PATENT oFFlc-E 2,015,501. ROTARY MACHINE R Otto Sorge, Berlin, Germany Application July 5, 1934, Serial No. 733,847
In Germany February 24, 1932 6 Claims. (Cl. 103-136) This invention relates to rotary engines or machines, in which a rotary body having radial.
slots is Aarranged eccentrically in a stationary casing, and in which radial blades shiftable in said slots are provided with counterpoises counteracting the centrifugal force arising when the rotary body with the blades is in operation. It is known from experience that the known constructions of engines or machines of the type stated cannot run WithV an actually large number of revolutions, say from 2000 to 3000 per minute,v
and, if used as compressors cannot produce an actually high compression, say from 30 to 40 atm., and, if used as vacuum pumps, cannot produce an actually highv vacuum, say from 98 to 99%. 'Ihe object of my invention is to increase the performance of rotary machines of thekind stated so as to render them able to produce that very high compression or vacuum at that very high number of revolutions in continual service. The industry is in need of such high-grade rotary compressors and Vacuum-pumps, and the` want can be,.and is, responded to by my ,present invention.
In investigating the cause for the insutiicient perfomance of the known rotary machines I have discovered that if the blades are combined with counter-poises an essential requirement is to prevent the counter-poised from oscillating while the machine is running. I am aware of the fact that it has already been 'proposed' to 'provide guides for'the counter-paises, but lthe only machine where that has been done is a' single-acting machine which, as such, cannot possibly render a high performance. This requires at least two blades, that is to say, two diametrically located blades having, therefore, diametrically located counter-paises which must be arranged with respect to one another, and also guided relatively to one another, in quite a particular manner. I attain the object in view by arranging and combining themembers concerned in the manner hereinafter described.
The invention is illustrated diagrammatically and by way of example on the accompanying drawing on which Figure -1 is a transverse section through a machine or engine designed according to this invention. Figure 2 is a lateral View of two interengaging'blades, that is t0 say,
blades with their interengaging extensions, cons stitutng the counterpoises, together 'with the- Shaft of the eccentric body (not visible in this 'gure), and Figure 3 is a representation similar to Fig. 2 and shows a inodioation.
On the drawing, c (Figgl) denotes the casing of which are connected with one another at their i sides by disks made integral with trunnions e (Fig. 2)'. In the constructional form illustrated 5 in Figs. 1 and 2 the machine or engine is provided with two blades aand a1 which are located oppositely to one another in a diametrical guide slot, yof the rotatory body d, this slot rendering the body d bipartite. The blades a and a1 have extensions b and b1 reaching across the axis of the body d to the other side and being likewise subject to the centrifugal force arising while the machine or engine is in. operation, but `the centrifugal force arising in4 that portion of each extension which lies on the other side of the axis counteracts the ycentrifugal force arising in the blades and the adjacent portion of each extension, the-dimensionsand masses being so determined that each blade is pressed against the cssing only with such a power asis lust necessary to obtain and maintain the proper ightness at the edges,'thus without any excessive riction and Fig. 1. The solid portionsconstitute the counterpiSeS.
- InY Fig. 2 there are only two blades, and the extensions oi' the same interengage in such a' manner as to guide one another at their sides. It is. however, in sme cases desirable to run the ma- The rods pertaining to the one pairof blades chine or engine with four blades, or with two lcross the rods pertaining tofthe other pair of blades, asappears clearly from said Fig. 3.

other side of the axis and .to their-rigid connection with the blades by the rods b. The counterpoises and the'rods pertaining to one pair of blades alternate .with one another, aszds likewise clearly illustrated in Fig.v 3. There are spaces between the counterpoises of the one blade and which the blade vguide member portions located The rotary body consists in this case, of course,
not only of two parts, but of four, which are likewise rigidly connected with one another by the disks of the trunnions, as shown in dotted lines.
I claim: 1. A rotary machine, comprising a stationary casing, a rotary cylindrical body arranged eccentrically therein and having a slot extending dia- A metrically through it, diametrically opposite blades radially shiftable in the end portions of said slot, blade guide members extending fromv the blades into said slot from the oppositely located blades towards one another and alternating with one another, the blade guide member portions located counter to the appertaining blade on the opposite side of the axis of the rotary body constituting counter-poises for the respective blade.
2. A rotary machine as specified in claiml, in which the blade guide members alternating with one another interengage one another.
3. A rotary machine as specified in claim 1,*in which the blade guide members alternating with one another contact with one another at their sides so as also t0 guide themselves mutually.
4. A rotary machine as specified in claim 1, in
between the appertaining blade and the axis of the rotary body are hollow and the blade guide member portions located counter to the appertaining blade on the opposite side of said axis are solid-so as to constitute the counterpoises.
5. A rotary machine, comprising a stationary casing, a rotary cylindrical body arranged eccentrically therein and having a guide slot ex- 5 `ing to any one of the oppositely located bladesvalternating with the rigid connections pertaining 15 to the other of said blades.
6. A rotary machine, comprising a stationary casing, a rotary cylindrical body arranged eccentric-ally therein and having a plurality of slots extending diametrically through it and crossing one 20 another; a corresponding plurality of pairs of diametrically located blades in the end portions of said slots and being guided therein; i blade counterpoises also guided in said slots counter to the blades concerned on the opposite side of the g5 axis of the rotary body, and rigid connections between the counterpoises and the appertaining blades, the counterpoises pertaining to any one of the oppositely located blades alternating with vthe rigid connections pertaining to the other of I0 said blades, vand the rigid connections pertaining to the several pairs of blades and their counterpoises crossing one another.
