in the required for a sufficient sealing effect narrow tolerance limit.
- a further advantage is that, as an additional variant, a seal can be introduced between the piston and the compression chamber and / or, as a further variant, the two surfaces aligned perpendicular to the axis of rotation of the crankshaft can also be equipped with an additional seal.
- These gaskets can be applied not only as a plate-shaped material but also as a coating.
- the piston itself can be equipped with seals that are common in the prior art for reciprocating engines. These include one or more sealing strips, which are oriented transversely to the direction of movement.
- the piston is divided longitudinally and a spring-elastic layer is introduced between the two parts. This layer presses the parts of the piston against the wall of the compression chamber and can thus also compensate for thermally induced changes in the piston dimensions relative to the cross section of the compression chamber.
- the interior of a connecting rod piston compressor according to the invention consists of the compression chamber and the adjoining thereto the crankcase.
- the production of this shape is particularly simple when the housing around a connecting rod piston consists of two housing parts whose contact surface is oriented perpendicular to the axis of rotation of the crankshaft. Then the mold for a casting and the post-processing of these castings in a single clamping z. B. on a three-axis CNC machining machine done.
- both housing halves are identical, so can be created with only one change from a common mold or worked out of identical blanks.
- the housing of a connecting rod piston compressor When used as a compressor also creates heat loss, as when used as a combustion engine.
- the housing of a connecting rod piston compressor according to the invention can either have cooling fins for air cooling and / or channels for water cooling.
- the intake passage and the exhaust passage can be extended by appropriate continuations in the piston, which are activated when the piston reaches the respective channel.
- the intake passage in the passage flange is then extended through the piston intake passage in the connecting rod piston and the exhaust passage in the side flange through the piston exhaust passage in the connecting rod piston.
- Another channel which can be introduced as an additional option in the piston, when used as a two-stroke engine with an overflow channel and an adjoining inlet channel in
- connecting-rod pistons can be combined to form a multi-piston unit.
- Each connecting rod each has its own compression chamber and a separate crankcase and is connected to the crank pin of a common crankshaft.
- crankshaft with its numerous, compared to the axis of rotation cranked crank pin by a straight main shaft replaced, are arranged on the gears, each meshing with another gear, which is integrated in a separate crankshaft for each connecting rod. It makes sense to integrate at least one crank arm of this small crankshaft, which is provided separately for each individual connecting rod piston, into a toothed wheel.
- Two-stroke engine A typical feature of any two-stroke operation is that the aspiration of fresh gas in the crankcase occurs simultaneously with the compression of pre-compressed and pre-compressed gas in the compression chamber.
- a so-called overflow channel is required for forwarding the pre-compressed fresh gas from the crank chamber into the compression chamber.
- This overflow can z. B. be realized by a bore in a housing part, which is closed by a plug to the outside again. At one end of the overflow then another hole is introduced, which establishes the connection to the compression chamber as Flanscheinlasskanal. In the vicinity of the sealing plug, at least one further bore connects to the overflow channel, which connects the overflow channel to the crank chamber as a connecting channel.
- a connecting rod piston compressor according to the invention is in principle ready for use as a two-stroke engine: A fuel-air mixture is introduced via the intake passage and precompressed in the crankcase. It flows into the compression chamber via the connection channels, the overflow channel and the flange outlet channel, where it is further compressed during the upward movement of the piston and ignited approximately at the top dead center of the piston. With the downward movement of the piston, the remaining exhaust gas is expelled.
- operation in the four-stroke process is also possible. And that is when a single piston connecting rod via a gear on its own crankshaft meshes with another gear to output the torque. If a disc is arranged on this further toothed wheel, within which runs a channel which is connected at the moment of the intake of fuel-air mixture with the intake passage within the passage flange, then the intake passage sucks a fuel-air passage only every second revolution. Mixture. The oscillating piston does not suck in at the intermediate revolutions
- Fuel-air mixture but pure fresh air.
- the medium When such a previously described engine operates on the Otto principle, the medium must be ignited by a spark plug. When operating as an engine according to the diesel principle, the medium ignites itself from reaching a minimum compression itself.
- an inventive motor is suitable because the profile of its compression chamber, in contrast to many other oscillating piston engines over the stroke is constant. Then the motor may be e.g. operate in partial-load operation with auto-ignition over the entire volume and thus more efficient combustion. Only at very low and extremely high load, the compression is reduced and ignited the mixture through a spark plug.
- Motors can be configured, which can be configured as a series engine, V-engine, boxer engine, radial engine, W-motor or H-motor. It is a particular, principal advantage of the invention that each compression chamber in the longitudinal direction of the crankshaft relatively narrow and transverse to the crankshaft can be made relatively wide, so that a Center for the crankshaft can be made relatively wide, so that a Center for the crankshaft can be made relatively wide, so that a Center of the crankshaft.
- the two-stroke diesel engine is the engine principle with the highest efficiency at relatively low speeds and relatively large engine capacities.
- efficiencies of up to 55% are achieved in this configuration, outclassing fast-running four-stroke turbodiesel with an efficiency of at best approximately 40%.
- the connecting rod piston compressor according to the invention is the operation as a steam engine or compressed air motor.
- the admitted medium is a pressurized gas.
- the piston opens the intake passage and closes the exhaust passage, maintaining this configuration as it approaches the crankshaft until just before reaching bottom dead center.
- the penetrating gas drives the piston down.
- the piston closes the intake passage and opens the exhaust passage, maintaining this configuration as it moves back to top dead center.
- the piston closes the intake passage and opens the exhaust passage, maintaining this configuration as it moves back to top dead center.
- Figure 1 Open engine case with crankshaft and connecting rod at top dead center
- the housing 9 consists of two parts whose contact surface is perpendicular to the crankshaft 11. The one housing part is removed and gives the view of the contact surface of the remaining housing part, the side flange 16 free. In the side flange 16 of the crank chamber 18 and the adjoining compression chamber 19 are embedded. Because their side walls are arranged perpendicularly to the approximately keyhole-shaped base surface visible in FIGS. 1-6, they are only visible as lines in FIGS. 1-6.
- the connecting rod 8 is visible in Figures 1 to 6 in each changing positions. Since the compression chamber 19 in this exemplary embodiment has a rectangular profile in the stroke direction of the piston, the connecting-rod piston 8 also has a rectangular cross-section. In its, the viewer facing surface of the piston inlet channel 3 and the Kolbenansaugkanal 6 are embedded.
- the - in its side view about pear-shaped - connecting rod 8 is pivotally connected with its connecting rod with the crank pin 10 of the crankshaft 11, which is mounted in the center of the circular crank chamber 18.
- crank pin 10 is cut as the only element in Figures 1 to 6 and therefore hatched.
- the crankpin 10 is cut as the only element in Figures 1 to 6 and therefore hatched.
- the sealing webs 12 and 13 are drawn, on which slides the - in Figures 1 - 6 not visible - face of the piston. Also on the lateral plane of the piston additional seals 17 are located. In the simplest variant of a connecting rod compressor, however, the sealing sheets 12 and 13 and the seal 17 are not required.
- FIG. 7 shows a section transverse to the contact surface of the two parts of the housing 9, which corresponds to FIGS. 1-6. With these FIGS. 1 to 6, various characteristic positions of the connecting-rod piston 8 are explained.
- the connecting rod 8 is shown in its position at top dead center. Good to see that the compression chamber 19 has shrunk to its minimum volume between the connecting rod 8 and the motor housing 9.
- the connecting rod at top dead center ignited to its maximum value in the combustion chamber 19 ignitable mixture - the diesel process by self-ignition at very high compression, the Otto process by a - not shown here - Spark plug.
- the exhaust passage 5 in the side flange 16 is covered by the connecting rod 8 and thereby shut off. Since it is arranged in an actually invisible plane, it is shown in dashed lines.
- the intake channel 7, which is arranged in the - actually drafts dismantled - channel flange 15 and thus also is arranged in a plane which is not visible in Figure 1.
- the fuel-air mixture has expanded after its ignition and the connecting rod 8 pushed so far down that he has opened the exhaust passage 5 via the piston exhaust passage 4 in the connecting rod 8 and extended into the compression chamber 19 into it.
- the piston exhaust passage 4 located in the connecting rod 8 extends parallel to the plane of the drawing, the exhaust passage 5 perpendicular to it in the side flange 16, a part of the housing 9, into it.
- the engine principle according to the invention thus provides, in contrast to hitherto known two-stroke engines with slot control, a considerably better separation of fresh gas and exhaust gases, as a result of which a serious disadvantage is virtually eliminated.
- crankshaft 11 has rotated slightly further in relation to FIG. 2, so that the connecting-rod piston 8 establishes a connection between the crank chamber 18 and the combustion chamber 19.
- This connection takes place via two connecting channels 2, which in FIG. 3 run out of the crank chamber 18 approximately perpendicular to the viewer into the overflow channel 14, which runs parallel to the image plane in the drawing flange 15, which is why these elements are shown in dashed lines.
- the air-fuel mixture already pre-compressed in the crank chamber 18 flows at the upper end of the overflow channel 14 through the inlet channel 1 and the piston inlet channel 3 in the connecting-rod piston into the
- the inlet channel 1 like the connecting channels 2, is oriented perpendicular to the observer and therefore only recognizable as a dashed circle in FIGS. 1-6.
- Figure 4 thus shows a position of the connecting rod 8, in which it closes all channels.
- crankshaft 18 removed.
- the connecting-rod piston 8 establishes a connection to the intake passage 7 via its piston intake passage 6.
- the intake duct 7 extends in the drawing - dismantled - channel flange 15 perpendicular to the viewer and in the plane parallel to the plane extending Kolbenansaugkanal 6 inside. About these two channels, the crank chamber 18 is filled with fresh air fuel mixture.
- the exhaust passage 5 does not overlap with its counterpart in the connecting rod, the piston exhaust passage 4.
- the inlet passage 1 is also to its counterpart, the piston inlet passage 3 on the connecting rod 8, spaced.
- FIG. 7 corresponds to FIGS. 1-6 with different positions of the connecting rod piston 8 in the same engine and shows the section through the engine housing in the two different cutting planes A-A parallel to the crankshaft 11 and A-B through the crankshaft 11.
- the housing 9 consists of two parts, the channel flange 15 on the left side and the side flange 16 on the right side.
- the side flange 16 includes the exhaust passage 5 and the channel flange 15, the intake passage 7.
- As a further channel connection of the overflow channel 14 is installed in the channel flange 15. It is connected by two connecting channels 2 with the crank chamber 18 and through the inlet channel 1 with the compression chamber 19th
- FIGS. 1-6 The 7 screws shown in FIGS. 1-6 for connecting the two housing parts of channel flange 15 and side flange 16 are omitted in FIG. 7 for the sake of clarity.
- the section through the engine is drawn in two different sectional areas in Figure 7:
- the sectional area AA of the left half and the sectional plane AB are shown in Figure 1 ,
- the sectional area AA runs in the lower part through the overflow channel 14 and bends in the upper part and is then identical to the sectional plane AB of the right half of Figure 1.
- the sectional plane AB extends on the axis of symmetry of the compression chamber 19 and crank chamber 18 through the
- the kinked cut surface AA of the left half of the picture cuts the connecting rod 8, the crank chamber 18 and the disk-shaped parts of the crankshaft 11 on a different cutting line than in the right half of the picture, which explains the difference between the two halves of the picture:
- the section through this disc is a much larger rectangle than in the left half of the picture in section A-A, which only cuts the same size, second disc on the crankshaft 11 outside its center.
- two connecting rods 8 are each shown without cylinders in their basic arrangement as a V-engine.
- the axes of rotation of their own, small crankshaft 11 point to the viewer.
- Two connecting rod 8 or two rows of connecting rod 8 are arranged at an angle V to each other.
- a first gearwheel 23 is arranged for each connecting-rod piston 8, each with a second gearwheel 22 on the main shaft 21 meshes.
- the main shaft 21 collects the torques generated in the individual connecting rod 8 and performs them together. A through the entire engine through going, expensive community crankshaft is spared. Instead, numerous gears are used.
- a gear ratio between the small gears 23 on the respective own crankshaft 11 of each connecting rod 8 and the large gears 22 on the main shaft 21 of 1: 2 is located.
- - not shown in Figure 8 - channels in the large gear 22 occur only at every other revolution with a corresponding opening in the crank chamber of each connecting rod 8 in connection.
- This can be achieved, for example, that only every second revolution of the crankshafts 11 ignitable fuel-air mixture reaches each connecting rod 8.
- Such a work rhythm corresponds to a four-stroke engine. It is advantageous after ejecting the exhaust, the good flushing of each compression chamber with fresh air. As a result, considerable advantages are achieved in the exhaust gas purification.
- crankpin of the crankshaft 11 11 crankshaft, hingedly connected to at least one
- crankcase part of the housing 9, enclosed by the channel flange 15 and side flange 16th
