l Specification of Letters Patent.
-Patentetl Jun@ 1,1909.
l il, 4Atp;nation med october 1, 190s. sea; No. came ',Toall'iuihom it muy concern:y
Be it known that I, GUsTAv. MEYERSBERG, Bngineena subject. of the Emperor of Austria and a resident of Berlin, Barbarossastrasse 25, in theEmpireof Germany, have invented certain new and useful Improvements in an Expansion-Motor, and do hereby decla-re the following to be a full, clear, and' exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same, reference bein had to the accompanying drawings, and to etters of references 'marked thereon, which form a part of this specification.
Itv is already known to conduct a mixture of liquid and gas or steam from a high pressure chamber to a chamber of lower pressure, so that the gas which is carried along with the liquid ex ands and the energy of expansion thus set' ree serves for increasing the energy of the moving column of the mixture. By far the larger part of this energy is found at theend of the operation in theV liquid while the gas only takes with itquite asmall iraction of the energy. The ap aratus with out-can be termed a hydraulic expansion apparatus or ahydraul-ic expansor.
`A liquid whichl has been furnished with energy in this manner can be employed for driving motorsif it is allowed to act upon the movable portion of the motor (such as the turbine Wheel or the like) .and wholly or partly'expend itsenergy thereon. The mixture ofl liquid and gas can be allowed toV stream directly from the expansor upon the turbine wheel: so-that the liquid and gas can act upon it together.y `This. method ofoperating a motor possesses the advantage over the direct action of a .moving column of gasor vaporupon the turbine. that aconsiderably lower speed of revolution'and fewer stages are necessary. l.The liquid moves with the same amount' of energy considerably more slowly than gas or vapor, so that a smaller peripheral speed ofthe. turbine is necessary.
A further advantagewhich is particularly noticeable in the use of' gas lturbines consists in the fact that it is not necessary to brine` the hot gases of combustion into contact with the moving parts of the motor. It is true that the hot gases come into contact with the metal sides ofthe expansor but they only remain there for a very short time. Moreover the passage ways of the expansor are very conslderably cooled by the constantly owcles expand and ing liquid. The liquid after it hasdone work in the motor can be led back again to the ex'- pansor. It can be freedi at one'or more points mits circuit from the heat which it has acquired by coming into contact with the hot gases and' the heated sides 'of the Y apparatus as well as by the loss of energy during its passage. The whole process can be carried out by cycles ofthe expansor being'made to synchronize with the cycles of the motor or being independent of them. j
The invention is'illu'strated in the accompanying drawings in which al turbine motor is shown by way of example.
Figure 1 is a section of the apparatus, and- Fig. 2'is a section of a part thereof'taken on the line g/-fy of Fig. 1.
The turbine Wheel a is'previded with two'- sets of passage ways. The inner set b and c enable the wheel a to Abe workedzv after the manner of a pressure pump, the outer set d making it act as an impulse turbine. Through the pipe e there streams water at a pressure` p1 which passes through the circular passages' l) and is thereby brought to the higher pressure p2 which exists at. the outer periphery of the passages b and in the space f5-f. Between the passages b is a second series of pasje-j sages c for` the passage ofthe gassy medium.
In the present'instance it is assumed-'that steam is -used fwhich leaves theboiler' at, 'a pressure p2 and passes through the pipe gto the annular chamber f-f. Fromthisl chamber it passes into thepassages c, which 'open on one side toward f, and it passes through these passagesbetween the streams of waterl leaving the passages b. lThev section shown in Fig.l 1 is-taken so that a passage for the water can be seen in the upper half of the Wheel c and a passage for the steam in' the lower half.` "From the passages b the water passes to a ring of iixed directing or guideA passages h"(the expansor). They dividing partitions of'these passages are beveled atV ytheir inner edges and divide the streams of water into separate sections between which the steam coming from the passages c enters.Y
The turbine wheel is surroundedbby a chamber t in which-thereis a pressure p1 which isl lower than p2. There consequently takes place in the passages h an expansion of the moving column of mixture from the pressure p2 to the pressure p1. The steam particles which arecarried between the Water partiqluicken the passage ofthe water particles.
hese latter now enter the 'applic to a single wheel.
the passage c to the exhaust, or is led 0H into a condenser or for use in another cycle of operations. The water is led off through the pipe l and can be led back again for further use in the apparatus through the pipe e.
In Fig. 1 the pressure pump passages and the im ulse turbine passages are both shown It may however be found advantageous to form these two sets of passages in independent bodies. The essential feature is that the ring or segment of expansor passages should lie immediately between the two rotating sets of passages, so that they can serve simultaneously both as directing passages from the pressure pump assages and as nozzles for the impulse turbine passages. The passages c may also be replaced by an annular air space.
The direct connection of the two wheels,
besides offering the advantages of reducing space, has the further purpose of reducing to a minimum the loss of energy in the passage from one wheel to another.
That, what I claim is'.
1. Ina motor driven by means of a moving column of fluid composed partly of a liquid and partly of gas or steam, a passage for the admittance of the liquid, a passage v for the admittance ofthe gas or steam, a
wheelA portion adapted 'to rotate, a series of alternatively disposed ygas and liquid passages in said wheel portion, andin communication respectively with said gas and liquid admittance passages, a series of directing passages arranged adjacent to the exits from the passages in the wheel portion and a series of passages also formed in a wheel portion of the motor yadapted to rotate and arranged about the, directing passages and adapted to receive the jets of mixed liquid and gas or steam which leave the directing passages, substantially as described.
