C. power at any time. power. The machine I consists of a hollow body u 21, wherein a number of diaphragms, disks or plates l-24 are arranged. These disks may be of any desired shape, all corresponding to the cross sectional shape of the body 25, although it is natural that a circular shape under most circumstances will be used. The disks I-24 are fixed to the' sides of the body 21 and are electrically insulated in relation to this and to each other. The disks may for this purpose be covered 3y a thin insulated layer of rubber, shellac, enamel or the like. The electric source of power 26 is illustrated with the vectors of E. M. F. which it is adapted to supply.

The machine for supplying this power may very easily be constructed as a phase converter of the stationary type, i. e., a transformer which when fed with a one, twoor three-phase power is adapted to convert this into the number of phases desired.

There is no reason for further describing a machine of this type, as it is generally well known to a man skilled in the art.

Each of the phases of the machine 26 is represented by an arrow, and the phase diierence will be represented by theI angle between the different arrows. When therefore the plates l-24 of the machine 25 are connected to each one of the phases of the source of power as illustrated in Fig. 1, then the contracting action between the plates I-24 will correspond to the phase difierence between the two phases correspondingly connected to the plates which may be illustrated by the difference in distance between the points l-24 on the line 28.

One will here see that the maximum contraction will be present between the plates 1, 8, 9 and i8, i9, 20. These plates will therefore be pulled together, and as the progression of the E. M. F. takes place in the transformer 26, then it may be illustrated as if the transformer 26 were rolling down the sheet, and the contracting power between the plates 6 and 1 will therefore be reduced, while the contracting action between the plates 8 and 9 will b increased; and in the next moment it will be the plates 1, 8, 9 which are contacting with each other, and in the following the plates 8, 9 and l0 and so on, whereby the said caterpillar movements will be produced.

In the plates or disks l-24 there are nonreturn valves as already mentioned, which will be further described with reference to the practical embodiment of the invention which now will be described.

In the embodiment shown in Fig. 2, the body 26, 21 is held in a frame, comprising a head plate 29 and a bottom plate 30 and a, number of bolts 3l. The disks I-24 are shown attached to the body 21 by being clamped between distance pieces 32 and are provided with apertures 34, arranged staggered in relation to each other. In the head plate 29 an inlet opening 35 is arranged, and in the bottom plate 3U an outlet opening 36 is arranged. Electric conducting means l-24' lead to each of the plates |24, which preferably are covered with electric insulating material, as for instance shellac, enamel, rubber or the like. Between each pair of plates I-24, a wedgelike web 31 is arranged which is adapted to ll out the dead space which would be present, if two plates were bent towards each other and such wedge 31 were not present.

The action of the machine as above described will readily be understood from the description of the illustration in Fig. 1. E. M. F. of dii'lerent phase is fed through the leads l '-2", and as this power is changing, the plates I-Zl will be contracted in groups of two, three or more, whereby the holes 34 will be covered and the nuid in front of such group will be forced towards the outlet end 36, as this group is progressing from the inlet end to the outlet end.

The above example was described with reference to an electrostatic embodiment of the invention. In Fig. 3 the same machine is shown with means for electro-dynamic running of the pump. In this ilgure corresponding reference numerals correspond to the same parts as in Fig. 2. The plates |24 are here made of elastic material as for instance rubber and coils 38 are embedded in the same. When electric power is led to these coils from the transformer 26, Fig. 1, the same action will take place as described with reference to this ligure. The plates |24 are here provided with apertures 34, arranged along the same line; therefore' a thin diaphragm 39 also provided with a hole or aperture I0 is arranged on top of each of the plates i-24, and this diaphragm being of elastic material will act as a valve and provide for the nonreturn action.

'I'he embodiment shown in Fig. 4 illustrates another form for the disks I-24. Here the disks are provided with corrugations 4l along the circumference of the same in order to facilitate the swinging action of the same when working.

In the embodiment shown in Fig. 5, the disks l-24 are built up of a middle section of heavy non-resilient material and therearound a. section 42 of thin elastic plate, provided with corrugations. In these two last i'lgures, the remaining reference numerals correspond to the same parts as the reference numerals in Figs. 2 and 3.
