Abstract

The pump has one or two pairs of identical, two-phase coils, each consisting of two parallel, identical tube coils (C1,C1') with a common liquid inlet tube and outlet tube. They are wound in the left- and right-handed sense starting from the input tube. A valve at the start of each coil only allows liquid to move from the input towards the output. The two-phase loop is rigidly attached to a rotor (R1) subjected to a periodic pendulum motion via a crank rod-crank system. Two pumps can be connected in parallel to form a four-phase pump

Description

The present invention relates to a mechanism consisting of a System of pipe circuits transferring rotor inertial forces of a periodic type Pump that has a pressure and a pressure in the liquid they contain Develop a continuous-flow delivery capacity in accordance with the generic term of Claim 1.

One of the objects of the present invention is to make a pump easier To propose design, versatile application and cost-effective production. Another task is to create a pump that few, one Organs exposed to wear require space-saving and are suitable for easy to be expanded to higher delivery rates and pressures.

These and others appearing in the course of the following description Tasks are characterized by the characterizing features of claim 1 solved.

The proposed pump has the advantage of increasing the pressure in pipe circuits develop along the axis inertial forces according to the type of vortex or rotor Every element of the liquid contained an elementary pressure difference amount, the integral of which gives a pressure which, from the inlet to the outlet of the Pipe circuit grows. In this way, it has no mechanical action exposed fluid to extremely modest hydraulic losses.

The proposed pump has the advantage that it does not have a predetermined limit Speed of rotation, such as with piston pumps, any other has a special speed of rotation, as with centrifugal pumps: this, while the only speed limit of the proposed pump is that which is determined by the strength of the materials used for their manufacture.

The proposed pump has the advantage that it has no mechanical organs such as pistons, membrane for protecting them, a variety of impellers in Dependence of the developed pressure, hydraulic devices for Conversion of kinetic energy into pressure energy; the organs mentioned reduce printing performance and increase manufacturing and maintenance costs. The only additional organs of the proposed pump are the unidirectional valves that however, are always open, with the exception of the only transition phase in their Start.

In the proposed pump, the pressure developed is proportional to the product ρn _s ϕ _o r 2 / on ² , in which the variables n ₅ and ϕ _{o are} absolutely new.

Regarding the variables ϕ _o °, it should be noted that it can be conveniently set in the interval ϕ (1 °; 10 °) and that its amount can therefore also be selected in order to obtain the desired values for the other variables in play.

Regarding the variable n _s = number of turns of the active circuit, it should be noted that it replaces the function of the plurality of impellers and the corresponding diffusers used in the centrifugal pumps to increase the pressure developed: the replacement by the number The winding has the advantage of a radical simplification of the construction and reduction of the manufacturing and maintenance costs. moreover, the number n _s can easily be improved with modest changes of ϕ _o , r _o and n.

The kinetic energy of the proposed pump is constant because it consists of one or two pairs of identical rotors formed with the same frequency and swing or pivot with the same phase difference of 90 °. This eliminates the need to use flywheels.

The amount of the highest centrifugal force of the oscillating masses 'm' expressed by f c = mr 0  2nd ϕ 2nd O r 2nd O is relatively small because the coefficient ϕ 2 / o <0.03 reduces the amount of the product described above to less than 3%. This simplifies the balancing of the rotors.

The proposed pump has the advantage that it does not have organs like Has stuffing boxes, diaphragms and pistons which, besides those already above given reasons, the most likely reason for possible leakage from are dangerous liquids.

The proposed pump has the advantage of also pumping to be able to carry out "muddy waters" since they are made of smooth pipes small hydraulic resistance exists, which moreover at every point Pressure increase is generated.

The proposed pump along with the advantage of being extremely high Efficiency, of relatively negligible manufacturing and Maintenance costs and versatility in use, the exclusive Advantage on, with negligible additional costs in a polyfunctional pump to be transformed to at the same time numerous demands of pump types to satisfy.

A.3) DESCRIPTION OF THE FIGURES

a) Der Rotor R₁ besteht aus zwei Blechscheiben angemessener Stärke und kreisrunder Ausbildung, in deren Mitte eine Durchbohrung ausgenommen ist, die Lager Nr. 17 der Drehwelle Nr. 15 des Rotors und in der Figur angegebenen Position des Domes Nr. 13. Die beiden Blechscheiben sind durch einen Streifen zylindrischer Form verbunden, von dem der Querschnitt gezeigt ist, der die Durchdringung der Verbindungsrohre und der Kurbelstange erlaubt;

b) festgelegt wird  = 0°, der Drehwinkel der Kurbel Nr. 5, im Bereich dessen die Drehgeschwindigkeit des Rotors R₁ maximal ist. Nachdem die Punkte O e O₁ und die Gerade durch O senkrecht zu OB₁ bei  = 0° gezogen ist, wird die Überschneidung seines Punktes O_M mit den senkrechten durch O₁ festgelegt. Auf der Geraden OO_M werden die beiden Punkte O₂ e O₃ derart festgelegt, daß O2OM= OM03=OB1 ist. Es werden die Längen OB₁ und O₁O_M derart festgelegt, daß der Winkel am Scheitel O₁ des Dreieckes =O₁O₃O₂ den Wert 2ϕ₀ annimmt, wo ϕ₀ der vorgegebene Winkel des höchsten Winkelausschlages mit Uhrzeiger- und Gegenuhrzeigersinn des Rotors R1 ist. Die Genauigkeit der Berechnung von ϕ₀ nimmt mit der Zunahme von OO_M und der Abnahme von ϕ₀ zu. Die Schaltungen C₁ und C_1' werden am R₁ wie in Figur dargestellt befestigt.

c) Die Position des Einganges E₁ und des Ausganges U₁ der zweiphasigen Schaltung wird in der Nähe der Durchmesserenden des zur Geraden OO_M parallelen Rotors festgelegt, um Interferenzen mit anderen Bestandteilen zu vermeiden und die Verbindung mit den anderen Schaltungen möglichst geradlinig zu halten. Die Position des Einganges E₁, die jedoch immer durch das Paar von einsinnigen Ventilen begleitet ist, kann immer mit der Position des Ausganges U₁ ausgetauscht werden. Auf ähnliche Weise geht man bei den anderen Rotoren vor, die mit derselben Welle Nr. 4 über Kurbeln unter Phasenwinkel gegenüber der Kurbel des in der Beschreibung angegebenen R₁ gekoppelt sind.

Fig. 1 - It shows an example of the modalities to be observed in order to develop a field of vortex or rotor inertial forces in a two-phase circuit. The figure specifies: a) the shape of the rotor R ₁ ; b) the positions: the point O of the axis of shaft No. 4 of the cranks; of point 0 _{1 of} the axis of shaft No. 15 of rotor R ₁ ; the point B _{1 of} the axis of the pin No. 7 of the crank No. 5 coupled to the head of the crank rod No. 9 and the point B _{2 of} the axis of the mandrel No. ₁ fastened to the rotor R ₁ and coupled to the foot of the crank rod No. 9 13; it is assumed that the four axes are parallel and the points O, 0 ₁ , B ₁ , B _{2 are} coplanar; c) the position of the input E ₁ and the output and output U _{1 of} the two-phase circuit.

a) The rotor R ₁ consists of two sheet metal discs of appropriate strength and circular design, in the middle of which a through hole is excluded, the bearing No. 17 of the rotary shaft No. 15 of the rotor and the position of the dome No. 13 indicated in the figure. The two Sheet metal disks are connected by a strip of cylindrical shape, of which the cross section is shown, which allows penetration of the connecting tubes and the crank rod;

b) is determined  = 0 °, the angle of rotation of crank No. 5, in the range of which the speed of rotation of the rotor R _{1 is} maximum. After the points O e O ₁ and the straight line through O are drawn perpendicular to OB ₁ at  = 0 °, the overlap of its point O _M with the perpendicular is determined by O ₁ . The two points O ₂ e O _{3 are} defined on the straight line OO _{M in} such a way that O 2nd O M = O M 0 3rd = OB 1 is. The lengths OB ₁ and O ₁ O _{M are determined in} such a way that the angle at the apex O _{1 of} the triangle = O ₁ O ₃ O ₂ assumes the value 2ϕ ₀ , where ϕ _{0 is} the specified angle of the highest angular deflection clockwise and counterclockwise of the rotor is R1. The accuracy of the calculation of ϕ ₀ increases with the increase in OO _M and the decrease in ϕ ₀ . The circuits C ₁ and C _{1 '} are attached to R ₁ as shown in the figure.

c) The position of the input E ₁ and the output U _{1 of} the two-phase circuit is determined in the vicinity of the diameter ends of the rotor parallel to the straight line OO _{M in} order to avoid interference with other components and to keep the connection with the other circuits as straight as possible. The position of the input E ₁ , which is always accompanied by the pair of unidirectional valves, can always be exchanged with the position of the output U ₁ . A similar procedure is followed for the other rotors, which are coupled to the same shaft No. 4 via cranks at a phase angle with respect to the crank of the R ₁ specified in the description.

Fig. 2 - It shows four two-phase circuits CB ₁ , CB ₁₁ , CB ₂ , CB ₂₂ , which consist of the four pairs of active circuits (C ₁ , C _{1 '} ), (C ₁₁ , C _11' ), (C ₂ , C _{2 '} ), (C ₂₂ , C _22' ) exist. They are obtained from a tube which is curved according to a circle, from which, in a diametrically opposite position, the input E _i and the output U _{i are} derived, where i = 1,11,2,22. Each two-phase circuit, of which only the main axis is shown for reasons of simplicity, has in the area of the outer input E _i an inner cross section E ' _i - the diameter of which is part of the longitudinal axis of E _i - which is the common input of the circuits C _i and C. _{i '} forms. In the same area, two directional valves V _i and V _{i 'are installed} with a sense of opposite consent, which, starting from their input, is left-handed for the circuit C _i and right-handed for the circuit C _i' . The two circuits end in the area of the section U ' _i , the diameter of which belongs to the longitudinal axis of the outer output U _{i of} the three-phase circuit.

Fig. 3 - It represents a two-phase circuit CB _i where i = 1,11,2,22, which consists of a tube which is curved according to a circle, from which, in diametrically opposite positions, the input E _i and the output U _{i of} the two-phase circuit is derived. In Fig. 3) are indicated: the section E ' _i , which is common to both circuits C _i e C _i' , the same direction valves V _i , V _{i '} , the common section of the input E' _i and the output U ' _{i of} the two circuits C _i e C _{i '.}

Fig. 4 - It represents a two-phase circuit obtained from a cylindrical spiral consisting of an odd number of turns. From the center of the winding, which is the number of turns of each active circuit expressed by n s = K + 0.5 , where K is an integer, the input E _{i is derived} with the section E ' _i , which is common to the two circuits C _i and C _i' , where i = 1,11,2,22, which follows a section of n _s windings with opposite directions of rotation, which have inner output cuts U ' _i and U' _{i '} , from whose connection the output U _{i is} derived. In this way, the origins of the input and output axes of the two-phase circuit belong to two different, flat halves of a plane which is separated by the longitudinal axis of the cylindrical spiral. This axis coincides with the axis of rotation of the rotor on which the two-phase circuit is attached. In the area of the E ' _i , the valves V _i and V _{i' are} attached, each of which has a sense of conduction to the corresponding outlet. The dashed lines represent the projection of the spiral on a parallel and averted plane. In the figure, the turns are spaced from each other for clarity; in reality, they are mutual.

Fig. 5 - In it the axes of the two circuits C _i and C _{i '} are shown, where i = 1,11,2,22, bent from the entrance to the exit with left-handed and right-handed sense according to two sections of an Archimedes spiral and such are connected to form a two-phase circuit CB _i . The two circuits are identical since they can be placed one above the other after folding over 180 ° of the support plane. They have a number of turns n s = k + 0.5 where k is an even number such that the input E _i and the output U _i correspond to the two opposite radii of the spiral. The circuits connected by a dashed line for better comprehensibility are to be stacked on two parallel levels in such a way that the points of the pairs (E '_i;E' _{i '} ), (U' _i , U _'i' ) are in contact with one another 16 are to be connected in the manner from which the input E _i of E ' _i and the output U _{i of} the two-phase circuit of U' _i can be derived. In this way, E _i and U _i assume a position that is similar to that described with reference to FIG. At E ' _i and E' _{i '} , unidirectional valves V _i and V _{i' are} introduced.

Fig. 6 - It shows the axes of the two circuits C _i (left-handed) and C _{i '} (right-handed) of a two-phase circuit CB _i , both of which consist of an identical, odd number of identical sections of an Archimedes spiral. Each section has a number of turns n s = k + 0.5, where k is an even number; this is a position on opposite radii of the entrance and exit of each section. In addition, two successive sections alternately have inner and outer entrances and exits. The above features allow the section [1] to be placed one after the other, all the other sections [2], [3], [4], [5], [6] indicated in the figure, with the possibility of the inputs E and the outputs U connect that are adjacent after stacking; and also to derive the input E _i and the output U _{i of} the two-phase circuit from the connection of E ' _i to E' _{i '} and of U' _i to U '_i' . E _i and U _i assume the position which is similar to that described with reference to FIG. 4. The valves V _i e V _{i 'are} installed in the area of E' _i and E '_i' .

Fig. 7 - It shows the assembly diagram of a two-phase pump using the two two-phase circuits CB ₁ and CB _2. In it, the liquid follows the course shown in the figure: connector No. 41, attached to frame No. 1; Input of pump E ₀₁ ; Hose No. 39; movable input E ₁ ; Course up to the exit U ₁ , described in Fig. 2) e 3); Hose No. 39; fixed output U ₀₁ from CB ₁ ; Connector no. 41; Input E ₀₂ from CB ₂ ; Hose No. 39; movable input E ₂ ; Course to U ₂ , described in Fig. 2) e 3), hose No. 39; Output of pump U ₀₂ ; Connector No. 41.

Fig. 8 - It shows the assembly diagram of a four-phase pump, which consists of two parallel, two-phase pumps. Each of these consists of a series of two identical, two-phase circuits, which are however arranged such that the input of the four-phase pump consists of the parallel, four circuits C ₁ , C _{1 '} , C _22, C _22' with a relative phase to  = 0 °, 180 °, 90 °, 270 °. This is essentially the complete compensation of the flow rate at input E ₀ and at output U ₀ . The course of the liquid between the inputs and the outputs (E ₀₁ , U ₀₂ ) and (E ₀₂₂ , U ₀₁₁ ) is very similar to that described for FIG. 7.

Fig. 9 - It shows the sinusoidal profile of the positive components of the inertial forces f ₁ and f _{1 '} , which are exerted on the liquid at the output of the respective circuit C ₁ and C _1' in the interval  (0 °; 360 °). Both forces are developed in the two-phase circuit CB _{1 of} a two-phase pump.

Fig. 10 - It shows the sinusoidal course of the positive components of the inertial forces f ₂ and f _{2 '} , which are exerted on the liquid at the output of the respective circuits C ₂ and C _2' in the interval  (0 °; 360 °). Both forces are developed in the two-phase circuit CB _{2 of} a two-phase pump.

Fig. 11 - It shows the course of the resultants of the positive components of the inertial forces shown in Figs. 9 and 10. The course of the assumption that the two-phase circuits of Figs. 9 and 10 are identical is identical to that of a two-phase pump between the ends E ₀₁ and U ₀₂ in the interval (0 °; 360 °) is developed. The developed inertia has a minimum amount equal to the maximum amount shown in Figures 9 and 10 and a maximum amount √2 times larger.

Fig. 12 - It shows the section of a polyfunctional pump with two parallel axes of rotation, which is placed in the area of the plane that the axes of rotation of the rotors R _i (i = 1,11,2,22) and the axes of the connecting pieces No. 41 and No. 42, which are attached to frame No. 1, and with the assumption that for the angle  = 0 °, in the area of which the speed of the rotor R ₁ assumes a maximum amount, this plane also the entrance and exit axes of the No. 43 connectors attached to the rotor and successively aligned with the axes of the corresponding connectors attached to the No. 1 frame. This has the advantage that the stress on the hoses caused by the bend is zero for  = 0 ° and reaches an identical maximum amount for erreicht = ± 90 °, which represents the smallest possible maximum stress. It should be emphasized that for better understanding of the drawing, all rotors are shown in FIG. 12 with an identical phase and revolve around the shafts No. 15 or No. 16 shown in the figure. The polyfunctional pump shown consists of the entirety of the two two-phase pumps with inputs and outputs (E ' ₀ , U' ₀ ) and (E '' ₀ , U '' ₀ ) and a four-phase pump with input and output (E ₀ , U ₀ ). The pumps shown consist of a total of four two-phase pumps, which are designed with the two-phase circuits shown in Figure 2. The course of the liquid in the four-phase pump is identical to that of Figure 8; while the course of the liquid of the two pumps with inlet and outlet (E '₀;U' ₀ ) e (E ''₀; U '' ₀ ) is identical to that from FIG. It should be noted that: 1) the fixed connectors bound to the support frame are equally distributed on the two opposite sides of the support frame; 2) the axes of the corresponding, movable and fixed connecting pieces and the connecting hose are contained in a plane which is perpendicular to the axis of rotation of the rotor; 3) the two origins of the two movable input and output connectors of each two-phase circuit attached to a rotor are arranged on a plane belonging to the axis of rotation of this rotor; the axis divides the plane into two plane halves, one of which is the origin of the connector of the entrance and the other is the origin of the connector of the exit; 4) in the range of the angle of rotation ϕ = 0 (see FIG. 1) this level also includes the origins of the corresponding fixed connecting pieces bound to the support frame; 5) the two-phase circuits are attached to the corresponding rotor by welding or the like; 6) shafts No. 15 and No. 16 are freed from the inner part to the rotors in order to make more space inside the rotor; in special cases it is preferable to leave them whole; 7) the use of two shafts to rotate the rotors instead of a single one has the advantage that the inlet and the outlet of each pump are arranged on two opposite sides of the support frame. The axis BB 'shown in the figure belongs to the vertical plane on which, parallel to the axis of shafts No. 15 and No. 16, the axis of the shaft of cranks No. 4 is arranged, which determines the pivoting movement of the rotors as described in FIG. 13.

Fig. 13 - It shows the section AA 'shown in Figure 12, with the assumption that the angle of rotation of crank No. 5  = 0 °. The position of the two two-phase circuits CB ' ₁ and CB' _{2 is} taken from the section. The liquid, see also FIG. 12, enters E _'01 , passes through connector No. 41 and hose No. 39, feeds via connector No. 43 to the two branches of the two-phase circuit CB' ₁ , from which it is connected the rear hose 39, which cannot be seen in FIG. 13, enters the connection piece 41 fastened to the frame, from which it flows into the rear hose 39 fastened to the rotor R ₂ in the highest bending position until it flows feeds the two-phase circuit CB ' ₂ , from which it emerges via a connector No. 43 into a front hose No. 39, which is connected to connector No. 41 and at whose end there is the outlet U' _{01 of} the pump. The figure also shows the crank / crank rod system which is used for the back and forth movement or pendulum movement of the two rotors. It can be seen: the section of the shaft of the cranks no. 4; the bolts No. 7 and No. 12 connected to the head of the crank rod No. 9 and No. 10, respectively, and the mandrels No. 13 and No. 14 coupled to the foot of the crank rod No. 9 and 10, and the openings recessed in the rotors , for the passage of the hoses and the crank rods. It should be noted that the figure 13) is enlarged compared to figure 12) in order to emphasize their details.

Fig. 14 - shows the section of a polyfunctional pump according to the plane of the axis No. 15 of the rotors R ₁ and R ₂ and the connecting pieces No. 41, No. 42 attached to the support frame No. 1. It is assumed that for  = 0 ° this plane also contains the input and output axes of the connecting pieces No. 43 fastened by the rotor R ₁ , which are aligned with the axes of the corresponding connecting pieces fastened to the frame No. 1. For better understanding, the two rotors are shown with an identical angle of rotation. The polyfunctional pump differs from that of FIG. 12 in that the rotors used all revolve around shaft No. 15, the axes of which are aligned with a single straight line. This means that the inlet and outlet of each pump are located on a single side of the support frame. The polyfunctional pump shown consists of a two-phase pump with input E ' ₀ and output U' ₀ and a four-phase pump with input E ₀ and output U ₀ . The input E ₀ is connected to the parallel of the two two-phase circuits CB ₁ and CB ₂₂ , the circuits of which have a relative input phase of 0 °, 180 °, 90 °, 270 °. The flow of liquid is similar to that described with reference to FIGS. 7), 8) and 12). The diagram from FIG. 14) can be advantageous from an economic point of view because it is structurally simpler and consequently less expensive. In the presence of a single axis of rotation of the rotors, it is also favorable to use the system of the 'guided bearing' described below for their reciprocation.

Fig. 15- It shows the section AA ', which is given in Fig. 14 with the assumption that  = 270 ° is the angle of crank number 5, on which the movement of R ₁ depends, that in the considered Moment that maximum rotation ϕ = ϕ _{0 has been} completed. The following can be seen: - hose no. 39, which connects the output of circuit CB ₁ to connector no. 42; - the hose connecting the input of circuit CB ₁ to connector no. 42; - the connecting rod No. 9, which is fixed to the crank pin 7 and to the mounted on the mandrel _R1;. - The shaft of crank No. 4 and the pivot bearing 17 of R ₁ . In FIG. 15) the axis of the shaft of the two cranks for the movement of the two rotors R ₁ and R _{2 is arranged} in the section BB ′ indicated in FIG. 14.

Fig. 16 - It shows the T-shaped connector No. 43, which can be used in the two-phase circuits when the points C _i and C _{i 'to be connected have} one axis in common. The vertical axis of the T represents the input axis E _i and the output axis U _{i of} the two-phase circuit and is normally bent rectangularly as shown in the figure in order to be connected to the connecting piece fastened to the support frame (see FIG. 12) and 14)) facilitate. The horizontal bar of the T is used to connect the circuits C _i e C _{i '} .

Fig. 17 - It shows the connector used in the two-phase circuits when the points C _i and C _{i '} to be connected belong to two different axes of the same circuits. This is that the horizontal bar of the T is divided into two spaced bars, as are the axes of the circuits C _i and C _{i '} . The vertical bar of the T has a shape that is identical to that of the connectors from Fig. 16).

Fig. 18 - It shows the side view of the polyfunctional pump from Fig. 12). The following components are shown: the support frame No. 1; rotors R ₁ and R ₂ ; the shaft of crank number 4; Part of crankshaft No. 9 for the movement of R ₁ ; No. 7 pin and No. 13 mandrel to which the crank rod is connected; Part of the crank rod No. 10 for the movement of R ₂ and the mandrel No. 14 with which it can be connected; shaft 15 and 16 attached to frame No. 1, around which rotors R ₁ and R ₂ rotate, respectively; the input E ' ₀ and the output U' _{0 of} a two-phase pump belonging to the polyfunctional pump.

Fig. 19 - It represents a mechanism that allows for the rotational movement of one a support frame attached bearings rotating shaft of the cranks in a Convert pivotal movement of a rotor to that on the support frame attached shaft No. 15 is pivotable. The mechanism consists of: a) a No. 4 shaft of the cranks with one for Drebwelle No. 15 of the rotor 2 parallel axis; b) from the pair of cranks No. 5, who circulate outside of guided tours No. 45 and also have the task of compensate for eccentric masses of bearing No. 9 and pin No. 7; c) the Bolt No. 7 of the cranks; d) bearing no. 9 applied to bolt no. 7; e) the Pair of guides No. 45 with parallel inner surfaces that belong to two levels, which are equally spaced from the axis of rotation of shaft No. 15. The guides are rigidly attached to the rotor in its inner part and between them is with close tolerance the outer ring of bearing No. 9 is arranged. The whole is coordinated in such a way that when shaft 4 rotates, the bearing rotates alternately on one of the guides, causing the rotor to reciprocate.

B.1) THE SIMPLE, ACTIVE CIRCUITS

They have the task of increasing the pressure difference in the liquid contained generate, which is necessary for the operation of the pump. This justifies them given name of an active circuit. They consist of a tube circular or rectangular cross-section; their axis is according to one Curved curvature that is a section of a circle or a cylindrical Spiral or an Archimedes spiral can be.

The active circuits considered in the following description are the four left-hand circuits C _i , where i = 1,11,2,22 and the four right-hand circuits C _{i '} where i' = 1,11 ', 2'22' . The circuits C _i and C _{i '} have a liquid inlet and outlet, which are each indicated by E' _i , and U ' _i and E' _{i '} U' _{i '} .

The circuits C _i and C _{i '} are each to be considered left-handed and right-handed, since the sense of rotation is left-handed and right-handed from their input to their exit. The sense of running is relative to the utility c the normals at their common support level. In the area of the input of each circuit C _i and C _{i '} are arranged the unidirectional valves with a sense of consent from the input to the output, which are each indicated by V _i and V _i' . They consist, for example, of a closing plate guided by a central axis and have the task of allowing the liquid to enter and preventing it from escaping.

The eight active circuits are distributed on different rotors according to the following scheme, which are called jurisdiction rotors: Circuits Jurisdiction rotor C ₁ , C _{1 '} R ₁ with relative phase  = 0 ° C ₂ , C _{2 '} R ₂ with relative phase  = 90 ° C ₁₁ , C _{11 '} R ₁₁ with relative phase  = 180 °, or R ₁ in the absence of R ₁₁ C ₂₂ , C _{22 '} R ₂₂ with relative phase  = 270 °, or R ₂ in the absence of R ₂₂

The active circuits develop the usable pressure through inertial forces according to the rotor type, which are generated by angular accelerations. For this purpose, they are rigidly attached to rotors, which are imposed on a periodic reciprocating or pendulum movement about their axis of rotation, which coincides with the axis z of a Cartesian reference system (0, xyz) with axes that each pass through the suppliers a , b , c are aligned.

Each circuit is attached: 1) in such a way that the surface S _{0 of} its projection on the plane (0, x, y) is determined by the relationship S O = 1 / 2∫ s c × r · t 1 ds which represents the integral along the longitudinal axis s and the center of gravity of the circuit, whose element ds is a tangent with Versor t ₁ and vector r possesses, reached a maximum; 2) such that the path along the axis s of the circuit in the sense permitted by the valve arranged at the input of the circuit to the supplier c is counterclockwise for circuit C _i and clockwise for circuit C _{i '} .

The active circuits C ₁ , C ₁₁ , C _{1 '} , C _11' are on the rotor R ₁ , while C ₂ , C _{2 '} , C ₂₂ , C _22' on the rotor R ₂ . are attached. For pumps with limited claims, the active circuits C ₁₁ , C _{11 '} , C ₂₂ , C _22' may be absent; while in special cases the active circuits on four rotors R ₁ , R ₂ , R ₁₁ , R ₂₂ can be attached in the following way: C ₁ and C _{1 '} on R ₁ ; C ₂ and C _{2 '} on R ₂ ; C ₁₁ and C _{11 '} on R ₁₁ ; C ₂₂ and C _{22 '} on R ₂₂ . In this case, the angle  of the respective cranks one after the other has the relative amount:  = 0 °, 90 °, 180 °, 270 °.

The rotors (see Fig. 12) rotate about the parallel axes of shaft # 15 and 16 attached to the support frame. Waves No. 15 and No. 16 do not have a central section to accommodate the tubing. In the absence of the shaft No. 16, all rotors are mounted on shaft No. 15 (see Figure 14).

The presence of shaft no. 16 is particularly useful for high pumps Delivery capacity or in the case of polyfunctional pumps with two-phase circuits, that take up a lot of space, including the required ratio between length and To be able to determine the width of the support frame. Using shaft number 16 the series of two two-phase circuits can also be carried out avoiding the U-shaped connectors and the respective losses become.

The movement of the rotors mounted on shaft 15 and 16 is controlled by a single shaft carried out with four cranks with identical radius and relative phase 0 °, 90 °, 180 °, 270 ° is equipped with four identical Crank rods are connected, the foot of which is attached to a mandrel attached to the rotor connected is; the axis of the cathedral has an identical radius in all Rotors; it is also the distance of the axis of rotation of each rotor from the Axis of rotation of the shaft of the cranks are identical; therefore the movement differs of the rotors only because of the phase.

The rotors are subject to a periodic pendulum movement about their axis of rotation due to a coupling rod / crank system as above with reference to FIG. 1 described; or due to an equivalent system, as below suggested.

wo ϕ₀ den absoluten Betrag der höchsten, Links- oder Rechtswinkelverschiebung des Rotors darstellt und  der Drehwinkel der Kurbel ist.The calculation of the movement of the system shown in FIG. 1 with four bars OB ₁ , B ₁ B ₂ , B ₂ O ₁ , O ₁ O is complicated and its results cannot be interpreted immediately. Therefore, assuming that  ˙ is constant, the pendulum motion of the rotor R ₁ is assumed to be described by the following equations:

where ϕ _{0 represents} the absolute amount of the highest, left or right angle shift of the rotor and  is the angle of rotation of the crank.

In Fig. 1 the points 0, O ₂ , O ₃ belong to a straight line which is perpendicular to the straight line O ₁ O _M , where O _{M is} the middle point of the segment O ₂ O ₃ . The points O ₂ and O ₃ are the outermost points of the path of the axis of the crank rod foot, in the area where the maximum accelerations of the rotor take place.

dem eine Druckdifferenz zwischen der Querschnitten E'_i und U'_i

entspricht.From this it follows that the liquid mass of the circuit C _i is subject to an inertial force which increases from E ' _i to U' _{i '} , the instantaneous maximum amount of which is expressed in cross section U _i by:

which is a pressure difference between the cross sections E ' _i and U' _i

corresponds.

For ϕ ° <10 °, an amount in most cases of applications is not

is exceeded, the error contained in the above equations is for a Calculation basis of the machine largely permissible. The above, Simplified equations are therefore provided for the purposes of the present Invention is considered to be valid and is in constant use in all subsequent parts used.

B.2) THE ACTIVE, TWO-PHASE CIRCUIT

The use of the two-phase circuit has the task: 1) to develop in the interval 0 (0 °, 360 °) a useful pressure difference of constant sign and continuous character in the liquid lying between the input and output cross sections U _i and E _i , the phases opposite sign of the acceleration of the rotor to which the two-phase circuit is attached; from this comes the name of the 'two-phase' circuit that is given to the circuit; 2) To develop a constant liquid flow rate of constant sign in both phases.

• indem die beiden Eingänge E'_i und E'_i' und die beiden Ausgänge U'_i und U'_i' eines jeden Paars von Schaltungen, miteinander verbunden werden, wo i=1,11,2,22;
• indem der Eingang E im Bereich der Verbindung von E'_i und E'_i' und der Ausgang U_i im Bereich der Verbindung von U'_i mit U'_i' abgeleitet werden;
• indem gleich nach den Eingängen E'_i und E'_i' die Richtventile V_i und V_i' mit Zustimmungssinn vom Eingang zum Ausgang der Flüssigkeit eingefügt werden.

From four identical pairs of circuits (C ₁ ; C _{1 '} ), (C ₁₁ ; C _11' ), (C ₂ ; C _{2 '} , C ₂₂ ; C _22' ), the four two-phase circuits (see FIG. 2 ) in the following way:

• by connecting the two inputs E ' _i and E' _{i '} and the two outputs U' _i and U '_i' of each pair of circuits, where i = 1,11,2,22;
• in that the input E in the area of the connection of E ' _i and E' _{i '} and the output U _i in the area of the connection of U' _i with U '_{i' are} derived;
• by inserting the directional valves V _i and V _{i '} with the sense of consent from the inlet to the outlet of the liquid immediately after the inputs E' _i and E '_i' .

Here, the two-phase circuit consists of a right-hand circuit C _{i '} , which is parallel to the left-hand circuit C _{i of} identical surface S ₀ , both of which are equipped with a directional valve that only allows the liquid to travel from the entrance to the exit. In this regard, the forces and velocities from the entrance to the exit are given as positive.

erzeugt, die: 1) zwischen den Querschnitten U₁ und E₁ den Druckunterschied f₁/S_c festlegt; 2) in der Flüssigkeit von C₁ eine positive Geschwindigkeit beträgt; 3) mit der gleichen und entgegengesetzten Kraft f_1' eine Resultierende bildet, die dazu neigt, die Geschwindigkeit der Flüssigkeit der Schaltung C₁' zu annullieren, die in derselben von f₁' in  (180°; 360°) entwickelt wird.In the interval  (0 °; 180 °) (see Fig. 9), the negative acceleration of the rotor R _{1 of} the liquid of the circuit C _{1 is} transmitted, in which it is an inertial force

which: 1) defines the pressure difference f ₁ / S _c between the cross sections U ₁ and E ₁ ; 2) there is a positive velocity in the liquid of C ₁ ; 3) with the same and opposite force f _{1 'forms} a resultant who tends to cancel the speed of the fluid of the circuit C ₁ ' developed therein by f ₁ 'in  (180 °; 360 °).

In the interval  (180 °; 360 °), the force f _{1 '} > 0: 1) between the cross sections U ₁ e E ₁ Idie the pressure difference p _G1' similar to p _G1 ; 2) develops a positive velocity in the liquid of C _{1 '} ; 3) forms a resultant with the negative force f ₁ , which tends to cancel the speed of the fluid of the circuit C ₁ .

Extreme ausgeschlossen, festlegt, wo |sen| der vertikale Wert von sen ist; sein Verlauf ist immer identisch jenem aus Figur 9; 2) in der Flüssigkeit der Schaltung C₁ eine Förderleistung mit einem Mindestbetrag von  = 0° und einen Höchstbetrag von  = 180° festlegt; 3) in der Flüssigkeit der Schaltung C_1' eine Förderleistung mit einem Mindestbetrag für  = 180° und mit einem Höchstbetrag  = 360° festlegt; 4) zwischen den Querschnitten U₁ und E₁ eine Förderleistung festlegt, die gleich der Summe der Förderleistungen der Schaltungen C₁ und C_1' ist.It can be said that if other forces are excluded, the two-phase circuit CB ₁ in the interval  (0 °; 360 °): 1) between the cross sections U ₁ and E _{1 has} a positive pressure difference

Extreme excluded, determines where | sen | is the vertical value of sen; its course is always identical to that of Figure 9; 2) in the fluid of the circuit C ₁ defines a delivery rate with a minimum amount of  = 0 ° and a maximum amount of  = 180 °; 3) in the fluid of the circuit C _{1 '} defines a delivery rate with a minimum amount for  = 180 ° and with a maximum amount  = 360 °; 4) between the cross sections U ₁ and E ₁ defines a delivery rate that is equal to the sum of the delivery rates of the circuits C ₁ and C _{1 '} .

The other two-phase circuits CB ₁₁ , CB ₂ and CB ₂₂ have a similar behavior in the respective intervals of responsibility.

B.3) DESIGNING THE TWO-PHASE CIRCUIT

a) Die zweiphasige Schaltung CB_i, deren Schaltungen C_i und C_i' durch ein gemäß einem Kreis gekrümmtes Rohr (siehe Fig. 1,3) erhalten werden, von dem mittels der Verbindungsstücke Nr. 43 der Eingang E_i und der Ausgang U_i in diametral entgegengesetzten Stellungen abgeleitet sind. Im Bereich des Einganges sind an den Schaltungen C_i und C_i' die Ventile V_i und V_i' angebracht. Die Schaltung weist die folgenden Vorteile auf: 1) sie besitzt an jeder Stelle ihrer Achse den Versor der Tangente zusammenfallend mit dem Versor der in der Flüssigkeit entwickelten Trägheitskraft, die an jeder Stelle zum Abstand von der Drehachse proportional ist; dies beschränkt die hydraulischen Verluste und erlaubt, daß die gesamte in der Schaltung enthaltende Flüssigkeitsmasse den höchstmöglichen Beitrag für den Betrieb der Pumpe bietet; 2) sie hat einen herabgesetzten, radialen und axialen Platzbedarf; ist der Querschnitt rechteckig, so wird der Platzbedarf durch jenen eines zylinderförmigen Ringes dargestellt, dessen Querschnitt in der Höhe und der Breite gemäß den Erfordernissen sich ändern kann, wobei dessen Fläche konstant gehalten wird; 3) die Schaltung ist einfacher als jede andere, wodurch sie auch verhältnismäßig niedrige Herstellungskosten hat. Die Schaltung ist insbesondere geeignet, für hydroelektrische Anlagen und, im allgemeineren, für Pumpen mit Förderleistungen jeglicher Größe und Drücken, die verhältnismäßig nicht hoch sind.

b) Zweiphasige Schaltung mit Schaltungen C_i und C_i', die aus einem Rohr ausgeführt sind, dessen Achse gemäß einer zylinderförmigen Spirale gekrümmt ist (siehe Figur 4 und Beschreibung). Der Eingang E_i ist im Bereich der Mitte der Wicklung abgeleitet und im Bereich desselben sind zwei in Richtung des Ausganges ausgerichtete Richtungsventile angeordnet; der Ausgang U_i ist im Bereich der Verbindungsstelle zu den beiden äußersten Stellen abgeleitet. Auf diese Weise erhält man vom Eingang E'_i bis zum Ausgang U'_i' eine rechtsgängige Schaltung C_i' und vom E'_i bis U'_i eine linksgängige Schaltung C_i. Die Zeichnung hebt den Vorteil hervor, für jede anteilige Schaltung eine Anzahl von Windungen ns=0,5+K zu verwenden, wo K eine ganzzahlige Ziffer ist, um den Eingang E_i und Ausgang U_i der CB_i zu haben, die sich in einer Position befinden, die ähnlich jener ist, wie für Figur 4 beschrieben. Die zylinderförmige Spiralaufwicklung besitzt einen hohen Platzbedarf gemäß der Achse z; sie hat jedoch den Vorteil, einen kleinen, radialen Platzbedarf aufzuweisen. Es ist zu bemerken, daß die Windungen des Wickels eng aneinander gelegt werden können.

c) Zweiphasige Schaltung mit aktiven Schaltungen, die aus einem Rohr bestehen, das längs einer ungeraden Zahl von übereinander gelegten, zylinderförmigen Spiralabschnitten gekrümmt ist. Die eng aneinander liegenden Windungen von zwei unmittelbar übereinander liegenden Abschnitten sind, unter Bezugnahme auf einen zu ihrer Achse parallelen Versor, mit identischem Drehsinn aufgewickelt. Auf diese Weise summieren sich die auf die in jedem Abschnitt enthaltene Flüssigkeit angewandten Trägheitskräfte mit identischem Vorzeichen. Die Abschnitte sind derart angeordnet, daß der Endquerschnitt eines jeden Zwischenabschnittes dem Anfangsquerschnitt des unmittelbar oberen Abschnittes angehört, der mit abgewandten Vorschubsinn, jedoch mit identischem Drehsinn aufzuwickeln ist. Die Anzahl der Abschnitte ist ungerade und jeder besitzt eine Anzahl von Windungen ns=K+0,5, wo K eine ganzzahlige Ziffer ist. Die beiden Schaltungen C_i und C_i' sind identisch. Eine derselben ist um 180° um die zur Achse der Windung senkrechten Achse gedreht und längs derselben, gemeinsamen Achse an der anderen Schaltung derart angereiht, daß deren beiden Endquerschnitte anliegend sind, von denen der Eingang (oder der Ausgang) der zweiphasigen Schaltung abgeleitet ist. Der Ausgang (oder der Eingang) ist vom Verbindungsrohr der beiden Querschnitte abgeleitet, die nach Umschlag nach oben sich in äußerten Stellungen, wie für Figur 4 beschrieben, befinden. Die Ventile sind mit Zustimmungssinn in Richtung des Ausganges gleich nach dem Eingang eingebaut.Die beschriebene zweiphasige Schaltung besitzt den Vorteil, eine große Anzahl von Windungen erhalten zu können, wobei der gesamte verfügbare Raum ausgenützt wird. Sie ist vor allem für Pumpen mit sehr hohen Druck und kleiner Förderleistung von Vorteil.

d) Zweiphasige Schaltung mit Schaltungen C_i und C_i', die aus zwei identischen Rohrabschnitten bestehen, deren Achse gemäß einer Spirale von Archimedes gekrümmt ist. Sie besitzt die Aufgabe, eine zweiphasige Schaltung auszuführen, die für einen weiten Bereich von Förderleistungen und von Drücken, von kleinen bis hohen, mit einem sehr begrenzten, axialen Raumbedarf geeignet ist; sie ist überdies zur Herstellung von Mehrfachpumpen, so wie nachstehend beschrieben, angezeigt. Sie ist wie folgt (siehe Fig. 5 und Beschreibung) aufgebaut:

• zwei Rohre werden längs zwei identischen Abschnitten einer Archimedesspirale derart gekrümmt, daß die Außenfläche einer Windung an der Innenfläche der darauffolgenden anliegt; die Anzahl der Windungen eines jeden Rohrabschnittes muß ns=0,5+K sein, wobei K= eine ganze Zahl;
• die Auflageebene einer der beiden Abschnitte wird derart geklappt, daß ausgehend vom Eingang E_i, eine linksgängige Schaltung C_i und eine rechtsgängige Schaltung C_i' erhalten werden;
• die Schaltungen C_i und C_i' werden derart übereinander gelegt, daß die Querschnitte der beiden Paare (E'_i, E'_i') und (U'_i, U'_i') angrenzend sind; an den Eingängen E'_i e E'_i' werden die einsinnigen Ventile V_i und V_i' eingebracht;
• von den Eingängen E'_i e E'_i' wird der Eingang E_i und von den Ausgängen U'_i e U'_i' der Ausgang U_i mit den Verbindungsstücken Nr. 44, siehe Figur 17) abgeleitet; sie sind angeordnet wie für Figur 4) beschrieben.

e) Zweiphasige Schaltung mit anteiligen Schaltungen C_i und C_i', die aus einer ungeraden Zahl n_T von identischen Rohrabschnitten bestehen, deren Achse gemäß dem Verlauf einer Archimedesspirale mit einer Anzahl von Windungen ns=K+0,5 gekrümmt ist, wo K eine ganze Zahl ist. Die anteiligen aktiven Schaltungen besitzen eine große Fläche S₀ und die Pumpe ist daher geeignet, Drücke mit Beträgen zu entwickeln, die zwischen einem mittleren Wert und einem sehr hohen Wert liegen, mit kleinen bis mittleren Förderleistungen.

The two-phase circuits can be implemented in various ways, among which those which are explained below under points a), b), c), d), e).

a) The two-phase circuit CB _i , the circuits C _i and C _{i 'are} obtained by a tube curved according to a circle (see Fig. 1.3), from which by means of connectors No. 43 the input E _i and the output U _i are derived in diametrically opposite positions. In the area of the input, the valves V _i and V _{i 'are} attached to the circuits C _i and C _i' . The circuit has the following advantages: 1) it has at each point on its axis the tangent line coincident with the line of the inertial force developed in the liquid, which is proportional to the distance from the axis of rotation at every point; this limits the hydraulic losses and allows the total mass of liquid contained in the circuit to make the greatest possible contribution to the operation of the pump; 2) it has reduced radial and axial space requirements; if the cross-section is rectangular, the space requirement is represented by that of a cylindrical ring, the cross-section of which can vary in height and width according to requirements, the area of which is kept constant; 3) The circuit is simpler than any other, which means that it also has relatively low manufacturing costs. The circuit is particularly suitable for hydroelectric systems and, more generally, for pumps with delivery capacities of any size and pressures that are not relatively high.

b) Two-phase circuit with circuits C _i and C _{i '} , which are made of a tube whose axis is curved according to a cylindrical spiral (see Figure 4 and description). The input E _i is derived in the area of the center of the winding and in the area of the same are arranged two directional valves oriented in the direction of the output; the output U _i is derived in the area of the connection point to the two outermost points. In this way one obtains from the input E _'i to the output U' _{i 'is} a right-handed circuit C _i' and from e _'i to U' _i a left-handed circuit C _i. The drawing highlights the advantage of a number of turns for each proportional circuit n s = 0.5 + K to be used where K is an integer number to have input E _i and output U _i of CB _i which are in a position similar to that described for Figure 4. The cylindrical spiral winder takes up a lot of space along the axis z; however, it has the advantage of having a small, radial space requirement. It should be noted that the turns of the winding can be placed close together.

c) Two-phase circuit with active circuits, which consist of a tube which is curved along an odd number of cylindrical spiral sections placed one above the other. The closely adjacent turns of two sections lying directly one above the other are wound with an identical direction of rotation with reference to a versor parallel to their axis. In this way, the inertial forces applied to the liquid contained in each section add up with an identical sign. The sections are arranged in such a way that the end cross section of each intermediate section belongs to the initial cross section of the immediately upper section, which is to be wound up with the feed direction turned away, but with the same direction of rotation. The number of sections is odd and each has a number of turns n s = K + 0.5 where K is an integer number. The two circuits C _i and C _{i '} are identical. One of them is rotated by 180 ° about the axis perpendicular to the axis of the winding and is lined up along the same common axis on the other circuit in such a way that its two end cross sections are contiguous, from which the input (or the output) of the two-phase circuit is derived. The outlet (or the inlet) is derived from the connecting pipe of the two cross-sections which, after being turned upward, are in outermost positions, as described for FIG. 4. The valves are installed with a sense of approval in the direction of the output immediately after the input. The described two-phase circuit has the advantage of being able to obtain a large number of turns, making use of the entire available space. It is particularly advantageous for pumps with very high pressure and low delivery rates.

d) Two-phase circuit with circuits C _i and C _{i '} , which consist of two identical pipe sections, the axis of which is curved in accordance with an Archimedes spiral. It has the task of performing a two-phase circuit which is suitable for a wide range of delivery rates and pressures, from small to high, with a very limited axial space requirement; it is also indicated for the manufacture of multiple pumps, as described below. It is structured as follows (see Fig. 5 and description):

• two tubes are curved along two identical sections of an Archimedes spiral such that the outer surface of one turn lies against the inner surface of the next one; the number of turns of each pipe section must n s = 0.5 + K where K = an integer;
• The support level of one of the two sections is folded in such a way that, starting from the input E _i , a left-hand circuit C _i and a right-hand circuit C _{i '} are obtained;
• the circuits C _i and C _{i '} are superimposed in such a way that the cross sections of the two pairs (E' _i , E '_i' ) and (U ' _i , U' _{i '} ) are adjacent; the unidirectional valves V _i and V _i 'are introduced at the inputs E' _i e E '_i';
• from the inputs E _'i e E' _{i 'is} the input E _i, and the outputs U' the output U, see Figure 17) derived e _i U _{'i' i} with the connecting pieces Nos. 44; they are arranged as described for Figure 4).

e) Two-phase circuit with proportional circuits C _i and C _{i '} , which consist of an odd number n _T of identical pipe sections, the axis of which follows a course of an Archimedes spiral with a number of turns n s = K + 0.5 is curved where K is an integer. The proportionate active circuits have a large area S ₀ and the pump is therefore suitable for developing pressures with amounts that lie between a medium value and a very high value, with small to medium delivery capacities.

The two-phase circuit has the following features (see also FIG. 6 and description):

1) the axes of the sections of the circuits C _i and C _{i '} are wound from the input E' _i to the output U ' _i with an alternating increasing and decreasing radius as the winding angle increases; the meaning is left-handed for the sections of C _i and right-handed for the sections of C _{i 'with} reference to the versor c the normal to the common support level;

C.1) THE TWO-PHASE PUMP

It consists of two two-phase circuits CB ₁ and CB ₂ , which are connected in series and are each attached to the rotors R ₁ and R ₂ with the described modalities, which accelerate periodically with an identical frequency and with a relative phase  = 0 °, 90 ° exposed. The inertial forces f ₁ and f _{1 '} , which are generated by the two-phase circuit CB ₁ , which is arranged at the input of the pump, act with the two relative phases 0 ° and 180 ° of the angle ; the name given to the pump by 'two-phase' is derived from this.

The series of two two-phase circuits allows one pump with one Minimum of generated pressure that is equal to the highest pressure that any of the two two-phase, proportional circuits is generated in such a way that to the Pump a useful back pressure can be applied that meets the requirements corresponds to a flow rate without interruption and valves in the same direction get that are constantly open. The series also allows the automatic Setting the delivery rate of the internal circuits so that a periodic Course arises.

The series of the two circuits is shown in Fig. 7 and explained in the corresponding description. It is useful to also check Figs. 12 and 14, which show the arrangement proposed for a two-phase pump with input E ' ₀ and output U' ₀ .

f1=F0sin positiv in  (0°;180°) und negativ in  (180°;360°); und

f1'=-F0sin positiv in  (180°;360°) und negativ in  (0°;180°); in ihnen ist

F0=2ρSoScϕo  2 , die den Höchstwert von f₁ und f_1' im Bereich des Ausganges U₁ (siehe Fig.7) darstellt.

In the interval  (0 °; 360 °) the circuits C ₁ and C _{1 '} of CB ₁ each generate the following inertial forces in the liquid:

f 1 = F 0 sin positive in  (0 °; 180 °) and negative in  (180 °; 360 °); and

f 1' = -F 0 sin positive in  (180 °; 360 °) and negative in  (0 °; 180 °); is in them

F 0 = 2ρS O S c ϕ O  2nd , which represents the maximum value of f ₁ and f _{1 '} in the area of the output U ₁ (see FIG. 7).

Furthermore, the relationship f ₁ + f _{1 '} = 0 applies to every angle  and therefore the absolute values | f ₁ | = | f _1' | are sufficient.

f2=F0sin(+90°) positiv in  (90°;270°) und negativ in  (-90°;+90°); überdies

f2'=-F0sin(+90°) negativ in  (90°;270°) und positiv in  (-90°;+90°);

Für jeden  gelten die Beziehungen f2+f2=0 und |f2|=|f2'|.

In  (0 °; 360 °) the circuits C ₂ and C _{2 '} of CB ₂ generate the inertial forces in the liquid:

f 2nd = F 0 sin ( + 90 °) positive in  (90 °; 270 °) and negative in  (-90 °; + 90 °); moreover

f 2 ' = -F 0 sin ( + 90 °) negative in  (90 °; 270 °) and positive in  (-90 °; + 90 °);

The relationships apply to every  f 2nd + f 2nd = 0 and | f 2nd | = | f 2 ' | .

At every angle  of the interval  (0 °; 360 °), each two-phase circuit in the liquid contains a positive inertial force, the sum of which at the outermost U _{2 of} the series of the two two-phase circuits is equal to the resultant (see Fig. 11): R G = | f 1 | + | f 2nd | = F 0 (| sin | + | cos |).

The resulting R _G corresponds to the instantaneous value of the pressure difference p _G that is generated between the input E ₀₁ and the output U _{02 of} the pump, expressed by:

den Mindestwert

und den Mittelwert

It has the highest value

the minimum value

and the mean

Forces occur during operation of the pump, which change the course of the diagrams above. More precisely in the interval  ( _o ; 180 ° - _o ), indicated with the PHASE I of the operation of the circuit C ₁ , to the mass of the series contained in the series consisting of circuit C ₁ and the circuit CB ₂ and by a positive Powerful liquid that applied positive resultants:

a) RI(1)=2f1+|f2|-pHSc , gültig in (_o;0°) und in (180°;180°-_o), wo _o ein negativer Winkel ist; überdies

b) RI(2)=f1+|f2|-pHSc , gültig in (0°;180°).

R I. = R I (1) + R I (2) , being in

a) R I (1) = 2 f1 + | f 2nd | -p H S c , valid in  ( _o ; 0 °) and in  (180 °; 180 ° - _o ), where  _{o is} a negative angle; moreover

b) R I (2) = f 1 + | f 2nd | -p H S c , valid in  (0 °; 180 °).

In the above relationships, | f ₂ | the absolute value of f ₂ and p H = p s + p cs + p e , where p _{s is} the useful back pressure, p _cs is the pressure loss in the series of the two active circuits C ₁ and C ₂ , and p _e is the pressure loss in the circuits outside the active circuits.

The above resultant brings the speed of the fluid of the circuit C ₁ from a zero value for  = + 0 O to a maximum value for  = 180 ° - _o .

In the subsequent interval  (180 ° - _o , 360 ° +  _o ), indicated as PHASE II of the operation of C ₁ , the above mass is accelerated by a negative resultant R _II , expressed by R II = 2f 1 + | f 2nd | -p H S c , which brings the maximum velocity of the liquid from C ₁ back to a zero value for  = 360 ° +  _o .

Identical considerations can be repeated for the liquid mass of the series of the circuit C _{1 '} and the circuit of CB ₂ , which is accelerated by a positive inertial force.

In PHASE I of the operation of C _{1 '} with respect to the interval  (180 ° +  _o ; 360 ° - _o ), the liquid velocity of C _{1' is} of one of the above similar positive resultants from a zero value for  = 180 ° +  _{o brought} to a maximum value for  = 360 ° - _o ), which is the same as that with respect to the circuit C ₁ ; while in PHASE II of the operation of C _{1 '} a negative resultant, similar to that described above in the interval  (- _o ; 180 ° +  _o ), brings the liquid speed from the mentioned maximum value to a zero value.

The liquid velocity of C ₁ has a periodic course. The periodicity condition is met as soon as the liquid velocity at the beginning of PHASE I is identical to the velocity of the same liquid that corresponds to the end of PHASE II. The circuit C _{1 '} has a similar behavior. The system tends to automatically reach and maintain the dynamic equilibrium situation, since with each change in liquid velocity, the expressions p _cs and p _e that make up p _H are changed in the same way.

During operation, the valves in the same direction are always open, even in the presence of f _i <0, where i = 1, 1 ', 2, 2', which brake the liquid column in motion from E _i to U _i and therefore one in it Determine overpressure, which decreases from U _i to E _i , and makes suction easier.

The fluid velocity of the circuits C ₁ and C _{1 '} causes, in each of them, a delivery rate which, with every full revolution of the shaft of the number 4 cranks, is continuously changed from a zero value to a maximum value from which it decreases to go back to zero for a moment. The delivery rates of the two circuits phase-shifted by an angle  = 180 ° have an identical profile and their sum forms the delivery rate of the two-phase pump. The 180 ° relative phase shift of the two proportional delivery rates tends to compensate for the current delivery rate of the pump, the amount of which is subject to a maximum deviation of the order of 20% compared to the average amount.

In the above embodiment, the atmospheric pressure and the kinetic were not Energy of the liquid contained in the connection circuits is taken into account. Your presence is that the zero value of the above speed is greater than Is zero.

C.2) THE FOUR-PHASE PUMP

This type of pump has the task of maintaining the flow rate and consequently also a higher efficiency of the plant and a higher efficiency of the Intake system to get the liquid from the source.

The pump is called four-phase because there are four active circuits at its input are present, the inertial forces with a relative phase 0 = 0 °, 90 °, 180 °, 270 ° subject to.

Namely, it consists (see Fig. 8, 12, 14 and the corresponding descriptions) of two parallel, two-phase pumps, one of which is designed from a series of two identical, two-phase circuits, of which CB ₁ at the input and CB ₂ at the output is arranged; and the other pump from the series of two circuits identical to the previous ones, of which CB _{22 is arranged} at the inlet and CB ₁₁ at the outlet. The pair of circuits CB ₁ and CB ₁₁ is connected to the rotor R ₁ with the relative phase  = 0 ° with the above-mentioned modalities; while the pair CB ₂ and CB ₂₂ (see Fig. 14) is connected to the rotor R ₂ with a relative phase  = 90 °. In special cases, the four rotors R ₁ , R ₂ , R ₁₁ , R ₂₂ with relative phase  = 0 °, 90 °, 180 °, 270 ° are used, on which the circuits CB ₁ , CB ₂ , CB ₁₁ , CB ₂₂ (see Fig. 12) are attached.

In operation, the pressure generated by each two-phase pump is one instantaneous value, which is identical since each pump consists of a series of two identical, two-phase circuits, the identical accelerations subject to. As a result, the two, two-phase, pumps connected in parallel independent of each other.

Always in operation, in the interval  (0 °; 360 °) the mean value of the delivery rate is one each two-phase pump identical; however, their current value changes, due to the different phase at the input and the output, periodically such that the maximum flow rate of one of the pumps with the minimum value of the other pump is simultaneous. This balances the current one Delivery rate of the four-phase pump, equal to the sum of the two Funding services, such that the maximum deviation of the funding capacity from their mean value is on the order of 0.5%. The input and The output flow rate of the pump is therefore practically constant and moreover has they have an average value that is twice that of each proportion Pump.

This is a maximum of regularity in operation, a reduction in hydraulic losses in the circuits that are outside the pump and a Maximum efficiency of the intake system.

C.3) THE POLYFUNCTIONAL PUMP

It has the task of satisfying several requirements at the same time in order to Manufacturing and plant costs as well as the space requirement of the plant itself belittling.

With the current state of the art, there must normally be any need for Pumping work that is different due to the delivery rate or pressure or of the liquid to be pumped is the use of a different pump be provided.

With the proposed pump (see Fig. 12, 14 and the corresponding description), the problem can be solved very simply by the entire structural part of a pump, consisting of the support frame, the motor, the crankshaft, the crank rods, rotors and the corresponding rotary shafts are summarized; and, moreover, by fixing the two-phase circuits required for the necessary pumps, which are connected as described above, to the rotors, with the intended modalities, and by fixing the corresponding inputs E _ol and outputs U _{ol to} the support frame No. 1. In this way, the different pumps differ only because of the different hydraulic circuits. Of course, this is a perfect dimensioning of the various structural parts.

There is no doubt that the manufacturing costs and space requirements of the polyfunctional pump is very less than the sum of manufacturing costs and the space requirement of the separate pumps. The behavior is similar to that of one Current transformer with a primary circuit and several secondary Circuits that cost less overall and take up more space than Transformers dimensioned for identical voltages and powers were.

C.4) THE CONNECTIONS OF THE TWO-PHASE CIRCUITS AND THE ROTATING SHAFTS THE ROTORS

The input and the output of a two-phase circuit (see Fig. 12, 14) are both with the corresponding movable, attached to the rotor Connector connected using a hose to the corresponding fixed connector connected to the support frame is. The fixed connector can be the inlet or the outlet of the pump belong, or form an auxiliary connector that for the series with a Another two-phase circuit is provided that has a different relative Possesses speed.

The connection of the input and the output of a two-phase circuit is made by means of the connecting piece from FIG. 16) or from FIG. 17). The The connector consists of a main pipe and two secondary pipes. The Main pipe is formed by a straight part, which after a Axis of rotation of the rotor parallel path is curved such that its axis with the mentioned axis of rotation has a common point. He is after the curve connected with a hose connected to a fixed connector that is tied to the opposite side of the support frame. By the The main pipe flows the delivery capacity of the two secondary pipes of the connecting piece. These can have a common axis as in the connecting piece from FIG. 16) have, or they can be parallel and spaced, as in the connector from Fig. 17). The two secondary pipes are directly with the two entrances or with the two outputs of the two active circuits one two-phase circuit connected. The connector from Fig. 16) used for example for the inputs and the outputs of the circuit from FIG. 3); the connector from Fig. 17) is to be used for example for the Output of the two-phase circuit from Fig. 4), in which the outputs of the active Circuits have a distance.

In summary of the various statements above, the connection of the two connecting pieces carried out in compliance with the following rules: 1) the axes of the movable input and output connectors of the two-phase circuit bound to the rotor start in two levels, the opposite of the axis of rotation of the rotor and the axis itself are vertical; 2) the corresponding, fixed connecting pieces are on two opposite sides of the support frame bound and always possess coplanar axes perpendicular to the axis of rotation of the rotor; 3) one to the axis of rotation the vertical plane of the rotor contains the axis of the movable one Input connector, the corresponding axis of the fixed Connector and the axis of the corresponding connecting hose; the axis contains a different plane perpendicular to the axis of rotation of the rotor of the movable output connector, the corresponding axis of the fixed connector and the axis of the corresponding Connecting hose; 4) for ϕ = 0 (see Fig. 1) identify the axes of the two movable entry and exit connectors with the corresponding axes of the fixed connectors; 5) each one movable connector and a corresponding fixed Connector existing pair is connected by a hose; 6) The The course of the hose can be straight, curved with a single maximum value, or curved with multiple peaks.

Each hose is subject to the pendulum movement of the rotor Bending stresses of a periodically changing nature; however, it is missing Torsional stress.

The above connection is minimum stresses on the hose that maximum use of the available space and the absence of Interferences between the different components.

Figures 12) and 14) emphasize that the presence in the support frame of two Rotary shafts of the rotors has the following advantages: 1) the avoidance of Use connectors with bends at 180 ° to connect two two-phase circuits, with smaller hydraulic losses and smaller ones Manufacturing costs; 2) the arrangement of input and output of the pump on opposite sides of the support frame, rather than on a single side. The 'crank rod-crank' system requires a single crankshaft for the Pendulum movement of several rotors arranged on two parallel shafts; while the 'guided bearing' system requires as many crank shafts as that Swivel shafts of the rotors are. Therefore, the system is' managed warehouse only particularly advantageous with a single swivel shaft of the rotors.

C.5) Pendulum movement of the rotor generated by a 'guided bearing'.

An alternative system to the crank rod-crank system for generating a Range of vortex accelerations, suitable for the operation of the above pumps described.

The main components are (see Fig. 19): a) a rotor no. 2, which is on an am Support frame attached shaft 15 oscillates; b) a crankshaft No. 4, its axis is parallel to the axis of rotation of the rotor; it is connected to a motor on the side, runs on bearings attached to the support frame and crosses the rotor, whereby Avoid interference with other components; c) two cranks 5, the Bolt 7 is connected to the bearing 9, they rotate outside of the guides 45 and are also responsible for the eccentric masses of the bearing and the Balance crankpin; d) two parallel guides 45 which are rigid on the rotor are attached and arranged between the cranks. Between the guides the warehouse is interposed. The inner surfaces of the guides are ground and belong to two parallel planes, each from the axis of rotation of the Rotor is spaced by a length equal to the radius of the outer ring of the Bearing plus the tolerance that is necessary to allow the outer ring to run one tour independently of the other. This way it turns with each revolution of the shaft 4, the outer ring of the bearing alternatively on the one of the two guides with the same direction of rotation, by one to the rotor Pendulum movement is transmitted.

The points 0 ₁ , 0, 0 ₂ (see FIG. 19) belong to the parallel axes of the shafts 4, 7 and 15 in the order. The length 0 ₁ 0 forms the arm of the crank. The lengths 0 ₁ 0 and 0 ₁ 0 ₂ are dimensioned depending on the width of the angle ϕ _o , which was determined for the oscillating movement of the rotor.

The system described has compared to the crank-crank system the Advantage of a smaller space requirement and lower costs. There can be several Swivel rotors that are swiveled on a single shaft and is for a wide range of applications for the pumps described above suitable.
