If the components in question to form the Work equipment machine as in Pig. 7 in cross section and in FIG. 6 in front view with the front panel removed 6 are put together, it can be seen that a chamber, indicated generally at 80 in Figs. 6 and 7, between the periphery of core 46 and the flax of the opening 36 of the housing part 8 is formed is. It is also to be understood that the chamber 80 through the "flexible belt 70" into an inner work equipment working chamber 82 and into an outer working equipment working chamber 84 is subdivided, with working fluid connection between them through the Abdichtungwirirungen of the edges, of the flexible band 70 on the inner end surfaces of the front panel δ and the rear panel 10 is prevented in the world, as follows will be described in detail.

As in fig. 6 clearly shown, the riveted ends of the flexible band 70 are held essentially stationary in the holding opening provided for this purpose by the complementary arrangement of the cutouts 44 and 50 of the housing 8 and the core 46, respectively. DfcEgö * sa. £ performs drive rotation of drive shaft 14 in accordance with?

to 11B can be seen, in which the positions of the flexible belt 70 and the operation of the working medium machine for a complete revolution of the drive shaft 14 are explained. If it is assumed that the rotation of the drive shaft is 14 güsnäß Len Figure "11A to 11D in a counterclockwise direction as is indicated in the figures by arrows, and that the working fluid machine to be used as a liquid pump liquid from an inlet pipe 20 to an outlet pipe 22 and at the same time pumping fluid from inlet conduit 24 to outlet conduit 26, all of which are shown in FIGS is arranged to prevent fluid flow between each of the fluid passages or slots 38 and 40 and the outer working chamber 84; is. At this point, each of the working medium passages or slots 47 and 46 released from the flexible band 70 and is, accordingly, with the inner working chamber ^A rbeitsmiitelverbindung. Accordingly, when the drive shaft 14 rotates counterclockwise from the position shown in FIG. 11A by 90 ° to the position shown in FIG. 11B, the left part of the inner working chamber 82 is in contact with the bending movement of the flexible belt 70 of the area of opening 36 in contact with the periphery of core 46 is reduced considerably so that the liquid present in this inner working chamber portion can pass through passage or slot 48 in core 46 and from there through passage 34 in face plate 6 for delivery through delivery line 26 is pressed. This flow of liquid continues, of course, until the slot 48 passes through the flexible one

009830/111

Belt 7C is closed as shown in Fig. 11B is,

At the same time, the right part becomes the inner Working chamber 82 increased in volume, so that Liquid is sucked into it, through the 3ir, laßxeitung 24, the passage 32 and the slot 47. This bending movement of the flexible one also has an effect f. and it 70 to the effect of reducing the volume of the right part of the outer working chamber 84 in order to remove liquid to displace from this part to the left part of the outer working chamber 84 while at the same time the passage or slot 40 is exposed, thereby dispensing fluid from the left part of the outer Working chamber 84 through the slot 40, the attached Passage 30 and line 22 begins “Die Fliii33lgkeii3abga.be through the slot 40 through aich L'oet, if there is a drive pin 68 for more Moved 90 ° in the position shown in Fig. 11C, after which the flexible band 70 has covered the two passages or slots 47 and 48 to temporarily further flow of liquid through them prevent while the passage or slot 38 is released and a considerable increase in volume of the right part of the outer working chamber 84 is caused will result in a flow of liquid in these right part through the inlet line 20, the passage 28 and the slot 38 results.

Rotary movement of the drive pin 68 aua aoiner in Fi ^, IiC in the position shown in Fig. 11D position shown leads to substantially more complete All liquid is dispensed from the left part of the outer working chamber 84 through the slot 40 for delivery through passage 30 and delivery line 22 with subsequent closure of the slot 40 through the flexible belt 70 to prevent further fluid flow therefrom. Simultaneously

009830/111?

is caused by this bending movement of the flexible band 70.die in the upper part of the inner working chamber according to Pig. 11C to the left Part of the inner working chamber 82 according to FIG. 11D displaced while at the same time fluid communication between said part of the inner working chamber and the slot 48 is restored, whereby Dispensing of liquid through the latter and through passage 34 and outlet conduit 26 occurs. In addition, the flexing movement of the flexible belt 70 results in a position shown in Figure 11C into the position shown in Fig. 11D for a considerable increase in volume of the right part of the outer working chamber 84, so that additional liquid is sucked into this chamber part through the SehliU, z 38 is for subsequent displacement therefrom and discharge from the left part of the outer working chamber 84, if the drive pin 68 and the flexible belt 70 move from their position shown in Fig. 1ID in their move position shown in Fig. 11B.

When the flexible belt 70 is out of position in FIG. 11D α division shown in its shown in Fig. 11A When the position returns, a cycle of operation of the work equipment machine is ended with the Closing the slots 40 and 38, continuing the dispensing of liquid from the left part of the interior Working chamber 82 through slot 48 and with the release of the slot 47 through the flexible band 70 with a resulting increase in volume of the right part the one in the working chamber 82 in order to cause liquid to be drawn in through the slot 47.

It can thus be seen that the work equipment machine according to the invention when it is used as a liquid pump and its rotation energy over the drive shaft 14 is supplied, is double-acting in that it has two simultaneously effective working sections

009830/1 1 17

has, namely an outer working section which the slot 58, the outer working chamber 84 and the slot 40, and cut off an inner work, which includes slot 47, inner working chamber 82, and slot 48.

Alternatively, it should be understood that if a medium which is at a higher pressure than the medium to be pumped is appropriately introduced into one of these working sections, preferably into the inner working section through the slot 47 to prevent the flexible band 70 from collapsing inwardly according to the resulting force built up by the pressure differential to prevent the working medium machine according to Pig. 6 is eminently suitable for use as a motor-driven pump which is complete in itself. In particular, it should be understood that under such working conditions no rotational energy needs to be applied to the drive shaft 14, and that the introduction of the medium under higher pressure into the inner working chamber 82, for example through the slot ': - Mrcurcii, causes the inner working section al., the working fluid motor acts and flexing the flexible belt 70 through repeated working cycles as shown in FIGS previously arls result of the rotary drive of the drive shaft 14 has been described. Instead, a motor-driven compressor can be formed, in which case the outer working section is used as the compressor.

Another variation results when pressurized medium passes through each one in succession of slots 38 and 47 is inserted, resulting in formation

009830/111?

of a single-stage, double-acting work equipment motor leads to provide rotational energy for the drive shaft, which under such conditions according to Pig. is driven counterclockwise by flexing movement of the flexible belt 70 in FIG repeated cycles as shown in FIG. 11A through 11D are shown.

When using the working medium machine according to the invention (FIG. 6) as a working medium pump, as a compressor or working fluid motor, a step formation can easily be brought about in each case. if accordingly, the machine is to be used as an externally driven working medium pump, leads to a suitable connection the outlet line 22 with the inlet line 24, as shown in Fig. 5, of course to form a single-acting two-stage pump, the higher pressure in turn being maintained in the inner working chamber 82. Similarly leads when used as a working medium motor, suitable connection of the outlet line 26 to the inlet line for the formation of a single-acting two-stage central working motor, the higher pressure in turn being maintained in the inner working chamber 82.

A problem that arises when working sffii.ltelma3chi.no according to the invention as a compressor lies in the fact that the special housing chi it süö and core slots, which act as discharge valves in medium flow connection with the discharge lines, are caused by the bending movement of the flexible band 70 can be opened in order to release them before the working medium compressed in the relevant working chamber has reached sufficient pressure to enable it to flow out of the working chamber? To enable storage device in the manner of a recorded compressed medium. In particular, as shown in Fig. 12, in which the flexible belt 70 is in substantially the same position as in FIG. l is shown] ß, the compressed working fluid from the outer working chamber 84 to flow through the Abgaböleitung 22 to a aufgenomnifinen compressed working medium, as shown by R, Accordingly, when the flexible strip 70 of iioinem lower ¹ O t punk t Kent rum according to FIG , ΠΑ in the in ^ 'ig. 12 is moved in order to give the (rehäuijfischiitz 40 f ν οizeben, it may be that the working fluid in the outer working chamber 84 is not compressed enough to accept at least the pressure of the working fluid that is safely compressed in the cipeichar H goo, whereby an obviously ineffective backflow of compressed working medium from dom iipeichtjr R through the discharge line 2.2 and into the outer working chamber 84 takes place *

to prevent means in the working chamber 84, igt in Pig. 12, and this device comprises a check valve GV which is arranged in the discharge line 22 between the reservoir R and the outer working chamber 84 in order to make the occurrence of such backflow from the reservoir R essentially impossible and accordingly for maximum effectiveness the Ä _r fc _e i.tsmittelK: oinprimierung to ensure.

Alternatively, such a backflow of working fluid from the reservoir R can be essentially prevented by suitable design of the relevant shape of the housing opening 36 and the core 46, and by suitable determination of the effective length of the flexible strip 70 in order to ensure that the relevant core and / or housing slots, which act as ^a discharge valve or discharge valves, are only released and opened by the bending movement of the flexible band 70) when the working medium compressed in the relevant working chamber or in the relevant working chambers has assumed a pressure, which is sufficient to prevent such a backflow.

Modified embodiments of the compound of the land of the flexible tape 70 ala weiteere embodiments are illustrated in the £ ^l ig »9 and 10 ;. Like from B'ig. 9, the relevant tape ends are bent into a generally semicircular shape, as indicated at 90 and 92, respectively, and they are inserted into the relevant complementary cutouts 50 and 44 of the core 46 and the housing 8, whereupon a pin 94 is inserted between the ßingenden is used to set the ends of the tape within the hold opening thus formed. A particular advantage of this tape end fastening, which is described in i'ig. 9 is shown, lies in the fact that aie

009830 / 11It

allows certain freedom for rotation of the respective ring ends about the fastening pin 94, so that to a certain extent The extent to which tension or stress on the ring ends is prevented.

As shown in Fig. 10, the tape ends are simply bent at an angle of about 90 °, and a Complementary shaped slot, indicated at 96, is provided for this in the core 46, whereupon the appropriate Insertion of the tape ends so bent into the slot 96 results in the tape ends being relatively are arranged to the core 46 satisfactorily. A The particular advantage of this embodiment of the fastening of the ends of the flexible band is of course in the extraordinary simplicity that is evident is.

13 and 14 it can be seen that the housing 50 used in this embodiment has a considerably different shape than the housing 8 of the embodiment shown in FIG. In particular, the housing 150 has an opening 152 formed in it and extending completely eistreckt by a peripheral part of it. Similarly, the core 156 has a considerably different shape, although again it is complementary with respect to the opening 152 of the housing 50. In this embodiment, the flexible binding is kept discontinuous and, although it is again operatively connected to the drive pin 68 by being inserted into a drive pin slot 7B, it is directly attached to the core 156 at spaced locations. For this purpose, fastening pins 158 and 160 are provided, which extend through openings 162 and 164 provided for this purpose in the core 156, and the connection of the respective tape end to the bolts 158 and 160 is carried out by simply bending the tape ends around the pins and inserting the combination

from the pin and the end of the tape into the relevant core opening 162 or 164. Instead, any of the other described Working methods of connecting the ends of the flexible band with bolts are used here Tool passageways or slots 166 and 168 are provided which mate with the right and left, respectively Part of the outer working chamber 84 via trees between the relevant housing walls 170 and 172 and the relevant core walls 174 and 176 are in working fluid connection. Work equipment connection between the respective right and left parts of the inner working chamber 82 is created here by generally U-shaped passages or slots 178 and 180 formed to extend through core 156 in connection with the named working chamber parts.

When working, when counterclockwise rotation of the drive shaft 14, indicated by the directional arrow in Fig. 15, the passage 168 acts as an inlet to the outer working chamber 84, while passage 166 acts as an outlet therefrom and passage 178 acts as an inlet to the inner working chamber 82 and the passage 180 as an outlet therefrom. A particular advantage of the embodiment 15 resides in the fact that the particular designs used for the housing opening 152 and the Core 156 are chosen, larger voluma for the inner Working chamber 82 and the outer working chamber 84 are created, whereby the displacement of the working medium machine can be increased considerably. In addition, it is easy to see * that each passage 168, 178, 180 and 166 extends directly from the .Arbeitsmittelmaschine, which means work equipment from the machine directly to suitably connected inlet and outlet lines can be allowed to flow without calibration

009830/1117

Changes in the flow are required so that frictional losses in the flow are minimal. Since the respective passages 170 and 180 are furthermore arranged between the spaced-apart belt ends, it is made possible to increase the area of these flow passages considerably, thereby increasing the To further reduce friction losses when flowing with a resulting increase in the overall efficiency of the work equipment machine. How from ^ ig. 14 can be seen, of course, a V _O rderplatte '^ ^and a back plate 184 are provided which surround the housing 150 and the core 156, to provide the required formation of the dense inner working mitter working chamber and the outer working chamber "

JHe Ln Figo 15 shown work equipment machine has a largely similar design to that of the eaten 13 and 14, so that the same components are denoted by the same reference characters. In the embodiment according to FIG. 15 13t. However, it is easy to see that the Parts of the flexible bandea attached to the respective end of the band are adjacent, are curved to an even greater extent or degree around the adjacent core surfaces, thereby increasing the volume for the inner working chamber 82 and the outer working chamber 84 with it the resulting enlargement of the displacement of the in-line working machine. Slightly increased operation sbt; up ruchungen are a matter of course onto the flexible tape 70 by such? § magnification the required curvature of parts exerted by it, and it is to be understood that the extent in which the curvature can be increased, in view of on the enlargement of the displacement of the working medium machine and with regard to the enlargement of the degree of efficiency, of course, at least

is determined by the structural characteristics of the material used to manufacture the flexible tape 70 is used, as will be discussed in detail below.

The embodiment of the working medium machine according to FIGS. 16 to 19 shows a connection or arrangement of the Ends of the flexible band are adjacent to one another, while the shape of the housing openings of the core is slightly modified are to create greater displacement of the work equipment machine. In particular, this is Embodiment a holding slot 312 for the flexible Tape is provided which extends up into the core 46, while the housing 8 is a very sharp one upwardly extending portion 314 which extends into slot 312, with sufficient Clearance is left therebetween for the insertion of the tape ends. Preferably, although not necessarily, Here are the ends of the flexible strap 70 together prior to insertion into the strap retainer 312 bound. This design creates increased displacement by increasing the effective volumes the inner working chamber 82 and the outer working chamber 84, as described above in connection with the embodiment is described in accordance with Fig. 15, and in addition, there is the added benefit of the simplicity of tape end attachment achieved which is obvious.

For the purpose of making it clear that despite these sometimes major changes to the design of the G-ehäuseöffnurig 36 and dea core 46, the working of the Work equipment machine according to i'ig. 16 to 19 essentially is the same as above in connection with the working of the work equipment machine according to the 11A to 11D, it should be noted that when the drive pin 68 is in the position shown in FIG reproduced position, which is essentially the

009830/1117

is top dead center, each of the core slots 47 and 48 is closed by the flexible tape 70 and each housing slot 38 and 40 is opened by the flexible tape in the same manner as shown in Fig. 1IC that when the Drive pin 68 is in the left position shown in Fig. 17 between its upper and lower dead center position, the housing slot 40 and the core slot 47 are closed by the flexible belt 70 and the core shiitζ 48 and the housing slot through or thereby in the same way as with B _eZ ug top of Fig has been described 11D are open, that when the drive pin is, 68 is in its lower Totpunkteteilung as shown in Fig. 18, the housing slots 38 and 40 are closed and the core slots 47. and 48 are opened in the manner described above and with reference to FIG. 11A, and that when the drive pin 68 is in its right-hand division between s 19, the housing section. 38 and the core slot 48 are closed by the flexible band 70, the core slot 47 and the housing slot 40 are opened by the band in the manner as described above with reference on Fig. 11B. Accordingly, it can be seen that the operation of the working medium machine of FIGS. 16-19 is essentially the same as that described in detail above with reference to FIGS. 11A-11D.

It is interesting to note that when designing the housing opening and the core, as shown in FIGS. to 19, the displacement of the working medium machine can be increased by about four times compared to a work equipment machine Housing opening shape and core shape as shown in

009830/1117

Pig. 6, and that it has been determined that this very substantial increase in displacement can be achieved without significantly increasing the operating stresses on the flexible sand 70 during operation of the working equipment machinery. The main factor which enables this considerable increase in the volume of the machine "lies" in the fact that the radius of the crankpin rotation of the working medium machine has no detrimental effect on the necessary bending effect of the flexible band due to the onn of the housing opening and the shape of the core according to Jf ¹ xg, 16 to 19 can be made a & a two-three times larger, as in the case of the Perm der! Haste according to Pig. 6 can be achieved

In all of the guiding forms of the working machine according to the invention, which are described above, it is to be understood that the displacement ratio between the outer working chamber 84 and the inner working chamber 82 is somewhat. 1: 1, namely for any basketination of housing opening, Kerjjgeatalt and shape of the biegsaaieii band, and that this conception is prescribed to the basic displacement ratio of 1 "1 duroii the r.llgsiEfiiii circular cream, dir * with movement of the BcindantTiehsbolaens ode: · ⁷ der IbIj ¹ JGtsebuchee5 jenscndeiii wj.e gf. the fs.21 ipt _s b @ £ cliriebsri will »ώ @ result see ksin ProblGE- Ci-T ^": öiesfe Verßi'ariäiiijungsbäitnigkungverhäitnigkungverhäitnigkung Ή 1.

operates, which is preferred for reasons explained below will.

20 shows an embodiment in which the displacement ratio between the outer and inner working chamber can range from about 1 to 0.5 s 1, so that it is suitable for use as a two-stage compressor. In particular, as in Pig. 20 can be seen, in which the housing with 500, a ± e housing opening asit 5C2, the core with 504 and the flexible end with 506 are designated, the arrangement of drive shaft and drive pin or drive bushing, which was previously used to generate energy from the The flexible tape is replaced by a lever 508 slidable in a dedicated slot in a pivot pin 510 and pivotable within generally wedge-shaped slots 512 and 514 formed in the core 504 therefor. It goes without saying that the pivot pin 510 is disposed in the core 504 to prevent the flow of working fluid from the wedge-shaped slot 512 to the wedge-shaped slot 514.

The flexible band 506 is attached to the lever 508 near one end thereof by passage through one Slot fastened in a fastening bolt or connecting bolt 516, of course with freedom mounted in lever 508 for rotation. A circumferential cutout 518 is in the lower part of the housing 500 is provided and a conventional crankshaft assembly, shown generally at 520, is adjustably arranged therein and connected to the lower end of the lever 508 to put it on a generally circular path with the result that the drive pin 516 is in the opposite fiichtung is driven so that it is a general elliptical orbit describes how it is interrupted by the Line 522 in FIG. 20 is indicated.

009830/111?

If thus, as shown schematically in Fig. 21, the lever 508 is located in the slot in the pivot pin 510 so that about 3/4 of the effective Length of lever 508 is above the bolt, and when the lower end of lever 508 is on a generally circular path is driven, as indicated at 524, by the appropriate arranged crank wheel 520, the drive pin 516 is on a generally elliptical Bahr « 522 driven with the result that the displacement of the outer working chamber 84, represented by the Area in Fig. 20 between the broken line and the area of the housing opening 502, about three times as much as great as the repression of the internal "working Camia" is represented by the surface in FIG. 20 between the belt 506 in the illustrated position and the Perimeter of the core 504. Bs is thus clear that when used of the housing slot 528 as - ^ working medium machine inlet slot, the connection of the housing slot 530 to the core slot 532 for the step arrangement and the utilization of the core slot 534 as a working medium machine outlet slot for the working medium machine 20 and 21 used extremely satisfactorily as a two-stage compressor can be.

Fig. 22 shows that the lever 508 in the pivot pin 510 can be adjusted with accompanying Adjustment of the position of the crankshaft 520 in the housing cutout 518 to a working chamber displacement ratio of about 1: 1, whereby the work equipment machine according to FIG. 20, for example, as two stage pump can be used. 23 shows a position of the lever 508 and the crankshaft 520, in order to create a working chamber displacement ratio of about 0.5: 1 for the use of the working equipment

009830/111?

machine according to Pig. 20 as a double-acting, single-stage metering or measuring device. Further, since a range of ^A rbeitskammerverdrängungsverhältnissen in the embodiment of Pig. 20, the working fluid machine can be used very satisfactorily as a metering or metering device in which any of the available working chamber displacement ratios can be conveniently selected.

A modified version of the connecting device for producing the drive connection between the flexible belt and the drive shaft of the working medium machine is in the Pig. 24 and 25, and, as best from Pig. 25 , the drive shaft 14 ends in this example in a crankshaft structure with a crank, the structure being formed by a first crank crank, which can serve as a bearing 216, which is mounted in the rear plate 10 as shown, a second crank crank which as warehouse 21 :. service; can, which, .sie shown, is mounted in the front plate €, and a crank pin or drive pin 220 is shown, which connects the cranks together. In this embodiment, a bushing 222 is rotatably arranged around the crank pin 220 so that it can rotate freely relative to the crank pin 220 when the drive shaft 14 rotates. In addition, bearings can of course be provided in the front plate 6 and the rear plate 10 for the drive shaft 14.

Around the flexible band 70 with this embodiment to connect the drive shaft arrangement, igt the flexible tape TC as indicated at 224 is, cut out at the Uofang of the drive bushing 222 and additionally designed, generally semi-circular

009330 / »11?

circular band fasteners 230 and 232 are formed at respective ends thereof and are arranged around the resulting assembly of flexible band 70 and drive sleeve 222 as shown, after which fasteners in - ^ orm of spaced rivets 234 through therefor in the mounting flanges and openings provided in the flexible strap and proximately secured or secured in the opening to complete the connection of the flexible strap 70 to the drive sleeve 222. Accordingly, it can be seen that as the drive shaft 14 is driven, the crank pin 220 and drive sleeve 222 are driven to describe a circular path about the center of the drive shaft 14, with the drive sleeve 222 rotating toward the center of the drive shaft 14 and with the drive sleeve rotating rotates about the crank pin? 20 to the extent necessary to produce the required flexural movement of the flexible band, as previously described in connection with FIGS Connection with the said F'jgures is described. Instead, it is easy to see that driven bending movement of the flexible belt 70 by pressurized working medium when the machine is used as a working medium motor understandably leads to the drive shaft 14 being driven by the drive pin 220. A particular advantage of this mode of operation of binding the flexible tape and the drive device is the fact that the stresses on the flexible tape are somewhat relieved, either on a somewhat larger area or on something Larger area of the belt ends 230 and 232 are distributed southward, which is obviously not clear.

Fig. 26 shows a generally similar connection of the flexible belt and drive mechanism for the flexible belt, in which a single generally integral connector 236 is provided and aligned with the upper portion of the drive sleeve 222 by up-line fasteners by Ui et en 236 is securely attached in order to press the ο βnacht-arten part of the flexible -Bandes 7ö securely between the Anüriebscuchste 222 and the Befeatigungsteil 236 in the manner shown. As described immediately above in connection with the connection of the flexible belt and the drive device for the flexible belt of the embodiment according to FIGS. 24 and 25, the connecting device according to Pig. 26 again the ^v orteil that the contact area is maximized in size between the flexible belt and the drive device for the flexible belt so that the are on the strip during operation of the working fluid machine au ag eübten stresses minimal.

A flexible band 70 with a slightly different shape and a somewhat different method of tape end connection which is convenient and convenient adjustment the effective length of the tape 70 are shown in FIGS. As shown there, the opening 36 in the housing 8 and the core 46 again have a generally complementary shape, but terminate they each at their lower J% de in a general wedge-shaped shape. In this embodiment, a tape retention slot 300 is provided, which extends from the lower end of the housing opening 36 extends completely through the housing 8 to the lower end / ί and a conveniently removable plate 302 is provided to complete the tape retention slot 300 and the required Maintain working fluid tightness of the inner and outer working chambers 82 and 84 *

As shown in Fig. 28, the flexible belt 70 used in this embodiment also terminates in an essentially k ^ egg-shaped lower end and the fastening of the strap ends can thereby be conveniently carried out caused to fall into the tape holding slot 300 can be used in housing 8. A particular advantage of this design lies in the fact that convenient and convenient adjustment of the effective length of the flexible band 70 is enabled. The setting can be functional and convenient by simply removing it

of the plate 302 and manipulating the relevant tape ends further into the holding slot 300 or be made out of it.

The creation of the possibility of convenient and appropriate adjustability of the effective length of the flexible band 70 enables the adjustment to compensate for manufacturing tolerances and furthermore enables convenient modification or change of the total tension exerted on the flexible band 70, so that the adjustment of the sealing force or closing force is provided, the rbeitsmitteldurchgänge or of the flexible belt 70 during the closing of the relevant ^A slits 38, 40, 47 and applied 48th That is, if the effective length of the flexible tape 70 is increased by moving the tape ends in the tape holding slot 300 upward as shown in Fig. 27, the force exerted by the tape enclosing said slots is increased, while reducing the effective length of the tape by moving the tape ends in the holding slot 300 further down, of course, leads to a reduction in the sealing force.

A means of providing adjustment in the effective length of a generally heart-shaped flexible ribbon while the working medium machine is in operation, FIG. 29, and at this point reminded of it will that by creating the possibility of

009830 / 11It

Division of the effective tape length a compensation or an equalization for manufacturing tolerances is possible and easy adjustment of the sealing force of the tape against the housing and core slots is enabled.

In Fig. 29, the housing at 460 ″ is the housing opening with 462, the core with 463, the housing and core slots with 464, 466, 468 and 470 and the flexible one Band labeled 472. The tape ends are attached to a rivet or rivets 474 is attached to the flat bar 476 and the resulting ribbon-end-bar assembly is general in itself radially extending slot 47ε used, which is in the Core 463 is formed. A leaf spring 480 is also arranged in the slot 478 and it presses against it the adjacent ends of the pliable band 472 and the rod 476 to bias it radially outward of the slot 478, while an adjusting screw 482 calibrated through a complementary threaded opening 484 formed in housing 460 into contact with the opposite end of rod 476. Accordingly, the position of the rod 476 in the housing slot 478 and, accordingly, the effective length of the flexible belt 472 during operation of the working medium machine can be easily adjusted by simply turning the adjusting screw 482. A special Advantage of providing the adjustment of the effective length of the flexible belt during the operation of the Arbeitsmitfelmaechine lies in the fact that concerned Operating parameters of the machine are measured and observed and brought to the desired values, simply by turning the adjusting screw 4G2.

When executing the work equipment machine according to Referring to Figures 30-32, the flexible band, herein generally designated 304, includes a first band portion and a second strap portion 308, each of which is preferably

009830/11 M

is pretensioned in such a way that, before installation in the working medium machine, it is the one shown in FIG. 32 Takes shape. It is installed by inserting the upper ends of the band members 306 and 308 into one Slot 78 in the drive pin 68, and by inserting the lower ends of the tape part in a tape holding slot 310, which is at the lower end of the housing opening is formed. In addition to the advantage that easy adjustability of the effective length of the flexible Band is created, as it was immediately before in connection with the * 'ig. 27 and 28 have been described is, creates the B ;. nd execution ingenious? the pig. 30 to the additional advantage that the belt is stressed at the point where the belt is connected to the drive pin 68, i.e. at the tape holding slot 78, is reduced to a minimum, and that the tape parts and 308 can be manufactured more easily, since of course they are simply manufactured as straight bundles as shown in Fig. 31 and then biased so that the · assume the shape shown in FIG.

A somewhat different way of making the flexible band and fixing the ends of the building is described in FIGS. 33 to 35. As best seen from Fig. 35, in this example, although the housing, the G _o home mouth and the core has a Gestaltihaben, which is substantially similar to the above in Verbiiiäuüg with Fig. Shape described 6, the flexible strip 320 of zeietückjger embodiments and umiaßt a band portion 322 and a Bi .ndtei3 324. As shown in FIGS. 3 3 and 34 can be seen, the lower ends of the band portions 322 and 324 fixed between nem housing 3 and the core 46, respectively, using Fastening bolts 326 and 328 which are inserted into openings through the 3 fcäuses and the complementary

are formed. Attaching the Bar.dender, ar dan Befsstigungsbolzen is performed at phrases example, by simply bending the strip end around the pin in the apertures, as shown in -Fig "34 Clear, thereby somewhat i'reiheit for rotation of the Bandenien. relative to the fastening bolts, whereby at the same time a reduction in the amount of stress on the strap is achieved during operation,

Fastening of the upper ends of the belt section to the drive socket 68 is provided by the freely rotatable arrangement of a fastening bushing 330 for the flexible belt, which has fastening flanges 332 and 334 around the drive pin 66, and by connecting the upper end of the belt section 324 between the Befeatigungsflanschen by a plurality of fasteners in * 'orm of rivets 336 on dia Wsiss, as best seen in the ^x' ig. 35 and. 36 shown is »Generally semicircular strap attachment parts 338 and 340 are arranged such that they can rotate around the strap attachment parts 330, and the strap attachment parts can have attachment flanges 342 and 344 so that the slack of the upper end of the strap part 322 to the drive pin 68 is clearly visible. In this embodiment, the belt parts 322 and 324, which form the flexible belt 320, are freely rotatable or freely pivotable at any point of their connection, whereby the operational stresses exerted on the flexible belt 320 during operation of the working medium machine are considerably reduced. As a result, the band members 322 and 324 forming the flexible band 320 can be formed of much thicker and stronger material than they could be formed if they were rigidly connected at their points of attachment to the drive bolt and dsm housing and core would be, so that the - ^ rbei ^ ssittoi machine according to the invention with higher He

008830/111?

can be driven, due to the greater strength of the flexible belt, which is increased by the Thickness of the tape is created.

I ¹ Ig. 37 shows the use of a flexible strap 320 constructed and secured as used in connection with FIGS. 35 to 36 is described in a Arbeitsmitteliaas chine, in which the housing opening and the core have a shape as shown in the. 16 to 19 is described, while FIG. 38 shows the use of a flexible band 320 in a working equipment machine, with the housing opening and core having a shape as in the embodiment according to Pig. so that it can be seen that the two-piece belt design shown in FIG. 33 can also be used in equipment machines which have differently designed housing openings and cores. That is, for example, that in the embodiment of Fig. 37, the substantial benefits of reduced operating stress on the flexible strip, created by the use of the flexible B _a ndes 32C, and considerably enlarged displacement created by using a shape for the housing opening and core according to the representation , are combined, while the execution according to -k'ig. 38, in addition to providing the combined advantages of the embodiment according to FIG. 37 /, has the additional advantage that a considerable increase in the flow areas or flow areas of the core passages or slots 178 and 180 is made possible, as was previously described in connection with FIG.

As mentioned above, the strength of the flexible The band can be conveniently enlarged for -working the machine under higher pressures without reducing the Flexibility of the tape or increase in the operating stresses exerted on the tape, by

009830/1117

Forming the tape in multiple layers. Accordingly, the flexible belt shown in FIG. 39, generally circular in shape and designated 440, may include belt portions 442, 444, and 446 that are in face-to-face contact with one another and connected to a drive sleeve 448 by a fastener 450 and rivets 452 are, so that a three-ply flexible B is provided with _a nd obviously considerably increased strength. For example, the ends of the ribbon 440 can be bent, as shown at 454, to be placed in a ribbon retention slot as described above, and the ribbon ends tied together if desired.

Fig. 40 shows an essentially identical multi-ply tape design in which the tape is gored in a heart shape, with like reference numerals being used for like parts of the band. Additionally, Fig. 40 shows that a fastener rivet 456 can be passed through the tape portion ends for an obvious purpose. The manner of fastening of the multilayer tape may in principle which is as described above and shown in Figs. 8, 24, 29 _f 30, 33 and 35, for example, be the same as for single-layer tapes.

Fig. 41 clearly shows that they relate to each case. In belt portions 442, 444 and 446 essentially are arranged in surface contact. Figure 42 shows that the three-ply flexible tape 440 is alternatively can be connected to the drive pin 68, v.obei it is believed that the bolt 68 is rotatable in the shaft through the passage of the belt a band mounting slot 76 in the bolt and by subsequently inserting a rivet 458 < Ba has been determined that at the circular shape

From Fig. 43 it can be seen that there is no separation of the hinge parts has occurred during the bending of the strip which arises during the Arbeitene the working fluid machine, said multi-layered tape 440 is deformed from the generally circular shape 440 'to a generally oval shape 440 ¹¹ . This £ is ensured that the County ^ eänderungen the hinge parts substantially cancel each other, as can be seen from the figure.

However, there may be slight sliding movement between the contact surfaces of the belt attachments 44 2, 4, 44 and 446, and the friction losses caused by such sliding movement can conveniently be kept to a minimum by applying a suitable lubricant, for example in the form of a graphite or molybdenum compound, to the Contact surfaces of the B; .ndteile is applied.

Referring to Figures 44 through 48, there is shown a modified form of aforin of the flexible tape which provides improved sealing of the tape edges relative to the inner face of the faceplate and backplate. This embodiment has a flexible bend, since it is formed from three different tape parts, ie an outer tape part 200 and inner tape parts 202 and 204, which are arranged in terms of their work as shown in FIG. The outer band part 200 has a width that is slightly smaller than the distance between the frontal face of the front plate and the shepherd's plate, while the combined widths of the inner end parts 202 and 204 are just slightly smaller than the length of the tree mentioned.

For the purpose of keeping the outer edges 206 and 208 of the inner banate parts 2u2 and 204 in substantially secure surface contact with the end face 201 of the front plate and the end face 203 of the rear plate, spaced apart tongues 210 are cut out of the inner edge 212 of the inner end part 202 and bent outwardly, whereby when the band parts are assembled in the manner shown in FIG. 48, the tongues 210 press against the adjacent inner edge 214 of the inner band part 204 with the result that the. Edges 206 and 208 of the outer band part are pressed into reasonably secure surface contact with the end face 201 of the front panel and the end face 203 of the rear panel, so that essentially working fluid-tight seals are maintained between them and there is leakage of working fluid around the combined band structure between the inner one Working chamber 82 and the outer working chamber is prevented so as any reduction in the efficiency of the machine due to such leakage is avoided. Although the amount of play, if any, created between the edges 206 and 208 of the outer band member and the faces 201 and 203 of the front plate and back plate, and the amount of backlash, dsi * of the spacing is caused by each other, changes with the application of the work equipment, in a typical instruction of the work machine of the invention when pumping fluids, an oepi ^ l of about 1/1000 of an inch between the edges of the small parts and the end faces of the Front plate and rear plate approved sain and the Sohaffuag eiu.es printing of about 1/2 bia to 1 lbs (0.454 kg) ha-; see proved particularly satisfactory ^

The use of a flexible belt cooling device such as that shown in Figs. 50 to 53 and is shown is of particular importance when using the work equipment machine according to the invention ale Compressor with a high compression ratio or pressure ratio. That is, although cooling of the housing part a and the front plate and the rear parts of the working equipment machine can be conveniently caused by that coolant channels are formed in these parts and / or cooling fins on their, it is to be understood that the flexible band on both sides, i.e. in the outer working chamber 84 and the inner working chamber 82 dem is exposed to high delivery pressure and accordingly very

will heat rapidly unless provision is made to cool the belt, which will result in a decrease in the strength of the flexible belt and a decrease in the life of the belt. Accordingly, it can be seen that it is desirable to provide cooling for the flexible belt, particularly when using the machine according to the invention as a high compression ratio compressor, it being understood that the width of the coolant passages for the flexible belt, namely the wide ^one Passage in Fig. 51 and passage 420 in Fig. 54, in each case is determined by the particular volume and flow rate of coolant considered necessary to maintain the flexible belt temperature at a predetermined level.

The particular cooling medium used can be a liquid or a grass and it can be in any of the both cases continue to exercise a lubricating and sealing function. Thus, when the coolant is OeI, it is to be understood that by maintaining the pressure of the oil in the coolant passage for the flexible tape a slightly higher value than the delivery pressure of the working medium machine working in this case as a compressor a small amount of OeI through the clearance between the edges of the band portions and the inner surface the front panel and the rear panel is pressed to form a film therebetween which is more satisfactory and advantageously a lubricating and sealing function in addition to the function of cooling the flexible belt, depending on the particular The working medium machine working here as a compressor can also be used satisfactorily with water if necessary and can be used advantageously for cooling the flexible belt, for lubrication and sealing.

009830/1117

If a gas under suitable pressure is used as a refrigerant, it can be seen that leakage of ^ as into and through the clearances between the flexible band and the face of the front and rear panels can act to jam therebetween parts wLrd formed, so that the flexible B is _a nd lubricated and sealed and the! friction losses of the working medium · machine be reduced to an absolute minimum.

Reference is now made to the multi-unit work equipment machine according to FIGS Pig. 55 and 56. These figures show » that the components of the working line are of the same kind or an extraordinarily similar design as the components of the machine according to #ig. 1 to 8 are so that the same references are used as far as possible. In this embodiment, as on Best seen in Fig. 55, essentially two Arbeitsmittelvorricht'.sgpn provided, the Büekseite at the rear to enable ^ that four different Pump ™ and / or sealing functions at the same time can be exercised.

which also serve as a bearing for rotation in suitable openings, which for this purpose in the common Rear panel 10 and are formed in the front panels 6a and 6b.

In this embodiment, drive rotation of the drive shaft 14 results in each crank pin or drive pin 100, 102 describing an approximately circular path, the center of which coincides with the center of the drive shaft 14. The flexible bands 70a and 70b are driven bolt here preferably _n with A and 102 connected so that -fc'reihiet is provided for rotation between them in the manner as has been described above in connection with FIGS. 24 to 26.

Although not fully shown, like the face plate 6 of Figure 5, the face plate 6a includes work fluid lines 20a, 22a, 24a and 26a extending therefrom in substantially alignment with work medium passages 28a, 32a and 34a extending in the face plate 6a and the housing part 8a has as G _e casing part 8 according to Fig. 5 radially extending working medium slits 38a and 40a. In a similar way, like the core according to FIG. 5, the working medium slots 47a and 48a extending generally radially inward, so that working medium connection between the front plate passage 28a, the housing part slot 38a, between the working medium passage 30a of the housing part 6a and the slot 40a of the housing part 8a, between the working medium passage 32a of the front plate 6a and the slot 47a of the core 46a and between the working medium passage 34a of the front plate 6a and the slot 48a of the housing 8a. Similarly, fluid connection between the passages 28b, 30b and 34b of the V _O rderplatte 6b and the slots 38b

and 40b of the housing part 8b and the slots 47b and 48 b of the core 46 b created.

This embodiment creates two different working medium machines which, although they are driven by a common drive shaft 14 by means of the crankshaft having two cranks as described above, each have two different inlet lines and two different outlet lines, so that it is possible, if desired, to carry out four pumping or compression processes at the same time. Instead, a staged arrangement of these four different pumping or compressing operations can be conveniently created by appropriately connecting one or more pairs of the inlet and outlet conduits. Use of the working equipment machine according to ^J ig. 55 and 56 as Arheitsmittelmotor as üombination of working medium motor and pump or working fluid motor and compressor can be easily obtained in the manner as described in ^Getting Connected up with the working fluid machine of FIG. Has been described. 6

A particular advantage of the embodiment of the Invention according to the I'ig. 55 and 56 is in yours . reduced weight because the two work equipment machines are created on a common rear panel 10, and in the reduced space requirement, which arises from the same reason. In addition, there is a machine simplification with regard to the drive or output possible because everything that is required to generate the driving force between the machines transmitted, or to take power from the machines, is to add the crank portion 106. Step formation and step arrangement can of course easily be achieved in this embodiment caused that the outlet and inlet connections are made in an appropriate manner.

A flexible strap 70 is in each housing opening 112-122 arranged so that it surrounds the core arranged therein in the manner described above, and a slotted Drive pin 68 is near the perimeter of common drive plate 144 for drive connection with each of the flexible straps 70 as described above arranged. Accordingly, it will be understood that driven rotation of the drive shaft 14 will result in it being isolated Drive pin 142 and common drive plate 144 describe a generally circular path around the flexible band 70 connected to it by the

009830/1117

the following positions to drive, as previously in connection with the Pig. 11A to 11ü have been described is. Since in this embodiment of the invention the between the outer surfaces of the flexible bands 70 and the surfaces of the Grehäuseöffmangen formed outer Working chambers 84 through the centrally arranged drive opening 124 are connected to one another, they are not used for pumping or compressing work equipment or used for driving the shaft 14 when used as Arbeitsmittelmotr, and instead of which it is only cores 126-136 that are used to perform these functions.

If the counterclockwise rotation of the drive shaft 14 is assumed, as is indicated by the arrowhead in FIG with an A.

In addition, the work equipment machine according to FIG. 57 is special adapted for use as a working fluid motor that creates an extraordinarily high output torque Via the drive of a common shaft by means of six different work equipment engines.

In the embodiment according to FIGS. 58, 59 and 60, the front panel is designated with 240, the housing part with 242 and the rear panel with 244. Of the In this embodiment, housing part 242 has a plurality of openings 246 which extend completely through extend through it and at a distance from one another in an arc-shaped manner around the center of the housing part 242 are arranged in a manner as described above in connection with the housing openings 112 to 122 of the Embodiment according to FIG. 57 has been described. A core 248 is disposed in each housing opening 246 and each li-erri has two spaced apart generally radially extending working fluid slots 250 and 252, while similarly two spaced generally radially outwardly extending slots 254 and 256 therein Housing 242 are formed which extend through the housing 242 in working fluid communication with each of the G house openings 246 extend.

A turn designated 70 flexible strap is in each G _e h.ruseöfinung around 246 disposed about the core disposed in this opening 248 and is fixed in each case between the core and the housing, as indicated at 258th In a manner similar to that described above in connection with Figures 5, 6 and 7, working lines 260, 262, 264, 268 are provided which extend from the faceplate 240

Each working medium line 260 is in working medium connection with a housing slot 256, each auxiliary medium line 262 is located in Work equipment connection with a housing slot 254, each working medium line 264 is in working medium connection with a core socket 252 and each working medium line 268 is in working medium connection with a core slot 250.

Its common drive mechanism for the flexible ones Ribbon is shown generally at 270, and it is effective to create flexible ribbons 70 in the six housing openings in the embodiment according to FIGS. 58 to 60 to drive simultaneously or to be driven by these at the same time. The common Drive device 270 includes a drive shaft 14 extending through aligned openings in the front panel 240 and the rear panel 244 extends. A middle gear or sun gear 272 is at the end of the Drive shaft 14 attached to the outer end face of the front plate 240 adjacent. Sin drive pin 274 extends through aligned openings in front panel 240 and rear panel 244 through each of the housing openings 246 near the inner end thereof, and each drive pin includes an enlarged tape drive portion 276 formed on it in a manner as best shown in Figs is. For use with this type of drive pin, the flexible belt 70, as shown in FIG. 3, is suitable. 29 and 59 clearly shows a unitary drive bushing 278, which with reference to the enlarged Drive part 276 of drive pin 274 has a complementary size. Accordingly, the required Anxriebsver-

binding between said drive pin part 276 and the flexible band 70 comfortably in each case by inserting the enlarged drive member 276 the unitary band bushing 278 with freedom for rotation between them.

Driven rotation of each of the drive pins 274 from the sun gear 272 occurs in the embodiment of FIGS. 58 through 60 by creating a Planet gear 280 at the end of each drive pin 274 near the outer end face of the face plate 240, and by meshing each of the planet gears 280 with the Sun gear 272, so that it can be seen that driven rotation of the drive shaft 14 to driven rotation of each drive pin 274 with resulting Performs work of the work equipment machine according to this embodiment. It is interesting to note that, because in this embodiment of the work equipment machine an externally arranged common drive device is provided it is possible to open each housing opening 246 to be kept separate from the rest of the work equipment complete what is contrary to the embodiment according to Fig * 57 is, in dar the housing openings are connected by a general central housing opening 124. In the embodiment according to 58 to 60 it is therefore possible to use both the outer working chambers 84 and the inner working chambers 82 of each working chamber 80 to use. Accordingly, it can be seen that when the construction of the work center machine shown in FIG simultaneous execution of twelve work equipment pumps or Vefdichtungsvorrichtungen is made possible, where 'weight and tree are saved at the same time. Alternatively it can also be seen that the stage circuit or stage arrangement can be conveniently implemented by means of suitable external line connections can be effected. Accordingly is a

009830/1117

A wide variety of combinations of working medium engine, Working medium pump and working medium compressor are possible with the design according to FIGS. 58 to 60. Farther can be a tool engine with an extraordinarily high Torque can be conveniently created in that each of the twelve working sections is used as a working fluid motor.

The working means machine according to FIG. 61 is essentially identical to the embodiment according to FIGS. 58 to 60, with the exception that in the latter the planet gears 280 are of different sizes, so that the relevant housing openings 246 are necessarily at different radii or at different distances from the The center of the housing 242 can be positioned in accordance with the particular size of the planetary gear used to drive the flexible belt concerned. As shown, the design can 51 an embodiment of six work equipment machines 2 ^ 2, 284, 286, 288, 290 and 292 can be created, each of which has a different volume capacity. Accordingly, in the "embodiment according to FIG. 61, in addition to the advantages previously specified in connection with the embodiment according to FIGS. 58 to 60, the advantage is obtained that it is particularly adapted as a device for mixing or proportioning of working materials The drive bolts of the working medium machines 282, 284, 286, 288, 290 and 292 are rotated at progressively higher speeds in the embodiment shown. Accordingly, since the delivery volumes differ in fixed proportions, depending on the sizes of the planetary gears 250, these parameters are realized by means of a suitable working medium machine design to create a device for mixing and proportioning working media, which is extremely suitable for large

009830/1117

To proportion or measure and mix a large number of work equipment very precisely.

In addition, the work equipment machine creates according to 61 shows the possibility of being used, for example, as a six-stage compressor. The single Work equipment mastline with the smallest planet gear would be the first stage with the greatest displacement because of the highest speed, while gradually the work equipment machines with the larger gears have smaller displacement in writing, as is necessary for multi-stage compressors.

A slightly modified embodiment of the invention, in which the housing slots and core slots merge to form common inlets and outlets for the to create inner and outer chambers and accordingly a single-stage double-acting work equipment machine is shown in FIG. 62. In this figure, the housing is denoted 530 and the core is denoted by 532. Between the housing 530 and the core 532 trees and 536 are provided, which emerge from the work equipment machine extend and the inlet and outlet slots according to the preceding Create description. Each of these slots is in working fluid connection with the outer working chamber 84 and the inner working chamber 82.

For the purposes of explanation, the flexible belt 70 is shown as bolt daß'es gear _n with the A and fastening bolts 326 and 328 connected such as' ig above in connection with the £. 34 and 36, it being understood that this type of connection of the flexible belt with connecting pins is only one exemplary embodiment of this connection and that the other modes of operation described above for connecting the flexible belt are used instead can.

If - the machine components are arranged as

009830/1 1 T-7

it is shown, and when rotation of the drive shaft in Gf eg enuhr pointer direction, as indicated by the. Direction arrow is indicated, assumed, the slot or space 534 acts as a common inlet for the outer working chamber 84 and the inner working chamber 82, while the slot or space 536 as a common outlet of the outer and inner working chambers 84 and 82, respectively. In every other way is the way of working 62 of the mode of operation of the machine according to FIG. 62 is essentially identical to that described above in connection with, for example with the fig. 16 to 19 has been described.

A particular advantage of the embodiment according to Flg. 62 lies in the fact that with her the occurrence of Puibsationen or pressure surges or sudden Work equipment accelerations and work equipment delays in the inlet lines and the Outlet lines is prevented to a large extent. under Reference to fig. 16 to 19 is to be understood that in certain applications the one shown there Working equipment machine, for example when ragging liquid at high speed during each Rotation of the drive shaft 14 occurs a period during which all slots 38, 40 »47 and 48 through the flexible band 70 are completely closed, 30 that a sudden delay in the column of liquid in the relevant connected inlet or outlet is caused, the deceleration being a sudden acceleration of the liquid column at subsequent Reopening the slits through the flexible tape follows. Research has shown that such sudden accelerations and decelerations of the liquid column in the inlet line of a working equipment machine can lead to cavitation with the resulting loss of effectiveness and / or Leadership roaion, and that such sudden orders

O0983Q / 111?

settlements and delays in the outlet line of a Working equipment can lead to the destruction of the flexible belt.

It is obvious that in the case of the work equipment machine 62, the occurrence of such sudden accelerations and decelerations of the liquid gasses are substantially prevented by substantially continuously maintaining at least partial flow through each of the inlet and outlet slots or spaces 534 and 536 is. Accordingly, when, as shown in Fig. 62, the flexible belt 70 becomes a *> division, in which the inlet to the outer working chamber 84 and the Aualass from the outer working chamber 84 are closed, continuity of the flow of liquid in the respective inlet and outlet lines the working medium machine is still essentially retained by the fact that the inlet to the inner working chamber 82 and the outlet from the inner working chamber 82 are kept open to Allow fluid to flow. Accordingly, it is to be understood that the deleterious sudden accelerations and delays in the liquid column as mentioned above are essentially prevented here are.

The embodiment of the invention according to FIGS. 63 and 64 is similar to the embodiment according to FIG. 62, by having a housing 530 and a core 532, who work together »for common inlet and outlet passes to form spaces or slots 534 and 536. In this embodiment this is indicated at 538 * flexible band but of a slightly thicker design and it is preferably made of readily available inexpensive material such as rubber or the like. The enlarged Thickness acts to at least partially compensate for the lower tensile strength.

As shown in Fig. 64, the flexible belt 538 with the rotatable drive pin is therethrough Terbied that the latter by one in the tape material formed complementary designed opening 540 passes through it. The ends of the tape are similar connected to fastening bolts 326 and 328 in that the latter is provided with additional band openings pass through and that the protruding fastening bolts ends extend into complementary designed openings in the front panel 6 and • are formed in the rear plate 10.

The mode of operation of the work equipment machine according to FIGS. 63 and 64 is essentially the same like the operation of the Pig embodiment. If, therefore, there is a counterclockwise rotation of the drive shaft 63 is assumed, the slot 534 acts as a common inlet for the outer working chamber and the inner work chamber 82, while the slot 536 acts as a common Aue.1aß for the two working chambers.

Particular advantages of the embodiment according to FIGS. 63 and 64, in addition to the dampening effect of the pulsations of the liquid column, as described above in connection with FIG. 62, are the simplicity and low cost of its implementation. in particular, it should be understood that the use of common inlet and ^a uslaßsohlitze 534 and 556 leads to a considerable simplification and thus to a reduction in the cost of the housing and the core, while t he production of the strip from easily available inexpensive flexible material such as rubber or the like . also leads to a reduction in costs.

A substantial cost saving results from the fact that a slightly more expensive drive pin

009830/1117

connection omitted and by a no cost The formed hole in the plastic tape 558 causing the cause is replaced.

An application for rich the relatively simple and cheap work equipment machine according to the 63 and 64 is particularly suitable, it is used as a dispensing pump for coin-operated dispensing devices, where the pressure requirements of the pump are relatively low.

With the exception of the working medium machine of FIGS. 63 and 64, it can be seen that there is a wide range of suitable pliable metal or plastic materials for satisfactory use in the construction of the pliable belt, the main criterion in the selection of the material being a preference for such materials the great fatigue strength, high flow or yield point, considerable hardness and resistance to corrosion, relatively easy manufacture and convenient Get at reasonable cost to show the relative importance of the rbeitsmittelmaschine these criteria in accordance with the special A _nwe invention, Äür the respective ^ is intended according to the invention can be alleviated.

The criteria for the material or materials which are used in the construction of the housing, the core and the front and rear panels are a matter of course not 3O-seriously like those at applied to the selection of the tape material. Accordingly, essentially any available metal material can be used or plastic material with suitable strength properties and resistance to corrosion in it Respect to be satisfactory.

For general applications as a pump, compressor, medium motor and / or motor-pump combination

009830/1117

For example, steels of high tensile strength and high hardness can be used satisfactorily for the flexible belt including, for example, any of a variety of less intricate steels or plastics one such application for use in making the case, core and faceplate and the back plate can be satisfactory.

Alternatively, for example when using the machine in the food industry or in the chemical processing industry, the flexible tape can be either single-ply or multi-ply from relatively convenient inert plastic material made in the manner of fiberglass and the housing, core and front and rear panels can be made of inert material according to Art be made of reinforced ceramic material.

In general, it should be understood that, except for extremely high speed applications, the weight of the material selected for use in making the flexible belt is not an important factor, it being determined that no more than 51 ° of the Input energy is required to overcome mechanical friction and propel the flexible belt through its cycle of flexural motion. It should also be noted that the width and diameter of the flexible belt can be selected in essentially any ratio that is compatible with the practical overall dimensions of the working medium machine without having an adverse effect on the basic principle of operation of the working medium machine.

The working speed of the working fluid machine according to the invention can be considerably higher than the operating speed of work equipment positive displacement machines because relatively short in the machine according to the Erfindungdas flexible B _a nd by a

009830/111?

St.

Movement path is moved, the speed of movement of the belt from a maximum at the drive pin decreases to zero at the attached tape ends. In addition, there are the weight of the flexible belt as a matter of course very considerably smaller than the weight of working parts such as pistons in the usual back and forth moving work equipment machines with inevitable Displacement or much less than the weight of blades of conventional rotary work equipment machines Inevitable displacement is affecting the machine or the acceleration forces exerted on the belt during work are very considerably smaller, so that a limitation of the operating speed can be neglected for this reason.
