power transmission in Whichia motor, which maybe a constaiit speed motor, operates a pump supplyingliquld under pressure to a liquid motorgdesigned to operate at variable speed,
In mechanisms of this kind known hitherto piston vpumps have been employed they complicate the system very much" because it is necessaryto provide means for reducing the output of the piston pump in proportion, to the consumption of the liquid motor, which varies with its speed. 7
RT his inconvenience is avoided in the subject ofthe present invention'by replacing which the output is selzhlimiting. v

Fig 2 is an end view of the constant speed motor and the centrifugal pumps 2,
Um I drawings show by of example Fig. .3 is an enlarged centrifugal pumps. I In the form of construction shown, a threephase motor- 1, which may be of con.-v
stant speed, is directly coupled to the shaft of three centrifugal pumps placed within the same casing.- The three rote'ry'memhe'r's of the pumps operate in series if the cocks 6; and 7 are closed and cock 8 is opened. The
I pressure is reduced totw'o thirds if the cock Z alone is opened; and a pressure of one detail section of ,the
thilrd can-be obtained by opening the cock 6' s on y,
. The variable speed motor 9 is a motor: I with a piston, which drives, through a connecting rod and crank, the axle 10 ofthetractor. The valve cylinder 11', in'Which reciprocate under the action of the lever 13, is connected on the onehanhl with the pipe '14 by a central port 15, and on the other hand with the pipe 17 by-two. ports 16, one at each end of the -cylinder.- The two pipes 14 and 17.- serve alternatively/"5 as admission and dischargej' pipes-for the motor 9, and for this purpose are'connected to a four-way cockl-S, whichcontrols also the pipe8', by which liquid-"is supplied trom the pumpsgand the pipe 19 by which liquid is'returned to the reservoir 5. According to the position of the c'ock'18 liquid supplied through the pipe 8 may be forwarded through the pipe 14, serving as an admission pipe and returned to the reser- 'voir, throughpipes l7 and 1-9.
