, This invention relates to pumps, and more specifically to a continuous circulating pump of the type used in connection with electric refrigeration apparatus.
The primary object of the invention is to provide a pump of the character mentioned which possesses a minimum of moving parts and which, consequently, can be economically manufactured. I
A further object of the invention is to provide a pum in which vibration during operation is efiectually eliminated, thereby re ducing noise tea minimum.
further object of the invention is to'pror5 vide a pump in which the parts are at all times in substantially perfect balance.
With these and other objects in view, the s is provided andpreferably. carried by the adinventionresides in the features of construction, arrangement of parts, and combiga nations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, in which I Figure l is a longitudinal sectionalview of the invention; v
Figure 2 is a section on, line 2-2, Fig. 1'; Figure 3 is a side elevation (if one of the slidingnheads' of the rotor;. Figures t and 5 are sections on lines 4- 1 and 5-5,;respectively, of Fig. 3.
re 6 is a view similar to Fig. 1 showing a modified form of the invention;
Figure 7 is a section on line 77, F i 6; Figure 8 is a side elevation of one o the sliding ends of the rotor and a Figures 9 and 10 are sections on lines 99 and 10-10, Fig. 8. Referring to said drawings, the reference numeral 1 designates a casing having a pumping chamber formed with an elliptical'inner casing 1 is stationary while a rotor 3 of circular form in cross section is rotatable in the chamber. The rotor has opposite axially disposed journals tand 4 which rotate in the end walls of the casing 1, said journal 4* be'ng lextended outwardly and being adapted or connection with adrive shaftthrouglr which power is communicated for driving said ro tor. The journal 4, as also theinner end circumferential wall 2. In the form of the 1929. SerialNo. 366,610. a
portion of the journal 4*, is made hollow, as shown. A pair of spaced parallel bores or V passages 5 and Gdiametrically' extend across the rotor, the.bore 5-communicating with the interior of the journal 4 and the bore 6 communicating with the interior of the hollow journal 1. Tubular members 7 which are slidably disposed in the opposite ends of each of the bores or .passages 5 and 6 are rigidly carriedfby a head 8, the latter being rotatable with the rotor and. being centrifugally held in seated relation to the walls of the casing 1. Ports 9 and 10. are formed on opposite sides, of each head and communicate with the bores 5 and 6,frespectively, through the interiors of the tubular members 7.
As shown in Fig; '1, an inlet reservoir 11 jacent end of the pump casing. This reservoir has an inlet 12 formed for connection with the source of supply and surrounds the outer end wall of the journal 4:- A reservoir 15 is secured to the opposite end wall of' the pump vcasing and has an exhaust opening 16 thereinfor conveying the fluid to the point of use through any suitable. connection (not shown) j a In order to reduce the friction between the heads and the circumferential wall of the pump casing, the heads are provided with anti-friction rollers 17 which are journaled on the outer surfaces of the heads. The bores or passages 5 and .6 open at their outer ends into transverse channels 18 provided in the periphery of therotor and in which the heads 8 are slidable radially. The tubular members 7 or some of them, have ports 19 therein designed to prevent the formation of vacuum in the channel 18. 5
In the modified form of the invention shown in Figs. .6 to 10, inclusive,the member is stationarily mounted on supports 21 and has its hollow ournals 23 and 24 rigidly secured to the supports by means of set screws 25. -The casing 26 encircles the member. 27 and is driven by a belt28, shown in dotted lines, said belt being engaged over the periphery of the casing.
In this form of the invention the heads 29 areconnected to tubular members 30 and 31,
said members being tensioned by means of coil springs 32, the coil springs being disposed in the bores 33 and at their ends engage the tubular members to normally urge same outwardly thereby to hold the heads 29 in engagement with the elliptical wall of the casing 26. The heads 29 are provided with ports 35, similar to those described in the preferred form of the invention.
In the operation, which is similar in each of the two forms of the invention herein shown, the fluid to be forced by the pump enters the reservoir 11 by gravity, thence passes through the interior of the journal 4, thence in opposite directions through the passage 5 and discharges through the ports of the opposite heads 8 into the pump chamher at the side of the said heads opposite that toward which said heads are being carried in the rotation of the rotor. At the same time, fluid contained by the pump chamber in front of the advancing heads enters the ports 9 and passes thence to the therewith-communicating tubular members 7, thence through the passage 6, thence through the hollow journal 4 to and through ports 14 formed in said journal, whence the fluid entors the outlet reservoir 15, and thence passes to the point of use through the outlet opening 1. In a pump, a casing having an'elliptical circumferential wall, a cylindrical rotor in said casing having oppositely disposed hollow journals rotatably mounted centrally 1n the side wall of said casin g and having spaced diametrical bores opening at opposite ends into the interior of said casing and communicating intermediate their ends with the respective journal interiors, tubular members slidably mounted in the opposite ends of said bores, centrifugally-res onsive heads carried 'by the ad acent tn ular members and occupyin 'seatedrelation to the circumferin the casing having oppositely disposed hollow journals rotatably mounted in the side walls of said casing, said rotor having therein spaced diametrical bores having their opposite ends opening into the interior of the casing, the interior of each journal being in open communication at its inner end with the adjacent bore, centrifugally-responsive members having theirinnerends slidably received in the outer ends of each bore, said members having their outer ends seated upon the circumferential wall of the casing and having ports opening outwardly in opposite directions through which communication is had between said bores and the interior of the casing at both the front and rear sides of said members. W
3. In a pump of the character described, a casing having an elliptical wall, a cylindrical rotor disposed centrally within said casing, axially disposed journals for said rotor rotatably mounted in the opposite side walls of the casing, said rotor having a pair of diametrically disposedv non-communicating passages extending therethrough, the journals having therein axial bores which communicate at their inner ends, respectively, with the thereto adjacent passages, one of said bores constituting a fluid inlet and the other a fluid outlet passage, centrifugallyaesponsive heads occupying seated relation to the circumferential-wall of the casing and having radially directed portions slidably disposed with respect to the adjacent end portions of said diametrically disposed passages, each ofsaid heads having therein ports opening outwardly therethrough in opposite directions, said ports having communication through their said radially directed portions with the said diametrically disposed assages of the rotor.
