Description

The The invention relates to an apparatus and a method for compacting and / or displacing one Fluids, in particular a rotary piston compressor according to the preambles the claims 1 and 38 and a pump, a hydraulic force transducer and an internal combustion engine according to the preambles the claims 39, 40 and 41.

It are devices for compressing or displacing a fluid with a Displacement room and a piston known in which by the movement of the piston a volume change of the displacement room causes and in this way a befindliches in the displacement fluid compacted and / or displaced becomes.

Such Devices are used, for example, in internal combustion engines, in which a piston is a gaseous Compressed fluid in the displacement chamber, wherein the internal combustion engines by the design of their piston differ. In the most famous internal combustion engines, the gasoline engine and the diesel engine, the piston is performing as a lifting movement Hub piston designed, while the rotary engine, however, comes a rotating Rotary piston used.

The Different engine types have in common that they are the ones in a fuel convert stored chemical energy into mechanical work. The Type of energetic implementation is similar and occurs in the different internal combustion engines by converting the chemical energy into heat and then converting it the heat in mechanical work. The transformation of the chemical energy takes place by combustion of the fuel, the implementation of heat energy in mechanical work by their transfer to a fluid whose Pressure increases and with the resulting expansion mechanical Work done. In conventional Internal combustion engines are made by the lifting movement of a reciprocating piston or the rotational movement of a rotary piston for this purpose, first a Compression of the fluid in the displacer caused by the movement of the piston and one caused by the piston movement Reduction of the displacement chamber. In the compressed fluid fuel is injected, and the resulting fuel mixture formed from the fluid and the fuel is ignited. By the combustion of the fuel mixture increases the pressure inside the displacer, the fluid expands and drives the piston. This way will the chemical energy stored in the fuel into kinetic energy implemented, the reciprocating piston a lifting movement and the rotary piston causes a rotational movement of the piston and a torque at one Wave generated.

petrol and diesel engine differ in particular by the resulting Compression of the fluid in the displacement chamber and the ignition process. When gasoline engine is a compression of the displacement in the space fluid from atmospheric Pressure up to 20 to 30 bar, so the fluid experiences by the piston movement a compression ratio from compressed to uncompressed mixture of 20 to 30 1. An inflammation of the compacted, heated to a temperature of 400 to 500 ° C. and fuel mixed fluid is via an external spark. In the case of the diesel engine, on the other hand, the fluid will change depending on the design of the diesel engine compressed to up to 110 bar, so the fluid undergoes a compression ratio of 110 to one and is heated to 700 to 900 ° C, so that a ignited in the compressed fluid injected fuel itself.

at a reciprocating engine, it is disadvantageous that measures to balance the mass of a lifting movement exporting Reciprocating pistons are necessary to ensure the smoothness of the engine and mass forces acting on the engine and moments to compensate. This problem is caused by a rotary piston arrangement avoided with a rotating rotary piston, so that separate activities are not required for mass balance. In one embodiment the rotary piston arrangement, the Wankel engine, divides the rotary piston an epitrochoid trained displacer in three subspaces, in which a fluid through the rotation of the means of a Exzentertriebes in the displacement room circulating rotary piston is compressed. The cross section of the rotary piston is in the plane of rotation, ie in cross-section perpendicular to its axis of rotation, shaped like an equilateral triangle with concave sides in his corners, while the revolution of the piston run along the housing, sealing areas on.

adversely in such a rotary piston arrangement is that through the rotary piston created displacement form unfavorable is and to high fuel consumption and high pollutant emissions leads. About that In addition, devices using rotary piston assemblies are in limited their achievable compression ratios and thus in their uses limited. In particular, with such devices is not similar to the diesel engine Construction of an internal combustion engine with auto-ignition possible.

Of the present invention is based on the object, devices and to provide methods for compressing and / or displacing a fluid, with which can be achieved a quiet running behavior, the effective displacement and / or high compression of the fluid and versatile are.

The The object is achieved by a device having the features of the claim 1, a method with the features of claim 38 and a pump, a hydrodynamic torque converter and an internal combustion engine with the features of the claims 39, 40 and 41 solved.

A solution according to the invention provides a device, in particular a rotary piston compressor for compressing and / or displacing a fluid in at least one displacement chamber, wherein the device comprises a rotary piston which is arranged rotatably about a rotation axis in the displacement and so in a plane of rotation which is perpendicular to the axis of rotation extends, is rotatable. there

• A pendulum segment is arranged on the rotary piston,
• The pendulum segment is pivotable about a pendulum segment axis parallel to the plane of rotation of the rotary piston in order to perform a pendulum movement relative to the rotary piston during a rotation of the rotary piston about the axis of rotation,
• - Shares the rotary piston together with the pendulum segment the displacer in two subspaces, which are each increased or reduced by the rotation of the rotary piston about the axis of rotation, wherein the total volume of the displacer remains constant, so that an enlargement of the first subspace causes a reduction of the second subspace and vice versa.

The inventive solution provides thus a device available through the rotary piston and arranged on the rotary piston Pendulum segment the displacer in two subspaces divided by the rotational movement of the rotary piston and the pendulum motion of the pendulum segment relative to the rotary piston alternately enlarged and be downsized. The volume change of the subspaces takes place doing so in a differential way, so that at constant total volume of the displacement room the reduction of the first subspace to an enlargement of the second subspace leads. The pendulum segment is arranged on the rotary piston, that it is pivotable in the plane of rotation of the rotary piston and while the rotation of the rotary piston about its axis of rotation a pendulum motion around the pendulum segment axis relative to the rotary piston performs. By the pendulum movement creates the pendulum segment together with the rotary piston sealing division of the displacer space in two subspaces.

With the solution according to the invention becomes a Device created by means of the rotational movement of the rotary piston and the simultaneous pendulum motion of the pendulum segment a division of the displacement room into two subspaces, in a differential manner by the rotational movement of the rotary piston enlarged and reduced become. The device according to the invention thus provides a piston assembly with a rotating piston to available the size Displacement and / or compression ratios one in the subspaces of the displacement room located fluid allows and at the same time ensuring a smooth turning behavior, so that the device also for high speeds is suitable. The device thus combines the Advantages of a reciprocating piston arrangement with those of a rotary piston arrangement, in particular, by the device compression and / or displacement ratios as with a reciprocating piston and a running behavior as with a rotary piston possible power. With the device according to the invention are therefore completely new Designs, for example, a motor, a pump or a force transducer conceivable, which is characterized by a high achievable compression and / or Displacement ratio at at the same time more efficient and smoothly working.

Preferably changes the volume of at least one of the subspaces during a rotation of the rotary piston about its axis of rotation from a minimum residual volume to a Maximum volume and again to the minimum residual volume. On this one learns in the subspace located fluid through the rotation of the rotary piston a very big Compaction and / or displacement, the only through the compressibility of the fluid and the residual residual volume of the subspace is limited.

The displacer is preferably arranged in a housing in which the rotary piston is rotatably mounted. The rotary piston divides together with the pendulum segment the displacer in two subspaces by the rotary piston during its rotation about its axis of rotation at least on a housing portion sealingly along and the pendulum segment simultaneously sealingly abuts a further housing portion. The pendulum segment and the rotary piston are designed so that they behave sealingly to each other during the pendulum movement of the pendulum segment and herzustel to make a sealing connection len, at least a portion of the pendulum segment rests against at least a portion of the rotary piston.

The Oscillation of the pendulum segment is thereby by the physical personnel on the pendulum segment during the rotation of the rotary piston causes about its axis of rotation. Especially is the pendulum segment acting by acting on the pendulum segment, by the rotational movement of the rotary piston and on the Rotary piston arranged pendulum segment caused centrifugal forces deflected and to a housing section pressed. However, it is also conceivable to forcibly control the pendulum movement of the pendulum segment, so as to ensure that the pendulum movement of the Pendulum segment is synchronous to the rotation of the rotary piston and a sealing division of the displacement by the pendulum motion ensured the pendulum segment is.

In a preferred embodiment, the rotary piston of the device at least one base plate, which is perpendicular to the plane of rotation perpendicular extends to the axis of rotation of the rotary piston and about the axis of rotation the rotary piston is rotatably disposed in the housing. On the base plate and firmly connected to this, a closure element is arranged, which extends on the base plate and is formed so that for one while the rotation of the rotary piston sealing along at least one housing section runs and thus the seal between the housing and produces rotary piston and the other during the pendulum movement of the Pendulum segments relative to the rotary piston sealingly on a surface of the Pendulum segment is applied so as to seal between rotary piston and pendulum segment effect. By the formation of the closure element and the sealing effect between rotary piston and housing, rotary piston and pendulum segment and pendulum segment and housing, caused by the pendulum motion, becomes the division of the displacer in two subspaces guaranteed.

Preferably is the cross section of the closure element parallel to the plane of rotation of the rotary piston sickle-shaped educated. In this case, the closure element can be parallel in cross section to the plane of rotation of the rotary piston through an outer side, one measured by the axis of rotation of the base plate outer radius RA, and by an inside, one from the pendulum segment axis measured internal radius RI, be defined, wherein for training the sickle shape of the inner radius RI greater than the outer radius RA is. The outside the closure element moves during the rotation of the rotary piston along a housing section, and the inside shows the pendulum segment. While the pendulum moves the pendulum segment along the inside of the closure element, wherein the pendulum segment is such that the inside the closure element facing side of the pendulum segment sealing on the inside of the closure element and thus on the rotary piston is applied.

The Pendulum segment is according to the invention to the Pendulum segment axis rotatably mounted on the rotary piston. there the pendulum segment axis is preferably arranged on a base plate, is offset from the axis of rotation of the base plate by a distance D. and extends perpendicular to the plane of rotation, so that the pendulum segment in the plane of rotation of the rotary piston relative to the rotary piston can be pivoted. Preferably, the pendulum segment in cross section a curved side parallel to the plane of rotation of the rotary piston which can be described by a radius RI about the pendulum segment axis is. The curved one Side of the pendulum segment and the inside of the closure element have a similar one Shape and curvature and are both described by the radius RI about the pendulum segment axis. The pendulum segment is arranged on the rotary piston, that the curved one Side of the pendulum segment to the inside of the closure element shows, so that the pendulum segment so to the pendulum segment axis can be moved while keeping the curved side of the pendulum segment sealingly applied to the inside of the closure element.

Around the sealing division of the displacer space in two subspaces to reach the pendulum segment during the rotation of the rotary piston about its axis of rotation on a housing section and makes a pendulum movement for this purpose. Prefers the pendulum segment is doing with one of the end portions of the curved side while the rotation of the rotary piston around its axis of rotation sealing on casing on, wherein always one of the end portions of the curved side rests against the housing, while the rotation of the rotary piston about its axis of rotation sections but also both end portions of the curved side can touch the housing.

The pendulum segment is preferably shaped in cross-section parallel to the plane of rotation in the region of the end portions of the curved side of the pendulum segment. In an advantageous embodiment, the end portions of the curved side can in particular each describe by a radius RZ to a center of the end portions of the curved side on the shuttle segment spaced from the pendulum segment axis be bar. The end portions of the curved side are preferably arranged so that they have a maximum distance of 2RA to each other along a line which is defined by the center points associated with the end portions of the curved sides. The position of the centers of the curved portion end portions on the shuttle segment is determined by the line defined by the midpoints of the end portions passing through the axis of rotation of the base plate of the rotary piston when the shuttle segment is in a non-deflected position centered relative to the rotary piston, Thus, the pendulum segment is in its normal position in which it is arranged symmetrically to the connecting line of pendulum segment axis and rotation axis of the rotary piston, ie in the central position during its pendulum motion.

In an advantageous variant can the end portions of the curved Side of the pendulum segment also as in cross section parallel to the plane of rotation of the rotary piston circular, extending perpendicular to the plane of rotation of the rotary piston Seal elements may be formed, which in each case about an axis of rotation rotatably mounted on the pendulum segment and described by a radius RZ are. By using such separate sealing elements, which are rotatably mounted on the pendulum segment, the friction between casing and pendulum segment during minimizes the rotation of the rotary piston about its axis of rotation, Material wear reduced and the working behavior of the device can be improved.

The further shaping of the pendulum segment in cross section parallel to Rotation plane is basically arbitrary and serves to the curved side of the pendulum segment and the sealing on a housing portion adjacent end portions of the curved side with the pendulum segment axis to connect. An advantageous embodiment has two more Sites that are designed to be with their essentials Extension directions approximately at an angle in the range up to 90 ° to each other form and each with an end portion of the curved side of the pendulum segment are connected. The contour of the pendulum segment has in this case ie in cross-section parallel to the plane of rotation of the rotary piston roughly the shape of a pie-shaped circle segment, that through the curved, the closure element facing side and the two other sides in cross-section parallel to the plane of rotation of the rotary piston is limited.

Prefers is the case the device is formed so that there is a first wall portion whose contour in cross-section parallel to the plane of rotation of the rotary piston describes a circular section and by the radius RA is spaced from the axis of rotation of the base plate. The first wall section circumscribes an angle greater or equal to 180 ° and is arranged so that the rotation axis of the rotary piston is in the fictional center of the first wall section descriptive Circle is located so that the arranged on the rotary piston Closure element whose outside also by the radius RA about the axis of rotation of the rotary piston is describable while the rotation of the rotary piston sealingly about its axis of rotation along the first Wandungsabschnitts moves.

Furthermore shows the case a second wall portion, whose contour in cross section preferably parallel to the plane of rotation of the rotary piston represents a circle section defined by a radius RA, wherein the center of the second wall portion relative to the center spatially offset from the first wall section can be. The pendulum segment movement is then such that one of the end portions of the curved Side of the pendulum segment on one of the two wall sections rests and thus causes the sealing division of the displacement in two subspaces.

Around to ensure, that the pendulum segment rests against one of the two wall sections of the housing and the displacement room sealing in two subspaces divides, can the pendulum movement of the pendulum segment by a guide means be guided be forcibly controlled in this way. Through the guide the movement of the pendulum segment is fixed relative to the housing, so that it is ensured that the pendulum segment is always along one of the two wall sections runs and thus its sealing function met to one of the two wall sections.

The guide means can, for example, as a guide element with a circular cross-section parallel to the plane of rotation of the rotary piston be formed, which has a radius RF = (RA - 2RZ), in the center of the second wall section is arranged on the housing and itself extends perpendicular to the plane of rotation of the rotary piston. The pendulum segment is designed so that the guide element with the pendulum segment works together and, for example, by a suitable shaping the pendulum segment causes the pendulum motion. In particular, that can guide means by engaging in the pendulum segment, the pendulum movement of Pendulum segments forcibly control, the pendulum segment to this Purpose may have a recess in its interior.

Furthermore It is conceivable that when the end sections of the curved side of the pendulum segment by means of rotatably arranged, a circular cross-section having facing sealing elements are formed, the guide element interacts with the sealing elements arranged on the pendulum segment and thereby the pendulum movement of the pendulum segment during the Rotation of the rotary piston leads.

The Contour in cross section parallel to the plane of rotation of the rotary piston of the first and second wall portion of the housing can by envelope circles are described with the radius RA, the centers of the the envelopes associated with the first and second wall sections spatial are arranged offset. The position of the centers of the two envelope circles relative to each other describe themselves by an angle about a pivot axis, wherein the position of the pivot axis in the cross-sectional plane parallel to the plane of rotation of the rotary piston through an intersection the two envelopes is defined. The angle representing the position of the first and second wall section describes each other, defines the form and also the working behavior the device. At an angle of 0 °, the cross section is parallel to the plane of rotation of the rotary piston of the housing circular, the outside of the closure element is always on the housing, and the displacement is during the rotation of the rotary piston about its axis of rotation not divided into subspaces, so no volume change the subspaces he follows. This corresponds to an idling of the device in which no volume change caused by the rotation of the rotary piston. Is the angle not equal to zero, so are the outside of the closure element during the rotation of the first wall portion and the end portions the curved one Side of the pendulum segment on the second wall portion of the housing. The displacement room becomes so in two subspaces shared while the rotation of the rotary piston in a differential manner increased and decreased become.

In a variant of the invention has the bordered by the housing displacer a constant volume that will not be changed during operation can. The housing shape is then by a constant angle between the first and second wall section descriptive envelopes defined. At a Another variant is in contrast to the displacement variable in its volume and can during the operation of the device changed become. about a volume change of the displacer can The relationship the volume of the subspaces adjusted to each other and thus the compression ratio of maximally compressed to maximally expanded volume of both subspaces of the Device to be determined.

Prefers the volume change takes place of the displacement room by a pivoting of the second wall section about the pivot axis, their position through the intersection of the two the cross section of the first and second wall sections in the plane of rotation is defined by the rotary piston descriptive envelopes. The Pivot axis is in the end of the first wall section and extends perpendicular to the plane of rotation of the rotary piston. By the pivoting of the second wall section relative to the first Wandungsabschnitt about the pivot axis, the volume of the displacement chamber changed and the compression ratio of maximum compressed to maximally expanded volume of the subspaces set become.

The geometric relationships the device can be by means of the contours of the components of the Rotary piston, the pendulum segment and the housing in the cross-sectional plane describe parallel to the plane of rotation. In particular, a variant the device through the radii RA, RI, RZ and RF and the positions the axis of rotation of the rotary piston, the pendulum segment axis and the Center point of the second Wandungsabschnitts completely described. It is conceivable that perpendicular to the plane of rotation, the geometric Change the dimensions of the arrangement. The positions of the axis of rotation and the pendulum segment axis have to but independently from the position relative to the plane of rotation, so that the rotary piston rotatable about the axis of rotation and the pendulum segment about the pendulum segment axis is pivotable. It is also conceivable that the radii are vertical Do not change to the rotation level and the arrangement by constant radii RA, RI, RZ and RF and a Height H is writable and up and / or down by trained by the housing Cover and / or the base plate is limited.

By definition, the longitudinal sectional views are perpendicular to the plane of rotation 111 a rotary piston 2 ( 2 ) while the cross-sectional views are parallel to the plane of rotation 111 of the rotary piston 2 are oriented. Out 1A to 1F respectively. 3A to 3F one obtains an overall view of the respective device by adding the individual, the upper, middle and lower part performing longitudinal sections on each other.

The movement of the device, in particular the nature of the pendulum motion of the pendulum segment 3 during the rotation of the rotary piston 2 around its axis of rotation 110 is based on 4A to 4G explained.

The device according to 1A to 1F and 2 has one in a housing 1 arranged rotary piston 2 on, one upper and one lower, parallel to the plane of rotation 111 of the rotary piston 2 extending base plate 21 . 21 ' which is about perpendicular to the plane of rotation 111 of the rotary piston 2 extending waves 210 . 210 ' and means for storage 10 rotatable in the area of the upper and lower part in the housing 1 are stored ( 1A . 1B and 1E . 1F ). Between the base plates 21 . 21 ' and is firmly connected to these in the region of the middle part of the device, as seen from 2 it can be seen, a closure element 22 arranged along with the upper and lower base plate 21 . 21 ' the rotary piston 2 formed. Also between the base plates 21 . 21 ' is a pendulum segment 3 above a perpendicular to the plane of rotation 111 of the rotary piston 2 between the base plates 21 . 21 ' extending pendulum segment axis 31 swiveling with the rotary piston 2 connected ( 1C . 1D and 2 ). The pendulum segment axis 31 can, for example, one between the base plates 21 . 21 ' be formed fixed axis about which the pendulum segment is pivotable.

The housing 1 The device forms in the region of the middle part of a displacement 6 out, by the rotary piston 2 and that on the rotary piston 2 arranged pendulum segment 3 in two subspaces 61 . 62 shared. The through the subspaces 61 . 62 trained displacement room 6 is in the rotation plane 111 through a first and a second wall section 11 . 12 bounded and becomes up and down in the direction perpendicular to the plane of rotation 111 through the upper and lower base plate 21 . 21 ' completed.

The rotary piston 2 is rotatable in the housing 1 arranged and rotated in operation about its axis of rotation 110 , By the rotational movement of the rotary piston 2 becomes the pendulum segment 3 placed in a pendulum motion, synchronous to the rotation of the rotary piston 2 expires, so that the period of the pendulum motion of the orbital period of the rotary piston 2 equivalent. The pendulum movement becomes the pendulum segment 3 to the second wall section 12 deflected and lies during the rotation of the rotary piston 2 around its axis of rotation 110 on the second wall section 12 at.

To the separation of the displacement 6 in two subspaces 61 . 62 to reach, the pendulum segment has 3 two sealing elements 32 . 33 on, which are cylindrical and about axes of rotation 321 . 331 rotatable on the pendulum segment 3 are arranged and one of which always on the second wall section 12 the housing rests laterally in a sealing manner. This is due to the pendulum motion of the pendulum segment 3 and the associated deflection of the pendulum segment 3 towards the second wall section 12 causes.

An embodiment of the device with measures for guiding the pendulum segment 3 is in 3A to 3F shown, which differs from the first embodiment according to 1A to 1F distinguishes that in the 3A and 3B illustrated upper part of the device as a fixed, the displacement 6 final cover of the housing 1 is formed, on which a trained in the middle part guide element 4 for guiding the pendulum movement of the pendulum segment 3 arranged and with the housing 1 is firmly connected. The middle part and the lower part of the device, shown in the 3C and 3D respectively. 3E and 3F , correspond substantially to the first embodiment according to 1C to 1F , wherein in the middle part additionally the guide element 4 over a recess 304 in the pendulum segment 3 in the pendulum segment 3 intervenes. With the guide element 4 will cause the pendulum motion of the pendulum segment 3 during the rotation of the rotary piston 2 is guided, the position of the pendulum segment 3 So by the guide element 4 constantly clearly defined, so as to ensure that a sealing element 32 . 33 of the pendulum segment 3 always on the second wall section 12 is applied.

The mode of action of the guide element 4 can be determined by 3D to explain. The guide element 4 is as a cylindrical component with a plane parallel to the plane of rotation 111 of the rotary piston 2 formed in a circular cross section and extending from that through the upper part of the device according to 3A and 3B formed lid of the housing 1 perpendicular to the plane of rotation 111 in the recess 304 in the pendulum segment 3 inside the pendulum segment 3 Such is that the guide element 4 at no time the pendulum segment 3 can touch. The guide element 4 works with those on the pendulum segment 3 arranged sealing elements 32 . 33 together and stands for the leadership of the pendulum segment 3 with one of the sealing elements 32 . 33 over the recess 304 in the pendulum segment 3 facing sides of the sealing element 32 . 33 in active connection. In the in 3D shown position of the rotary piston 2 lies the guide element 4 on the inside of the pendulum segment axis 31 seen from right sealing element 32 and thus causes the leadership of the sealing element 32 along the second housing section 12 ,

The operation and the movement of the device for compressing and / or displacing a fluid go out 4A to 4G in which the rotary piston 2 and that on the rotary piston 2 arranged pendulum segments 3 in different positions during the rotation of the rotary piston 2 around the axis of rotation 110 are shown. The in 4A to 4G The device shown here is the embodiment according to the 3A to 3F underlying, so that the pendulum motion of the pendulum segment by the guide element 4 during the rotation of the rotary piston is guided around the axis of rotation.

At the in 4A to 4G illustrated device, the entry and exit of the fluid to be displaced and / or to be compressed during operation by an inlet valve 51 or an outlet valve 52 , in the first and second wall section 11 . 12 are provided. The intake and exhaust valves 51 . 52 are not necessarily in the wall sections 11 . 12 The housing can also be located in the base plate 21 . 21 ' of the rotary piston 2 or the upper, a de ckel forming area of the housing 1 are located.

In the 4A to 4G shown sequence is a direction of rotation U of the rotary piston 2 in the clockwise direction, wherein in general the direction of rotation of the device is arbitrary selectable.

At a first time ( 4A ) is the pendulum segment 3 in a central position on the rotary piston 2 , is therefore symmetrical to the closure element 22 aligned. At this time is the displacement 6 completely through the first subspace 61 formed, the volume of the total volume of the displacement 6 corresponds and that through the second wall section 12 and the first two pages 301 . 302 of the pendulum segment 3 as well as those on the pendulum segment 3 arranged sealing elements 32 . 33 in the cross-sectional plane parallel to the plane of rotation 111 is limited laterally. Perpendicular to the plane of rotation, as from the 3A to 3F it can be seen, is the displacement 6 on one side by a base plate 21 and on the other side through one through the housing 1 finished lid. The closure element 22 lies with its outside 222 on the first wall section 11 of the housing 1 while the sealing elements 32 . 33 both at the opposite transition areas from the first wall section 11 to the second wall section 12 in the field of admission 51 and the exhaust valve 52 are arranged on the housing 1 issue.

At a second time ( 4B ) has the rotary piston 2 rotated in the direction of rotation U by an angle. The pendulum segment 3 is relative to the closure element 22 around the pendulum segment axis 31 pivoted, thereby causing the guide element 4 with the cylindrical sealing element 32 in operative connection and via the sealing element 32 the pendulum segment 3 deflects towards the second wall section, so that of the pendulum segment axis 31 from considered right sealing element 32 on the second wall section 12 is applied. Due to the interaction of guide element 4 and sealing element 32 becomes the deflection of the pendulum segment 3 positively controlled and the sealing end between the sealing element 32 and second wall section 12 guaranteed. Between the closure element 22 and the right seal member 32 is in the range of the inlet valve 51 a second subspace 62 emerged. As the total volume of the through the first and second subspace 61 . 62 formed displacer 6 is constant, is the volume increase of the second subspace 62 inevitably with a volume decrease of the first subspace 61 connected. The first subspace 61 is always by a wall section 11 . 12 , the first and second page 301 . 302 of the pendulum segment 3 as well as the inside 221 of the closure element 22 limited, while the second subspace 62 always between the second wall section 12 , the outside of the closure element 22 and the curved side 303 of the pendulum segment 3 is formed. By reducing the size of the first subspace 61 , caused by the rotational movement of the rotary piston 2 from the position according to 4A towards the position in 4B , a fluid is in the first compartment 61 so displaced or, if the exhaust valve 52 closed, condensed. At the same time, the increase in volume of the second subspace 62 a fluid through the inlet valve 51 in the second subspace 62 moved in.

At a third and fourth time ( 4C and 4D ) has the rotary piston 2 further rotated in the direction of rotation U, and the volume of the second subspace 62 has been at the expense of the volume of the first subspace 61 increased. The sealing element 32 lies continuously on the second wall section 12 on, effected by the leadership of the guide element 4 , and sets the seal between the first and second subspace 61 . 62 ago.

At a fifth time ( 4E ) has the rotary piston 2 relative to the position in 4A rotated in the direction of rotation U by 180 °. In this position is the volume of the first subspace 61 minimal, while the volume of the second subspace 62 is maximum. The closure element 22 is at this time the second wall section 12 facing, the pendulum segment 3 is in a central position on the rotary piston 2 and points with its pendulum segment axis 31 to the first wall section 11 ,

During the further rotation of the rotary piston 2 ( 4F and 4G ) becomes the second subspace 62 reduced so that one in the second subspace 62 befindliches fluid is compressed. The guide element 4 now acts on the left seen from the pendulum segment of the left sealing element 33 and in turn causes a deflection of the pendulum segment 3 towards the second wall section 12 of the housing so that the sealing element 33 on the second wall section 12 abuts and causes a seal.

The periodic rotation now continues with the state according to 4A , At transition from the state according to 4G according to the condition 4A becomes the volume of the second subspace 62 doing so by the rotational movement of the rotary piston 2 reduced to a minimum residual volume, so that one in the second subspace 62 located fluid undergoes a very large compression.

The volume change of the first subspace 61 during the rotation of the rotary piston 2 around the axis of rotation 110 is relatively low and describable by the ratio of maximum volumes (see 4A ) to minimal volume (see 4E ) of the first subspace 61 , The compression of one in the subspace 61 located fluid is thus also relatively low. The second subspace 62 whereas, during the rotation of the rotary piston 2 around its axis of rotation 110 a volume change from a minimum residual volume ( 4A ) up to a maximum volume ( 4E ) and again to the minimum residual volume, so that one in the second subspace 62 fluid during the rotation of the rotary piston 2 a large compression or expansion experiences. That about the change in volume of the second subspace 62 achievable compression ratio is so large, but practically limited by the compressibility of the fluid and a minimum residual volume of the second subspace 62 ,

The pendulum motion of the pendulum segment 3 is during the rotation of the rotary piston 2 around its axis of rotation 110 through the guide element 4 guided and thus force-controlled. Through the guide element 4 Ensures that a sealing element 32 . 33 always on a wall section 11 . 12 is applied to the sealing division of the displacement 6 into its two subspaces 61 . 62 to effect. The pendulum motion of the pendulum segment 3 is thereby by the during the rotation of the rotary piston 2 prevailing physical forces on the pendulum segment 3 supported, so that caused by the rotational movement caused by the centrifugal forces an additional contact pressure of the sealing elements 32 . 33 on the respective wall section 11 . 12 is produced.

5 illustrates the geometric design of the individual parts of the rotary piston 2 and the pendulum segment 3 according to the in 3A to 3F illustrated second embodiment in a plan view of the rotary piston 2 and that on the rotary piston 2 arranged pendulum segment 3 ,

On the base plate 21 of the rotary piston 2 on the one hand is the closure element 22 arranged and firmly connected to this and the other on the pendulum segment axis 31 the pendulum segment 3 pivoted. The closure element 22 has in cross section parallel to the plane of rotation 111 of the rotary piston 2 a crescent shape and has an inside 221 passing through an inner radius RI around the pendulum segment axis 31 is writable, and an outside 222 passing through an outer radius RA about the axis of rotation 110 of the rotary piston 2 is writable on. The closure element 22 extends as if from 1D and 3D visible, perpendicular to the plane of rotation 111 over the height of the middle part of the device.

That on the base plate 21 arranged pendulum segment 3 is parallel to the plane of rotation in cross section 111 essentially through three sides 301 . 302 . 303 limited, of which the first two pages 301 . 302 at an angle of approximately 90 ° to each other and in the connecting region of the pendulum segment axis 31 , which are perpendicular to the plane of rotation 111 extends, is arranged. The third page 303 of the pendulum segment 3 is curved and is writable by the inner radius RI about the pendulum segment axis 31 , The third pendulum segment side 303 nestles in its shape of the inside 221 of the closure element 22 so that the pendulum segment 3 in a pendulum motion around the pendulum segment axis 31 with his third page 303 along the inside 221 of the closure element 22 runs and forms a sealing transition. The pendulum segment axis 31 is at a distance D from the axis of rotation 110 of the rotary piston 2 staggered.

The pendulum segment 3 extends as in 1D and 3D can be seen, perpendicular to the plane of rotation 111 over the height of the middle part of the device, so over the entire displacement 6 and is through the upper and lower base plate 21 . 21 ' according to 1A to 1F or through the lower base plate 21 and through the case 1 formed lid according to 3A to 3F limited. The pendulum segment 3 seals the subspaces 61 . 62 of the displacement room 6 relative to each other, but can, in particular using suitable lubricants, relative to the upper and lower base plate 21 . 21 ' and along the case 1 move smoothly.

At the pendulum segment 3 are the two cylindrical sealing elements 32 . 33 arranged around the axes of rotation 321 . 331 are rotatably mounted, have a circular cross section with a radius RZ and over the height of the formed in the middle part of the device displacement 6 extend (see 1C and 3C ). The axes of rotation 321 . 331 the sealing elements 32 . 33 are in the cross-sectional plane parallel to the plane of rotation 111 arranged so that the distance between the axes of rotation in the cross-sectional plane parallel to the plane of rotation 111 2RA - 2RZ is one and the two axes of rotation 321 . 331 interconnecting line at an undeflected pendulum segment position 3 , so at the center of the rotary piston 2 positioned pendulum segment 3 , through the axis of rotation 110 of the rotary piston 2 runs and at the same time perpendicular to the pendulum segment axis 31 and the rotation axis 114 pointing symmetry axis of the rotary piston 2 stands. The maximum distance between the outer sides of the sealing elements 32 . 33 along the axes of rotation 321 . 331 connecting line in this case is 2RA.

The guide element 4 that in the in 3A to 3F illustrated embodiment for guiding the pendulum movement of the pendulum segment 3 serves, is on the housing 1 arranged and extends into the recess 304 in the pendulum segment 3 , has a cylindrical shape with a circular cross-section with the radius RF = RA - 2RZ and extends with its longitudinal axis perpendicular to the plane of rotation 111 , The longitudinal axis of the guide element 4 is in the cross-sectional plane parallel to the plane of rotation 111 in the centre 120 of the second wall section 12 of the housing 1 arranged so that the guide element 4 so concentric with the second wall section 12 is aligned. The shape of the recess 304 in the pendulum segment 3 is due to the realizable leadership of the pendulum segment 3 specified. In the in 3A to 3F Shown embodiment, there is an interaction between pendulum segment 3 and guide element 4 exclusively via the sealing elements 32 . 33 by the guide element 4 with at least one of the cylindrical sealing elements 32 . 33 interacts and is in contact. A direct contact between pendulum segment 3 and guide element 4 is to be avoided in this case, and accordingly, the shape of the recess 304 in the pendulum segment 3 to choose. In the in 3A to 3F the embodiment shown is the contour of the recess 304 in cross-section parallel to the plane of rotation 111 circular, describable by a sufficiently large radius around a point passing through the intersection of the two axes of rotation 321 . 331 connecting line with that through the pendulum segment axis 31 extending symmetry axis of the pendulum segment 3 is defined. It is also conceivable, instead of the sealing elements 32 . 33 an integrally formed pendulum segment 3 to use, in which the sealing elements 32 . 33 in the pendulum segment 3 are integrated and the guide element 4 directly to the inside of the recess 304 interacts.

In 6 is the shape of the displacer 6 forming housing 1 in cross-section parallel to the plane of rotation 111 shown. The inner contour of the housing 1 that the displacement room 6 describes can be described by two pitch circles with the radius RA, each a wall section 11 . 12 assigned. The center of the first circle, its left area in 6 the first wall section 11 represents, corresponds to the position of the axis of rotation 110 of the rotary piston 2 so that the closure element 22 of the rotary piston 2 whose outside 222 also by the radius RA around the axis of rotation 110 is writable, so with its outside 222 along the first wall section 11 runs and hugs this tightly. The middle-point 120 of the second pitch circle, whose right area the second wall portion 12 is from the axis of rotation 110 of the rotary piston 2 staggered. The spatial arrangement of the two pitch circles can be characterized by an angle α between two by a pivot axis 130 and one each of the centers 110 . 120 the sub-circles pointing lines is formed.

The two wall sections 11 . 12 of the housing 1 that the displacement room 6 in cross-section parallel to the plane of rotation 111 of the rotary piston 2 limit laterally and are described by the two subcircles, so are arranged eccentrically. The rotary piston 2 turns around the axis of rotation 110 in the center of the first wall section 11 while the guide element 4 in the centre 120 of the second wall section 12 is positioned. As the guide element 4 with the cylindrical sealing elements 32 . 33 interacts, the guiding element 4 and the sealing elements 32 . 33 in cross-section parallel to the plane of rotation 111 of the rotary piston 2 have a circular contour with the radius RF = RA - 2RZ or the radius RZ, wherein the axes of rotation 321 . 331 the sealing elements 32 . 33 spatially offset on the pendulum segment 3 are arranged (see 5 ), and the sealing elements 32 . 33 during the rotation of the rotary piston 2 around the axis of rotation 110 with the pendulum segment arranged thereon 3 inevitably the guide element 4 on his second wall section 12 must pass side facing, directs the guide element 4 the pendulum segment 3 about on the pendulum segment 3 arranged sealing elements 32 . 33 to the second wall section 12 out and thus leads the sealing elements 32 . 33 sealing at the second wall portion 12 along. By the opposite arrangement of the sealing elements 32 . 33 on the pendulum segment 3 lies one of the two sealing elements 32 . 33 always on the second wall section 12 and provides a sealing transition between pendulum segment 3 and second wall section 12 ago.

The device according to 1 to 6 is suitable for a variety of applications. For example, the device can be used as a pump, which according to the in 4A to 4G shown drain a fluid through the inlet valve 51 alternately in the first and second subspace 61 . 62 sucked in and out of the exhaust valve 52 ejects. Likewise, a use as an internal combustion engine is conceivable. For this purpose, fuel in the second subspace 62 compressed fluid (see 4G ) are injected and ignited, whereby an expansion of the fluid in the subspace 62 which causes a force on the closure element 22 exercises and in this way the rotation piston 2 put in a rotary motion. Due to the high achievable compression ratios caused by the volume change of the subspaces 61 . 62 of the displacement room 6 , in particular of the second subspace 62 from a maximum volume to a residual residual volume and again to the maximum volume, interpretations as a diesel engine with auto-ignition are just as conceivable as gasoline engines.

The compression and displacement ratios achievable by the device can be described by means of the two partial circles and by the first and second wall sections 11 . 12 limited housing shape and by the housing enclosed by the displacement chamber 6 certainly. 7A to 7C show different embodiments of the device with different displacement chamber sizes, by different arrangements of the displacement 6 enclosing wall sections 11 . 12 are determined relative to each other. In particular, in 7A to 7C the second wall section 12 in different position relative to the pivot axis 130 arranged. It is conceivable that the second wall section 12 variable and in operation around the pivot axis 130 is pivotable and thus the volume of the displacer 6 . 61 . 62 is adjustable during operation or that the second wall section 12 stationary relative to the first wall section 11 is arranged.

At the in 7A The arrangement shown is the second wall section 12 relative to the first wall section 11 around the pivot axis 130 pivoted on the end point of the first wall portion by an angle of 12.5 °. This results in a large maximum volume of the second subspace 62 and thus a high achievable compression ratio.

At the in 7B shown arrangement, the pivot angle of the second 12 first 11 Wandungsabschnitt a size of 7 °, the maximum volume of the second compartment and the thus achievable compression ratio are therefore smaller.

At the in 7C The arrangement shown is the pivot angle 0 °. In this case, it forms during the rotation of the rotary piston 2 around its axis of rotation 110 no second subspace 62 out, and the first subspace 61 experiences no volume change. This case corresponds to an idling of the assembly in which no work is done to displace or compress a fluid.

It is conceivable that the achievable compression and displacement ratios during operation via the arrangement of the wall sections 11 . 12 of the housing 1 adjust. 8th shows a longitudinal section through an arrangement with a displacement chamber 6 . 61 . 62 , Its volume by pivoting the second wall portion 12 around the pivot axis 130 is changeable. The arrangement has a lower part and a central part, which correspond to the in 3C to 3F correspond arrangements shown. To set the displacement volume, the upper part of the arrangement has a in the housing 1 enclosed piston top plate 41 on that with the guide element 4 and the second wall portion 12 firmly connected and over one with a lever 42 and a vertical connector 43 cooperating adjusting lever 44 around the pivot axis 130 can be pivoted. By pivoting the piston top plate 41 around the pivot axis 130 (please refer 7A to 7C ) become the second wall section 12 and the guide element 4 that with the piston top plate 41 are firmly connected, also pivoted, so that there is a change in volume of the displacement 6 . 61 . 62 passing through the first and second wall sections 11 . 12 is limited results. During the pivoting process, the guide element remains 4 always in the focus 120 of the second wall section 12 (Please refer 6 ), so that a volume change of the displacement 6 . 61 . 62 while maintaining the leadership of the pendulum segment movement by the guide element 4 given is.

9 shows an embodiment of an internal combustion engine, the two devices 700 . 700 ' that has a shaft 701 are interconnected and of which the first 700 for compressing the fluid and the second 700 ' for generating the torque. During operation of the internal combustion engine, the fluid is introduced into the first device via an inlet pipe 700 sucked in, compressed in the device and in a compressed state via a channel 710 in an antechamber 711 directed. The supply of the compressed fluid is via two valves 740 . 741 controlled. Into that in the antechamber 711 located, compressed fluid is via an injection nozzle 720 Fuel injected and with a spark plug 730 inflamed. By burning the mixture of compressed fluid and fuel, the fluid expands and drives the second device 700 ' on, by the rotary piston 2 the second device 700 ' and thus the wave 701 on which the rotary pistons 2 both the first and the second device 700 . 700 ' are arranged to be placed in a rotary motion. Per revolution of the rotary piston 2 around its axis of rotation, concentric with the shaft 701 runs once, the process runs once, with the compression and the torque generation exclusively in the second subspace 62 of the displacement room 6 the first or second device 700 . 700 ' done because in the second subspace 62 a greater compaction achievable is and the compression ratios in the first and second subspace 61 . 62 fundamentally different. The output can be over the shaft 701 take place, in particular either via an outside of the shaft 701 arranged output or via a provided between the two devices internal output 760 ,

The structure of the device with its components, in particular the rotary piston 2 , the pendulum segment 3 and the housing 1 The materials to be used depend on the field of application and the forces and pressures that occur. For internal combustion engines, for example, it is generally possible to use materials which are also used in other types of engine, ie in particular steel or suitable metal alloys having the required strength properties. For smooth operation and to reduce friction losses and abrasion, suitable lubricants can be used during operation, which enable smooth and low-wear operation.

The applications the device are not on the embodiments described here limited. For example, a torque converter using the device may for different ones Vehicle types are used, in particular as a transmission or as hydraulic power transmission devices for motor vehicles, but also for example as a power transmission device for bicycles or other means of locomotion, in which a generated torque transmit a drive medium becomes.
