RO'IY PUMP 'llVI'I'H ROTATING BUTMENT PROTRUDING INTO A CIRCULAR GROOVE.
Specification of Letters Patent.
Patented @et 26, 1945.
Application led August 6, 1914. Serial No. 855,526.
lin, Germany, have invented certain newk and useful Improvements in a Rotary Pump with Rotating Abutment Protruding into a Circular Groove.
'Ihe present invention relates to rotary pumps in which the working space has the shape of a circular groove, into which the abutment protrudes laterally, a' sliding distributing device and a closing slide provided with notches allowing of the passing of the abutment.
An executory form of the invention is represented by way of example in the annexed drawing in which:
Figure 1 is a longitudinal section of the machine. Fig. 2 is a transversal section on AwB. Fig. 3 is a longitudinal section of the wheel. Fig. 4 is a cross section of the Wheel on C-D Fig. 5 is a longitudinal section of the body with the working chamber. Fig. 6 is an end view of the body.
In the drawings 1 is the casing, which is tightly closed through the cover 2. In the casing 1 the Wheel 3 is mounted in suitable bearings 4 and 5. The casing is provided with a sucking port 6 leading to the sucking chamber 7, and a pressure-port 8 extending tangentially from the ressure chamber 9. The. body 10 containing the working chamber is rigidly connected with the cover 2. The working chamber has the shape of an annular groove 11.l The body 10 furthermore possesses six radially directed grooves 12 in which can move six closing slides 13, 14, 15, 16, 17 and 18. The closing slides possess recesses 19 allowing of the passing of the abutment 20. The abutment 20 is suspended to the wheel .3, so as to be rotatable on a `pivot 21, and is carried along by it when rotating.
In order-to realize an automatic regulation of the abutment, the pivot 21 is mountedy outside of the center of gravity so that, owing to its centrifugal force, the 'abutment will be pressed with its rear end against the outer 'wall, with its front end against the'inner wall of the working chamber 11. The wheel 3 moves with little play between the face 10 and the rigidly fixed flange 22. It has two canals, a suction-canal 23 and a pressure-canal 24. The suction canal opens in i the shape of a segmental slit toward. the suction-chamber 7, into a circular slit provided around the shaft.
The pressure chamber is provided with a slit 26, also ending in the working chamber 11, at the same time it communicates, through a slit in thel periphery of the wheel, withA the pressure room 9. The inner circumference of the casing 1 is spirally shaped at the places' the pressure channel 24 ends (see Fig. 2, dotted line) so as to form in connection with the flange 27 of the wheel a closed room 8, gradually widening toward the outlet opening 8. The wheel bears the eccentric 28 which, when rotating, moves the f closing slides outwardly. Around the slides is provided a ring 29, the inner diameter of which is equal to the diameter of the eccentric increased of twice the amount of the lengths of the closing slides. In the movement of rotation, the ring is carried along, on the one side through the outwardly moving slide and at the same time the slide provided on the otherside inwardly. This has for a result that all the closing slides are moved reciprocally in a uniform way.
The operation of the machine is thek following: If ,the wheel is being turned in the direction of the arrow, the slides 17 and 18 are moved outwardly by the eccentric 28 into the position shown; the slides 14 and 15 are pressed inwardly by the ring 29, while theslides 13 and l'remain practically stationary. The port of the working chamber between the abutment 20 and the slide 13 into which the suction slit 25 ends, is increased through the movementv of the abutment, while the part of the working chamber into which ends the pressureA slit 26, is reduced. When the wheel has rotated one sixth of a turn the slide 14 will have moved radially far enough to take the position shown for the slide 13, while the slide 15 will have reached the position of the slide 14, and so on.
The same performance is repeated when the rotation continues so that a continuous water now flows through the suction cana-lv 23 which is provided with guide paddles and arrives into the working chamber 11,"`
@whence it is forced by the abutment through the forcing canal 24 which also has the shape of a guide paddle into the pressure chamber 9. From this chamber which has` a spiral shape, the waterarrves, through the forcing connection into the forcingY pipe.
The machine is shown on the drawing as a unilaterally working one. Obviously it may also be built as a double one by either arranging the wheel between two covers and working chambers of the same shape or two working chambers between two identical Wheels.
I claim;
1. A pump, including a rotor casing, a rotor, radially movable slides, mounted vwithin the casing, means, carried by the rotor, adapted to bear against the inner edges of said slides to project them and means, comprising an annular band, adapted to engage their opposite edges for retracting them.
2. A pump, including a rotor casing, a rotor, radially movable slides, mounted within the casing, means, carried by the rotor, adapted t0 bear against the inner edges of said slides to project them and an annular band disposed to incase the slides for retracting them.
3. A pump comprising a rotor casing, a rotor having an abutment pivotally mounted thereon, radially movable slides formedv with openings through their body portions mounted within the casing, the abutment formed upon said rotor being movable through the openings inthe slides.
4. A pump, comprising a rotor casing, a rotor having an abutment pivotally mounted thereon, said abutment being suspended to one side of its center of gravity, radially movable slides formed with openings through their body portion, mounted within the casing, the abutment formed upon said rotor being movablethrough the openings in the slides.
In testimony whereof I have hereunto' set my hand in presence of two witnesses.
