To all whom it may concern/.-
Be it known that I, SIEGFRIED Manoos, a subject of the Emperor of Austria, residing Empire, have invented certain new and use ful Improvements in Rotary Engines and Pumps and I do hereby declare 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 to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
My invention relates to improvements in rotary pumps adapted for use as amotor; and it consists in the construction and arrangement of parts, substantially as hereinafter more fully described, and specifically pointed out in the claims.
In the accompanying drawings, Figure 1 is an elevation showing the internal construction of my improved pump, one cylinder-head betal transverse section thereof, taken on line a- ;1 of Fig. 1. Fig. 3 is alike view, showing a modified arrangement for operating the pump 5 and Fig. 4 is an insideface view of one of the cylinder-heads.
In the above figures of drawings like letters of reference indicate like parts.
O is the pump-cylinder, and H H the heads thereof, supported upon any suitable base, B. The head H has inlet and outlet passages I 0, respectively, and recesses h h, for purposes hereinafter described. WVithin the cylinder is located a ring, R, toothed upon its interior periphery, with the teeth of which meshes a toothed wheel, W, of less diameter than the toothed ring. Both the wheel and ring extend from one cylinder-head to the other, as shown in Figs. 2 and 3. The cylinder is di vided into two chambers, c c, by the wheel W and by a segmental partition, P, in the space between said wheel and the ring R. The outer periphery of the partition 1? is a segment of the circle described by the crest of the teeth of the ringR, and the inner periphery a segment of the circle described by the crest of the teeth t of the wheel WV, said partition P being attached to the heads of the cylinder 0. The wheel W is mounted upon and rotated by a shaft, S, either by hand or from any ,desired prime motor, and communicates its movement to the ring R,which rotates within the cylinder.
The inlet-orifice I and the recess h of the eylinder-headH communicate with the chamber 0 of the cylinder, and the outlet-orifice O and rewater. In this manner the water entering at I is transferred to chamber 0, and, as will be observed, the chamber 0 increases in area in the direction of rotation of the wheel and ring, or from the point of engagement of the two to the partition I while that of the chamber 0 decreases in area in the said direction of rotation, whereby a partial vacuum is created in chamber 0 and fluid drawn in, while the fluid carried over to chamber 0 is compressed and forced out through the outlet-orifice. All fluid between the interdental spaces on the-side of the suction-chamber is forced through the reeess h into said chamber.
It is evident that when the movement of the pump is reversed the inlet and outlet orifices and the chambers c 0 have their functions correspondingly reversed, and the recess in then serves to conduct the water from the interdental spaces to the left of the point of e11- gagement of the wheel and ring to the chamher 0, which is now the suction-chamber.
It is also evident that the recesses h h may be formed in the body of the cylinder or in the opposite head, and thatinstead of imparting motion to the wheel W motion may be imparted to the ring B. This latter may be effected in a very simple manner, as shown by Fig. 3, in which a disk, D, mounted upon the driving-shaft S, is connected with the ring R,
or formed with such ring, and the wheel W is mounted upon a counter-shaft, S, rotating with the Wheel in its bearings.
If the inlet-passage is connected to a supplymain and a liquid supplied to chamber 0 under pressure, the pump may be used as a motor, as will be readily understood.
Having now described my invention, what I claim is- 1. In a rotary pump, a pumpcy1inder having the suction and delivery ports formed in one of the heads thereof, an internally-toothed ring arranged to rotate in contact with the interior periphery of such cylinder, in combination with a pinion meshing with said ring, and a diaphragm or partition interposed between the pinion and ring, dividing said cylinder into a suction and discharge chamber, substantially as and for the purposes specified.
