Description

METHOOD OF TRANSFORMING ENERGY IN A ROTARY SCREW MACHINE OF VOLUMETRIC TYPE}

The present invention relates to a method of converting energy in a rotary propeller.

Volume screw machines of rotary type include a female (enclosing) propulsion element and a number (enclosing) propulsion element, which constitute a conjugated screw element. The female propulsion element has an inner contour surface (inner propulsion surface, female surface) and the male propulsion element has an outer contour surface (outer propulsion surface, male surface). The screw surface is non-cylindrical, restricting the element radially. The elements are parallel and are separated by a length E (eccentric distance), centering on an axis which generally does not occupy the same space.

Three-dimensional rotary propellers of this type are described in US Pat. No. 5,439,359, wherein a male element surrounded by a fixed arm element makes planetary motion with respect to the arm element.

The working chamber of the internally coupled rotary volume propeller is formed by kinematic mechanisms consisting of the elements of the male and female curves.

The motion transformation is based on the rotational movement of interconnected male and female elements, which make mechanical curvilinear contact with each other and perform axial movement when making relative movement between paired elements in space. Create closed working chambers for the object.

In most cases, the propelling surface is in the form of a circle (cone), as in the examples known from French patent application FR-A-997957 and US Pat. No. 3,975,120. The description of kinetic transformations when used in motors is described in V. Tiraspolskyi's "Drilling, Hydraulic Downhole Motors" drill process, published in TECHNIP in Paris, France. in Drilling "(see pages 258-259).

The effectiveness of the method of converting energy in prior art propellers is judged by the strength of the thermodynamic treatment occurring in the propellers and is characterized by the general parameter "angular cycle". The cycle is equal to the turn angle of the rotational motion element (female, male or tuning link) selected as an element with an independent degree of freedom.

The angular cycle is a period in which a total change (open and closed) period of the cross sectional area of the work chamber formed by the male and female elements occurs, and the period in which the propeller has an internal propulsion surface with respect to the period of work P _f in the external propeller surface. (P _m ) is equal to the switching angle of the member with independent degrees of freedom, in which the axial movement of the work chamber occurs.

The conventional method of converting energy in a rotary volume propeller with curved paired elements realized in similar volume propellers has the following drawbacks.

Limiting the mechanical potential energy due to incomplete handling of the systemic movement, thereby not increasing the amount of angular cycles per one turn of the driving member with independent degrees of freedom;

Limiting the specific power of the similar propeller;

-Efficiency limitation;

-Reaction in the fixed body of the propeller.

In all cases, the longitudinal axis of the inner conjugate propulsion element is parallel. Sometimes the element has eccentricity, some of which is operable. Planetary motion or differential motion is provided.

The object of the present invention is to solve the above-mentioned problem.

The volume propeller used in the present invention includes at least two sets of paired male and female elements spaced apart from each other along the central axis of the propeller. Each set of female elements has an inner profiled surface about the first longitudinal axis and each set of male elements has an outer profiled surface about the second longitudinal axis. The first and second longitudinal axes are parallel to each other. The male element is located in the cavity of the corresponding female element.

The method of converting energy in the rotary propeller according to the invention is such that the working chamber formed between the female element and the male element has an axial motion when the female and / or the male element rotates. In the present invention, different sets of rotational movements include angular periods in which the synchronous and inphase motions of the elements in the different sets differ from each other in oscillation of the axial motion of the laboratory. It happens simultaneously in a way that is carried out with the value of.

That is, the component (or element) of the propeller is characterized by the fact that when one pair of coupling elements is operated, the coaxial longitudinal axis in each set is determined according to a predetermined ratio (ratio of one element to another). Arranged in such a way that they move with the angular velocity of the values.

The synchronization helps to optimize the function of the propeller.

In a preferred embodiment of the present invention, each cycle decreases from one set to the next, having a compressed working medium. In another embodiment, each cycle increases from one set to the next, having an inflation working medium.

The propeller includes both a rotor and a contrarotor, the half-rotor rotating in a direction opposite to the direction of rotation of the rotor. Between the rotor and the half-rotor a planetary element is installed. In this embodiment, stable and balanced operation of the working medium in the working room is facilitated.

As a coupling means, a mechanical device can be used. Alternatively, the working medium may be used to join another set. In the case of combining the selection means, the means for synchronizing comprises (at least partially) a hollow shaft, the working medium passing through the shaft.

In another preferred embodiment, there is a first set of forming a differential motion mechanism having three degrees of freedom of independent two-degrees of mechanical rotation, and a second motion forming planetary movement mechanism having two degrees of freedom of mechanical rotations of one degree of freedom. Use two sets. The third set of conjugated elements can form a differential motion mechanism.

The thrusters are arranged in such a way that the first and third sets of paired coupling elements have essentially the same cross section. That is, the first and third sets are of the same design and are joined by the second set. In particular, the average radius and / or thickness of the propulsion element and the relief of the surface are the same.

The set includes, of course, at least one male and one female element. In a preferred embodiment, the set is installed in a nested structure. For example, the first and second sets described above may include two groups of conjugated male and female elements separated by channels through which a working medium may be conveyed.

In another preferred embodiment of the method according to the invention, the heat energy of the working medium is transferred and supplied to a heat exchanger (moved from the working medium in the first stage, supplied in the second stage or otherwise circulated).

In addition, the mechanical energy generated in one of the sets can be used to drive other mechanical devices. In other words, mechanical energy can be derived from the rotary propeller. Of course, well known thermodynamic laws must be taken into account, in particular temperature changes will occur simultaneously in any part or working medium of the propeller.

The volume propeller used in the present invention shown in Figs. 1A and 1B includes three different sets of paired elements. That is, the first set 1 is formed by a differential kinematic mechanism that inhales and compresses air, and the second set 2 is a planetary mechanism that compresses air (and provides fuel combustion to the work room 140). And the third set 3 is formed with a differential kinematic mechanism that expands the combustion product from the work chamber 140 of the second set 2.

In other words, the volume propeller used in the invention is a rotational propulsion type in which movement is transformed and a continuous-cyclic change in the energy of the workpiece occurs simultaneously as the workpiece passes through the chamber in another section. Rotary screw internal combustion. Thus, the volume propeller generates work object energy. The volume propeller is provided with a synchronization device 11, 14 to support the operation of the set 1, 3. The synchronization device is provided as a single element as shown in FIG. 1B.

Note that the sets 1, 2, 3 of the volume propellers according to the invention are different and are spaced apart from each other along the center axis Z of the propeller. In other words, the sets 1, 2 and 3 are not surrounded by each other. The sets 1, 2 and 3 are not enclosed but rather one set behind one front set or in line with one front set. The sets are all about the central axis of the propeller.

The different sets are coupled by the action of mechanical links and gaseous workpieces, for example gas links. In the mechanical link between the mechanisms 1, 2, 3 provided by the common shaft 4 which is partially hollow, a crank 10 is attached to the shaft. Air passes from the set of mechanisms 1 to the set of mechanisms 2 through the hollow portion of the shaft 4. The sets 1 and 2 together form a volumetric rotary propulsion compressor. The set 2 provides a combustion chamber 140 and the sets 2 and 3 interact with each other to form a volumetric rotary expansion propeller (detander).

The first and second sets (1,3) are two groups of conjugated elements, i.e. elements of the first group (5,6,7; 5'6'7 ') and elements of the second group (15,16). , 17; 15'16'17 ').

It is noted here that the first set 1 and the second set 3 have basically the same shape, for example the same cross section. This is especially true with one propulsion element. The propulsion elements have the same average radius and the same thickness.

The details are as follows:

The first set comprises first arm elements 5, 15 with internally shaped surfaces 105, 115, respectively, wherein the arm elements 5, 15 are centered on a fixed axis Z which is the axis of symmetry of the volume propeller. It is done. The arm elements 5, 15 have a symmetric order of six. The concept of symmetry order mentioned below is understood as the rotational symmetry of the end face of the element. The first set additionally includes second elements 6, 16 with both male and female, for example with external trochoidal surfaces 216, 116 and internal trocoid surfaces 206, 106. The element has a symmetric order of 5 and is centered around its axis (0 ₆ , 0 ₁₆ ). These are planetary motions. There are additionally provided synchronization elements 7, 17 with externally shaped surfaces 207, 217 with four symmetric orders, respectively. Between the elements, work rooms 100 and 300 are provided on one side and work rooms 200 and 400 on the other. A channel is installed between the elements 5, 6, 7 on one side and the elements 15, 16, 17 on the other side, so that the air delivered to the work room 100, 200 is lower side of the volume propeller (FIG. 1). Is returned to the work room 300,400.

The second set 2 comprises only two conjugated elements. In other words, the female element 8 has an inner shape plane 108 with three symmetric orders about the axis Z and the male element has an outer shape trocoid plane 209 with a symmetric order of two. It performs planetary motion around the axis (0 ₉ ). The working room 140 is formed between the elements. Fuel is injected into the work chamber 140 via the inlet 12.

The third set 3 has, in each group, a first numerical element 7 ', 17 having an outer surface 207', 217 ', with a symmetrical order of four, around a fixed axis Z. Contains'). The second element 6 ', 16' with both male and female include initial trocoid planes 106 ', 206': 116 ', 216', both having a symmetric order of five. The elements 6 ', 16' are centered on the second axis 06 ', 016' and are in planetary motion. Elements 5 ', 15' with internally shaped surfaces 105 ', 115' with a symmetric order of 6 act as synchronization-elements. Between the elements, work rooms 100 ', 300' are formed on one side and work rooms 200 ', 400' on the other.

The set 1 shown in FIG. 1 forming the differential mechanism has three degrees of freedom of mechanical rotation of the elements 5, 6, 7; 15, 16, 17. The two degrees of freedom is an independent degree of freedom of one revolution.

The same applies to the elements 5 ', 6', 7 '; 15', 16 ', 17' of the set 3 which form such a differential mechanism.

The planetary kinematic mechanism for converting the motion of the set 2 shown in FIG. 1 has two degrees of freedom of mechanical rotation of the element 9. The 1 degree of freedom is an independent degree of freedom of one revolution.

In the present invention, the energy conversion is the operation of the conjugate elements forming the mechanical coupling action of the elements in the set of groups of kinematic mechanisms, ie the conjugate elements arranged coaxially eccentrically in the internal cavities of each other 5, 6, 7, 15, 16, 17, 8, and 9 are realized by converting the operation formed by. In addition, the synchronous coupling link 10 is used as does a corresponding device in which an element performs a synchronous interconnection operation about the main axis and the magnetic axis of the device. In order to do this, the motion conversion is carried out simultaneously in at least two groups of kinematic mechanisms, the motions of the conjugate elements of each other being converted to receive the workpiece energy.

As the workpieces pass through the differential kinematic mechanism in set 1, which are mechanically connected to each other as shown in Fig. 1 and for example form a suction and compression zone, the method according to the invention is synchronized And facilitating implementation of motion conversion of the simultaneous conjugated element. At least, this differential kinematic mechanism formed in set 1 has three degrees of freedom of one mechanical rotation, of which two degrees of freedom are independent, and the planetary kinematic mechanism of set 2 shown in FIG. It includes the compression and exhaust sections of the workpiece with one independent degree of freedom. In differential and planetary mechanisms, when calculated with the switching angle of the output link 4, different angular period values of the axial motion of the workroom are given.

Note that the propulsion element cannot be in an arbitrarily shape, but it must be in a shape with good properties. The preferred shape d _m of the propulsion element is configured in the manner as shown in Fig. 4 in which the shape d _m has a symmetric order of n _m = 5.

The shape begins with the structure of a hypocycloid (Γ) with a parametric form (dependent on the parameter t).

x (t) = E cos (n _m -1) t + E (n _m -1) cos t

y (t) = E sin (n _m -1) tE (n _m -1) sin t

The hypocycloid (Γ) of symmetric orders n _m , (n _m +1), (n _m +2) ... (n _m + i) is a curve, the curve is a radius O _1A = E and a center O _{E m} , E (n _m +1), E (n _m +2) ... E (n) with center O _m , described as one point A of the circle with _E and as shown in FIG. along the inner face of another circle with the same radius as _m + i). The point where point A is in contact with the circle is indicated by B, C, D, F, I. The equivalent way constituting the hypocycloid (Γ) of symmetric orders n _m , (n _m +1), (n _m +2) ... (n _m + i) is based on the curves described above , A curve with the center (O ₂ ) and the point (A) of a circle of radius E (n _m -1), E (n _m +1) ... E (n _m + 1 + i) is given by En _m , E (n _m +1), E (n _m +2) ... is a curve that is wound without sliding along the inner face of a circle with the same radius as E (n _m + 2 + i).

The shape D _m used for the propulsion element in the present invention starts at the hypocycloid (Γ), along the hypocycloid, for example in FIG. 4 with a radius r ₀ such as 2E, r ₀ = FR = 2E _. Is obtained by winding a circle, wherein during winding, the center of the circle moves along the hypocycloid.

If r ₀ is chosen to vary unilinearly along the Z axis (vertical axis to the plane in Fig. 1), then shape D _m is found and the parametric equation (depending on the parameter t) is:

x (t) = E <cos [(n / (n + 1) [arcsin (sin t) -t]] + n cos [(arcsin (sin t) -t) / (n + 1)]> + r ₀ (z) cos [arcsin (sin t)-(arcsin (sin t) -t) / (n + 1)];

y (t) = E <sin [(n / (n + 1) [arcsin (sin t) -t]] + n sin [(arcsin (sin t) -t) / (n + 1)]> + r ₀ (z) sin [arcsin (sin t)-(arcsin (sin t) -t) / (n + 1)];

Where n = n _m −1 or n = n _f −1.

5 shows a three-dimensional shape of the propulsion element obtained using the structural formula described above.

All of the outer surfaces (217,216,207,206,217 ', 216', 207 ', 206', 209) of the male elements 17,16,7,6,17 ', 16', 7 ', 6', 9 and the female elements 5 All of the inner surfaces 105, 106, 115, 116, 105 ', 106', 115 ', 116', 108 of 6,15,16,5 ', 6', 15 ', 16', 8 are as described above. It is constrained radially by the non-cylindrical propelling surface of the configuration. Note that the symmetrical order of the face increases from indoors to outdoors. In the second set, the propulsion element 9 has a bisymmetrical order, while the propulsion element 8 has a trisymmetrical order. In the first set 1 and the third set 3, the innermost elements 17, 17 ′ have elements of four symmetry and themselves have elements 15, 115 ′ of internally shaped faces 115, 115 ′. Is surrounded by elements 16, 16 'of a 5 symmetric order surrounded by. This series of symmetric orders is repeated with elements 5,5 'starting at element 7,7'.

The elements 5, 7, 15, 17, 5 ′, 7 ′, 15 ′, 17 ′ are set such that they can rotate about the axis Z. The axes O ₆ , O ₁₆ , O _{6 ′} , O _{16 ′} , O _{9 of} the elements ₆ , ₁₆ , _{6 ′} , _{16 ′} , ₉ are each movable. The axis O ₆ has an eccentric distance E ₁ = E with respect to the center axis Z, and the axis O ₁₆ has an eccentric distance of -E ₂ (less than E ₁ ) with respect to the center axis Z. Be careful. The axis O ₆ , 0 ₁₆ is arranged in a line crossing the central axis. During rotation, spatial correlation is maintained. In other words, if the eccentricity is chosen in such a way as to obtain a statically balanced volume propeller, the propeller is also dynamically balanced. The elements 6, 16, 9 are set in the propeller such that they can carry out planetary motion about the axis Z. The elements 6, 16, 6 ', 16' are set between the elements 5, 7, 15, 17, 5 ', 7', 15 '17' without additional means, respectively, to start the planetary motion of the rotor. do. The rotor 9 is hinged to the crank 10 of the shaft 4.

In the differential mechanism (1,3) and the planetary mechanism (2), the suction due to the compression in the set (1), the compression due to the release of the workpiece within the work chamber 140 of the set (2), and the set (3) The link is set up such that the expansion of the working object and the work room 100 ', 200', 300 ', 400' takes place in a continuous-circulating manner. The combustion section with the combustion chamber 140 is formed by the elements of the planetary mechanism 2, the cross section of the planetary mechanism being as shown in FIG. The planetary mechanism 2 consists of a centrally fixed stator 8, a planetary rotor-satellite 9 and a crank 10 in the shaft 4. The device 12 injects fuel into the combustion chamber 140 and ignites the injection. The combustion chamber 140 is formed of one cycle of two twists of the shape of the elements 8 and 9 or two cycles of twist (for fuel combustion at a constant volume).

Together with the stationary element 8, the planetary motion of the element 9 is defined by the following parameters.

ω _{8 =} 0, symmetric order n ₈ = 3; n ₉ = 2; ω ₁ = ω _{rotational motion 9} = 1; ω ₉ = ω _{Swing operation (9)} = -0.5

The total volume in the set 2 is given by V ₂ = (3V ₁₄₀ 360/360) = 3V ₁₄₀ for the shaft 4 rotation. In each set, the arm propulsion element 8 is rotated about the central axis. Optionally, the element 8 can be fixed. The planetary motion of the male propulsion element 9 coupled with the first element is carried out with the aid of a synchronous coupling link-crank 10 or a third (male) coupling which is coaxial with the first set. Implemented with the help of the propulsion elements

In the first set, three types of states can be selected from the elements 5, 6 and 7 of the first group.

a) rotation (or non-rotation) of the first element 5 with respect to the central fixation axis and rotation (or non-rotation state) of the third element (tuning) with respect to the central fixation axis,

b) rotation of the axis 0 ₆ of the second element 6 with respect to the fixed center axis, and

c) Swivelling of the second element 6 with the aid of a synchronous coupling link (several propulsion elements 7 coupled coaxially with the first element).

The three states include the following and are mechanically synchronized with each one of the elements 15, 16 and 17 of the second group of the first set 1, respectively.

d) rotation (or non-rotation) of the first element 15 with respect to the central fixed axis and rotation of the third element (tuning) 17 with respect to the central fixed axis,

e) rotation of the axis 0 ₁₆ of the second element 16 with respect to the fixed center axis, and

f) pivoting of the second element 16.

The equation for the angular cycle (Ti) of a pair of female-male pairs is:

Where: ω _f , ω _m -is the angular velocity of the male and female elements about their center;

ω _i -an angular velocity of an independent element, for example an element that implements a revolution and turn angle defined by a value of Ti;

n _{m , f} -symmetric order, n _{m , f} for the hypotherochoid method with external enclosure; And

n _f is for epipitoid method with internal envelope.

The differential motion in set 1 (including the rotation of the elements 15, 15: 17, 17 and the planetary motion of the elements 6, 16) is defined by the following parameters:

ω _{ro (5,15)} = 1; ω _{ro (7,17)} = -1; (ω _{ro (7,17)} -ω _{re (6,16)} ) / (ω _{ro (5,15)} -ω _{re (6,16)} ) = n _{5 , 15} / n _{7 , 17} and ω _{re (0-6), (0-16)} = (ω _{ro (5,15)} n _5,15 -ω _{ro (7,17)} n _7,17 ) / (n _{5 , 15} / n _{7 , 17} ) = (6 + 4) / (6-4) = 5; (ω _{s (6,16)} -ω _{re (6,16)} ) / (ω _{ro (5,15)} - ω _{re (6,16)} ) = n _{5 , 15} / n _{6 , 16} and ω _{m (6,16)} = ω _{s (6,16)} = (ω _{ro (5,15)} -ω _{re (6,16 )} ) (n _{5 , 15} / n _{6 , 16} ) + ω _{re (6,16)} = (1-5) (6/5) + 5 = 0.2

The total volume of the studio (100 300) that controls the rotation of the shaft 4 is represented by _{V T (100) = 6V 100} 360/90 = 24V 100 and _{V T (300) = 6V 300} 360/90 = 24V 300.

While the shaft 4 is rotating, the total volume of the chambers 200,400 is represented by V _{T 200} = 5V ₂₀₀ 360/75 = 24V ₂₀₀ and V _{T 300} = 5V ₃₀₀ 360/75 = 24V ₃₀₀ .

Returning to the third set 3, the differential movement of the fixed elements 7 ′, 17 ′, the elements 5, 15 ′ according to the angular velocity given by the reducer 18 in the shaft 4 (independent operation) or Note that the rotation of 5 'and 15' and the planetary motion of the elements 6 'and 16' are defined by the following parameters:

ω _{5 ', 15'} = ω _{ro (5 ', 15')} = 1/3; ω _{ro (7 ', 17')} = 0; ω _{re (0-6 ', 0-16')} = (ω _{ro (5 ', 15')} n _{5 ', 15'} ) / (n _{5 ' , 15'} -n _{7 ', 17'} ) = 2 / (6-4) = 1, and ω _{s (6 ', 16')} = (ω _{re (5 ', 15')} -ω _{re (6 ', 16')} ) / (n _{5 ' , 15'} / n _{6 ' , 16'} ) + ω _{re (6 ', 16')} = (1 / 3-1) (6/5) + 1 = 0.2

While the shaft 4 is rotating, the total volume of the work rooms 100 ', 300' of the set 3 is ω _{T (100 ')} = 6V _100' 2π / 3π = 4V _{100 '} and V _{T (300').} = 6V _{300 '} 2π / 3π = 4V _300' .

While the shaft 4 is rotating, the total volume of the chambers 200 ', 400' is equal to V _{T (200 ')} = 5V _200' 2π / 2.5π = 4V _{200 '} and V _{T (400')} = 5V _{400 '} 2π /2.5π=4V _{400 '} .

From the foregoing it has been clarified that in the case of differential movement of the element, the angular cycle is varied by changing the relative angular velocity of the motion of the propulsion element forming the workroom according to the invention. The angular cycle is 90 degrees in set 1, 360 degrees in set 2, and 540 degrees in set 3. In other words, it is reduced by the compression of the working medium and by the expansion of the working medium according to the invention. Thus, the efficiency of the method according to the invention is improved.

The axial movement of the working medium exerted along the Z-axis of the work chambers 100, 200; 300, 400 is limited to the direction of rotation of the center 0 ₆ , 0 ₁₆ of the elements ₆ , ₁₆ in the set 1. As described above, by selecting the working medium operation in the same direction, the rotation of the center 0 ₆ , 0 ₁₆ indicates the same direction. If one wishes to select the working medium operation of the workrooms 100,200 on one side and the workrooms 300,400 on the other side in the opposite direction, the rotation of the center (0 ₆ , 0 ₁₆ ) should be reversed. do.

In the suction set 1 according to the compression, the compression is carried out while discharging (releasing) the working object to the mechanism 2. By choosing different modes of motion (1, 2), the angular period values of the axial motion of the work room calculated at the switching angle of the output link (4) are likewise different.

The set 1 comprising a group of elements 5, 6, 7; 15, 16, 17 forms an intake section and a precompression section which performs air compression in a continuous-circulating step. The group of elements 8, 9 in the set 2 ensures final compression and discharge of the workpiece. The suction chambers 100, 200 in the differential mechanism 1 are formed by outer groups of paired elements 5, 6, 7 arranged coaxially with the eccentric distances of the internal cavities between each other. Precompression is carried out when air is pumped into the inner group of the coupling elements 15, 16, 17. The synchronization device 11 serves for example to rotate the element-rotors 5, 7; 15, 17 of the set 1 in different directions at an isometric speed in reverse rotation. At the same time, the shaft 4 of the rotor 9 in the set 2 is rotated. The final compression chamber 140 of the planetary mechanism 2 is formed by elements 8, 9, which element 9 rotates by self-synchronization in the crank 10 of the shaft 4. Is hinged to Element 8 is fixed.

The element 9 in the set 2 with respect to the rotational movement of the elements 5 ', 15' in the set 3, hinged to rotate in the stationary body 13, about the central axis Z; The correlation of the rotational movements of the elements 5, 7; 15, 17 in the set 1 is such that the elements (3) in the shaft 4 in the set 3 are driven by the force of the synchronizer 14 with a transmission ratio of three. 5 ', 15', a rigid mechanical connection, hinged shaft 4 and element 9 in the set 2, and rotational inverter with a transmission ratio of -1 ( The force of the synchronous device 11 with an inverter is ensured by the mechanical connection between the shaft 4 and the elements 5, 15 hinged to rotate in the stationary body 13 in the set 1. The elements 8 (stator) of the set 2 and the elements 7 ', 17' (stator) of the set 3 are mechanically rigidly connected to the stationary body 13. The mechanical connection of the elements 5 ', 15' in the set 3 hinged to rotate in the stationary body 13 with the shaft 4 is a synchronous device 14 with a rotary motion reducer with a speed ratio of three. Is made of power.

In parallel with providing synchronization of the internal element rotation of the differential mechanism (1,3), synchronization of the rotation between the differential mechanism (1,3) on one side and the group of planetary mechanisms (2) on the other To be sure. It is also possible to alternate the symmetric orders of the elements of all groups of mechanisms 1, 3 or 2 so that the rotation of the elements of the planets and of the differential mechanisms takes place simultaneously.

The choice of the number of transform groups and the association of planetary and differential kinematic mechanisms is determined by summing the desired angular range of motion and the axial movement period value of the laboratory between the mechanisms.

The engine shown in FIG. 1 operates as follows. Gas (e.g., air) constituting the engine work piece enters the set 1 through the open left end face of the first group of elements 15, 16, 17 in the direction shown by the arrows in FIG. do. The gas is also fed to the open left end face of the elements 15, 16 and 17 of the second group via channels (gaps). The elements 5, 6, 7; 15, 16, 17 (with the elements 8, 9) of the above-mentioned group form a volumetric type rotary propulsion air-compressor 1. Through the channel in the shaft 4, compressed air is directed to leave the set 1 and is delivered to the open left end face of the elements 8, 9 of the combustion set 2, ie to the combustion chamber 140. The compression ratio is 8 (V ₁₀₀ + V ₂₀₀ ) / V ₁₄₀ . After filling the combustion chamber 140 with six air volumes from the compressor 1 and closing it, the device 12 is ignited by injecting fuel into the combustion chamber 140.

In a combustion cycle at a constant pressure (eg a diesel cycle), combustion chamber 140 is formed in which elements 8 and 9 are formed during one period of a birotative twist and fuel firing is carried out by air compression. . In a combustion cycle at a constant volume (eg, an auto cycle), the combustion chamber 140 is formed with two cycles of two turns twists of the elements 8, 9, and fuel ignition is generated by the ignition spark plug. In addition, the ignited fuel-air mixture is led out of the open end face of the elements 8, 9 to expand the opening section to the open bottom face of the elements 15, 16, 17: 5, 6, 7 of the set 3.

When the shaft 4 is rotated, the pairing elements 8 and 9 of the set 2 become independent of the freedom of rotation of the elements 9 in the set 2 defined by the cranks of the shaft 4. Movement of the mating contacts limits the three working chambers 140 of the combustion section 2 along the Z-axis.

As the shaft 4 rotates, the pairing elements 5 ', 6', 7 ', 15', 16 ', 17' of the set 3 are elements 6 ', 16' of the set 3; Between the expansion and exhaust zones 3 (elements in each group (5 ', 6', 15 ', 16') along the Z-axis by movement of the mating contacts in an independent 1 degree of freedom of rotational motion) Move the work medium of the 6th studio and the 5th studio) between the elements 6 ', 7', 16 ', 17'. The complete cycle of axial movement of the workroom between the elements 5 ', 6', 7 ', 15', 16 ', 17' during the rotation of the shaft 4 in the set 1, the shaft 4 Occurs 4 times during 1 revolution. That is, [4 (V _{100 '} + V _200' )] / [4 (V _{300 '} + V _400' )] x [4 (V _{300 '} + V _400' )] / 3V ₁₄₀ = [4 (V _{100 '} + V _{200 '} )] / 3V ₁₄₀ to be.

It is decided to be in agreement. That is, k ₁ = 24 (V ₁₀₀ + V ₂₀₀ ) / [24 (V ₃₀₀ + V ₄₀₀ )] = (V ₁₀₀ + V ₂₀₀ ) / 2 (V ₃₀₀ + V ₄₀₀ ).

The compression ratio k ₂ of the set 2 is, for example, the set 1 relative to the product of the total volume of the three combustion chambers between the elements 8, 9 of the set 2 during the rotation of the shaft 4. Of the product for one product, the first product of the total volume of the six combustion chambers between the elements (15, 16) of) and the second product of the total volume of the five combustion chambers, between the elements (16, 17) of the set (1). It appears to be correlated with the sum. That is, k ₂ = 24 (V ₃₀₀ + V ₄₀₀ ) / 3 V ₁₄₀ = 8 (V ₃₀₀ + V ₄₀₀ ) / V ₁₄₀ .

The overall compression degree k of the engine is k = k ₁ k ₂ = 8 (V ₁₀₀ + V ₂₀₀ ) / V _{140, which} is the product of the compression degrees of the set (1, 2).
